Answer:

y = 12     x = 12√2     z  = 12√3

Step-by-step explanation:

The 45° triangle will also have a height of y so....

    y² + y² = x²          2y²  = x²     y² = x²/2       y = √(x²/2)

The 30°  triangle

    y² + z² = 24²                          y² = 24² - z²          y = √(24² - z²)

                               

sin 30 = y/24          1/2 = y/24      y = 12    

          y² = x²/2

         12² = x²/2²

    2(144)  = x²         x = √(288)       x = 12√2  

      y² + z² = 24²

           z² = 24² - y²

           z² = 24² - 12²

           z² = 576 - 144

            z² = 432      

                =  √(16·9·3)

            z  =  4·3√3

            z  = 12√3

     y² + z² = 24²

    12² + (12√3)² = 24²

    144 + 144·3    =   576

     2y²  = x²

     2(12)²  = x²

      288  =  (12√2)  = 144·2  = 288

Please help with this question! It’s Algebra Math 2
juin [17]

Zero of 7 with a multiplicity of 3 means one factor is (x-7)^3

Zero of -1 with a multiplicity of 2 means one factor is (x+1)^2

Zero of 5 with a multiplicity of 1 means one factor is (x-5)

Multiplying, we get

f(x) = (x-7)^3(x+1)^2(x-5)

That's already in factored form so we leave it here.

I am giving a brainliest to the best answer
arsen [322]

Answer:

A

Step-by-step explanation:

Given

f(x) = \frac{x+3}{4}

let f(x) = y and rearrange making x the subject

y = \frac{x+3}{4} ( multiply both sides by 4 )

4y = x + 3 ( subtract 3 from both sides )

4y - 3 = x

Change y back into terms of x

f^{-1}(x) = 4x - 3 → A

A bike shop sells you a bicycle for $63 and a helmet for $21. The total cost is 150% of what the shop spent originally. How much
marshall27 [118]
The bike shop made $28 dollars profit. First, you add the cost of the bike and the cost of the helmet, which is $84. Then you divide that by 150 to get what 1% would be, which is .56. Then you multiply that by 50%, which is the part of the price that the shop profited, which is $28.
