The angle is and acute angle.
Acute: Anything under 90 Degrees
Right: 90 Degrees
Obtuse: Anything Above 90 Degrees
Speed = Distance/Time
Runner Speed = 200/21.3 = 9.4 m/s
Swimmer Speed = 1.8 m/s
9.4 - 1.8 = 7.6 m/s
C
Equation in point-slope form is 
Option C is correct.
Step-by-step explanation:
We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5
The formula used for point-slope form is:

We are given slope m = 4/5
Point (-7,9) where x₁ = -7 and y₁ = 9
Putting values in the formula:

So, equation in point-slope form is 
Option C is correct.

Answer:
here you go
Step-by-step explanation:
no of times he failed = -3
points he losed = -3 x 4 = -12
no of times he need to hit the target to get 48 points = 6x
<u>equation</u>
<u>-12 + 6x = 48</u>
<u>6x = 60 </u>
<u>x = 10</u>
no of points he will gain = 10 x 6 = 60
