Answer:
the car is traveling 60 miles per hour
Step-by-step explanation:
Since it is going 30 miles in half an hour, we just need to double both values to find the speed for an hour
30*2=60
1/2*2=1
60 miles per hour
hope this helps pls give crown <3

Step-by-step explanation: hope this helps u :)
Answer:
B
Step-by-step explanation:
started of with 0.004 and went up to 0.214 so
0.214-0.004= 0.210
Answer:
1. y=5-2x
2. -y=5-2x
3.
Step-by-step explanation:
1. 2x+y=5
y=5-2x
2. 2x-y=5
-y=5-2x
3. x+2y=5
2y=5-x

Hi there!
A.) Begin by verifying that both endpoints have the same y-value:
g(-1) = 2(-1)² - 4(-1) + 3
Simplify:
g(-1) = 2 + 4 + 3 = 9
g(2) = 2(2)² - 4(2) + 3 = 8 - 8 + 3 = 3
Since the endpoints are not the same, Rolle's theorem does NOT apply.
B.)
Begin by ensuring that the function is continuous.
The function is a polynomial, so it satisfies the conditions of the function being BOTH continuous and differentiable on the given interval (All x-values do as well in this instance). We can proceed to find the values that satisfy the MVT:
Begin by finding the average rate of change over the interval:
Now, Find the derivative of the function:
g(x) = 2x² - 4x + 3
Apply power rule:
g'(x) = 4x - 4
Find the x value in which the derivative equals the AROC:
4x - 4 = -2
Add 4 to both sides:
4x = 2
Divide both sides by 4:
x = 1/2
