I would love to help you :)

So what do we know?:

We know that side A has a length of 25, and side B has a length of 21.

So that leaves us to find the length of side C correct?

Answer

Tbh I'm to lazy to explain how I got this and its mostly likely incorrect. but I think the answer is

4

(most likely incorrect LOL)

Since it is a right triangle, you can use the Pythagorean Theorem to find the length of the missing side.
a^2 + b^2 = c^2
(a and b are the legs, c is the hypotenuse)
In this triangle, a=21 and c=25. Find b.
21^2 + b^2 = 25^2
441 + b^2 = 625
b^2 = 184
b = 13.6

The ratio of white flour to whole wheat flour in a bread recipe is 2:3. The recipe uses 10 cups of flour. How much of each type
lesantik [10]
This means that 2/5 is white and 3/5 is whole wheat, so 2/5 of 10=4 cups of white, 3/5 of 10=6 cups of whole wheat.

Answer:

<h3>numbers of Ostrich he keep = 725</h3>

<u>Step-by-step explanation:</u>

  • Area of field = 30 × 155 + 90 × 45
  • Area of field = 4650 + 4050
  • Area of field = 8700 m²

  • 1 ostrich need = 12 m²

numbers of Ostrich = 8700 ÷ 12

numbers of Ostrich = 725

The parent function f(x)=x^2 is translated such that the function g(x)=-x^2+6x-5 represented the new function. What is true abou
Alla [95]
<h3>Answer:</h3>
  • g(x) has an axis of symmetry at x = 3
  • g(x) is shifted right 3 units from the graph of f(x)
  • g(x) is shifted up 4 units from the graph of f(x)
<h3>Step-by-step explanation:</h3>

The vertex form of g(x) is ...

... g(x) = -(x -3)² +4

This is offset to the right by 3 and up by 4 from the parent function. (It is also first reflected across the x-axis.)

_____

<em>Vertex form</em>

You know the leading coefficient is -1 because that's what it is for x² in the given form. When you factor -1 from the first two terms, of the given form, you have ...

... g(x) = -1(x² -6x) -5

Half the x coefficient inside parentheses will be the constant in the squared binomial term, so that term is (x -3)². The constant in that square is +9, so adding that value inside and outside parentheses in g(x) gives ...

... g(x) = -1(x² -6x +9) -5 +9

... g(x) = -(x -3)² +4 . . . . . vertex form

_____

<em>About transformations</em>

g(x) = f(x -a) causes the graph of f(x) to be shifted "a" units to the right. For a function f(x) with an axis of symmetry at x=0, it moves the axis of symmetry to x=a.

g(x) = f(x) +a causes the graph of f(x) to be shifted "a" units up.

g(x) = -f(x) causes the graph of f(x) to be reflected across the x-axis.

Here, we have all three of these transformations. First is the reflection:

... f₁(x) = -f(x) = -x²

Then we have shifting to the right 3 units. (also moves the axis of symmetry)

... f₂(x) = f₁(x-3) = -(x -3)²

Finally, we have shifting up 4 units.

... g(x) = f₂(x) +4 = -(x -3)² +4
