$44j^5k^4=2^2\cdot11\cdot j^5 \cdot k^4\\ 121j^2k^6=11^2\cdot j^2 \cdot k^6\\\\ \text{gcf}( 44j^5k^4 ,121j^2k^6)=11j^2k^4$

Answer:

1)Area of circle: 64 $\pi$

2)Area of semicircles: 128 $\pi$

3)Area of quarter-circles: 128 $\pi$

4)Total area of pattern: 320 $\pi$

Step-by-step explanation:

r = 8cm

Given: 1 circle, 4 semicircles, and 8 quarter-circles.

Area of a circle: $\pi r^{2}$

1) A = $\pi r^{2}$ where r = 8

A = 64 $\pi$

2) 4 semicircles = 2 circles

so the answer is 2*A = 128 $\pi$

3) 8 quarter-circles = 2 circles

Therefore, the answer here is the same as the answer for #2!

4)There are 5 circles total because:

1 circle = 1 circle

4 semicircles divided by 2 = 2 circles (because $\frac{1}{2}$ times 4)

8 quarter-circles divided by 4 (think about what "quarter" means) = 2 circles

So ... 1 + 2 + 2 = 5 circles

Now we need to find the area of 5 circles which is just 5*A

5*A = 320 $\pi$

Help as soon possible thank you

<u>Answer:</u>

The correct answer option is D. (-2, 1).

<u>Step-by-step explanation:</u>

We are given the coordinates of the square A"B"C"D" after the rule is applied and we are to find the coordinates of the vertex A.

For that, we will reverse the rule.

A" = (-5, -3)

x: - 5 + 4 = -1

y: - 3 + 1 = -2

Now we will reverse the 90 degrees counter in counter clockwise rotation:

(x, y) ---> (y, -x)

(-1. -2) ---> (-2, -(-1)) = (-2, 1)

write in slope intercept form an equation of the line that passes through the points (-15, -1) and (10,4)

k0ka [10]

Find the slope first
m=y2-y1/x2-x1
m=4+1/10+15
m=5/25 = 1/5
use point slope formula and plug in any points
y-y1=m(x-x1)
y-4=1/5(x-10)
y-4=1/5x-2
y=1/5x+2
