For this case we have the following equation:
y = 100 - 8.9x
Where,
x = the number of hours of use
For 11 hours of use we have x = 11.
Substituting:
y = 100 - 8.9 * (11)
y = 2.1%
Answer:
the best prediction of the percent of remaining power for a battery after 11 hours of use is:
y = 2.1%
(3,7) becomes (3,-7) when reflected across the x axis.
Answer:
78.5
Step-by-step explanation:
area of a circle is 
3.14(
)=78.5
<span>Alright, here's your answer.
y-intercept is computed (not found) by assigning x = 0 and computing y: here that is f(0) = Log(2*0 + 1) – 1 = Log(1) – 1 = 0 – 1 = -1
y-intercept is (0, -1)
x-intercept is computed by solving f(x) = 0 for x: here that is
0 = Log(2x + 1) – 1 → 1 = Log(2x + 1)
Assuming the Log cited is base 10, then 10^1 = 10^Log(2x + 1) = 2x + 1
That’s 10 = 2x + 1
Therefore 9 = 2x
x = 9/2 = 4.5
Check this result in the original equation, I did!
Your answer is - x-intercept is (4.5, 0)
I hope I helped! :)
