Triangle QRS has coordinates Q(–12,10), R(–8,8), S(–1,9). Give the coordinates of each vertex of the image after triangle QRS is dilated by a scale factor of 2.
Q’( , ) R’( , ) S’( , ).

Answers

Answer 1

Answer:

Q' = (-24, 20), R' = (-16, 16), and S' = (-2, 18).

Step-by-step explanation:

Recall that if a figure is dilated by a scale factor k (about the origin), then its coordinates become:

[tex](x, y) \rightarrow (kx, ky)[/tex]

In other words, we simply multiply each coordinate by the scale factor.

Triangle QRS with coordinates Q(-12, 10), R(-8, 8), and S(-1, 9) is dilated by a scale factor of two.

And we want to determine the coordinates of Triangle Q'R'S'.

Multiply each coordinate by the scale factor (two). Hence:

Q' = (-24, 20),

R' = (-16, 16), and

S' = (-2, 18).

Note: This method is only true when the figure is dilated about the origin.

Determine the value of n that makes the polynomial a perfect square trinomial. Then factor as the square of a binomial. Express numbers as integers or simplified fractions

Answers

Answer:

Step-by-step explanation:

[tex]y^2-11y+n\\=(y-(11/2))^2+n-(11/2)^2[/tex]

So in order the trinomial a perfect square we need

[tex]n-(11/2)^2 =0\\n= (11/2)^2\\n=\frac{121}{4}[/tex]

When n is equal to this number that we have

[tex]y^2-11y+n = (y- (11/2))^2[/tex]

The value of the variable n is 121/4 and the factor as the square of a binomial will be (y - 11 / 2)².

What is a perfect square trinomial?

A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.

The polynomial is given below.

⇒ y² - 11y + n

If the polynomial is a perfect square trinomial. Then the value of the variable n will be half of the square of the number.

n = (11/2)²

n = 121/4

Then the factor as the square of a binomial will be

⇒ y² - 11y + n

⇒ y² - 11y + 121 / 4

⇒ (y - 11 / 2)²

The value of the variable n is 121/4 and the factor as the square of a binomial will be (y - 11 / 2)².

Express 32% as a fraction​

Answers

Answer:

32/1

Step-by-step explanation:

Answer:

8/25

Explanation:

__________________________________________________________

Hi! I am happy to help you with this problem!!

To start we must think about what 32% is. To understand this I will make a simple problem for us to solve.

There are 100 dogs at the dog shelter. 32% of the dogs are puppies. How many dogs are puppies.

Well, this is simple! Is there are 100 dogs and 32% of them are puppies this means that 32 of them are puppies!

Lets use this what we know from the previous problem to answer your question.

You are trying to find 32% as a fraction. Because 100/100 (100%) Is equal to 1 whole, 32% must be 32/100!!

However this is not the answer. To find the final answer we have to simplify this fraction.

(32/100) / 4 = 8/25!!

This is your final answer!! I hope you found this answer helpful <3

A book is on sale for
houw 25% off. The sale
hour price is $12. What
was the original price
of the book? What
was the amount of
the discount?

Answers

If the book is 25% off, then that means you paid 75% of the original price. (100% - 25% savings)

This means $12 is 75% of the original price.
Translating this into an equation, where x is the original price:
       $12 is 75% of the original price
         12 =  0.75 •  x

So you need to solve 12 = 0.75x.

Once you find x, to figure out how much the discount was, you need to subtract 12 from the original price:
      discount = x - 12

I’ve set everything up, you just need to solve 12 = 0.75x

If f(x)=−2(x+7), then what is f(−10)?

Answers

Answer:

f(-10) = 6

Step-by-step explanation:

f(x) is simply just the name of the function. x will be your dependent variable that you'll use to plug into the equation.

Since they want you to find f(-10), you'll then plug -10 in where x was and solve.

f(-10) = -2((-10)+7)

f(-10) = -2(-3)

f(-10) = 6

Answer:

[tex]→f(x) = - 2(x + 7) \\ f( - 10) = - 2( - 10 + 7) \\ f( - 10) =( - 2) \times ( - 3) \\ \boxed{f( - 10) = 6}✓[/tex]

f(-10)=6 is the right answer.
