The elevation gained after travelling 1.5 miles = 3960 ft.
Step-by-step explanation:
Given data,
Angle of elevation = 30°
Distance traveled= 1.5 miles
1 mile = 5280 ft.
Therefore 1.5 miles = 5280 x 1.5
= 7920 ft.
The height can be calculated by,
sin 30° = height / 7920
1/2 = height / 7920
Height = 7920/2
= 3960 ft.
The elevation gained after travelling 1.5 miles will be 3960 ft.
Hi there! To find the answer, we need to try out the numbers. 3 * -3 is -9 + 0 is -9. -9 < -8. A is out. 3 * -2 is -6 + -1 = -7. -7 > -8. B works. Score! But wait. 3 * 0 is 0 + 10 is -10. -10 < -8. C is out. 3 * 2 is 6 + -16 is -10. -10 < -8. The answer is B: (-2, -1).
This question out to be one that we could all answer almost instantly. If the area under the std. norm. curve to the left of z is 0.5 (exactly half of that area), the z value is zero (0).
