If the vertex H of a triangle is at (- 2, 2) , what are the coordinates of H in the dilation of the triangle when the origin is

the center of dilation and the scale factor is 3?
Mathematics

uysha [10]3 years ago

Answer:

The coordinates of H after the dilation is (-6,6)

Step-by-step explanation:

Here, we want to get the coordinates of the image given the coordinates of the pre-image

with the dilation factor and the coordinates, what we have to do is to simply multiply each of the coordinates of the point on the vertex by 3

Mathematically, we have this as;

H’ = 3H

so;

(-2,2) becomes; (3 * -2, 3 * 2) = (-6,6)

3) Solve these problems that have more than one answer.
MaRussiya [10]

Answer:

225

Step-by-step explanation:

Mary = 3x (3 times Carey)

Carey = x

Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)

3x + x + x/2 = 405

4x + x/2 = 405

8x/2 + x/2 (treat these as fractions) = 405

9x/2 = 405

9x = 810 (cross multiply)

x = 90

Mary = 3(90)      270

Carey =              90

Barry = 90/2      45

Mary - Barry

270 - 45 = 225

Hope this helps! :)

The ordered pairs (2, 20) and (3, 40) are solutions to an exponential function. Write the equation for this function.
weeeeeb [17]

Answer:

The exponential function will be  f(x) = 5(2)^{x}

Step-by-step explanation:

Let the exponential function is given by f(x) = a(b)^{x} ............ (1)

Now, ordered pairs (2,20) and (3,40) are the solution of the above exponential function. So, they will satisfy the equation.

Now, for the ordered pair (2,20) putting f(2) = 20, we get

20 = a(b)^{2} ............. (2)

Again, for the ordered pair (3,40) putting f(3) = 40, we get

40 = a(b)^{3} ............. (3)

Now, from equations (3) and equation (2) we get,

2 = b

⇒ b = 2.

Now, from equation (2) we get, 20 = a(2)^{2} = 4a

⇒ a = 5

Therefore, the exponential function will be

f(x) = 5(2)^{x} (Answer)

Find the height and area of each of these triangles ​
andreev551 [17]

Answer:

area= 1/2*(h*b) h- height, b- base

the triangle is isosceles (denoted by the 2 dashes on the sides of the triangle)

so they are equal in length

angles in triangle = 180

so 38+38=76

180-76=104

base=24

divide the triangle in the center

so now triangle 1(left) the base = 12

and triangle 2(right) the base = 12

use trigonometric ratios

in this we need to find the height

which is opposite of 38,

we already have the adjacent =12

so the ratio is Tan (Tangent Opposite/Adjacent)(TOA)

Tan38= (12/h)

multiply by h

h*Tan38=12

h=12/tan38 = 15.35929959

Which of the following is the definition for permutation?
Kamila [148]

Answer:

The answer is D. Selections of objects in which the order of the objects matters.

Step-by-step explanation:

Permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement.

The formula for permutation: A permutation is the choice of (r) things from a set of (n) things without replacement and where the order matters. Formula-  

nPr= \frac{n!}{(n-r)!}

Permutation can be classified in three different categories:

  • Permutation of (n) different objects (when repetition is not allowed)
  • Repetition, where repetition is allowed
  • Permutation when the objects are not distinct (Permutation of multi sets)
