Thus, the time taken by Colby to travel at each speed is-

5 hours at 12 mph and 6 hours at 10 mph.

In the study of physics, the three key variables are speed, distance, and time. How quickly or slowly an object moves through one point to another is determined by the concept of speed. The distance travelled in a unit of time is referred to as speed. Distance is exactly proportional to velocity and speed, while time is constant.

The formula for speed:

speed = distance/time

Then ,

time = distance / speed

Let speed S1 = 12 mph , for this time taken t1.

Let the speed S2 = 10 mph , for this time taken t2.

Since, in each distance is same say 'd'.

Total time t = 11 hours.

t = t1 + t2

t = d/s1  + d/s2

11 = d(1/12  +  1/10)

11 = d(12+10) / (12*10)

d = 11*120 / 22

d = 60 miles.

t1 = 60/12 = 5 hours

t2 = 60/10 = 6 hours.

In the given equation the value of mº is 17°. Answer: (D) 49 = 32° + mº.

A triangle is a geometrical figure with three straight sides and three angles. It is the simplest polygon and the building block for more complex shapes.

There are several kinds of triangles:

Equilateral triangle: This is a triangle with three equal sides and three equal angles of 60 degrees each.

Isosceles triangle: This is a triangle with two equal sides and two equal angles.

Scalene triangle: This is a triangle with no equal sides or angles.

Right-angled triangle: This is a triangle with one angle of 90 degrees, which is also known as the right angle. The side opposite to the right angle is the longest side, called the hypotenuse, while the other two sides are called legs.

Acute triangle: This is a triangle in which all three angles are acute angles, meaning they are less than 90 degrees.

Obtuse triangle: This is a triangle in which one angle is an obtuse angle, meaning it is greater than 90 degrees. The other two angles are acute angles.

The equation that can be used to solve for mº depends on the given information or conditions. If the problem provides the measures of two angles and their sum, then we can use the equation:

A + B + m = 180°

where A and B are the measures of the given angles, and m is the measure of the unknown angle in degrees.

However, if the problem only gives the measures of two angles and their sum is not required, we can use the equation:

A + B = m

where A and B are the measures of the given angles, and m is the measure of the unknown angle in degrees.

Based on the given information in the question, we are only provided with the measures of two angles, 49° and 32°, and there is no indication that their sum is required. Therefore, the correct equation to solve for mº is:

49° = 32° + mº

We can simplify this equation to solve for mº:

49° - 32° = mº

mº = 17°

Therefore, the value of mº is 17°. Answer: (D) 49 = 32° + mº.

Answer:

m∠A = 50°

m∠B = 40°

AB = 15.5 units

Step-by-step explanation:

This is a right trangle, so we can use the Pythagorean Theorem to calculate AB.

AC² + BC² = AB²

AB² = 11.9² + 10²

AB² = 141.61 + 100

AB = √241.61

AB ≈ 15.5 units

Since this is a right triangle, we only need the angle measurement of either m∠A or m∠B to calculate the angle measurement of the other.

I will use sine function to calculate the angle measurements of A and B. Try to use a more precise value for AB than the rounded answer so our angle measurement will be closer to the actual angle.

sin(m∠B) = 10/15.54381

m∠B = sin⁻¹(10/15.54381)

m∠B = 40.04°
Round to nearest tenth, so m∠B = 40°

m∠A + m∠B + 90° = 180°

m∠A + 130° = 180°

To find [fo(hog)] (1), we need to first evaluate the composition hog at x = 1, and then plug the result into f.

Let's start by evaluating hog at x = 1:

hog(x) = h(g(x)) = h(x + 4) = (x + 4)^2 - 1

So, hog(1) = (1 + 4)^2 - 1 = 24

Now we can evaluate f at hog(1):

f(hog(1)) = f(24) = 3(24) = 72

Therefore, [fo(hog)] (1) = 72.

Answer:

The function f(x) = x represents a straight line with a slope of 1, passing through the origin (0,0).

If we consider the interval from x = 2 to x = 9, we can see that the line starts at f(2) = 2 and ends at f(9) = 9.

Therefore, over the interval from x=2 to x=9, the function f(x) = x increases in a straight line fashion from 2 to 9.

