The position of the particle at time t = 1 would be -1.

To find the position of the particle at time t = 1, we need to integrate the velocity function v(t) from t = 0 to t = 1, and add it to the initial position x = -2:

x(1) = -2 + ∫[0,1] v(t) dt

Integrating v(t), we get:

x(1) = -2 + ∫[0,1] (6t² + 8t - 5) dt

x(1) = -2 + [2t³ + 4t² - 5t] from 0 to 1

x(1) = -2 + [2(1)³ + 4(1)² - 5(1)] - [2(0)³ + 4(0)² - 5(0)]

x(1) = -2 + [2 + 4 - 5]

x(1) = -2 + 1

x(1) = -1

Therefore, the position of the particle at time t = 1 is -1.

Assuming you meant "x - 2(x - 2) * 3" as the expression, here is how you can simplify it:

= x - 2(3x - 6) // Distribute the 2

= x - 6x + 12 // Distribute the -2

= -5x + 12 // Simplify

Therefore, the simplified expression is -5x + 12.

To simplify the expression "x subtract 2 x subtract 2 multiply 3," we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, we need to simplify the multiplication by 3 inside the parentheses:

Next, we can simplify the subtraction of 2x:

-x - 2(3)

Finally, we can simplify the multiplication of 2 and 3:

-x - 6

Therefore, the simplified expression is "-x - 6".

Answer:

A. 6, 7 , 8, 9 and 15

B. 1, 3, 5, 7 and 19

Step-by-step explanation:

please see the attached I put.

The sides of the triangle are a ≈ 8.3, b = 7, and c = 10, and the angles are A = 51°, B ≈ 51.5°, and C ≈ 77.5°.

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles.

To solve the triangle, we need to find the values of the remaining sides and angles. We can start by using the Law of Sines, which states that:

a / sin A = b / sin B = c / sin C

where a, b, and c are the sides of the triangle, and A, B, and C are the angles opposite to those sides.

Using the given values, we can write:

a / sin 51 = 7 / sin B

a / sin 51 = 10 / sin C

To solve for a, we can use either of the two equations above. Let's use the first one and solve for sin B:

sin B = (7 / sin 51) * sin B

sin B = 7 / (sin 51 / sin B)

sin B = 7 / sin(180 - 51 - B)

sin B = 7 / sin(129 - B)

Using the sine rule, we can determine the angle B:

sin B / 7 = sin(129 - B) / 10

sin B = (7/10) * sin(129 - B)

sin B = (7/10) * (sin 129 * cos B - cos 129 * sin B)

sin B = (7/10) * sin 129 * cos B - (7/10) * cos 129 * sin B

(7/10 + (7/10) * cos 129) * sin B = (7/10) * sin 129 * cos B

sin B = (7/10) * sin 129 * cos B / (7/10 + (7/10) * cos 129)

sin B = sin 51.5

B = sin(sin B)

B = sin(sin 51.5)

B ≈ 51.5°

We can now find the remaining angle, C:

C = 180 - A - B

C = 180 - 51 - 51.5

C ≈ 77.5°

Finally, we can use the Law of Sines again to find the remaining side, a:

a / sin A = c / sin C

a / sin 51 = 10 / sin 77.5

a = (10 * sin 51) / sin 77.5

a ≈ 8.3

Therefore, the sides of the triangle are a ≈ 8.3, b = 7, and c = 10, and the angles are A = 51°, B ≈ 51.5°, and C ≈ 77.5°.

Answer:

  "time and a half" workers were paid 50% more per day

Step-by-step explanation:

You want to know the relative daily pay rates of laborers making time and a half versus those who were not. 4 getting time and a half and 20 not earned a total of $2080, while 2 getting time and a half and 15 not earned a total of $1440.

We can let x and y represent the daily pay of time and a half workers, and those not earning time and a half. The two payrolls can be described by ...

  4x +20y = 2080

  2x +15y = 1440

Subtracting the first equation from 2 times the second, we have ...

