The area of a circle is:
a=πr^2 dividing both sides by π
r^2=a/π taking the square root of both sides
r=√(a/π), in this case a=44 m^2 so:
r=√(44/π) m^2
r≈14.01 m^2 (to the nearest hundredth of a square meter)
Answer:
(-1,3)
y=5x+8 , y=-4x-1y=5x+8,y=−4x−1
Both sides have y on the left hand side so make the right hand side equal and solve for x
5x+8= -4x-15x+8=−4x−1
To solve for x , add 4x on both sides
9x+8=-19x+8=−1
Subtract 8 on both sides
9x=-99x=−9
Divide by 9 on both sides
x=-1x=−1
Now plug in -1 for x in the first equation and find out y
y=5x+8y=5x+8
y=5(-1)+8y=5(−1)+8
y=-5+8y=−5+8
y=3y=3
Ordered pair is (x,y) that is (-1,3)

Answer:
6.065; 7.358 ; 6.694
Step-by-step explanation:
Given that, profit is quoted using the function :
R = 2pe ^ -0.1p
(a)
When price 'p' = $5
R = 2(5)e^(-0.1*5)
R = 10e^(-0.5)
R = 10 * 0.6065306
R = 6.065
B)
When price 'p' = $10
R = 2(10)e^(-0.1*10)
R = 20e^(-1)
R = 20 * 0.3678794
R = 7.358
C.)
When price 'p' = $15
R = 2(15)e^(-0.1*15)
R = 30e^(-1.5)
R = 30 * 0.2231301
R = 6.694
50 degrees I’m guessing is the answer
