Write the equation of the line that passes through the points (7, -3) and (7, 0).

Akimi4 [234]

Answer:

x = 7

Step-by-step explanation:

Since the x- coordinates of the 2 points are equal, both 7 , then the line is vertical with equation

x = c

where c is the value of the x- coordinates the line passes through, then

x = 7 ← equation of line

Find the measure of the missing angles.

ryzh [129]

Answer:

d = 69° , e = 32° , f = 79°

Step-by-step explanation:

d and 69° are vertically opposite angles and are congruent , so

d = 69°

e and 32° are vertically opposite angles and are congruent , so

e = 32°

69° , e , f lie on a straight line and sum to 180° , that is

69° + 32° + f = 180°

101° + f = 180° ( subtract 101° from both sides )

f = 79°

Answer:

7.0 m/s

Step-by-step explanation:

We can solve this using the 2 kinematic equations and you can use either:

$Vf=Vi+at\\\\vf^{2}=vi^{2}+2ad$

So let's use the first one.

Vi = initial velocity

Vf = final velocity

a = acceleration due to gravity (constant 9.8m/s²)

t = time

The marble is dropped so this means that it is in free fall. The initial velocity is always 0m/s.

We are given then the following:

d = 2.5m

t = 0.71s

Vi = 0 m/s

a = 9.8m/s²

So we plug in the values we know and solve:

$Vf = Vi + at\\\\Vf = 0 m/s + (9.8m/s^{2})(0.71s)\\Vf = 6.958m/s \cong 7.0m/s$
