–(x^2–2x+12) would become –x^2+2x–12.
3x^2+9x+13 – x^2+2x–12
= 2x^2 + 11x – 1
The formula for the circumference of a circle is
C = 2π·r
or
r = C/(2π)
The radius r of cylinder A is
r = (4π)/(2π) = 2
The formula for the area of a circle is
A = π·r²
or
r = √(A/π)
The radius of cylinder B is
r = √(9π/π) = 3
The dimensions of cylinder A must be multiplied by 3/2 to produce the corresponding dimensions of cylinder B.
Answer:
This is an example of an positive relationship.
Step-by-step explanation:
As the values for one variable decrease from one person to another, the values for a second variable also tend to decrease. This is an example of an positive relationship.
Answer:
320cm^2
Step-by-step explanation:
Surface area is the sum of areas of each side of the shape:
Area of cross section x 2 = 1/2 x 8 x 2 x 15 = 8 x 15 = 240cm^2
Area of base = 15 x 2 = 30cm^2
Area of slope = 17 x 2 = 34cm^2
Area of back = 8 x 2 = 16cm^2.
Now, surface area of whole shape is the sum of these areas:
16+30+34+240 = 320cm^2
Hope this helps.
I hope you are well, too.
Good Luck with math.