In other words, the slope of the line is positive, and the function is monotonically increasing on this interval.

The given expression is,

-1/6+2/3(9-3/4)-1/2

According to BODMAS rule, we first do the operation of bracket ( as B comes first in the BODMAS).

∴ 9-3/4= (36-3)/4=33/4

Putting 33/4 in place of (9-3/4), the expression becomes

-1/6+2/3×33/4-1/2

Now, the priority of M in BODMAS is more than A and S, so we do the operation of multiplication.

∴2/3×33/4=11/2 ( as 33÷3=11 and 4÷2=2)

Replacing 2/3×33/4 by 11/2, the expression becomes,

-1/6+11/2-1/2

= -1/6+(11-1)/2

Step-by-step explanation:

The solutions to the original equation are x = 2nπ, where n is an integer.

A trigonometric identity is an equation that is true for all values of the variables within the domain of the functions involved.

We can use the trigonometric identity cos(2x) = cos²(x) - sin²(x) to simplify the left-hand side of the equation:

cos(2x)cos(x) - sin(2x)sin(x) = (cos²(x) - sin²(x))cos(x) - 2sin(x)cos(x)sin(x)

Simplifying further using the identity sin(2x) = 2sin(x)cos(x), we get:

(cos²(x) - 3sin²(x)cos(x)) + sin(2x) = 1

Substituting sin(2x) = 2sin(x)cos(x), we get:

cos³(x) - 3sin²(x)cos(x) + 2sin(x)cos(x) - 1 = 0

We can factor this expression as follows:

(cos²(x) - 1)(cos(x) - 2sin(x) + 1) = 0

The first factor has solutions cos(x) = ±1, which means x is an integer multiple of π/2. However, these solutions do not satisfy the original equation, since the left-hand side is always equal to zero.

The second factor gives us the equation cos(x) - 2sin(x) + 1 = 0. We can rewrite this as:

cos(x) + 1 = 2sin(x)

Using the identity sin²(x) + cos²(x) = 1, we can square both sides of this equation to get:

1 + 2cos(x) + cos²(x) = 4sin²(x)

Substituting sin²(x) = 1 - cos²(x), we get:

5cos²(x) - 4cos(x) - 3 = 0

This quadratic equation can be factored as:

(5cos(x) + 3)(cos(x) - 1) = 0

The first factor gives us the solution cos(x) = -3/5, but this is not a valid solution since the cosine function only takes values between -1 and 1.

The second factor gives us the solution cos(x) = 1, which means x is an integer multiple of 2π.

Therefore, the solutions to the original equation are:

x = 2nπ, where n is an integer.

To find out how many plants will be left over after putting them in 7 equal rows, we need to divide the total number of plants (438) by the number of rows (7) and then find the remainder.

We can use integer division to find out how many plants will be in each row:

438 ÷ 7 = 62

So each row will have 62 plants.

To find out how many plants will be left over, we can subtract the total number of plants from the product of the number of rows and the number of plants in each row:

By answering the presented question, we may conclude that As a result, surface area the prism's surface area is 640 square feet.

The surface area of an object indicates the overall space occupied by its surface. The surface area of a three-dimensional form is the entire amount of space that surrounds it. The surface area of a three-dimensional form refers to its full surface area. By summing the areas of each face, the surface area of a cuboid with six rectangular faces may be computed. As an alternative, you may use the following formula to name the box's dimensions: 2lh + 2lw + 2hw = surface (SA). Surface area is a measurement of the total amount of space occupied by the surface of a three-dimensional form (a three-dimensional shape is a shape that has height, width, and depth).

To get the surface area of the prism, sum the areas of all six faces.

The top and bottom rectangular faces have the same size and area:

10 feet x 8 feet = 80 square feet

The dimensions of the other four faces are the same:

12 feet tall x 10 feet wide = 120 square feet

As a result, the total surface area is:

2 (80 square feet) + 4 (120 square feet) = 160 square feet + 480 square feet = 640 square feet

Tom: 5C - 2(5S) = P1

John: 3(5C) - 13C = P2

where P1 and P2 are the profits made by Tom and John, respectively.

