Answer:
look at this image fpr answer .it is right
Answer:
I believe the answer is 2,904 if i did it right.
Step-by-step explanation:
All you have to do is take the original number 2,200 and multiply it by .32 because you change the percent into a decimal by moving the decimal place twice. then add it back to 2,200.
2,200x.32+2,200=2.904
Answer:
.
Step-by-step explanation:
The equation of a circle of radius centered at is:
.
.
Differentiate implicitly with respect to to find the slope of tangents to this circle.
.
Apply the power rule and the chain rule. Treat as a function of , .
.
.
That is:
.
Solve this equation for :
.
The slope of the tangent to this circle at point will thus equal
.
Apply the slope-point of a line in a cartesian plane:
, where
- is the gradient of this line, and
- are the coordinates of a point on that line.
For the tangent line in this question:
- ,
- .
The equation of this tangent line will thus be:
.
That simplifies to
.
