Let y = safe load in pounds and x = depth in inches for a certain type of rectangular horizontal beam. a constant of proportionality exists such that y = kx². determine the constant k for a beam with y = 1,000 pounds and x = 5 inches. a. 40 b.100 c.200

40

Step-by-step explanation: I got it right on OW

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