  2(2x +15y) -(4x +20y)  = 2(1440) -(2080)

  10y = 800 . . . . . . . simplify

  y = 80 . . . . . . . . . . divide by 10

  2x +15(80) = 1440

  2x = 240 . . . . . . . . . . subtract 1200

  x = 120 . . . . . . . . divide by 2

Workers getting time and a half made $120 per day; workers not getting time and a half made $80 per day. Workers getting time and a half made half again as much as those who didn't: $40 per day more, or 50% more, or half-again as much.

__

Additional comment

"Time and a half" means the pay is 50% more. That's what we see here. You don't need any math to say those getting time and a half were getting 50% more per day.

The solution to the triangle is: a ≈ 22.4, b = 4 , c ≈ 77.2 ,A = 27° ,B ≈ 42.5°

C ≈ 110.5°  we got the answer by using law of sine

what is  law of sine?

The Law of Sines, also known as the Sine Rule, is a mathematical formula used in trigonometry to relate the sides and angles of a non-right-angled triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.

In the given question,

Using the law of sines and the fact that the angles of a triangle sum up to 180 degrees, we can solve for the missing parts of the triangle:

sin(A)/a = sin(B)/b = sin(C)/c

sin(27)/a = sin(B)/42 = sin(C)/72

We can use the first equation to solve for a:

a = b(sin(A)/sin(B)) = 42(sin(27)/sin(B)) ≈ 22.4161

Next, we can use the second equation to solve for sin(B):

sin(B) = b(sin(A)/a) = 42(sin(27)/a) ≈ 0.6822

Taking the inverse sine, we find that B ≈ 42.4827 degrees.

Now we can use the fact that the angles of a triangle sum up to 180 degrees to solve for C:

C = 180 - A - B ≈ 110.5173 degrees.

Finally, we can use the law of sines again to solve for the remaining side, c:

c = a(sin(C)/sin(A)) = 22.4161(sin(110.5173)/sin(27)) ≈ 77.2352

Therefore, the solution to the triangle is:

a ≈ 22.4

b = 42

c ≈ 77.2

A = 27°

B ≈ 42.5°

C ≈ 110.5°

Therefore, the probability that AT LEAST ONE of them has been vaccinated is 0.98693

If 58% = 58÷100 of the people have been vaccinated, then;

1 - (58/100) = 42% = 42÷100 of the people who have not been vaccinated.

Now:

Probability, P( > 1 ), that at least one of the selected four has been vaccinated is given by;

P( > 1 ) = 1 - P(0)                 -----------(1)

Where;

P(0) = probability that all of the four have not been vaccinated.

P(0) = P(1) x P(2) x P(3) x P(4)×p(5)

Where;

P(1) = Probability that the first out of the four has not been vaccinated

P(2) = Probability that the second out of the four has not been vaccinated

P(3) = Probability that the third out of the four has not been vaccinated

P(4) = Probability that the fourth out of the four has not been vaccinated

P(5)=Probability that the fifth out of the five has not been vaccinated

Remember that 42÷100 of the population has not been vaccinated. Therefore,

P(1) = 42÷100    

P(2) = 42÷100

P(3) = 42÷100

P(4) = 42÷100

P(5)=42÷100

P(0) = (42÷100) x (42÷100) x (42÷100) x (42÷100)×(42÷100)

P(0) = (42÷100)⁵

P(0) = (0.42)⁵

P(0) = 0.013067

Therefore, from equation (1);

P( > 1 ) = 1 -0.013067

Answer: No, you cannot always divide by e^x. When e^x equals zero, dividing by it would result in an undefined value or division by zero error.

For example, consider the function f(x) = e^x. We know that e^x is never equal to zero for any value of x. Therefore, we can always divide by e^x for any value of x, and the resulting quotient will be well-defined.

