Midland Oil has $1,000 par value bonds outstanding at 11% interest. The bonds will mature in 20 years. Compute the current price of the bonds if the present yield to maturity is 6%.

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

47 - 90 = 43

43 - 180 = x

x = 137

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
