If the diver in item 2 leaves the board with an initial upward speed of 2.00 m/s, find the diver's speed when striking the water

Taya2010 [7]

Answer:

$v_f=9.0774m/s$

Step-by-step explanation:

Let's assume

initial velocity =vi

final velocity=vf

initial height =hi

final height =hf

acceleration due to gravity =g

we can use formula

$\frac{1}{2}v_i^2+gh_i= \frac{1}{2}v_f^2+gh_f$

we are given

$v_i=2m/s$

$h_i=2\times 2=4$

$h_f=0$

$g=9.8m/s^2$

now, we can plug values

$\frac{1}{2}(2)^2+(9.8)(4)= \frac{1}{2}v_f^2+(9.8)(0)$

now, we can solve for vf

$\frac{1}{2}(2)^2+(9.8)(4)= \frac{1}{2}v_f^2$

we get

$v_f=9.0774m/s$

A quadratic function is shown. f(x) = -x^2+7x-12 one factor of this function is (x-4). What is the other factor of the quadratic

Alexus [3.1K]

Answer:

The other term is<u> (x-3)</u>

Step-by-step explanation:

The quadratic function is:

$f(x)=-x^{2}+7x-12$

Factoring this function we will have:

$f(x)=-(x-4)(x-3)$

Therefore, the other term is<u> (x-3).</u>

I hope it helps you!

What fraction would you use to find 66.66% of 72?

Soloha48 [4]

I don't think you use a fraction. You multiply .6666 by 72 which equals 47.9952 or rounded 48. :)
