The answer is 55. First, you take 25% and turn it into a decimal (0.25). Then, multiply 220 by 0.25 (55). Since it’s only asking for the documentaries, the answer is just 55.
Y = 1.50x + 4......x = 7
y = 1.50(7) + 4
y = 10.50 + 4
y = 14.50 <===
Answer:
spinner 2 is 14
Step-by-step explanation:
7+3=10
10+4=13
For the first interval (-1, 2), f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.
<h3>
Over which interval the rate of change is zero?</h3>
For a function f(x) we define the average rate of change over the interval (a, b) is defined as:
R = (f(b) - f(a))/(b - a)
Here the function is:
f(x) = x^2 - x -1
And the rate of change will be zero on an interval (a, b) if and only if:
f(b) = f(a).
Notice that the first interval is (-1, 2)
f(-1) = (-1)^2 - (-1) - 1 = 1 + 1 - 1 = 1
f(2) = 2^2 - 2 - 1 = 4 - 2 - 1 =1
Then f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.
