Calculate the average rate of change for given function, from x=2 to x=7

LenaWriter [7]

"When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h) Therefore, the slope of the secant line between any two points on this function is 2x + h."

What is the measure of W the parallelogram shown?

nexus9112 [7]

Answer:

148 degrees

Step-by-step explanation:

For a parallelogram, angles on the same side sum up to be 180

what this simply means is that they are supplementary

Mathematically, we have it that;

X + W = 180

W = 180 - X

W = 180 -32

W = 148 degree

The area of triangle abc is 6 square centimeters. Ab is parallel to de . Bd=4bc . What is the number of square centimeters in th

cestrela7 [59]

It is given that area( Δ ab c) =6 square units.

Also ab║d e

⇒b d =4 b c

I have depicted picture below.

Consider Δ cde in which points a and b are in the interior such that ab║de.

So, as you know that if in a triangle line joining two points is parallel to third side then the two sides are proportional.i.e

⇒ca/ae =cb / bd

Also, ∠ c is common.

∴Δcab is similar to Δ cde.

As we know if ratio of areas of two similar triangles is square of their corresponding sides.

= $\frac{Ar(Δcab)}{Ar(Δcde)}=[\frac{cb}{bd}]^2$

⇒6/Δcde =1/4

⇒Ar (Δ cde)=6×4

Ar (Δ cde) =24 square centimeter
