f a football player passes a football from 4 feet off the ground with an initial velocity of 36 feet per second, how long will i

t take the football to hit the ground? Use the equation h = −16t2 + 36t + 4

When it hits the ground h = 0 so we have

-16t^2 + 36t + 4 = 0

t = 2.36 seconds to nearest hundredth.

PLEASE HElp asap <br> Solve for x.<br> x = [?]<br> X + 19<br> 7x + 9

Bess [88]

X + 19 + 7x + 9 = 180
8x + 28 = 180
8x = 180 - 28
8x = 152
X = 152 : 8
X = 19

X,y and z are three consecutive even numbers if y^2 - 2 = 2x + 5Z find x,y and z

Rama09 [41]

Answer:

6, 8, 10

Step-by-step explanation:

x y and z are three consecutive even numbers

it means that you can write y = x + 2

and z = y + 2 = x + 4

so

$y^2-2=2x+5z\\ (x+2)^2-2=2x+5(x+4)\\x^2+4x+4-2=2x+5x+20$

$x^2+4x+2=7x+20\\x^2+4x+2-7x-20=0\\x^2-3x-18=0\\(x+3)(x-6)=0(x=-3\ or \ x=6)$

so the solutions are

x = 6

y = 8

x = 10
