Answer:
b=4
Step-by-step explanation:
g(x)=x^2+bx+11
When x = -1 g(x) = 8
8 = (-1)^2 +b(-1) +11
8 = 1 -b+11
Combine terms
8 = 12-b
Subtract 12 from each side
8-12 = 12-b-12
-4 = -b
Multiply by -1
4 = b
Answer:
There will be viewers in 1 year
640 people will see the video on 7th day
Step-by-step explanation:
On the day a video was posted online, 5 people watched the video.
Initial viewers = 5
The next month the number of viewers had doubled.
Assume the number of viewers continues to double each day.
Formula:
Where a is the initial amount
b is the rate
t is time in days
1) We are supposed to find the no. of viewers in 1 year
1 year =
So,
2)Estimate on which day will 640 people see the video?
So, y = 640
So,
So, t = 7
Hence 640 people will see the video on 7th day
Hello :)
Slope intercept form: y = mx+b
Perpendicular: forms a right angle (90°)
We are asked to write the linear equation (written in slope intercept form) that passes through (-2,-11) and is perpendicular to
to do this we need to find the perpendicular line using the point.
Step 1: use the point slope formula: to find the line perpendicular to
m=4; we got 4 because we were supposed to find the negative reciprocal of the slope of the original line by multiplying -(1/4) by (-1).
y=4x-3
we can check this by seeing that when we graph it, the line passes through (-2,-11) , and it is also perpendicular to
