Answer:

Answer: d) -310pi

Step-by-step explanation:

Instantaneous Rate of Change

Is the change in the rate of change of a function at a particular instant. It's the same as the derivative value at a specific point.

The surface area of a cylinder of radius r and height h is:

[tex]A=2\pi r^2+2\pi r h[/tex]

We need to calculate the rate of change of the surface area of the cylinder at a specific moment where:

The radius is r=8 mm

The height is h=3 mm

The radius changes at r'=-9 mm/hr

The height changes at h'=+2 mm/hr

Find the derivative of A with respect to time:

[tex]A'=2\pi (r^2)'+2\pi (r h)'[/tex]

[tex]A'=2\pi 2rr'+2\pi (r' h+rh')[/tex]

Substituting the values:

[tex]A'=2\pi 2(8)(-9)+2\pi ((-9) (3)+(8)(2))[/tex]

Calculating:

[tex]A'=-288\pi +2\pi (-27+16)[/tex]

[tex]A'=-288\pi +2\pi (-11)[/tex]

[tex]A'=-288\pi -22\pi[/tex]

[tex]A'=-310\pi[/tex]

Answer: d) -310pi

8/20 + 5/20 = 13/20

Answer:

150 boys were enrolled in 2012

Step-by-step explanation:

Let the number of boys enrolled in 2012 be x

Let the number of girls enrolled in 2012 be x + 200

Ratio of boys to girls in 2012 enrollment = 3/7

Now;

3/7 = x/x + 200

7x = 3(x + 200)

7x = 3x + 600

7x - 3x = 600

4x = 600

x = 600/4

x = 150 boys

Hence, 150 boys were enrolled in 2012

Answer:

(-1, 3), (-5, -5), and (1, 2)

Step-by-step explanation:

To make this easier to solve, simplify the inequality:

12x - 3y < 12

= -3y < -12x + 12 (subtract 12x)

= 3y > 12x - 12 (multiply by -1, switch the inequality because it was a multiplication by a negative number)

= y > 4x - 4 (divide by 3)

Now, just go through each point and see if they are correct after you plug them into the inequality and solve:

(-1, 3): 3 > -8? yes

(-5, -5): -5 > -24? yes

(0, -4): -4 > -4? no

(1, 2): 2 > 0? yes

(4, 4): 4 > 12? no

(3, 8): 8 > 8? no

In conclusion, the points (-1, 3), (-5, -5), and (1, 2) fit the inequality.

Adriana needs to send 232 invitations to her family and friends for her party.

There are 12 invitations in a box.

We need to find how many boxes will Adriana needs to order so that everyone receives an invitation. Let there are x boxes. It can be calculated as :

[tex]x=\dfrac{232}{12}\\\\x=19.34[/tex]

or

x = 19

So, she will need approx 19 boxes.

Answer:

Donald Trump is a racist misogynist who only thinks of himself. He doesn't care about anyone else and even s*xualized his own daughter. Anyone who supports him is either just as bad as he is, a r*cist and a r*pist who only cares about their own well fare, or you are an ignorant full proof idiot human. You believe the lies that democrats will take away your rights (this is false) and you actually think Donald Trump can help America. Educate yourself and learn that Trump is one of the worst humans alive and you are not too far off yourself if you support him. Being a trump supporter is one of the most insulting things to the human race.  

Step-by-step explanation:

I would normally myself a republican, though I am very towards the middle, and I still would vote for Biden. Even if I do not like him we have to settle and do what is best for the so many people hurting because of Trump's leadership. Thank you very much. :(

Answer:

Let's identify what we know and what we are looking for. To start off, the question states that there is a flat rate of 500. This is the y intercept, because you start off with 500. It also states that it charges a fee of 50 per hour, which is your slope. So what we have now is y=50x+500. We know that A is asking how much it will be for 20 hours. We simply plug 20 into x, so we do y=50(20)+500 which gives 1500. For C, we repeat the same step and just plug in 50.

Answer:

x= 175°

Step-by-step explanation:

angles in a triangle add up to 180 degrees

85 + 90 = 175

180 - 175 = 5 (the missing angle not x)

angles on a straight line add up to 180 degrees

180 -  5 =175

Answer:

A = 25π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( where r is the radius )

Here diameter = 10, thus r = 10 ÷ 2 = 5, then

A = π × 5² = 25π cm²

Answer:

You are given two points, (0,6) and (3,-3), so use the two-point formula for the equation of a line:

y - y1 = ( (y2 - y1) / (x2 - x1) ) (x - x1)

y - 6 = ( -9 / 3 ) (x - 0)

y - 6 = -3x

y = -3x + 6 This is: y = mx+b

Step-by-step explanation:

The linear function with the values f(0) = 5 and f(-3) = 6 is [tex]y=\frac{-1}{3}x+5[/tex]

The given functions are:

f(0)  =  5

f(-3)  =  6

That is, x₁ = 0,  y₁ = 5, x₂ = -3, y₂ = 6

The slope of the linear function is calculated as:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{6-5}{-3-0} \\\\m=\frac{-1}{3}[/tex]

The equation of a line is given as:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-5=\frac{-1}{3}(x-0)\\\\y-5= \frac{-1}{3}x\\\\y=\frac{-1}{3}x+5[/tex]

The linear function with the values f(0) = 5 and f(-3) = 6 is [tex]y=\frac{-1}{3}x+5[/tex]

Answer: Sara bought billboards with 4 lines for $20 (the quantity is 7)

We have to take the total cost (t) and divide that buy the 6 lines billboards and the 4 line billboards.

So, let's divide $140 by 20 and 30 (the cost for each type of billboard).

$140 ÷ 30 = 4.6

This can not be the answer because Sara bought 7 billboards, not 4.6

$140 ÷ 20 = 7

So, the answer is Sara bought billboards with 4 lines for $20.

Hope this helps you!

Answer:

Domain - [0, 4]

Range - [100, 400]

Step-by-step explanation:

Function representing the amount of money 'y' and hours of babysitting 'x' is,

y = 10x + 100

a). The dependent variable is,

   Amount of money in the bank account.

    The independent variable is,

   Number of hours of babysitting

b). x       0        1         2         3        4

    y      100    110      120     130     140

   Since, x values of a function represent the domain and y-values represent the range,

   Domain - [0, 4]

   Range - [100, 140]
