Answer:

Step-by-step explanation:

This is similar to the other question. First, find the area of the outer rectangle. 12×9=108.

The inner rectangle: 2.5×8=20.

Then you subtract: 108-20

That would get 88

Answer:

Step-by-step explanation:

Note that (x^a)^b = x^ab.

Thus, (x^2/3)^4/5 = x^(2/3 * 4/5) = x^(8/15)

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. A rocket is launched from atop a

umka2103 [35]

When it hits the ground, then h=0
find the xintercept or in this case the tintercepts
c=76
v=135

h=-16t^2+135t+76
use quadratic formula

ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$

a=-16
b=135
c=76

x= $\frac{-135+/- \sqrt{135^2-4(-16)(76)} }{2(-16)}$
x= $\frac{-135+/- \sqrt{18225+4864} }{-32}$
x= $\frac{-135+/- \sqrt{23089} }{-32}$
aprox
x=-0.5297 or 8.967
exclude the negative root since you can't have negative time

means that it takes 8.97 seconds to hit the ground

Answer:

b. (2,0)

Step-by-step explanation:

To find which ordered pair is a solution, we have to replace then into the equation, and the result has to be an identity, that is, 0 = 0.

Equation:

$y = -5x + 10$