We know that at the end of the business day, John banks Ksh 110,000/- while Tom banks Ksh

P1 = 230,000 - 5C

P2 = 110,000 - 18C

Substituting these values into the equations for Tom and John, we get:

5C - 2(5S) = 230.000 - 5C

Simplifying these equations, we get:

10C - 10S = 230,000

2C = 110,000

Solving for C, we get:

C = 55,000

Substituting this value back into the first equation, we can solve for S:

10(55,000) - 10S = 230,000

A Maclaurin series, named after the Scottish mathematician Colin Maclaurin, is a special type of power series expansion of a function that is centered at zero. In other words, it is a way to represent a function as an infinite sum of terms that involve the function's derivatives evaluated at zero.

The general form of a Maclaurin series for a function f(x) is given by:

[tex]f(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 + ...[/tex]

To evaluate the function f(x) = x^2 * [tex]e^x[/tex] using Maclaurin series, we can first find the Maclaurin series for [tex]e^x[/tex] and then multiply it with x^2 to obtain the Maclaurin series for f(x).

The Maclaurin series for [tex]e^x[/tex]is given by:

[tex]e^x = 1 + x + x^2/2! + x^3/3! + x^4/4! + ...[/tex]

Multiplying both sides by x^2, we get:

[tex]x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]

Therefore, the Maclaurin series for f(x) is:

[tex]f(x) = x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]

To approximate the value of f(x) using the Maclaurin series, we can truncate the series after a certain number of terms. The more terms we include, the more accurate the approximation will be. For example, if we use the first three terms of the series, we get:

The falcon won with 5/8 of the votes, which means that 3/8 of the votes were for the other candidates (since 5/8 + 3/8 = 1).

Let's represent the total number of votes as "x".

Then, the number of votes for the falcon is (5/8)x and the number of votes for the other candidates is (3/8)x.

Out of these other candidates, the eagle received 1/3 of the votes. So, the number of votes for the eagle is:

(1/3)(3/8)x = (1/8)x

We know that the total number of votes is 536, so we can set up the equation:

(5/8)x + (3/8)x + (1/8)x = 536

Simplifying the equation, we get:

(9/8)x = 536

Multiplying both sides by 8/9, we get:

Counting the number of places we move the decimal point, we get:

93,000,000 = 9.3 x 10^7

Therefore, 93 million miles can be written in scientific notation as 9.3 x 10^7 miles.

Step-by-step explanation:

Thus, the total earning of Margot during summer is found to be $500.

Although the usage of percent and percentage differs slightly, they both signify the same thing. It is customary to use percent or the symbol (%) along with a numerical value.

Although the percentage word was not very ancient, the technique was often used. The Ancient Romans used to calculate fractions as multiples of 1/100 in the absence of the decimal system.

Given :

So,

12% of x =  60.00

x = 60.0 * 100 / 12

x = $500

Total earning amount = $500

Thus, the total earning of Margot during summer is found to be $500.

Correct question:

Margot gave 12% of x number of dollars that she earned over the summer to an animal rescue shelter.

12% of x is about $60.00. Find the total earning of Margot during summer.

the given pairs of functions are inverse of each other.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.

We have two function

f(x) = √(x+4)+9

let y=√(x+4)+9

y-9=√(x+4)

(y-9)²=x+4

x=(y-9)²-4

inverse of f(x) is (x-9)²-4

Now for g(x)= (x-9)²-4

The inverse of g(x)
will be f(x) = √(x+4)+9

Hence the given pairs of function is inverse of each other

Answer: If the height of seven and three fourths yards and a base of 20 yards, then the area of the right triangle is 77.5 square yards.

To calculate the area of a right triangle, we can use the formula:

Area = (base * height) / 2

where the base is one of the sides of the triangle, and the height is the perpendicular distance from that side to the opposite vertex.

In this case, the height of the right triangle is 7 and 3/4 yards, and the base is 20 yards. Plugging these values into the formula, we get:

Area = (20 * 7.75) / 2 = 155 / 2 = 77.5 square yards

In summary, to calculate the area of a right triangle, we can use the formula that relates the base and height to the area. In this case, we needed to use the given values of the height and base of the right triangle to compute the area in square yards.

The resulting area represents the amount of surface inside the triangle and is useful in many applications, such as geometry, physics, and engineering.
