The main cable of a suspension bridge is modeled by the equation y=0.0048(x - 50)2 + 6. At what
horizontal distances from the left support is the
cable 10 ft above the roadway?
y = height in feet of cable above the roadway
Choose the equation one must solve to answer the
question
O 0 = 0.0048(x - 50)2 + 6
10 =0.0048(x - 50)2 + 6
O y=0.0048(10 - 50)2 +6
DONE
x = horizontal distance in feet from left support

B on E2020

Step-by-step explanation:

The next one is 21 ft. and 79 ft.

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
