pls help :))))))))) uhhhhhhhhh​

Given:

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.

To find:

The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.

Solution:

If a figure is dilated by factor k with origin as center of dilation, then

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

Where, 0<k<1 is reduction and k>1 is enlargement.

The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:

[tex](x,y)\to (2x,2y)[/tex]

Using this rule, we get

[tex]S(4,-2)\to S'(2(4),2(-2))[/tex]

[tex]S(4,-2)\to S'(8,-4)[/tex]

Therefore, the new coordinates of point S' are (8,-4).

Answer:

Step-by-step explanation:

now the equation looks like

3-4Cos(x)=y

hmmm i'm wondering if you can figure it out from here???  it's the same as the other two.. plug in that [tex]\sqrt{2}[/tex] /2  .. can you?   :)

Step-by-step explanation:

every output has a different input so the answer would be one

Answer:

A function is a specific type of relation in which each input value has one and only one output value. An input is the independent value, and the output value is the dependent value, as it depends on the value of the input.

Answer:

I would use multiplication

5x×5x is 25x^2, because 5 × 5 = 25, and x × x = x^2

Answer:

12

Step-by-step explanation:

The smaller triangle seems to have dilated and formed the larger triangle. So, let's find the factor of increase.

9 / 3 = 3, so 3 is the factor of increase.

Now we need to do 4 x 3 = 12

So, ? = 12

Fraction: 3/20

Decimal: 0.35

Step-by-step explanation:

a) 100% - 35% = 65

   So, 65% of the houses are NOT blue.

..............................................

Fraction: 3/20

Decimal: 0.35

Answer:

65/100 or 0.65

Step-by-step explanation:

To answer this problem all you have to do is subtract 35%.If an A+ is an 100 percent,Then subtract 100 and 35 giving you 65 percent.

But if you do not know how to turn a fraction or decimal,then i will show you.every time you have a number in the tens place,add a zero and the add the decimal and finally add 65 which making look like this:0.65.

Fraction is easy to do as long as you do a number out of 100,like this:65/100.

Answer:

w = 4.

Step-by-step explanation:

-2/5 w+11 2/5=9 4/5

-2/5w + 57/5 = 49/5

Remove the fractions by multiplying thru by 5:

-2w + 57 = 49

-2w = 49 - 57

-2w = -8

w = 4.

Answer:

w=  -8/5

2. x= 50

Answer:

Yes

Step-by-step explanation:

The only quadrilaterals with congruent diagonals are squares and rectangles and squares are technically rectangles so the answer is yes.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral can be a square or a rectangle.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

Step-by-step explanation:

Area of Circle = π × radius²

Area of Circle = 12π cm

π × radius² = 12π

radius² = 12

radius = √12

radius = 3.46

Circumference = 2 × π × radius

Circumference = 2 × π × 3.46

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we can find angle C  b/c the angles of a triangle always add to 180 , soo

180= C + 81 +63.5

35.5 = C

now that we have angle C and we know the Hyp we can use sin to find side g

where g = Opp and Hpy = 13.8 for this question

Sin(35.5) = Opp / 13.8

13.8*Sin(35.5) = Opp

8.0137 = Opp

g = 8.0137

next they ask for the area of the biggest triangle  ABC ( there are two smaller ones when you use D )

we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.  

we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj

Cos(35.5) = Adj / 13.8

13.8*Cos(35.5) = Adj

11.234794 =Adj

now solve for DB using cos again but with the other smaller triangle where  Adj = DB now

Cos(63.5) = Adj / 8.9

8.9*Cos(63.5) = Adj

3.971160

add these two Adjs together to get the total  'a' side

15.205954

now plug in side a as the base and g as the height of our biggest triangle

Area = 1/2 * 15.205954 * 8.0137

Area = 60.9159

rounded to 2 sig figs

Area = 60.92   :)   hope you get an "A"    :P

Answer:

1/7

Step-by-step explanation:

Given that :

Line AB contains points A (8, −4) and B (1, −5)

Slope = Rise / Run

Rise = y2 - y1 = - 5 - (-4) = - 5 + 4 = - 1

Run = x2 - x1 = 1 - 8 = - 7

Slope = Rise / Run = - 1 / - 7

Slope = 1/7
