Answers

y = 192.

Step-by-step explanation:

y = k/x^3  where k is the constant of variation.

When x = 1/5 y = 375, so:

375 = k / (1/5)^3

375 = k / 1 /125

125k = 375

k = 3.

So the equation of variation is y = 3/x^3

and when x = 1/4:

y = 3 / (1/4)^3

y = 3 * 64

= 192.

x=1

Step-by-step explanation:

You just have to go through it thoroughly. You are probably making a small mistake somewhere.

we know that

if two lines are perpendicular, then the product of their slopes is equal to minus one

so

m1*m2=-1

The formula to calculate the slope between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

we have

x(-5,5)\\y(-3,-2)\\z(4,0)

Step 1

Find the slope xz

x(-5,5)\\z(4,0)

Substitute in the slope's formula

m=\frac{(0-5)}{(4+5)}

m=\frac{(-5)}{(9)}

mxz=-\frac{5}{9}

Step 2

Find the slope yz

y(-3,-2)\\z(4,0)

Substitute in the slope's formula

m=\frac{(0+2)}{(4+3)}

m=\frac{(2)}{(7)}

myz=\frac{2}{7}

Step 3

Find the slope xy

x(-5,5)\\y(-3,-2)

Substitute in the slope's formula

m=\frac{(-2-5)}{(-3+5)}

m=\frac{(-7)}{(2)}

mxy=-\frac{7}{2}

Step 4

Verify if two of the slopes are perpendicular

mxz=-\frac{5}{9}

myz=\frac{2}{7}

mxy=-\frac{7}{2}

Multiply  myz and mxy

\frac{2}{7}*-\frac{7}{2}=-1 -------> the lines segment yz and xy are perpendicular

therefore

the triangle XYZ is a right triangle    

the answer in the attached figure


40 points need  asap the coordinates of the vertices of △xyz are   x(−5,  5),   y(−3,

So the correct answer would be ( A ti no te gusta descansar.)  

Explanation:

When you say "tu" in spanish is the same as saying ( Yours don't like to rest)

so you have to use "ti" ( You don't like to rest).

Remember that "Ti"   is a personal pronoun of second person singular and is always preceded by a preposition like : Esto es para ti, Vine porti, Lo recibió de ti.

Also it doesn't have an accent mark.

BTW the sentence can also go like this :  No te gusta descansar a ti ?  both you'll be right, unless they asked for something specific.

hope that helps :D

j > 5

j > 4.5

Step-by-step explanation:

9j - 5j > 20

4j > 20

\frac{4j}{4} <u</u \frac{20}{4}

j > 5

8j > -36

\frac{8j}{8}  \frac{36}{8}

j > 4.5

Do you mean "write in slope-intercept form"?

In that case: The slope is -3/1 = -3. The y-intercept is where it crosses the y-axis, at -3. The form is y=mx+b, where m is the slope and b is the intercept, so it's y=-3x-3.

0.24 moles

Explanation: Using IDEAL GAS LAW

PV=nRT

where,

P = pressure of the gas= 2.0 atm

V = volume of the gas= 3.00L

T =Temperature of gas=25^0C=(25+273)K=298K

n = number of moles of gas=?

R = Gas constant = 0.0821 Latm/moleK

n=\frac {PV}{RT}=\frac {2.0\times 3.0}{0.0821\times 298}=0.24moles

C

Step-by-step explanation:

So we have:

\frac{6^{\frac{3}{10}}}{6^\frac{1}{5}}

To simplify, we can use the quotient rule of exponents, which says that if we have:

\frac{x^a}{x^b}

Then this equals:

=x^{a-b}

So, our equation will be:

\frac{6^{\frac{3}{10}}}{6^\frac{1}{5}}\\=6^{\frac{3}{10}-\frac{1}{5}}

Subtract the exponents. Turn 1/5 into 2/10 by multiplying both layers be 2. Thus:

6^{\frac{3}{10}-\frac{1}{5}}\\=6^{\frac{3}{10}-\frac{2}{10}}

Subtract in the exponent:

=6^{\frac{1}{10}}

So, our answer is C :)
