2) Suppose that circles A and B have a central angle measuring 40°. Additionally, circle A has a radius of 5 2 ft and the radius

sleet_krkn [62]

Let

rA--------> radius of the circle A

rB-------> radius of the circle B

SA------> the area of the sector for circle A

SB------> the area of the sector for circle B

we have that

rA=5/2 ft

rB=9/2 ft

rA/rB=5/9-----------> rB/rA=9/5

SA=(25/36)π ft²

we know that

if Both circle A and circle B have a central angle , the square of the ratio of the radius of circle A to the radius of circle B is equals to the ratio of the area of the sector for circle A to the area of the sector for circle B

(rA/rB) ^2=SA/SB-----> SB=SA*(rB/rA) ^2----> SB=(9/5) ^2*(25/36)π--->

the answer is

<span>the measure of the sector for circle B is (9/4)π ft²</span>

write the slope intercept form of an equation of the line that passes through (4,3) that is perpendicular to the line Y=-3x-15

cricket20 [7]

If two lines are perpendicular, then their slopes have a product of -1 or you could say they are opposite signed reciprocals of each other.
The given equation has a slope of -3. We know this because it is in slope-intercept form y = mx + b ...y = (slope)x + (y-intercept).

so taking the slope -3...the opposite signed reciprocal would be + $\frac{1}{3}$

Now we have a slope and a point... we can use them to find the b (y-intercept)
x = 4, y = 3, and m = $\frac{1}{3}$
$3= \frac{1}{3} (4)+b$
$3= \frac{4}{3} +b$
Using the common denominator fraction for 3, we subtract 4/3 from both sides
$3= \frac{9}{3}$
$\frac{5}{3} =b$
plug the values for m and b into the slope intercept form
$y= \frac{1}{3} x+ \frac{5}{3}$
