Answer: The height of tree = 15 ft. 6 inches
Step-by-step explanation:
Given: A person's height is 5-ft 3-in = [5 x (12 )+3 ] inches [ 1 ft= 12 inches]
= 63 inches
Their shadow has a length of 3-ft 6-in = [3 x 12+6] inches
= 42 inches
If a nearby tree has a shadow of length 10-ft 4-in = [10 x 12+4] inches
= 124 inches.
At the same time,
Hence, the height of tree = 15 ft. 6 inches
Answer:
0.75:1
Step-by-step explanation:
2x - 20 = x + 15
x = 35
Now plug x in:
2*35 - 20 = 50 degrees
D = (5-1)/(13-(-3)) = 0.25
f(13) = 13d + x = 13 * 0.25 + a = 3.25 + a = 5
a = 1.75
f(x) = 1.75 + 0.25x
Answer:
Step-by-step explanation:
<u>Points given:</u>
- (-1, 3), (1, 1), (3, -1), (5, -3)
<u>Slope-intercept form:</u>
<u>Finding the slope using slope formula and the first two points:</u>
- m = (1 - 3)/(1 - (-1)) = -2 / 2 = -1
<u>Finding y-intercept using the slope and the first point:</u>
- 3 = (-1)*(-1) + b
- 3 = 1 + b
- b = 3 - 1
- b = 2
<u>So the equation is:</u>
