(x's are variables not multiplication) (dashes resemble fractions) (^ resembles powers)

Answers

Answer 1

The equivalent expression to the given one is  x^8/(9*y^10)

So the correct option is B.

Which expression is equivalent to (3x^−4y^5) ^−2?

Here we just need to operate with the exponent properties that we know and love.

Remember that:

(a^n)^m = a^(n*m)

Then if we apply that to our case we will get:

(3x^−4y^5) ^−2 = (3^(-2)*x^(-4*-2)*y^(5*-2))

                         = (3^(-2)*x^8*y^(-10)

Now remember that negative exponents just "move" the number to the denominator position, this means that:

3^-2 = 1/3^2 = 1/9

Then we can rewrite our expression as:

(3^(-2)*x^8*y^(-10) = x^8/(9*y^10)

That is the equivalent expression to the given one.

The correct option is B.

Let g be a reflection in the x-axis and a vertical stretch by a factor of 3, followed by a translation 4 units down and 1 unit right of the graph of f(x)=|x|

Answers

g(x) = -3|x-1| - 4

Kudi and Ladi share 20 oranges in the ratio 2 is to 3 how many oranges has Ladi​

Answers

Answer:

12 oranges

Step-by-step explanation:

The ratio is K/L where K = Kudi's oranges and L = Ludi's oranges

K/L = 2/3

To find the number of oranges that Kudi has, divide the numerator by the sum of numerator and denominator.Then multiply by total number of oranges

For Ladi, divide the denominator by the sum of numerator and denominator. Then multiply by total number of oranges

[tex]K = 20\cdot \dfrac{2}{2+3} = 20 \cdot \dfrac{2}{5} = 8 \; \mathrm {oranges}\\\\L = 20\cdot \dfrac{3}{2+3} = 20 \cdot \dfrac{3}{5} = 12 \; \mathrm {oranges}[/tex]

If f(x) and its inverse function, f superscript negative 1 baseline (x), are both plotted on the same coordinate plane, where is their point of intersection? (0, 6) (1, 4) (2, 2) (3, 0)

Answers

The point of intersection for the function is  (2, 2)

Considering to the line passing through the points (0,6) and (3,0)  to be f(x).Therefore the slope intercept of the function is

m = 0-6/3-0 = -2

So, the functions F(x) in the slope-intercept form f(x)= -2x+6  ......1

interchanging the variable x to y and y to  x

=> x =-2y + 6

=> 2y = -x + 6

=> y= -0.5x + 3

let  f⁻¹(x)= y

f⁻¹(x) =-0.5x+3   ......2

Solving the equation  1 and 2, we get

=> -0.5x + 3 = -2x + 6

=> 2x - 0.5x = 6 - 3

=> 1.5x = 3

=> x = 2

Substituting the values of x in the function  we get,

f( x) = -2(2) + 6 = 2

Thus, the outcome is (2,2)

three boys have a total of 24 apples. the littlest boy has 2 times more than the second boy. the second boy has 2 less than the first boy. how much has all the boys

Answers

Each boy has apples respectively 11, 5½,7½

There are total 24 apples.
We have to find that how many Apples each boy have .
Littlest boy have 2 times more than the second boy.
And second boy has 2 less than first boy .
First we have to calculate equation for that .
Littlest boy have 2 times the the second boy.
Let littlest boy have apples = x
So, second boy have apples = x/2
Now, here it is given that,
Second boy has 2 less than first boy .
So, first boy has apples = (x/2)+2
Now sum of all apples = 24.
So, we have to add all equations to find the value of x .
x+x/2+(x/2)+2= 24. [X/2+x/2= x]
x+x+2=24
2x=22
x=11.
So, little boy has 11 apples.
Second boy has apples = x/2
=11/2= 5½
Second boy has 5 and ½ apples .
First boy has apples= (x/2)+2
= x/2)+2 = 5½+2= 7½
So, the first boy has 7 and ½ apples .

In order to find the fifth term, for example, we need to plug n = 6

And angles c and b are across from each other so they’re vertical; subsequently, they’re congruent as well.

Thus, both b and c are 71 degrees.
When lines intersect they formed angles. angles are the spaces or shapes form between intersecting lines. In this problem they want us to find the angles c and b.

In this problem are two lines which intersect, this intersection creates 4 angles.

Answer: Angles B and C are 71 degrees.

Step by step explanation: Angles b and c are vertical angles, therefore they will be the same amount. One of the angles is given, which is 109. Knowing that a straight angles is 180 degrees, we can subtract 180 from 109 to get the answer.

180-109= 72 degrees.
You can double check by adding 72 to 109, which gives you 180.

Answers

The measures of the indicated angles are

m ∠EFH = 59.5°

m ∠GFH = 59.5°

Calculating angles

From the question, we are to determine measures of the indicated angles

The angles are ∠EFH and ∠GFH

From the given information,

FH bisects ∠EFG

Since FH bisects ∠EFG,

Then,

m ∠EFH  = m ∠GFH

and

m ∠EFH  + m ∠GFH = m ∠EFG

Then,

We can write that

m ∠EFH  + m ∠EFH = m ∠EFG

2 × m ∠EFH = m ∠EFG

2 × m ∠EFH = 119°

m ∠EFH = 119°/2

m ∠EFH = 59.5°

Thus,

m ∠GFH = 59.5°

Hence, the measures of the indicated angles are

m ∠EFH = 59.5°

Answers

According to the given statement

The area of Colorado is 67.43 times greater than the area of Rhode Island

Define Area?

Area is typically thought of as a specific instance of volume for two-dimensional regions. By applying axioms, one can define area as the relationship between a set of real numbers and a collection of particular plane figures.

Area is a mathematical concept that describes the size of a region on a planar or curved surface. The area of an open surface or the border of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

According to the given values;

The area of Rhode Island = 43.07 billion square feet.

The area of Colorado = 2.9045 trillion square feet.

43.07 billion =43,070,000,000

2.945 trillion =2,9045,000,000,00

Now we have to find how many times as great is the area of Colorado than the area of Rhode Island.

For this ,we divide area of Colorado by area of Rhode Island.

=2,9045,000,000,00/43,070,000,000

=67.43

So, the area of Colorado is 67.43 times greater than the area of Rhode Island.

value of the function for an input of 50, and what does it represent?

Answers

The value of the function at an input of 50 will be 36.95.

How to calculate the value?

Since the pressure at the surface is 14.7 psi, a function to represent water pressure will be:

= 14.7 + (0.445 × p)

where p is the increase in pressure for each foot

= 14.7 + 0.445p

Therefore when the input is 50, the amount will be:

= 14.7 + 0.445p

= 14.7 + 0.445(50)

= 14.7 + 22.25
