Answer:

The large squares represent X squared, and had two sides, blue and red, to determine whether it is positive or negative (blue = positive, red = negative). There is also the long rectangles that represent X, with the positive side being green and the negative red. The side length of X is the same side length of X squared, which makes sense because X multiplied by X equals X squared. The smallest square pieces represent the number 1. The colours are yellow for positive and red for negative. These are the basic pieces used in algebra tiles. Hope this helps

Write the product as the product of a whole number and unit fraction <br> 2x4/5=

Nimfa-mama [501]

Answer:

$1 \frac{3}{5}$

Step-by-step explanation:

The first step is to multiply the numbers of the numerator. Thus:

$\frac{2 \times 4}{5}$

$= \frac{8}{5}$

Writing the answer above as the product of a whole number and unit fraction (that is, mixed number), 5 goes in 8 1 time remainder 3. Therefore:

$= \frac{8}{5} = 1 \frac{3}{5}$

Find (f-g)(x) for the following functions. f(x) = 12x + 20 g(x) = –11x2 + 10x + 33

IRINA_888 [86]

Answer:

11x2 + 2x-13

Step-by-step explanation:

We must build the new function f-g, which turns to be a sum between polynomials.

f(x)-g(x)= 12x+20 + 11x2- 10x-33

f(x)-g(x)= 11x2 + 2x-13

alex needs to buy compressed air to fill 5 empty cylindrical tanks for his store. each tank is 12 feet deep and has a radius of

Yanka [14]

Volume of a cylinder = the area of the base x height of the cylinder
Area of base = $\pi$ r^2
A = 6^2( $\pi$ )
A = 36 $\pi$
V = 36 $\pi$ x 12
V = 432 $\pi$

5 cylinders = 5V

5V = 5 x (432 $\pi$ )
5V = 2160 $\pi$

Final answer: Alex needs to buy 2160 $\pi$ or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.

What is the equation of this line?

elena-14-01-66 [18.8K]

Answer:

A) y = 4/3 x - 1/3

Step-by-step explanation:

(4,5) and (-2,-3)

Slope = (5 + 3)/(4 + 2)

= 8/6

= 4/3

Equation

y + 3 = 4/3(x + 2)

y + 3 = 4/3 x + 8/3

y = 4/3 x + 8/3 - 9/3

y = 4/3 x - 1/3

Answer:

y = 4/3 x - 1/3

The heights of adult females are normally distributed. If you were to construct a histogram of 40 randomly selected women, what

Anna11 [10]

Answer:

d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.

Step-by-step explanation:

Since the variable is normally distributed, the histogram of women's height should be approximately bell shaped (if the data was obtained form a random sample).

Again, the variable is normally distributed, therefore, the quantile plot should follow a straight line pattern (a diagonal line to be more precise).
