The sides of a square all have a side length of y. Write a simplified area function in terms of y for a rectangle whose length i

gizmo_the_mogwai [7]

The simplified area function in terms of y for a rectangle is $f(y)=2 y^{2}+4 y$

Solution:

Given that length of each side of a square = y

Need to determine area of rectangle whose length is twice the length of the square and width is 2 units longer that the side length of square

Length of rectangle = twice of side length of square = $2 \times y = 2y$

Width of rectangle = 2 + side length of square = 2 + y = y + 2

$\text { Area of rectangle }=\text { length of rectangle } \times \text { width of rectangle.}$

On substituting length and width in formula for area, we get

$\text { Area of rectangle }=2 y \times (y+2)=2 y^{2}+4 y$

Hence function $f(y)=2 y^{2}+4 y$ is represents area of required rectangle.

Small cubes with edge lenghts of 1/4 will be packed into the rectangular prism how many small cubes will be needed to completley

Olegator [25]

Answer:

9216

Step-by-step explanation:

number of small cubes that would fill the prism = volume of prism / volume of small cubes

volume of a prism = length x width x height

3 x 6 x 8 = 144

volume of cube = length³

(1/4)³ = 1/64

144 ÷ 1/64

144 x 64 = 9216

Explain how solving -4t < 32 is different from solving 4t <-32.

Thanks for the question!

When you multiply or divide both sides of an inequality, you flip the sign. "Flip," meaning greater than becomes less than and less that becomes greater than.

Hope this helps!

The data set below shows prices for concert tickets in 10 major cities. Find the interquartile range (IQR) of the set. How do t

Llana [10]

Answer: IQR = 16

Step-by-step explanation:

Given the following data:

Cost of concert :

CITY : Q, R, S, T, U, V, W, X, Y, Z

Price : 35,36,42,38, 24,29,25, 44,49, 26

Interquartile range (IQR) = Q3 - Q1

Where,

Q3 = the upper quartile

Q1 = lower quartile

Rearranging the data:

24,25,26,29,35,36,38,42,44,49

Q3 = 42

Q1 = 26

IQR = (42 - 26) = 16
