Answer:
A function corresponds to one unique value of x and y hence A
The area of circle is 113.04 in^2
Further explanation:
The area of circle is calculated by using pi and radius.
We are given
Diameter = d = 12 inches
pi = π = 3.14

Answer:
two solutions : (-3;4) and (-5;6)
Step-by-step explanation:
hello :
X²+y²+18x+29=0 ..(1)
X+y=1 ...(2)
by (2) : y = 1 - x
put this value in (1) : x² +(1-x)² +18x+29 = 0
x² +1 +x² -2x+18x +29 =0
2x²+16x +30 = 0
x²+8x+15 =0
delta = b²-4ac a=1 b=8 c = 15
delta = (8)²-4(1)(15)=64-60 =4 = 2²
X1=(-8+2)/2 = - 3
X2=(-8-2)/2 = - 5
case 1 : x = -3 y = 1 - (-3) = 4
case 2 : x = -5 y = 1 - (-5) = 6
Answer:
Because the sum of the interior angles of a triangle is 180,
X=180-(65+35)
X=180-100=80
Since F(X) = 3^X,
F(4) = 3^4 = 81