However, if we consider the function g(x) = 1 / e^x, we cannot always divide by e^x. When e^x equals zero, g(x) will be undefined. In fact, there is no value of x for which e^x is equal to zero, so the function g(x) is well-defined for all values of x.

In summary, dividing by e^x is allowed for most cases, except when e^x equals zero.

a. FPCF for this sample is FPCF = √(199/24) = 2.89.

b. The population cannot be considered effectively infinite, so the answer is no.

When the sample size is significant compared to the size of the community, the Finite Population Correction Factor, also known as the FPC factor, is applied. The population in most cases is so vast that typical sample sizes are insufficient to raise concerns about the need for the FPC.

The recommendation is to use the FPC when the sample size to population size ratio is higher than 5%. The FPCF must be used, for instance, if the population number is 300 and the sample size is 30, which results in a ratio of 10%.

a. To calculate the FPCF (finite population correction factor) for this sample, we can use the formula:

FPCF = √(N/n)

where N is the population size, and n is the sample size.

In this case, N = 199 (the number of blood samples in the racks), and n = 24 (the number of samples selected every seventh blood sample).

FPCF = √(199/24) = 2.89 (rounded to two decimal places)

b. To determine whether the population should be considered effectively infinite, we need to compare the sample size to the population size. A general rule of thumb is that the population can be considered effectively infinite if the sample size is less than 5-10% of the population size.

In this case, the sample size is 24, which is approximately 12% of the population size of 199. Therefore, the population cannot be considered effectively infinite, and the FPCF should be applied to adjust for the finite population size.

The area of the shaded region is 1.916 ft²

Area is a measure of the amount of space inside a two-dimensional shape, such as a square, rectangle, triangle, circle, or any other shape that has a length and a width. It is usually measured in square units, such as square inches, square feet, or square meters.

To calculate the area of the shaded region, we need to find the area of the entire circle and subtract the area of the unshaded portion.

The central angle corresponding to the shaded region is 110 degrees. The entire circle has a central angle of 360 degrees.

The unshaded portion of the circle is the sector that corresponds to the central angle of 360 - 110 = 250 degrees. The area of a sector of a circle with radius r and central angle θ is given by the formula:

A = (θ/360)πr²

Substituting θ = 110 degrees and r = 2 ft, we get:

A = (110/360)π(2)

A =  (0.305)π(2)

A =  (0.305)π(2)

A = 0.61π

A = 1.916 ft²

For the given cone, the approximate volume of the toy top is 106.81 cubic centimeters. The three dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex.

Volume is a three-dimensional quantity that measures the amount of space occupied by an object or a region in space.

The volume of the toy top can be calculated by finding the volumes of the cone and cylinder and then adding them together.

The volume of the cone is given by the formula V = (1/3)π[tex]r^{2}[/tex]h, where r is the radius and h is the height of the cone. In this case, the slant height is given, so we need to use the Pythagorean theorem to find the height:

h = [tex]\sqrt{(l^2 - r^2)[/tex] = [tex]\sqrt{(10^2 - 6^2)[/tex] = √(64) = 8 cm

Therefore, the volume of the cone is:

V_cone = (1/3)π[tex]r^2[/tex]h = (1/3)π([tex]6^2[/tex])(8) ≈ 100.53 [tex]cm^3[/tex]

The volume of the cylinder is given by the formula V = π[tex]r^2[/tex]h, where r is the radius and h is the height of the cylinder. In this case, the diameter is given, so we need to divide by 2 to get the radius:

V_cone = (1/3)πh = (1/3)πr = d/2 = 1 cm = 2 cm

Therefore, the volume of the cylinder is:

V_cylinder = π[tex]r^{2}[/tex]h = π([tex]1^{2}[/tex])(2) ≈ 6.28

The total volume of the toy top is:

V = V_cone + V_cylinder ≈ 100.53 + 6.28  ≈  106.81 T

Therefore, the approximate volume of the toy top is 106.81 cubic centimeters.
