Answer:

Step-by-step explanation:
Assuming that the first exponent in the formula for the curve should be 3, not 2...

The derivative is

The slope of the tangent line at the point (-1, 2) is the value of the derivative at x = -1.

The slope of the normal line is the opposite reciprocal of the slope of the tangent line.

Using the Point-Slope form of a linear equation, the normal line is

Answer:
2
Step-by-step explanation:
Answer:
1:4
Step-by-step explanation:
Given
3: 12
To express in the form 1:n
Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3
3:12
= 3/3:12/3
= 1:4
Comparing with 1:n, it is safe to say that n = 4
Answer:
(-10,-7)
Step-by-step explanation:
first reflect over x=-3
(-7,-10)
then reflect over y=x
(-10,-7)
513 as a percentage of 900 can be re-written as;

= 57 percent
