D=r^2 means diameter equals radius squared

egoroff_w [7]2 years ago

3 0

The equation d=2r is used in geometry to find the diameter of a circle when its radius is know. d represents, and r represents the radius. This formula is explained by the fact that the diameter of a circle is equal to 2 times the length of its radius.
For example, if we have a circle with a radius of 4, and we need to find its diameter we can use the formula d = 2r:
d = 2r = 2*4 = 8

Hope this Helps! :)

How do you solve this? A and B

svp [43]

An adult polar bear is 8 times longer than a newborn.
Newborn= 12 1/2 ft
Multiply this by 8.
But first you have to turn the fraction
12 1/2 into an improper fraction. To do this you have to multiply the denominator, 2, by the whole number, 12, and add the numerator to the product, which totals to 25. The fraction is 25/2. (25/2 * 8/1)= 100 in simplified. 100 inches= 8 1/3 ft long
A= 8 1/3 ft long.
For B, you are dividing since you are trying to figure out the length of a newborn, not an adult polar bear. 9/8 turned into a mixed fraction is
1 1/8 ft. But, it asks in inches.
B= 13 1/2 inches
I know this answer is very long but I hope it helps you understand better!

Simplify. 5(22 - 9 · 2) - 2( 3 · 2 4) 7 a.-99 b.-83 c.-75 d.-71

Pachacha [2.7K]

Not completely sure on the symbols, but I think it is 5 x ( 22 - 9 x 2 ) - 2 ( 3 x 2 x 4 ) x 7 = 136. It doesn't really match the answers, so my advice is that you use a calculator for this one, or as the person/teacher who gave you the problem how to solve it.

HELP ASAP

qwelly [4]

The center of dilation Y is the point from which the other points expand or

contract away from or towards.

The true statement about A'Y' is; Line A' Y' passes through the center of dilation..

The given parameters are;

The scale factor of dilation of ΔXYZ = 3

The point of dilation = Point Y

Line YA is vertical (perpendicular) to the base XZ

In a dilation transformation, the extension or compression of the points

are relative to the center of dilation.

Following the dilation, the line AY is extended along AY to A' Y', therefore,

passing through the point Y which is the center of dilation.

The option that is true is therefore; Line A' Y' passes through the center of

dilation (which is written as line A prime Y prime passes through the center

of dilation).
