Average rate of change of the function: 
Step-by-step explanation:
The average rate of change of a function f(x) can be calculated as:
where:
are the x-values of the interval taken into account to evaluate the rate of change of the function
are the values of the function at those points
In this problem, we have:
The function is 
, so
So, the average rate of change in this interval is:

Answer: 1/2+1/10=3/5
(8x4)-(7x3)= 11
Step-by-step explanation:
53 is not a perfect square and whereby not using a calculator, 53 is between the perfect squares of 49 and 64. Hence the answer should be between 7 and 8. since 53 is closer to 49, then the answer should be close to 7. use a calculator to verify
Answer:
45 degrees
Step-by-step explanation:
We can solve for the y-intercepts of both f(x) and h(x) by plugging in 0 as x. f(0) = -6(0)-3 = -3
h(0) = -2cos(pi)-1 = -2(-1)-1 = 1
So the y-intercept of f(x) is -3 and of h(x) is 1. We can then conclude that h(x) has a greater y-intercept than f(x) because 1>-3.
