<h2>Part A</h2>

Use Pythagorean theorem to confirm the right triangle:

  • AB² + BC² = AC²
  • 12² + 5² = 13²
  • 144 + 25 = 169
  • 169 = 169

Confirmed

<h2>Part B</h2>

The triangles are similar:

  • ΔABC ~ ΔRST

Corresponding sides have same ratio:

  • AB/RS = AC/RT

Substitute known values and find the missing length:

  • 12/24 = 13/RT
  • 1/2 = 13/RT
  • RT = 13*2
  • RT = 26

PLZ PLZ PLZ PLZ HELP HELP HELP HELPFind the area of the shape.
Bingel [31]

Answer:

3.14

Step-by-step explanation:

The formula for the area of a circle is \pi r^2, where r is the radius. In this circle, the area would therefore be 3.14\cdot 2^2=12.56. However, since this is only a quarter circle, you need to divide the area by 4, meaning that the area of this shape is 3.14 square units. Hope this helps!

What is the inverse one to one function of f(x) = square root of x-2???
alexira [117]
f(x) = \sqrt{x - 2} \\y = \sqrt{x - 2} \\y^{2} = (\sqrt{x - 2})^{2} \\y^{2} = x - 2 \\x^{2} = y - 2 \\x^{2} + 2 = y \\x^{2} + 2 = f^{-1}(x)

How can you use similar triangles to solve problems?
mars1129 [50]

Answer:

you can use similar triangle to make known degrees in problems to make then easier to solve. With similar triangle, the angles are the same, but the scale is different. So by using this, one can solve both at the same time, and just just scale up the smaller one or scale down the larger, by the given/found scale.

Need help with Algebra 2! Thank you! :)
Olin [163]

Answer:

Consider the parent logarithm function f(x) = log(x)

Now,

Let us make transformations in the function f(x) to get the function g(x)

•On streching the graph of f(x) = log(x) , vertically by a factor of 3, the graph of y = 3log(x) is obtained.

•Now, shrinking the graph of y = 3log(x) horizontally by a fctor of 2 to get the grpah of y = 3log(x/2) i.e the graph of g(x)

Hence, the function g(x) after the parent function f(x) = log(x) undergoes a vertical stretch by a factor of 3, and a horizontal shrink by a factor of 2 is

g(x) = 3 log(x/2) (Option-B).

-9 more than a number results in -20
damaskus [11]

Answer:

-9+x=-20

Step-by-step explanation:

I am not so positive on this one, but if you are not doing inequalities, then this should be correct.

"More than" would insinuate that you are adding. In this class, you would have a number to replace that x, but since no number was given, you place the x in its place. x=-11, because when you "add" -9 with something to get -20, it would have to be -11. Negative numbers can be confusing because when you subtract a negative number by another negative, you end up with a negative. Like in this case. Normally, you would just put -11, so it would look like -9 - 11 = -20. But since this says "more than", unless you are doing inequalities, you add.

If you are doing inequalities, then your answer should be this:

-9 > x = -20

I hope this helps!
