That's an equilateral right rectangular parallepiped,
usually referred to as simply a "kewb".

Me. Pennington had 6 inches left over.

Explanation.
2 1/4 feet is equal to 27 inches. If he used 21 inches, then he'd had 6 inches left over; 27-21=6.

Have a good day!

What direction is 45 degrees in clockwise from due east?

MrRa [10]

Since you requested I answer this, I will do my best, but I'm not sure I can explain it well.

45° clockwise from due east is just 45° from the east. Moving clockwise, which is the direction the hands of a clock move, you're going to the south, and since it's by 45°, you're halfway between east and south, so you're southeast.

Answer:

[1].

Option A and D are correct.

[2].

Option A is correct

Step-by-step explanation:

[1].

Quadratic function states that it is an equation of second degree i.,e it contains at least one term that is squared.

The standard form of the quadratic equation is; $ax^2+bx+c = 0$

A.

$y(y+4)-y = 6$

Using distributive property: $a\cdot (b+c) = a\cdot b + a\cdot c$

$y^2+4y-y=6$

Combine like terms;

$y^2+3y = 6$

or

$y^2+3y -6=0$ which represents a quadratic equation.

B.

$3a-7 = 2(7a-3)$

$3a-7 = 14a-6$

or

$11a+1 = 0$ which is not a quadratic equation.

C.

(3x+2)+(6x-1) = 0

Combine like terms;

9x +1 = 0 which is not a quadratic equation.

D.

4b(b) = 0

$4b^2 = 0$ which represents the quadratic equation.

[2].

Given the parent function: $y=x^2$

The reflection rule over x axis is given by;

$(x, y) \rightarrow (x, -y)$

then

the function become: $y = -x^2$

Vertical shift:

If c is a positive real number, the graph y=f(x)+c is the graph of y =f(x) shifted upward c units.

If c is a positive real number, the graph y=f(x)-c is the graph of y =f(x) shifted downward c units.

then;

The graph $y=-x^2-3$ is the graph of $y=-x^2$ shifted 3 units down.

Therefore, the translation of the graph of $y=x^2$ to obtain $y=-x^2-3$ is, reflect over the x-axis and shift down 3

this triangular prism has a length of 20 centimeters, an end base of 6 centimeters and an end height of 8 centimeters. what is t

antoniya [11.8K]

Answer:

The volume of the triangular prism is 480 cm³.

Step-by-step explanation:

The volume of a triangular prism is:

$V=\frac{1}{2}\times \text{b}\times \text{h}\times \text{l}$

Here,

b = base

h = height

l = length

The information provided is:

b = 6 cm

h = 8 cm

l = 20 cm

Compute the volume of the triangular prism as follows:

$V=\frac{1}{2}\times \text{b}\times \text{h}\times \text{l}$

$=\frac{1}{2}\times 6\times 8\times 20\\\\=6\times 8\times 10\\\\=480\ \text{cm}^{3}$

Thus, the volume of the triangular prism is 480 cm³.
