We breakdown the components of the distances.
(1) 90 miles west.
x - component = -90 miles
y - component = 0 miles
(2) 80 miles, northwest (120°)
x - component = (80 miles)*(sin 30°) = 40 miles (negative)
y - component =(80 miles)*(cos 30°) = 69.282 miles (positive)
Solve for the distance,
√(-90 - - 40)² + (69.282 miles)² = <em>147.31 miles</em>
Answer: -27
Step-by-step explanation: the cube has a volume of -27 because -3 to the 3rd power (cubed) is -27
Hope this helps ☺
No it does not have one line of symmetry
Answer:
4. -6
5. -5
6. 2
Step-by-step explanation:
4.
2x + 3 <= -9
2x <= -9 - 3
2x <= -12
= x <= -6
5.
3p + 4 > -11
3p > -11 -4
3p > -15
p > -5
6.
5x + 6 >= 16
5x >= 16 - 6
5x >= 10
x >= 2
