X=20. By using the bottom sides of each figure, you can calculate that the figure on the right is 3 times larger than the similar figure on the left. This means that 2x+5=45. When solved, this yields x=20.

In circle V, r = 14ft.
Bad White [126]

For this case we have that by definition, the area of a circle is given by:

A = \pi * r ^ 2

Where:

r: It is the radius of the circle

According to the data of the statement we have that the circle has a radius of 14 \ ft

Substituting in the formula we have:

A = \pi * (14) ^ 2\\A = \pi * 196\\A = 196 \pi

So, the area of the circle is 196 \pi feet squared

Option D

Z^m-n (z^m+ z^m+n + z^n)
rusak2 [61]

Answer:Your left hand side evaluates to:

m+(−1)mn+(−1)m+(−1)mnp

and your right hand side evaluates to:

m+(−1)mn+(−1)m+np

After eliminating the common terms:

m+(−1)mn from both sides, we are left with showing:

(−1)m+(−1)mnp=(−1)m+np

If p=0, both sides are clearly equal, so assume p≠0, and we can (by cancellation) simply prove:

(−1)(−1)mn=(−1)n.

It should be clear that if m is even, we have equality (both sides are (−1)n), so we are down to the case where m is odd. In this case:

(−1)(−1)mn=(−1)−n=1(−1)n

Multiplying both sides by (−1)n then yields:

1=(−1)2n=[(−1)n]2 which is always true, no matter what n is

Use the graph of f to estimate the local maximum and local minimum.
Tpy6a [65]

Answer:

Option (4)

Step-by-step explanation:

From the graph attached,

A, B and C are the points based at the heights and valleys of the given curve.

y-coordinates of these points always decide, whether the point is a local maxima or local minima.

y-coordinate of A → -4

y-coordinate of B → 0

y-coordinate of C → -4

Ends of the curve are moving towards infinity, so the absolute maximum is not defined.

Local minimum → -4

Local maximum → 0

Therefore, point representing local maximum is B(0, 0).

Points representing local minimum are A(-2, -4) and C(2, -4).

Option (4) will be the correct option.

maxonik [38]

Answer:

Your answer is D. center of rotation!

Step-by-step explanation:

A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the center of rotation . The amount of rotation is called the angle of rotation and it is measured in degrees.
