Answers

Answer:

10,000

Step-by-step explanation:

500/0.05= 10,000

You take the amount you are given divided by the decimal form of the percentage you are given to find the answer.  It's a reverse from the way you find 5% of 10,000.

0.05=5%

Find sin A, cos A, and tan A as
a fraction in simplest form.

Answers

Answer:

sin A = [tex]\frac{15}{17}[/tex]

cos A = [tex]\frac{8}{17}[/tex]

tan A = [tex]1\frac{7}{8}[/tex]

Step-by-step explanation:

sine = [tex]\frac{ooposite}{hypothenuse}[/tex]

sine A = [tex]\frac{15}{17}[/tex]

cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]

cos A = [tex]\frac{8}{17}[/tex]

tan = [tex]\frac{opposite}{adjacent}[/tex]

tan A = [tex]\frac{15}{8} = 1\frac{7}{8}[/tex]

[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

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.
