Answer:
D
Step-by-step explanation:
Triangle Side Theorem: The two smaller sides of a triangle
must be greater than the largest side
8 + 9 > 16
X^2+ y^2=109
x 2 + y2 = 109
Step 1: Add -y^2 to both sides.
x 2 + y2 + − y2 = 109 + − y2
x 2 = − y2 + 109
Step 2: Take square root.
x = − y2 + 109 or x = − − y2 + 109
Answer:
x = − y2 + 109 or x = − − y2 + 109 CALCULATE IT
Solve for Variable
x-7=1/3y^2
x − 7 = 1
3 y2
Step 1: Add 7 to both sides.
x − 7 + 7 = 1
3 y2 + 7
x = 1
3 y2 + 7
Answer:
x = 1
3 y2 + 7
Answer:
A
Step-by-step explanation:
If you plug in 0 for w, the number of weeks, you'll see that s = 80. Meaning, at week 0 he ha 80
Find the speed per hour by dividing total distance by total time:
70 miles / 3 hours = 23 1/3 miles per hour.
1 mile = 1609 meters:
multiply miles by 1609:
23 1/3 x 1609 = 37,543 1/3 meters per hour.
<span>P(x) = –x4 + x3 + 7x2 − x − 6
The graph will look like a bell, or a downward facing parabola, since the dominant term is -x^4
The graph has a y-intercept of -6, which can be considered the fixed cost (cost of zero trees cut) and moves upward from there, eventually reaching a maximum at some positive number of trees and dropping again. As x gets very large, profit becomes a very large negative number. Since we can't have negative trees cut, we're only interested in positive x values
The company breaks even at P(x) = 0
0 = </span> –x4 + x3 + 7x2 − x − 6, x greater than zero
0 = (x+2)(x+1)(x-1)(x-3)
The company breaks even at 1 tree and 3 trees.
