The actual speed (along the road) of the red car is 8.37 feet per second
To solve this problem
Let's call the distance between the police car and the red car "x" at time t. Then, we know that:
x^2 = 40^2 + (140 - vt)^2
Where
v is the velocity of the red car (in feet per second) t is timeWe are given that dx/dt (the rate at which x is decreasing) is -85 ft/s, so:
d/dt [x^2] = d/dt [40^2 + (140 - vt)^2]
2x(dx/dt) = 0 - 2v(140 - vt)
Substituting dx/dt = -85 and solving for v, we get:
2x(−85) = −2v(140−vt)
−170x = −280v + 2v^2t
v^2t = 140v - (85/2)x
Now, we can differentiate the equation x^2 = 40^2 + (140 - vt)^2 with respect to time to get:
2x(dx/dt) = 2(140 - vt)(-v)
Substituting dx/dt = -85 and solving for x, we get:
-170x = -2v(140 - vt)
x = (140v - vt^2)/85
Substituting this expression for x into the equation we derived earlier, we get:
v^2t = 140v - (85/2)((140v - vt^2)/85)
v^2t = 140v - 70(2v - t^2)
v^2t = 140v - 140v + 70t^2
v^2t = 70t^2
v = sqrt(70t^2)/t = sqrt(70) = 8.37 ft/s (rounded to two decimal places)
Therefore, the actual speed (along the road) of the red car is 8.37 feet per second

Select the property of equality used to arrive at the conclusion. If x + 8 = 10, then x = 2. the multiplication property of equality the subtraction property of equality the division property of equality
The correct option- B. the subtraction property of equality is used to arrive at the conclusion. If x + 8 = 10, then x = 2.
Explain about the subtraction property of equality :According to the equality's feature of subtraction, equality is unaffected when the same amount is subtracted from both sides of an equation.
If the exact same number or value is removed from both sides of an equation, the difference that results on both sides is also equal. Equal deductions from both sides of such an inequality will decrease the values on each side but have no effect on the inequality's truth value. In other words, the left side of a inequality will continue to be smaller than the right in a "less than" statement.Given data:
x + 8 = 10
To find the value of x, subtract 8 from both sides:
x + 8 -8 = 10 - 8
x = 2
Thus, the subtraction property of equality is used to arrive at the conclusion. If x + 8 = 10, then x = 2.

what is equation ?
In mathematics, an equation is a statement that two expressions are equal. An equation can contain variables, constants, and mathematical operations like addition, subtraction, multiplication, division, exponents, and roots.
In the given question,
We can start by finding out how long it takes Kylie to fill one 2-ounce container. To do this, we can set up a proportion:
75 containers / 50 minutes = 1 container / x minutes
Solving for x, we get:
x = (50 minutes) / (75/1) = 0.67 minutes per container
Now we can use this information to find how long it will take Kylie to fill 450 containers:
450 containers × 0.67 minutes per container = 301.5 minutes
So it will take Kylie 301.5 minutes to make the slime and fill up 450 containers. We can convert this to hours by dividing by 60:
301.5 minutes / 60 minutes per hour = 5.025 hours
Rounding to the nearest hour, we get 5 hours.
Therefore, the answer is (B) 5 hours.

If one flyer is 3.0 × 10-3 inches thick, how thick is a stack of 1.25 × 103 flyers
If one flyer is 3.0 × 10⁻³ inches thick, the stack of 1.25 × 10³ flyers has a thickness of 3.75 inches.
To find the thickness of a stack of flyers, we need to multiply the thickness of a single flyer by the number of flyers in the stack. In this case, the thickness of a single flyer is given as 3.0 × 10⁻³ inches, and the number of flyers in the stack is 1.25 × 10³.
So, the thickness of the stack can be calculated as:
Thickness of stack = Thickness of a single flyer x Number of flyers in the stack
Thickness of stack = 3.0 × 10⁻³ inches x 1.25 × 10³
Thickness of stack = (3.0 x 1.25) × (10⁻³ × 10³) inches
Thickness of stack = 3.75 inches

