Answer:
The minimum value of this quadratic function is -4.
At the point (-4, 0), the x-axis intercepts with the quadratic graph.
There is 1 root of this quadratic equation.
Approximately, when y=1, the x value could be -5 or -3.
3x-4y=12
4y=3x-12
y=(3x-12)/4
y=(3/4)x-3
Question 9 answer is 80 and for 10 it is 72 and for 11 it is 112 and for 12 it is 143
Perimeter = 2width + 2length
p=2(6)+2(9)
p=12+18
p=30
You need 30 inches of silver.
30x.25=7.50
The answer is $7.50.
Answer:
D. 1024 π units²
Step-by-step explanation:
We have sphere, with a radius of 16 units.
The surface area of a sphere is given by the following formula:
Surface Area of a sphere = 4 π r²
We already know r, which is 16. So,
SA = 4 * π * 16² = 256 * 4 * π = 1024 π units²
That's enough for our answer, which matches answer D from the list.
If we want to have an actual number.... we would have to multiply 1024 by π.
SA = 1024 * π = 3217 units²
