Triangle ABC is to be dilated through point P with a scale factor of 3. How many units away from point A along ray PA will A’ be

kakasveta [241]

Answer:

Point A' will be located 10 units away from point A along ray PA

Step-by-step explanation:

we have

The scale factor is 3

step 1

Find out the distance PA'

we know that

The distance PA' is equal to multiply the distance PA by the scale factor

$PA'=PA*3$

we have

$PA=5\ units$

substitute the given values

$PA'=(5)*3=15\ units$

step 2

Find out how many units away from point A along ray PA will A’ be located

we know that

$PA'=PA+AA'$

we have

$PA=5\ units$

$PA'=15\ units$

substitute the given values and solve for AA'

$15=5+AA'$

$AA'=15-5=10\ units$

therefore

Point A' will be located 10 units away from point A along ray PA

The equation y2/100+x2/4 =1 represents an ellipse. Which points are the vertices of the ellipse? (−10, 0) and (10, 0) (−2, 0) an

mina [271]

Answer:

see explanation

Step-by-step explanation:

For the ellipse

$\frac{x^2}{a^2}$ + $\frac{y^2}{b^2}$ = 1

Then the vertices are (a, 0), (- a, 0) and (0, b), (0, - b)

Given

$\frac{y^2}{100}$ + $\frac{x^2}{4}$ = 1

Then

a² = 4 ⇒ a = 2 and b² = 100 ⇒ b = 10

Hence the vertices are

(2, 0), (- 2, 0) and (0, 10), (0, - 10)
