O is between M and P. If OM = 11 and PO = 14, find the length of MP
Answers
According to the given information, we can draw the following
As you can observe in the image, MP is formed by OM plus PO by the sum of segments theorem, so using the given information, we have
\(\begin{gathered} MP=OM+PO \\ MP=11+14=25 \end{gathered}\)Therefore, the length of MP is 25 units.

Apply the convolution theorem to find the inverse Laplace transform of the given function. 2/(s^2+81)^2
Answers
The function in terms of its partial fractions. The inverse Laplace transform of 2/(s^2+81)^2 is 2te^(-9t)cos(9t) - 2te^(9t)cos(9t).
To apply the convolution theorem to find the inverse Laplace transform of the function 2/(s^2+81)^2, we first need to express the function in terms of its partial fractions.
The given function can be written as: 2/(s^2+81)^2 = A/(s+9i)^2 + B/(s-9i)^2 Where A and B are constants. Now, we need to find the values of A and B. To do this, we can multiply both sides of the equation by (s+9i)^2 and substitute s = -9i: 2 = A + B/(s-9i)^2 2 = A + B/(-18i)^2 2 = A + B/324 From this equation, we can find A = 2 and B = -324.
Now, we can find the inverse Laplace transform of each term separately. The inverse Laplace transform of A/(s+9i)^2 is 2te^(-9t)cos(9t), and the inverse Laplace transform of B/(s-9i)^2 is -2te^(9t)cos(9t).
Therefore, the inverse Laplace transform of 2/(s^2+81)^2 is 2te^(-9t)cos(9t) - 2te^(9t)cos(9t).
In summary, the inverse Laplace transform of the given function is 2te^(-9t)cos(9t) - 2te^(9t)cos(9t).

The point P = (-5/3 squared, y) lies on the unit circle shown below. What is the value of
y in simplest form?
Answers
The required value of y for the unit circle is: 2/3
How to find the point on the unit circle ?The circle is defined as the locus of a point whose distance from a fixed point is constant i.e center (h, k).
The equation of the circle is given by:
(x - h)² + (y - k)² = r²
where:
h, k is the coordinate of the center of the circle on coordinate plane.
r is the radius of the circle.
Here,
Equation of the unit circle is given as,
x² + y² = 1
Now substitute the given value in the equation,
5/9 + y² = 1
y² = 1 - 5/9
y² = 4/ 9
y = √(4/9)
y = 2/3
Thus, the required value of y for the unit circle is 2/3

Carol, Jada, and Brian were riding their bikes to the library after school. The library is 12 1/2 miles from school. Carol rides her bile 2 1/2 miles every five minutes. Jaylen rides her bike 5 3/4 miles every 12 minutes. Brian rides his bike 1 1/4 miles every 2 5/8 minutes. If they all leave school at the same exact time and follow the same exact path to the library, which person will arrive at the library first?
Answers
Answer:
Carol will arrive first.
Step-by-step explanation:
Since everyone leaves at the exact time and exact same spot, the problem devolves into who has the greatest speed.
To calculate speed, we do distance over time
Carol can bike 2.5 miles in 5 min, so their speed is .5 miles per min.
Jaylen can bike 5.75 miles in 12 min, so their speed is .479 miles per min.
Brian can bike at 1.25 miles in 2.625, so their speed is .476 miles per min.
Distance to the library doesn't matter in the context of the problem.

The standard deviation is a. 0.099 cm. b. 0.045 cm. c. 0.024 cm d. 0.005 cm. e. 0.455 cm.
Answers
The standard deviation for the given data is c. 0.024 cm.
Let's calculate the standard deviation using the given data:
Diameters: 0.493, 0.534, 0.527, 0.511, 0.565, 0.559, 0.519, 0.562, 0.551, and 0.530.
Find the mean:
Mean = (0.493 + 0.534 + 0.527 + 0.511 + 0.565 + 0.559 + 0.519 + 0.562 + 0.551 + 0.530) / 10
Mean ≈ 0.5411 cm
Calculate the squared differences:
\((0.493 - 0.5411)^2, (0.534 - 0.5411)^2, (0.527 - 0.5411)^2, (0.511 - 0.5411)^2, (0.565 - 0.5411)^2, (0.559 - 0.5411)^2, (0.519 - 0.5411)^2, (0.562 - 0.5411)^2, (0.551 - 0.5411)^2, (0.530 - 0.5411)^2\)
Find the average of the squared differences:
Average = (sum of squared differences) / 10
Take the square root of the average to get the standard deviation.
By calculating the above steps, the standard deviation of the given data set is approximately 0.024 cm.
Therefore, the correct answer is c. 0.024 cm.

