Answer:
D. 75 m²
Step-by-step explanation:
l = 15m
b = 5m
area of rectangle = l × b = 15 × 5 = 75 m²
The plane must be 3.38 miles away from the runway to begin the descent. The equation I used was "y = -0.1111111x + 0.3755682", 0.37~ being the height in feet (in miles) and -0.11~ being the descent. The x-intercept is located at 3.38.
Answer:
y=2.50x+4.00
over here the gradient is 2.50
and the y-intercept is 4.00
so in the first one, start Drawing the line from 4 on y axis
So a few points would be: (0,4) (1,6.5) (2,9) (3,11.5) (4,14)
second equation...
y=2.00x+5.00
gradient is 2.00
and y intercept is 5
so draw the line from 5 on the y axis
A few points would be: (0,5) (1,7) (2,9) (3,11) (4,13)
As you see, I got the common point (2,9) in both, so they intersect at (2,9)
The answer is B. 400/3 ft3
