If we take 140 to be the 100%, what is 35 off of it in percentage anyway?
Answer: Um ok? What are the measurements of the original batches...
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given
f(x) = x² + x + 1
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² + x
x² + 2(
)x +
-
+ 1
= (x +
)² +
→ C
Average rate of change = (f(29) - f(15))/(29 - 15) = (87 - 45)/14 = 42/14 = 3m/s^2
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
