Graph the equation. (x + 3)2 + (y + 2)2 = 16
Sati [7]

okay well first you should put it in slope-intercept form aka y = mx + b

but you have simplify everything first

2(x + 3) + 2(y + 2) = 16

2x + 3 + 2y + 4 = 16

2x + 2y + 7 = 16

              -7    -7  

2x + 2y = 9

-2x          -2x

2y = -2x + 9

/2         /2

y = -x + 4.5

so now in a graph it should look like this:

Suppose Neil Armstrong decided to throw a golf ball into the air while he was standing on the
lawyer [7]

Answer:

At 7 seconds the instantaneous rate of change of the function s(t) with time which is the velocity is -11.18 m/s

Step-by-step explanation:

The given information on the height can be written as follows;

s(t) = -2.72·t² + 26.9·t + 6

Where;

s = The height (displacement) of the golf ball

t = The time taken during the motion of the golf ball

The velocity is found by finding the derivative of the displacement s as follows;

v = d(s(t))/dt = d(-2.72·t² + 26.9·t + 6)/dt = 2×(-2.72)×t + 26.9

When t = 7, v = 2×(-2.72)×7 + 26.9 = -11.18 m/s

Therefore the ball is coming down with 11.18 m/s speed at 7 seconds.

FinnZ [79.3K]

Answer:

Option D.The ratio of the radius of a circle to its circumference

Step-by-step explanation:

<em>Verify each statement</em>

A) The ratio of the circumference of a circle to its diameter

The statement is True

Because

C=\pi D

so

\pi=C/D

B) Approximated to be 3.14

The statement is True

Because \pi=3.14159265...

C) Approximated to be 22/7

The statement is True

Because

\frac{22}{7}=3.1423

D) The ratio of the radius of a circle to its circumference

The statement is not True

Because

\frac{r}{2\pi r}=\frac{1}{2\pi}
