Step-by-step explanation:
Answer:
distance covered in 5 seconds
= 1.4283 *10^10 feet
Step-by-step explanation:
A racecar is traveling at a constant speed of 150 miles per hour.
One mile = 5280 feet
150 miles= 5290*150
150 miles= 793500 feet
A racecar is traveling at a constant speed of 793500 feet per hour.
Converting 793500 feet per hour to feet per seconds .
793500 feet per hour
= 793500*60*60 feet per seconds
=2856600000 feet per second
In 5 seconds , distance covered
= 2856600000 *5
distance covered in 5 seconds
= 1.4283 *10^10 feet
Answer:
126 degrees
Step-by-step explanation:
Angle 4 is supplemnetary to angle 3..which means both of their angles add up to 180 degrees
We can take the angle of 3 whihc is 54 degrees and subtract that from 180 to determine angle 4:
180 - 54 = 126
Angle 4 is 126 degrees
Answer: 2x(16x^2−7)
Step-by-step explanation:
Answer:
r = 7
Step-by-step explanation:
60 = -24 + 12r
<u>+24 +24</u>
84 = 12r
84 ÷ 12 = r
7 = r
Check:
60 = -24 + 12r
-24 + 12(7)
-24 + 84 = 60
