When we have exponents like such (x^-6)^-2 , the numbers are multiplying, so we have x^12, then we take that value and, because it is dividing with the same base, we substract the numbers, so x^12-(-4) = x^16.

The points (a,5) and (9,b) are on the circle x^2+ y^2= 125.

Aneli [31]

Answer:

a = 10

b = 6.633

Step-by-step explanation:

x²+ y²= 125.

In this equation, the value of x and y represent the coordinates of x and y respectively of point on which the circle passes.

x²+ y²= 125

a² + 5² = 125

a² + 25 = 125

a² = 125-25

a² = 100

a = √100 = 10

(9,b)

x²+ y²= 125

9² + b² = 125

b² 125 - 81

b² = 44

b = √44 = 6.633

Use the Euclidean algorithm to find the greatest common divisor d of 313,626 and 152,346. Then use this algorithm to find intege

Marat540 [252]

313,626 = 2 * 152,346 + 8934

152,346 = 17 * 8,934 + 468

8,934 = 19 * 468 + 42

468 = 11 * 42 + 6

6 divides 42, so the GCD of 313,626 and 152,346 is 6.

Mary's making curtains out of some fabric for five Windows the two larger windows are the same size and the three smaller window

pochemuha

So we have 2 large windows, each needing 3 3/4 yds of fabric....and 3 small windows, each needing 1 1/3 yds of fabric

2(3 3/4) + 3(1 1/3) =
2(15/4) + 3(4/3) =
30/4 + 12/3 =
7 1/2 + 4 =
11 1/2 (or 11.5) yds of fabric are needed <==
