Answer:
313 in.
Step-by-step explanation:
V = r × h
10,000 = 32 × ?
10,000 / 32 = 312.5
312.5 rounded to the nearest whole number is 313 in.
Answer:
Perimeter = 156
Area = 1029
Step-by-step explanation:
Perimeter = 65 +42 49
P = 156
Area = 49*42/2
A = 1029
1/7 (x - 3) = 5/7
1/7x - 3/7 = 5/7
1/7x - 3/7 + 3/7 = 5/7 + 3/7
1/7x = 8/7
1/7x(7) = 8/7(7)
X = 56/7
X = 8
To graph the equation, plot a few points then connect then with a line.
f(x) = 440 - 55x
Plug in numbers for x to get the y value.
f(0) = 440
f(1) = 385
f(2) = 330
f(3) = 275
f(4) = 220
f(5) = 165
So when you graph these points, the y intercept is y = 440 because the graph crosses the y axis at (0, 440).
The x intercept is where the graph crosses the x axis. This happens when y = 0.
0 = 440 - 55x. Solve for x.
55x = 440
x = 8
So the x intercept is x = 8
