PLEASE HELP WILL GIVE MANY POINTS QUICK PLEASE

Answer:

v = 33.95m/s

Step-by-step explanation:

Given

h = 58.8m --- height

u = 0 --- initial velocity

g = 9.8m/s^2 --- acceleration

Required

The velocity when he hit the water

The velocity is then calculated using:

v^2 = u^2 + 2gh

This gives:

v^2 = 0^2 + 2*9.8 * 58.8

v^2 = 0 + 1152.48

v^2 = 1152.48

Solve for v

v = \sqrt{1152.48

v = 33.95m/s

Use the discriminant to describe the roots of each equation. Then select the best description. 2x2 + 7x + 6 = 0 double root real
arlik [135]

So the equation to find the discriminant is √(b^2 - 4ac), with a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation above, we can solve for it as such:

\sqrt{7^2-4*2*6}\\ \sqrt{49-48}\\ \sqrt{1}\\ 1

Since the discriminant is greater than zero and a perfect square, this means that there are 2 real, rational solutions to this polynomial.

The number of social media post of Noami has a greater spread when compared to that of Amir.

<h3 /><h3>What is the range and intequartile range of the social media posts?</h3>

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

  • The range of Amir's social media posts = 19 - 15 = 4
  • The range of Noami's social media posts = 10 - 0 = 10

The inter quartile range is the difference between the third quartile and the first quartile of a data set.

IQR = Q3 - Q1

The IQR of Amir's social media posts: 7

The IQR of  Naomi's social media posts = 10
