Answer 1

Answer:

1

Step-by-step explanation:

Using the rules of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

Given

[tex](\frac{1}{x^{(a-b)}) } ^{a+b}[/tex] × [tex](\frac{1}{x^{b+a}) } ^{b-a}[/tex]

= [tex]\frac{1}{x^{(a-b)(a+b)} }[/tex] × [tex]\frac{1}{x^{(b+a)(b-a)} }[/tex]

= [tex]\frac{1}{x^{(a^2-b^2)} }[/tex] × [tex]\frac{1}{x^{(b^2-a^2)} }[/tex]

= [tex]\frac{1}{x^{(a^2-b^2+b^2-a^2)} }[/tex]

= [tex]\frac{1}{x^{0} }[/tex]

= [tex]\frac{1}{1}[/tex]

= 1

A shelter has 5 dogs for every 4.cats. How many cats will the shelter have if they have 25 dogs?

Answers

Answer:

20 cats

Step-by-step explanation:

A proportion has to be setup to answer this

5/4 = 25/x

x represents the missing number of cats

This fraction represents the relationship amongst dogs and cats

----

To solve cross multiply

5x = 100

(let me down below if you need an explanation on how to cross multiply)

Divide both sides by 5 in order to get the variable by itself

100/5 = 20

x = 20

The shelter has 20 cats

The shelter will have 20 cats. If the shelter has five dogs for every four cats,then every five dogs that are added into the shelter four cats will be added.

5x + 2y = 12
5x – 2y = 28

Answers

Answer:

x=4 y=-4

Step-by-step explanation:

Step: Solve5x+2y=12for x:

5x+2y=12

5x+2y+−2y=12+−2y(Add -2y to both sides)

5x/5=−2y+12/5

x= −2/5y+12/5

−2/5y+12/5 for x in5x−2y=28

5(−2/5y+12/5)−2y=28

−4y+12=28(Simplify both sides of the equation)

−4y+12+−12=28+−12(Add -12 to both sides)

−4y=16

−4y/−4=16/−4

(Divide both sides by -4)

y=−4

Substitute −4 for y in x=−2/5y+12/5

x= −2/5y+12/5

x=−2/5(−4)+12/5

x=4

The volume of a cylinder is 4πx3 cubic units and its height is x units. Which expression represents the radius of the cylinder, in units? 2x 4x 2πx2 4πx2

Answers

Answer:

It's A

Step-by-step explanation:

The expression that represents the radius of the cylinder is 2x

What is volume?

The volume of a shape (e.g. cylinder) is the amount of space in the shape i.e. the cylinder

Below, is how to calculate the radius of the cylinder

The volume is given as:

V = 4πx³

The volume of a cylinder is:

V = πr²x

By comparison, we have:

πr²x = 4πx³

Divide the common factors

r² = 4x²

Take the square root of both sides

r = 2x

Hence, the expression that represents the radius of the cylinder is 2x

Derrick is placing a right triangle in the coordinate plane. He knows that the longer leg is 3 times the length of the shorter leg. He places the longer leg on the x-axis.

What coordinates should he assign to the third vertex of the triangle?

Answers

Answer:

Longer leg is placed on X axis.

Let the longer leg be at A(0,0) and B(3 a,0),or (-3 a,0), which is  either base or altitude.

AB= 3 a

As longer leg = 3 × shorter leg

Shorter leg should be placed  either at (0,a) or (0,-a) maintaining triangle as right angled triangle.
