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

Step-by-step explanation:
10 of them fail so 10 of them get 0 and no points to there GPA
Answer: the diameter of the cone is 1.6m
Step-by-step explanation:
The formula for determining the curved surface area of a cone is expressed as
Area = πrl
Where
r represents the radius of the cone.
l represents the slant height of the cone.
π is a constant whose value is 3.14
From the information given,
the curved surface area of the cone is 6.28 square meters
slant height = 2.5 meters.
Therefore,
3.14 × 2.5 × r = 6.28
7.85r = 6.28
r = 6.28/7.85
r = 0.8
Diameter = 2 × radius
Diameter = 2 × 0.8 = 1.6 meters
Answer:
First we need to find the slope. This is (7 - 3) / (4 - 2) = 2. Since we know the slope, we can use point-slope form. I'm using the point (2, 3).
y - 3 = 2(x - 2)
y - 3 = 2x - 4
y = 2x - 1
