Copy the problems onto your paper, mark the given and prove the statements asked. Given: marked Prove: ΔABC ≅ ΔDBC, ΔEHF ≅ ΔGHF
hjlf

The proof is given below. Please go through it.

Step-by-step explanation:

To solve Δ ABC ≅ Δ DBC

From Δ ABC and Δ DBC

AB = BD (given)

AC = CD (given)

BC is common side

By SSS condition Δ ABC ≅ Δ DBC ( proved)

To solve Δ EHF ≅ Δ GHF

Δ EHF and Δ GHF

EH = HG ( given)

∠ EFH = ∠ GFH ( each angle is 90°)

HF is common side

By RHS condition

Δ EHF ≅ Δ GHF

What is the quotient (x^3+8)/(x+2)
Citrus2011 [14]

Answer:

Step-by-step explanation:

The easiest way to do this is by using synthetic division (I really hope you know what I'm talking about!)

If the factor is x + 2 = 0, then the solution or the root is x = -2.  We will put -2 outside the "box" and the coefficients from the terms of the polynomial inside the "box":

-2|   1    0    0    8

Bring down the first number and multiply it by the -2.  Put the product up under the first 0 and add:

-2|   1    0    0    8

           -2

      1   -2  

Now multiply the -2 by the -2, put the product up under the next 0 and add:

-2|   1    0    0    8

           -2    4

      1    -2    4

Now multiply the 4 by the -2, put the product up under the 8 and add:

-2|   1    0    0    8

           -2   4    -8

     1    -2   4    0

Those bold numbers are the coefficients to the quotient, which is another polynomial, but is one degree less than the one you started with:

x² - 2x + 4 = 0

Since there is no remainder, then x = -2 is a zero of x³ + 8, and (x + 2) is a factor.

There is a whole world of stuff to learn about quadratics!!

What is the inverse of this function?​
kolbaska11 [484]

Answer:

f^{-1}(x)=4x^2-3

Step-by-step explanation:

<u>The Inverse of a Function</u>

Given a function f(x), the inverse of f, called f^{-1}(x) is a function that satisfies:

f(f^{-1}(x))=x

The domain of f becomes the range of its inverse and vice-versa.

The procedure to find the inverse of the function is:

* Write the function as a two-variable equation:

* Solve the equation for x.

* Swap the variables

We are given the function:

\displaystyle f(x)=-\frac{1}{2}\sqrt{x+3}

Defined in the interval x ≥ -3

Note f is always negative, thus its range is f(x) ≤ 0

Now we find the inverse. Call y=f(x):

\displaystyle y=-\frac{1}{2}\sqrt{x+3}

Multiplying by 2:

\displaystyle 2y=-\sqrt{x+3}

Squaring both sides:

\displaystyle 4y^2=x+3

Subtracting 3:

\displaystyle 4y^2-3=x

Swapping variables:

y=4x^2-3

Thus:

\mathbf{f^{-1}(x)=4x^2-3}

The domain of the inverse is the range of f, thus x is restricted to

x ≤ 0
