**Answer:**

7y+21

**Step-by-step explanation:**

7(y+4)-7

=7y+28-7

=7y+21

Ok so

0.5%=0.005

0.005x=8

x=8/0.005

x=1600

8 is 0.5% of 1600

Hope this helps

If u still don't understand plz message me

If u understand plz brainlest me

If you continue with the same formula with a different problem then you will get it correct

Thank you!

**Answer:**

**Step-by-step explanation:**

The figure is made up of a rectangle and two semicircles.

We find the area of the rectangle using the formula;

We find the area of one of the semicircles and multiply by 2;

The area of the semicircles

We substitute and to obtain;

The area of the figure is

To the nearest tenth we have;

The correct answer is A

A is on the graph. When you plug in 3 in for x you get -4

B is not. When 1 is plugged in you do notnget 4

**Answer:**

y_c = 2 + 10*x

**Step-by-step explanation:**

**Given:**

y'' = 0

**Find:**

- The solution to ODE such that y(0) = 2, y'(0) = 10

**Solution:**

- Assuming a solution y = Ce^(mt)

So, y' = C*me^(mt)

y'' = C*m^2e^(mt)

- Back substitute into given ODE, we get:

y'' = C*m^2e^(mt) = 0

e^(mt) can not be equal to zero

- Hence, m^2 = 0

m = 0 , 0 - (repeated roots)

- The complimentary function for repeated roots is:

y_c = (C1 + C2*x)*e^(m*t)

** y_c = C1 + C2*x **

- Evaluate @ y(0) = 2

2 = C1 + C2*0

C1 = 2

-Evaluate @ y'(0) = 10

y'(t) = C2 = 10

Hence, ** y_c = 2 + 10*x **