abc is dilated by a scale factor of 4 with a center of dilation at the origin to form a’b’c’ then a’b’c’ is dilated by a scale factor of 3 over 4 with a center of dilation at the origin to create a’’b’’c’’ what are the coordinates of a’’b’’c’’
The coordinates of the vertices of the triangle A''B''C'' after the two successive dilations are (3 times the x-coordinate and 3 times the y-coordinate of the original triangle's vertices).
To find the coordinates of the vertices of the dilated triangle A''B''C'' after two successive dilations, first with a scale factor of 4 and then with a scale factor of 3/4.
Firstly, Apply the first dilation with a scale factor of 4 to the original triangle ABC, with a center of dilation at the origin. This can be done by multiplying each coordinate of the original triangle by 4.
The coordinates of the dilated triangle A'B'C' after the first dilation would be;
A' = (4 × x-coordinate of A, 4 × y-coordinate of A)
B' = (4 × x-coordinate of B, 4 × y-coordinate of B)
C' = (4 × x-coordinate of C, 4 × y-coordinate of C)
Now, we apply the second dilation with a scale factor of 3/4 to the dilated triangle A'B'C', again with a center of dilation at the origin. This can be done by multiplying each coordinate of A'B'C' by 3/4.
The coordinates of the dilated triangle A''B''C'' after the second dilation would be;
A'' = ((3/4) × x-coordinate of A', (3/4) × y-coordinate of A')
B'' = ((3/4) × x-coordinate of B', (3/4) × y-coordinate of B')
C'' = ((3/4) × x-coordinate of C', (3/4) × y-coordinate of C')
Plugging in the values of A', B', C' obtained from the first dilation, we get;
A'' = ((3/4) × 4 × x-coordinate of A, (3/4) × 4 × y-coordinate of A)
B'' = ((3/4) × 4 × x-coordinate of B, (3/4) × 4 × y-coordinate of B)
C'' = ((3/4) × 4 × x-coordinate of C, (3/4) × 4 × y-coordinate of C)
Simplifying further, we get;
A'' = (3 × x-coordinate of A, 3 × y-coordinate of A)
B'' = (3 × x-coordinate of B, 3 × y-coordinate of B)
C'' = (3 × x-coordinate of C, 3 × y-coordinate of C)
Therefore, the coordinates of the vertices of the triangle A''B''C'' after the two successive dilations are (3 times the x-coordinate and 3 times the y-coordinate.

Choose any dataset (from any online resource). Describe any variable on the dataset where you can apply CLT for mean and CLT for proportions.
Here is a possible dataset with variables for which the central limit theorem could be applied:
A dataset of customer spending at different retail stores.
Variable for which CLT for mean could be applied:
Average monthly spending per customer. As the number of customers at each store increases, the sample mean spending will approach a normal distribution.
Variable for which CLT for proportions could be applied:
Proportion of customers who spend over $200 per month. Even with a small number of customers at each store, the proportion will be approximately normally distributed as the sample size increases due to the CLT for proportions.
The central limit theorem states that the sampling distribution of the sample mean and sample proportion will be normally distributed for large sample sizes, regardless of the original distribution. So these variables from the retail dataset would satisfy that condition. Please let me know if you would like any clarification or have a different dataset in mind. I can provide additional examples.

How many hours will it take for the number of bacteria to reach 3500?
Round your answer to the nearest tenth, and do not round any intermediate computations.
It will take 2.48 hours for the number of bacteria to reach 3500.
How many hours to reach 3500?In order to find number of hours to take for the number of bacteria to reach 3500, we can set the function equal to 3500 and solve for h.
The function given is P(h) = 2800e^(0.09h). So, plugging the values of 3500, we will get:
3500 = 2800e^(0.09h)
Dividing both sides by 2800, we get:
e^(0.09h) = 3500/2800
Taking the natural logarithm of both sides, we get:
0.09h = ln(3500/2800)
h = (ln(3500/2800))/0.09
h = 0.22314355131/0.09

The equation of the line is
Answer:
y = -x +3
Step-by-step explanation:
You want the slope-intercept equation of the line with the same intercept as -3y = -9 +3x, and the same slope as -2x -2y = -8.
Slope-intercept formThe slope-intercept form of the equation of a line is ...
y = mx +b . . . . . where m is the slope, and b is the y-intercept
For the given equations, we can put them in this form to find the desired parameters.
-3y = -9 +3x
y = -x +3 . . . . . . . . . . divide both sides by -3
We observe that the y-intercept is +3, which we will need for our answer.
The slope-intercept form of the second equation is ...
-2x -2y = -8
x + y = 4 . . . . . . . . . . divide by -2
y = -x +4 . . . . . . . . . . subtract x
We observe that the slope (coefficient of x) is -1, which we will need for our answer.
Desired equationWe want the equation of the line with slope -1 and y-intercept 3. It is ...
y = -x +3 . . . . . . . . . . same as the equation of the first line

Additional comment
The slope-intercept equation (green) is plotted using dots, so that you can see it is coincident with the line described by the first equation (red). Parallel lines have the same slope, so our desired line must be parallel to the blue line. (It is.)

In a certain video game, players can create environments and populate them with a variety of characters. One player creates a magical park in which the unicorn population triples each day. The starting unicorn population is 5. What will the unicorn population be after the 4th day?
Using the laws of multiplication, we can find that after the 4th day the unicorn population of the park is 405.
Define multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors.
In the question,
Let the unicorn population be = x.
Now as per the question,
It triples every day.
The function will be = 3x.
The starting unicorn population is 5.
After the 1st day it will get tripled and become 3 × 5 = 15.
After the 2nd day the unicorn population will be 3 × 15 = 45.
After the 3rd day, 3 × 45 = 135.
Finally, after the 4th day, the unicorn population will be = 3 × 135 = 405.
