Answer:

m < DBC = 51

Step-by-step explanation:

Looking at the picture, we know <ABD and <DBC make up <ABC. Knowing this, we can set up an equation like so, plug in the known values, and solve to find m<DBC:

$m$

PLEASE HELP!!! I WILL GIVE BRAINY!!!

11111nata11111 [884]

The first one is 4/3

We can solve by,

${x}^{2} \times 180 = 320$

$x = \frac{4}{3}$

${ \frac{4}{3} }^{2} \times 180 = 320 = true$

~~

The second one is 35.

Idk how to explain...

~~

The third one is a 6 - gon therefore cannot be C or D.

I'd say the third one is A., it looks like it's caving in.

One day at football practice, Darrell, the kicker, punted the ball so that its height in feet above the ground was given by the

nika2105 [10]

When the football is 81 feet high, it will be √ 3 / 8 seconds

<h3>Function</h3>

Function relates input to output. Therefore,

h(t) = - 16t² + 75

Therefore,

t = number of seconds

h(t) = - 16t² + 75

h(t) = 81 ft

Therefore,

81 = - 16t² + 75

- 16t² = 81 - 75

- 16t² = 6

divide both sides by -16

t² = 6 / -16

t² = - 3 / 8

square root both sides

t = √ 3 / 8 seconds
