Answer:
56 cm
Step-by-step explanation:
By using a^2 + b^2 = c^2, you can determine that the slanted line of the trapezoid is ~11.6, which rounds to 12 cm.
12 + 14 + 24 + 6 = 56
2(cos2x - sin2x)
Step-by-step explanation:
Y = sin2x + cos2x
Differentiate wrt x
dy/dx = cos2x . 2 - sin2x . 2
= 2(cos2x - sin2x)
Answer:
i think it is g(x)=x^3/8 -1
Step-by-step explanation:
Answer:
She is going at the rate of 4.5 feet per second.
Step-by-step explanation:
Given:
The rate of walking is 90 yards per minute.
Now, to find the rate in feet per second.
1 yard = 3 foot.
1 minute = 60 seconds.
So, first we find the rate of walking per second in yard = 
Therefore by dividing we get =
Now, we find the rate of walking per second in feet = 
So, by multiplying we get = 
Therefore, she is going at the rate of 4.5 feet per second.