Show if 139 and 450 are equivalent under modulus 7 or not.
Answers
The equivalent under modulus 7 of 139 and 450 is not same. A modulus is the whole-number remainder in a division equation. It can be calculated using the modulo operation. It helps determine whether or not a given integer is odd or even. Therefore, we can solve this problem by utilizing the modulo function.
Modulus refers to the process of converting a decimal number into a whole number. It is used to determine if a number is even or odd by looking at the last digit. If the last digit is even, the number is even. If the last digit is odd, the number is odd. The remainder after division is the modulus.
The symbol for modulus is % .To see if 139 and 450 are equivalent under modulus 7 or not, we will do the following:
We'll convert 139 to its remainder under modulus 7 using the modulo function.
139 % 7 = 4
We'll convert 450 to its remainder under modulus 7 using the modulo function.
450 % 7 = 3
Now, since both remainders are not the same, we can say that 139 and 450 are not equivalent under modulus 7.

You are shopping for single-use cameras to hand out at a party. The daylight cameras cost $2.75 and the flash cameras cost$4.25. You must buy exactly 20 cameras and you want to spend between $65 and$75, inclusive. Write and solve a compound inequality for this situation. Then list all the solutions that involve whole numbers of cameras.
Answers
The compound inequality for the given situation is $2.75x + $4.25y ≥ $65 and $2.75x + $4.25y ≤ $75, where x represents the number of daylight cameras and y represents the number of flash cameras.
To solve this compound inequality, we need to find the values of x and y that satisfy both conditions. The inequality $2.75x + $4.25y ≥ $65 represents the lower bound, ensuring that the total cost of the cameras is at least $65. The inequality $2.75x + $4.25y ≤ $75 represents the upper bound, making sure that the total cost does not exceed $75.
To list the solutions involving whole numbers of cameras, we need to consider integer values for x and y. We can start by finding the values of x and y that satisfy the lower bound inequality and then check if they also satisfy the upper bound inequality. By trying different combinations, we can determine the possible solutions that meet these criteria.
After solving the compound inequality, we find that the solutions involving whole numbers of cameras are as follows:
(x, y) = (10, 10), (11, 8), (12, 6), (13, 4), (14, 2), (15, 0), (16, 0), (17, 0), (18, 0), (19, 0), (20, 0).
These solutions represent the combinations of daylight and flash cameras that fulfill the requirements of buying exactly 20 cameras and spending between $65 and $75.

A regression model for a consumption function shows how household consumption and GDP have historically been related. The numbers in brackets underneath are the standard errors of the regression model. The coefficient in front of GDP is called the marginal propensity to consume, or MPC, because it is how much consumption goes up when GDP goes up by one unit. C=205 + 0.7 GDP (18) (0.051) A researcher finds that the marginal propensity to consume changes if she adds the % change in a stock market index as a variable. C=193 + 0.65 GDP + 0.08 (% change in stock price) (14) (0.12) (0.01) What is predicted consumption if GDP is 200 and if the share market falls by 20% ? (you do not have to worry about any effects of multicollinearity) 321.4 322.98 193 393
Answers
To find the predicted consumption, we can plug the given values into the regression equation:
C = 193 + 0.65 GDP + 0.08 (% change in stock price)
Given:
GDP = 200
% change in stock price = -20% (or -0.2)
Substituting the values:
C = 193 + 0.65 * 200 + 0.08 * (-0.2)
C = 193 + 130 - 0.016
C = 322.984
Rounding to two decimal places, the predicted consumption, when GDP is 200 and the share market falls by 20%, is approximately 322.98.
