The measures of the other two angles are 20 and 30.

$180 - 130 = 50$

$2 + 3 = 5$

$50 \div 5 = 10$

$10 \times 2 : \: 10 \times 3$

$20 \: : \: 30$

A model rocket launched directly upward at a speed of 16 meters per second from a helght of 2 meters . The f(t) = - 4.9t ^ 2 + 1

Anton [14]

Answer:

f(t) = 15.06 m

Step-by-step explanation:

The relationship between the height of the rocket and the time after launch, t. In seconds is given by :

$f(t) = - 4.9t ^ 2 + 16t + 2$

We need to find the maximum height the rocket will reach the ground.

When it reaches the ground,

f(t) = 0

So,

Maximum height,

f'(t) = 0

$-9.8t+16=0\\\\t=\dfrac{16}{9.8}\\\\t=1.63\ s$

Put t = 1.63 in equation (1).

$f(1.63) = - 4.9\times (1.63 ^ 2) + 16(1.63) + 2\\\\=15.06\ m$

So, the maximum height of the rocket is 15.06 m.

Pls help :))))))))) uhhhhhhhhh

The answers are 3 and -13

You need to plug 3 and -5 into x

By doing this, you get :

12 - 3^2 and

12 - (-5)^2

those expressions equal

12 - 9

12 - 25

So you get

-13

Determine the quotient of 1 and 2 over 3 divided by 4 over 5 . (2 points)

saw5 [17]

Answer:

2 and 1 over 12

Step-by-step explanation:

$1 \frac{2}{3} \div \frac{4}{5} \\ \\ = \frac{1 \times 3 + 2}{3} \div \frac{4}{5} \\ \\ = \frac{5}{3} \times \frac{5}{4} \\ \\ = \frac{25}{12} \\ \\ = 2 \frac{1}{12} \\$
