Triangle QRS was dilated using the dilation rule DP,4.

Point P is the center of dilation. Triangle Q R S is dilated to create triangle Q prime R prime S prime. The length of P R is 3.

What is PR'?

6 units
9 units
12 units
15 units

Answers

Using the dilation rule, the length of P'R' is: C. 12 units.

What is Dilation?Dilation, as a type of transformation, is the enlargement or reduction of a shape to create a new image which is similar to the original image.If the scale factor is a whole number, it means it's an enlargement, if fraction, it means it is a reduction.

Given that the scale factor of dilation is 4, and PR is 3.

Therefore:

P'R' = 4(PR)

P'R' = 4(3)

P'R' = 12 units.

Therefore, using the dilation rule, the length of P'R' is: C. 12 units.

[tex]x^{2} +9y^{2} =1[/tex] is an ellipse. The line y=mx+2 is tangent to the ellipse. Determine the value of ([tex]m^{2}[/tex]). Express your answer as an integer or as a common or improper fraction.

Answers

9514 1404 393

Answer:

  m^2 = 35/9

Step-by-step explanation:

The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.

  x^2 +9(mx +2)^2 = 1

  x^2 +9(m^2x^2 +4mx +4) = 1

  (9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms

__

Then the discriminant is ...

  (36m)^2 -4(9m^2 +1)(35)

We want it to be zero, so we have ...

  1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses

  36m^2 = 140 . . . . . . . . . . . . . . . add 140

  m^2 = 140/36 . . . . . . . . . . . . divide by 36

  m^2 = 35/9

The area of a rectangular garden is 8330 m².
If the length of the garden is 98 m, what is its width?

Answers

9514 1404 393

Answer:

  85 m

Step-by-step explanation:

The area is the product of length and width. This can be used to find the width.

  A = LW

  8330 m² = (98 m)W . . . . . . . . . . . fill in the given values

  8330 m²/(98 m) = W = 85 m . . . . divide by the coefficient of W

The width of the garden is 85 meters.
