Answer:
This is the answer because if you use the formula for volume (length x width x heighth) you will get this answer.
Answer:
201.06 square feet.
Step-by-step explanation:
=> The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.
=> The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.
=> Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet
The answer to the product of the functions f(x) = x2 and g(x) = x - 8 is f(x).g(x) = x3 - 8x2.
The given functions are :
f(x) = x2 --- (1)
g(x) = (x - 8) --- (2)
The product of the functions is obtained by multiplying equations (1) and (2)
f(x). g(x) = x2 × (x - 8)
f(x).g(x) = x3 - 8x2
Let us take another example
Let f(x) = x3 - 2x2 + x - 4 and g(x) = 1/2x
The product of the above two functions will be :
f(x).g(x) = (x3 - 2x2 + x - 4) × (1/2x)
= ( x3)(1/2x) -( 2x2)(1/2x) + (x)(1/2x) - (4)(1/2x)
= x2/2 - x + 1/2 - 2/x
= x2/2 - x - 2/x + 1/2
Answer:
21.99 inches
Step-by-step explanation:
Formula: C=2 pi r
First, turn the diameter to a radius by dividing 7 inches, the diameter, by 2. This turns out to be 3.5 inches.
Then, multiply 3.5 by pi(3.14), which would give you 10.99 inches.
Last, do the last step of the formula, which is multiplying 10.99 inches by 2.
Length = w+5
A = l x w
84 = w +5 x w
84 = w² + 5w
w = -12 or w = 7
Since you can't have a negative length W=7
Length = 7+5
length = 12
Width= 7
