A section of a highway is constructed with a 11% grade. What angle does the highway make with a horizontal line? Round to the nearest hundredth of a degree. m∠A ≈ 84.81°
m∠A ≈ 83.72°
m∠A ≈ 6.28°
m∠A ≈ 5.19°

the answer is d

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
