Answer:
See below.
Step-by-step explanation:
Formula: A = πr²
Since the radius is 4, we fill in the formula with the radius.
A = (3.14)4²
A = (3.14)16
A = 50.24

Answer:
Step-by-step explanation:
<u>Given</u>
- x = {5, 6, 7, 8, 9} and
- y = {33, 39, 45, 51, 57}
<u>The equation in slope- intercept form:</u>
<u>Using two pairs of coordinates (5, 33), (6, 39), we will find the slope:</u>
- m = (39 - 33)/(6 - 5) = 6/1 = 6
<u>Using one point (5, 33) to find the y-intercept:</u>
- 33 = 6*5 + b ⇒ b = 33 - 30 ⇒ b = 3
<u>The equation is:</u>
Correct option is B
It took both 2.5 hours to be 110 miles apart
Speed is the ratio of distance travelled to time taken. Speed is given by:
Speed = distance / time
Since both steamers is travelling at 22 mph. therefore they cover the same distance at the same time. For them to be 110 miles apart, they need to each have covered 55 miles in the opposite direction
22 = 55/time
time = 2.5 hours
Therefore after 2.5 hours they would have covered 55 miles each therefore being 110 miles apart.
