Answer:
Step-by-step explanation:
Step 1: Factor left side of equation.
(c+1)(c+9)=0
Step 2: Set factors equal to 0.
c+1=0 or c+9=0
c=−1 or c=−9
C= -1 OR C= -9
Answer:
Area of Triangle = 1/2 bh
A = 1/2 (16 cm x 10 cm)
A = 160 cm2/2
A = 80 square cm
Area of Circle =
d2/4
A = 3.14 x (16 cm)2 / 4
A = 3.14 x 256 cm2 / 4
A = 803.84 cm2 / 4
A = 200.96 cm2
Area of Half Circle = 200.96 cm2 / 2
A = 100.48
Composite Figure = Area of Triangle + Area of half Circle
Area of Composite Figure = 80 cm2 + 100.48 cm2
Area of Composite Figure = 180.48 cm2
Solve the equation by replacing x with -7 and then -1.
Then subtract the two to find the difference and divide that by the difference between -7 and -1.
f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27
f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9
Difference between 27 and -9 = -36
Difference between -1 and -7 = -6
Rate of change = -36 /-6 = 6
8/6 or 1 2/6 or 1 1/4
Explanation:
1/4 + 1/4 = 2/4
2/4 = 3/6
5/6 + 3/6 = 8/6
8/6 simplified is 1 2/6 or 1 1/4
