An investor has $75,000 to invest in a cd and a mutual fund. the cd yields 7% and the mutual fund yields 8%. the mutual fund requires a minimum investment of $8,000, and the investor requires that at least twice as much should be invested in cds as in the mutual fund. how much should be invested in cds and how much in the mutual fund to maximize the return? what is the maximum return? n investor has $80, 000 to invest in a cd and a mutual fund. the cd yields 5% and the mutual fund yields 9%. the mutual fund requires a minimum investment of $10,000, and the investor requires that at least twice as much should be invested in cds as in the mutual fund. how much should be invested in cds and how much in the mutual fund to maximize the return? what is the maximum return?

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
