Well, if one face has an area of 81 square centimeters, then that means that each side of the square is 9 centimeters. The formula to find volume is
, so 9^3 = 729.
In short, your answer would just be 729 centimeters

If it is perpendicular to the line 14x-7y=4, then we know our line has the opposite and inverse slope of that line. Solving for y of the first line, we get y=2x-(4/7). All we care about is the coefficient of the x term, because that will give us our slope. The slope of the first line is 2, so the slope of out line is the opposite and inverse of that slope, which -(1/2).
Plugging into our slope- point formula, where y1=(-9), x1=2, and m=(-1/2), then:
y-(-9)=(-1/2)(x-2)
y+9=(-1/2)x+1
y=(-1/2)x-8

please help help me me my question solve
Answer:
Step-by-step explanation:
The cost function is expressed in dollars as
C(x) = 14980 + 20x
The revenue function is expressed in dollars as
R(x) = 30x
a) At the point of break even, the total cost equals the total revenue. There is neither profit nor loss. Therefore, the the number of units that must be produced and sold to break even would be
14980 + 20x = 30x
30x - 20x = 14980
10x = 14980
x = 1498
1498 mist be produced and sold to break even.
At this level, the dollar amount coming in and going out is
30 × 1498 = $44940
b) Profit = Revenue - cost
P(x) = R(x) - C(x)
P(x) = 30x - (14980 + 20x)
P(x) = 30x - 14980 - 20x
P(x) = 10x - 14980
