I WILL MARK BRAINIEST<br> PLEASE HELP ASAP ITS DUE

Daniel [21]

Answer:

A) 1 : 4

B) 1 : 2

C) Base of M = 10 units

Step-by-step explanation:

The ratio of the area of triangle M to triangle N

$\frac {40}{160}= \frac{1}{4} = 1 : 4$

The ratio of the side lengths of triangle M to triangle N

$\sqrt{ \frac {40}{160}} = \sqrt{\frac{1}{4}} \\\\={\frac{1}{2}} \\\\=1 : 2$

C) Let the base of triangle M be b units.

$\sqrt{ \frac {40}{160}} = \frac{b}{20}\\\\\frac{1}{2}= \frac{b}{20}\\\\2b = 20\\\\b = \frac{20}{2} \\\\b = 10$

A ball is thrown in the air from a ledge. Its height in feet is represented by f16(2-5x - 6), where x is the number of seconds s

Assoli18 [71]

Height in feet is represented by $f(x) = -16(x^2-5x-6)$

The height of the ball is 0 feet when it hits the ground.

So we replace height f(x) by 0 and solve for x to find the time taken to reach the ground

$f(x) = -16(x^2-5x-6)$

$0= -16(x^2-5x-6)$ ( divide by -16 on both sides)

$0=(x^2-5x-6)$

Now factor it

(x-6)(x+1) =0

x-6 =0 and x+1=0

x=6 and x=-1

Time cannot be negative so we ignore -1

x = 6 seconds

It will take 6 seconds for the ball to reach the ground.
