the cost of the women's haircut is $15 and to shampoo the woman's hair is $5

and the cost of the mens hair cut is $7 and to shampoo the mens hair is $2

15+5=$20 is how much it cost for the women.

7+2=$9 is how much it cost for the men.

Answer:

Step-by-step explanation:

it's an isosceles right ∆.

so (9√2)^2 = 81*2= 162 = 2s^2

let x=y=s

s^2 = 81

s = 9

Describe the sequence of transformations that would take the graph of f(x)=x² to each parabola described below. Focus: (1/4,0),d

ser-zykov [4K]

Answer:

The parabola obtained is x=y²

Step-by-step explanation:

Given the focus (1/4,0) and directrix: x=-1/4

A point on the parabola is determined by the distance of that point with the focus and with the directrix:

Distance between the parabola and the directrix: $\sqrt{(x+\frac{1}{4})^{2} }$

Distance between the parabola and the focus: $\sqrt{(x-\frac{1}{4})^{2} +(y-0)^{2} }$

$\sqrt{(x+\frac{1}{4})^{2}}$ = $\sqrt{(x-\frac{1}{4})^{2} +(y-0)^{2} }$

$(x+\frac{1}{4})^{2}$ = $(x-\frac{1}{4})^{2} +(y-0)^{2}$

$x^2+\frac{1}{2} x+\frac{1}{16} = x^2-\frac{1}{2} x+\frac{1}{16} + y^{2}$

$\frac{1}{2} x=-\frac{1}{2} x + y^{2}$

$\frac{1}{2} x+\frac{1}{2} x = y^{2}$

x=y²

Rewrite the expression with rational exponents as a radical expression by extending the properties of integer exponents.

arlik [135]

Answer:

$\sqrt[4]{2}$

Step-by-step explanation:

We start with the original problem:

$\frac{2^{3/4}}{2^{1/2}}$

So first we start by applying the quotient rule for powers, which tells you that whenever you are dividing two powers that have the same base and different power, you can copy the base and subtract the powers:

$\frac{b^{a}}{b^{c}}=b^{a-c}$

so:

$\frac{2^{3/4}}{2^{1/2}}=2^{\frac{3}{4}-\frac{1}{2}}$

which yields:

$2^{\frac{1}{4}}$

since we are talking about a rational exponent, we can next turn it into a radical by using the following rule:

$b^{\frac{1}{a}}=\sqrt[a]{b}$

so:

$2^{\frac{1}{4}}=\sqrt[4]{2}$
