The Maximum and Minimum can not be determined on this problem because it isn't a quadratic function. Graphed, the highest point is 7 and lowest is -7 in a repeated mountain shape. Hope this helps.

Jeffrey has an aquarium in the shape of a rectangular prism. He is going to place a layer of sand over the base for his iguana.
nikitadnepr [17]

Answer:

Length = 6x^2 - 2x + 3

Step-by-step explanation:

Given

Area = 42x^3 - 14x^2 + 21x

Width = 7x

Required

Determine the length of the aquarium

The area of a rectangular base is calculated as:

Area = Length * Width

Substitute values for Area and Width

42x^3 - 14x^2 + 21x = Length * 7x

Make Length the subject

Length = \frac{42x^3 - 14x^2 + 21x}{7x}

Factorize the numerator

Length = \frac{7x(6x^2 - 2x + 3)}{7x}

Length = 6x^2 - 2x + 3

Amount = P(1+  \frac{r}{n}) ^{nt}

P is the amount you invested.
r is the interest rate in decimal form (so 6% = 0.06)
n is the number of times a year you are paid interest (semiannually = 2)
nt is the number of payment times you expected (4 years, twice a year = 8 times)

The radius of the base of a right circular cone is 7 times greater than the radius of another right circular cone. If the height
Simora [160]

Answer: option D is the correct answer.

Step-by-step explanation:

Let the height of both cones be h

The radius of the base of a right circular cone is 7 times greater than the radius of another right circular cone. If the radius of the smaller cone is r, then the radius of the larger cone is 7r.

The formula for determining the volume of a cone is expressed as

Volume = 1/3(πr²h)

Volume of the smaller cone is

1/3(πr²h)

Volume of the larger cone is

1/3(π ×(7r)²h)

= 1/3(π ×49r²h)

the volume of the larger cone divided by the volume of the smaller cone is

1/3(π ×49r²h) / 1/3(πr²h) = 49/1 = 49
