Answer:
All speed from 0 mi/h and 11 mi/h were reached because the initial and final speed was 0 mi/h the speed of 10 mi/hr was reached at least twice in the race.
Step-by-step explanation:
Given,
Total distance covered = 6.2 miles,
Time taken = 34 minutes = hours
( 1 hour = 60 minutes )
Since,
Thus, the speed of the runner =
= 10.9411764706
≈ 11 miles per hour
Thus, the average speed of the runner is 11 miles per hour ( approx )
By MVT,
The speed was exactly 10 mi/hr at least twice in the race.
By intermediate value theorem,
All speed from 0 mi/h and 11 mi/h were reached because the initial and final speed was 0 mi/h the speed of 10 mi/hr was reached at least twice in the race.
Answer:
Step-by-step explanation:
tan x = ( sin x ) / ( cos x )
tan²x + 1 = sec²x
sec x = ± √(tan²x + 1)
sec x = 1 / cos x
~~~~~~~~~~~~
tan x = 4 and sin x < 0
cos x - ?
<u><em>If tan x > 0 and sin x < 0 ⇒ cos x < 0</em></u>
sec²x = 16 + 1 = 17 ⇒ cos²x =
cos x = -
Answer:
125°
Step-by-step explanation:
Supplementary angles sum to 180°
let one angle be x then the larger angle is x + 70, thus
x + x + 7 0 = 180
2x + 70 = 180 ( subtract 70 from both sides )
2x = 110 ( divide both sides by 2 )
x = 55
Hence
larger angle = x + 70 = 55 + 70 = 125°
12p+24t bc first you have to add 3+2 then multiply it by each term
Answer: x = - 1/3 y^2 + 1/3
