Use the Pythagorean theorem.

6^2 + 3^2 = c^2
36 + 9 = c^2
45 = c^2
C = sqrt45
C = 3sqrt5

3sqrt5 units

Which are the solutions of x2 = –11x + 4?

Zarrin [17]

For this case we have the following polynomial:

$x ^ 2 = -11x + 4$

Rewriting the polynomial we have:

$x ^ 2 + 11x - 4 = 0$

From here, we can solve the polynomial using the quadratic equation

We have then:

$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$

$x=\frac{-11+/-\sqrt{11^2-4(1)(-4)}}{2(1)}$

$x=\frac{-11+/-\sqrt{11^2+16}}{2}$

$x=\frac{-11+/-\sqrt{121+16}}{2}$

$x=\frac{-11+/-\sqrt{137}}{2}$

Therefore, the solutions are:

$x=\frac{-11+\sqrt{137}}{2}$

$x=\frac{-11-\sqrt{137}}{2}$

2x+4(7−x) HELP PLEASE IM DEPERATEEEEE

goldenfox [79]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{ - 2x + 28}}}}}$

Step-by-step explanation:

$\sf{2x + 4(7 - x)}$

Distribute 4 through the parentheses

$\dashrightarrow{ \sf{2x + 28 - 4x}}$

Collect like terms

$\dashrightarrow{ \sf{2x - 4x + 28}}$

$\dashrightarrow{ \sf{ - 2x + 28}}$

Hope I helped!

Best regards! :D

The first steps in writing f(x) = 4x2 + 48x + 10 in vertex form are shown. f(x) = 4(x2 + 12x) + 10 (twelve-halves) squared = 36

brilliants [131]

Answer:

$f(x)=4(x+6)^2-134$

Step-by-step explanation:

We are required to write the function $f(x) = 4x^2 + 48x + 10$ in vertex form.

First, bring the constant to the left-hand side.

$f(x) -10= 4x^2 + 48x$

Factorize the right hand side.

$f(x) -10= 4(x^2 + 12x)$

Take note of the factored term(4) and write it in the form below.

$f(x) -10+4\Box= 4(x^2 + 12x+\Box)$

$\Box = (\frac{\text{Coefficient of x}}{2} )^2\\\\\text{Coefficient of x}=12\\\\\Box = (\frac{12}{2} )^2 =6^2=36$

Substitute 36 for the boxes.

$f(x) -10+4\boxed{36}= 4(x^2 + 12x+\boxed{36})$

$f(x) -10+144= 4(x^2 + 12x+6^2)$

$f(x) +134= 4(x+6)^2\\f(x)=4(x+6)^2-134$

The function written in vertex form is $f(x)=4(x+6)^2-134$

PLEASE HURRY! The price of a wallet is $32.95 and the sales tax is 7.5%. What is the total cost of the wallet?

Fiesta28 [93]

$\frac{7.5}{100}$ x 32.95

=0.075 x 32.95 = $ 2.47

The total cost of the wallet = price of the wallet + sales tax
= 32.95 + 2.47
= 35.42
Thus, the total cost of the wallet is $35.42
