Find the center and radius of the circle with equation (x+3)^2+(3+ 1)^2= 9. Then graph the circle.

Ymorist [56]

Answer:

See graph

$(x +3)^{2}$ + $(y + 1)^{2}$ = 9

(-3 , -1) is the center.

$\sqrt{9}$ = 3 = radius

Step-by-step explanation:

$(x - h)^{2} + (y - k)^{2} = r^{2}$

center (h,k)

radius = r

Calculate dy/dx when y = (x2 + 2)e 4x as the derivative of a product, letting u = x2 + 2 and v = e4x . Which of the following is

Vera_Pavlovna [14]

Answer:

D. du/dx = 2x

Step-by-step explanation:

Given to find dy/dx where;

$y=(x^{2} +2)e^4^x$

Then when you let;

u=x²+2 and

$v=e^{4x}$

Then

In u=x²+2 du/dx = 2x------------------------step 1

In e^4x, dv/dx = e^4x * d/dx (4x)

=e^4x *4 = 4e^4x------------------------------------step 2

Write a formula for the given measure. Let A represent the area in square feet, and h represent the height in feet. Identify whi

german

Answer:

So, the area of a trapezoid is A=9h in square feet.

Step-by-step explanation:

We know that a h represent the height in feet. We have that the base lengths of 7 feet and 11 feet. So,

$b_1=7\\\\b_2=11\\$

We calculate the area in square feet, where A represent the area.

We have the formula for the area of a trapezoid:

$\boxed{A=\frac{b_1+b_2}{2}\cdot h}$

Therefore, we get:

$A=\frac{b_1+b_2}{2}\cdot h\\\\A=\frac{7+11}{2}\cdot h\\\\A=9h$

So, the area of a trapezoid is A=9h in square feet.
