10s^2-15s+20 is the answer according to distributive property
Answer:
(0, 1)
(7.1, 0.49)
Step-by-step explanation:
The graph of the function is attached below.
We have an exponential function:

And we have a quadratic function:

To find the solution to:

we must look in the graph for the values of x for which both curves are intercepted, these values are:

Then the solution are the following ordered pairs:
(0, 1)
(7.1, 0.49)
Your answer for this is C
The measurement of ∠1 is half of the central angle's length 120
120/2 = 60
60° is your answer
Reason: This is because an inscribed angle is half of the arc length.
A central angle is the same measurement as the arc length.
hope this helps
