Geometry - The steps to rotating a shape on a graph.

1 answer:

6 0

(x,y)

Quartile 1/original coordinates (x,y)
Quartile 2 (-x,y)
Quartile 3 (-x,-y)
Quartile 4 (x,-y)

use this to move a shape on the graph

the degree of rotation of a shape on a graph depends on where the shape starts and ends

I need help with both questions, you can answer either exercise #2 or #4 or both if you want to.

KATRIN_1 [288]

For 2a, we plug 3 in to get (4*3+3)/(3^2-7)=15/2. Since 2 is a prime number and 15 is not divisible by 2, this is simplest form. For b, using PEMDAS, division goes before addition or subtraction and 3/3^3 would therefore be done and you could not add 4*3 beforehand (or subtract 7).

For 4a, we plug it in to get sqrt(25-(-3)^2)=sqrt(25-9)=sqrt(16)=4

For b, since 13^2=169 and 25-169 is negative, we cannot find the square root due to that nothing squared is negative.

What is b. If the number as a fraction is 56/90.

MA_775_DIABLO [31]

The answer is: " 28 " .
___________________________________________________
" Twenty-eight (28) students said they would vote for Brianna."
___________________________________________________
Explanation:
___________________________________________________
We are given, in the problem, that there are "45 students total" .
___________________________________________________
The fraction: $\frac{56}{90} ;$

can be reduced as follows:

$\frac{56}{90} = (56÷2) / (90÷2) = [tex] \frac{28}{45}$ .
___________________________________________________
Thus, "28 students out of 45 students voted for Brianna" .
___________________________________________________
The answer is: "28 students" .

Hope this helps!

Which of the following is the result of the equation below after completing the square and factoring? x^2-4x+2=10

Tamiku [17]

Answer:

B. (x-2)^2=12

Step-by-step explanation:

The constant that completes the square is the square of half the coefficient of the x-term. That value is (-4/2)^2 = 4.

There is already a constant of 2 on the left side of the equal sign, so we need to add 2 to both sides to bring that constant value up to 4.

x^2 -4x +2 = 10 . . . . . . . given

x^2 -4x +2 +2 = 10 +2 . . . . complete the square (add 2 to both sides)

(x -2)^2 = 12 . . . . . . . . . write as a square

Using the equation 4x^3-6x^2-144x+8, find the function values f(-3) and f(-4) at the interval {-4,5}

Leto [7]

Answer: f(-3) = 278, f(-4) = 232

Step-by-step explanation:

f(x) = 4x³ - 6x² - 144x + 8

f(-3) = 4(-3)³ - 6(-3)² - 144(-3) + 8

f(-3) = 4(-27) - 6(9) - 144(-3) + 8

f(-3) = 278

f(-4) = 4(-4)³ - 6(-4)² - 144(-4) + 8

f(-4) = 4(-64) - 6(16) - 144(-4) + 8

f(-4) = 232
