Answer:
A.
Step-by-step explanation:
Sub in the (x,y) points given into the equation to see if true ....you'll find A is the answer
Example point (3,95 ) 95 = -10.375 (3) + 126.125 ??
95 = 95 Check !
then try the other point ( 11,12) to be sure ....
L=22w (w=width, l=length)
l*w=2626
Substitute 22w for l, getting 22w^2=2626. Divide by 22 to get 119.36 (and more decimals!), and square root that to get 10.9 (rounded) for the width and 240.4 (rounded) for the length
Answer:
1200feet
Step-by-step explanation:
Given the the road's curve elevation modeled by the equation
y = 0.00005x^2 - 0.06x,
x is the horizontal distance in feet between the points where the road is at sea level and;
y is the elevation
The elevation the road is equal to sea level when y = 0
Substitute y = 0 into the equation and calculate x;
0 = 0.00005x^2 - 0.06x
0.06x = 0.00005x^2
0.06 = 0.00005x
x = 0.06/0.00005
x = 1200 ft
Hence they will place the stop sign at a horizontal distance of 1200feet
