Answer:
Step-by-step explanation:
<u>Formula is given</u>
<u>If C = 15 yd, π = 3.14, then r is</u>
- C = 2πr
- r = C/2π
- r = 15/(2*3.14) = 2.39 yd rounded to the nearest 100th
Parallel to the y axis...that would mean that it is a vertical line.
The equation would be : x = 4 and it would have an undefined slope
Answer:
15
Step-by-step explanation:
n + 6
for
n = 9
then:
9 + 6 = 15
I think a is (8,-8)
B) (0,8)
The given
equation in this case is:
<span> y = -16 t^2 + 400</span>
We can see
that the slope of the equation is negative (-16) which means that the position
of Kay is on the positive y-axis , while the bottom of the river is in the
origin. This is supported by taking t = 0, the initial y becomes y = 400.
Therefore the position of Kay now is at (0, 400).
So to find
for the time when the camera hits the water, then y must be zero (t, 0) so we
have to find for t in this case.
When y = 0
0 = -16 t^2
+ 400
16 t^2 = 400
t^2 = 25
t = 5 s
<span>Therefore it
takes 5 seconds for the camera to hit the water and for Kay to see a splash.</span>
