A rational number is any number that can be written as a ratio of two integers.

0.62 fits the bill, as it can be written as the ratio 62/100 (or simplified to the ratio 31/50)

Find the derivative of g(y)=(y-4)*(2y+y^2)

sasho [114]

Answer:

$g'(y)=3y^2-4y-8$

Step-by-step explanation:

start by foiling out the given function

$g(y)=(y-4)(2y+y^2)\\=2y^2+y^3-8y-4y^2\\=y^3-2y^2-8y$

next, use the power rule to find the derivative

power rule: To use the power rule, multiply the variable's exponent n, by its coefficient a, then subtract 1 from the exponent. If there's no coefficient (the coefficient is 1), then the exponent will become the new coefficient.

$g'(y)=3y^2-4y-8$

Katy and Jane construct a four-sided wall to surround their castle. The wall has a perimeter of

PilotLPTM [1.2K]

Answer:

The correct length is 34 feet.

Step-by-step explanation:

Let us assume that the wall created is a rectangle ABCD as shown in the attached image.

We know that opposite sides of a rectangle are equal.

Perimeter of a closed figure is calculated by adding all the sides of the figure.

Here, from the figure, the perimeter is : AB + BC + CD + DA

AB and CD are equal to length.

BC and DA are equal to width.

So,

$Perimeter = 2 \times (length + width) ....... (1)$

Here, we are given that perimeter is 100 feet and width = 16 feet

Putting values in equation (1):

$100 = 2 \times (16 + length)\\\Rightarrow 50 = 16 + length \\\Rightarrow length = 34 feet$

Hence, length is 34 feet.
