Triangle QNP was dilated by a scale factor of One-third about point P. It was then transformed in another way to produce Triangl

e Q prime N prime P prime.
On a coordinate plane, triangle Q N P has points (negative 1, 0), (negative 7, 9), (negative 1, 9). Triangle Q prime N prime P prime has points (6, 1), (9, 3), (9, 1).


Which identifies the transformation that occurred after the dilation?

a 90 degrees clockwise rotation about the origin

a 180 degrees clockwise rotation about the origin

a reflection across the x-axis

What is the volume of a square pyramids
frozen [14]

Answer:

\large\boxed{V=75\ in^3}

Step-by-step explanation:

The formula ogf a volume of  a pyramid:

V=\dfrac{1}{3}BH

B - area of a base

H - height

We have a base length a = 5 in and a height H = 9 in.

In the base we have a square. The formula of an area of a square is:

B=a^2

Substitute:

B=5^2=25\ in^2

Calculate the volume:

V=\dfrac{1}{3}(25)(9)=(25)(3)=75\ in^3

Draw a line having a slope of 1/3 and y-intercept of -1
Lilit [14]
Equation for slope=1/3 and y-intercept=-1 is:
y = mx + b
where m is slope and b is y-intercept.
So, equation becomes
y = -1x + 1/3
Now put different values of x in the equation to get corresponding value of y.
x          y
0         1/3
1        -2/3
2        -5/3
3        -8/3
-1       4/3
-2       7/3
-3       10/3

Evaluate f(x) = x2 – 12 when x = 5
Ede4ka [16]

Answer:

f(5) = 13

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Function notation and substitution

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = x² - 12

x = 5

<u>Step 2: Evaluate</u>

  1. Substitute:                   f(5) = 5² - 12
  2. Exponents:                  f(5) = 25 - 12
  3. Subtract:                      f(5) = 13
