Answer:

Step-by-step explanation:

m= [ -3-(-3)] ÷ [-8-7} = 0

Therefore, the slope of the line is 0.

Now use the slope and either of the two points to find the y-intercept.

y= mx+b

-3= (0)(7)+b

b=-3

Write the equation in slope intercept form as:

y= mx+b

y= (0)x-3

y= -3

Hence, the equation of the line is y= -3.

The value of the given expression for x=1/1250is 3/5. The correct option is (G).

Given the expression is f(x)=[tex]3x^{\frac{1}{3}}[/tex].

The cube root of a number is the factor that we want multiply by itself three times to get that number. The symbol for the cube origin is 3  cube roots, the last cube root. Finding the cube root of any number is the opposite of cubing a number.

We will simplify the given expression by using substitution method and cube root.

Firstly, we will substitute x=1/125 in the given expression f(x)=[tex]3x^{\frac{1}{3}}[/tex], we get

f(x)=[tex]3\left(\frac{1}{125}\right)^{\frac{1}{3}}[/tex]

As we know that the cube root of √125 is 5.

Now, we want to simplify the above equation, we get

f(x)=3(1/5)

f(x)=3/5

Hence, the value of [tex]f(x)=3x^{\frac{1}{3}}[/tex] for x=1/125 is 3/5.

Inverse functions are those that cancel one another out. In other words, if g(x) is f's inverse, then f(g(x)) = g(f(x)) = x. (x). Given an equation for which we want the inverse, we have a fantastic method we can utilize to do this.

Not every function has a counterpart. If f(x) has an inverse, it is clear to see that it will never again have the same value. We give this resource a special name.

Inverse variation is y = k. 1/x

given y = 7

x = 3

So, 7 = k. 1/3

So, the value of k = 21

We can conclude that the value of constant variation is 21

when x = 8, the value of y will be -

y = k.1/x

y = 21 . 1/8

y = 21/8

Volume is a three-dimensional quantity that is used to measure the capacity of a solid shape. If oil flows through a pipe at a rate of 40m³/s then it takes 50mins to fill a tank of volume 1.2x10⁵m³

Volume is a three-dimensional quantity that is used to measure the capacity of a solid shape. It means the amount of three-dimensional space a closed figure can occupy is measured by its volume.

Given that Oil flows through a pipe at a rate of 40m³/s.

Volume of the tank is 1.2x10⁵m³

volume =Rate *time

Time=Volume/ Rate

Time= 1.2*10⁵m³ / 40m³=3000seconds

We need to convert time in seconds to minutes

We know that 1 hr = 60 mins.

So divide 3000 sec by 60

3000/60= 50 minutes.

Therefore 50 min it will take to fill a tank of volume 1.2x10⁵m³.

Answer:Eric cause 5/12 is greater

Step-by-step explanation:

Based on the estimated number of defective batteries and the number of batteries that were actually defective, the percent error of Jake's estimate is 20%

The percent error of a problem can be found by the formula:
= (Expected results - Actual results) / 100%

Expected results = 12 defective batteries

Actual results = 10 defective batteries

Jake's percentage error is therefore:

= (12 - 10) / 100%

= 2 / 10 x 100%

= 0.2 x 100%
= 20%

In conclusion, the percent error of Jake's estimate is 20%.

We get that an equation to represent this relationship the relation of increase in radius with respect to time as R = r + 16 t where t is the time and r is the initial radius.

We are given that, the wave travels at a rate of 16 feet / sec when George jumps off a tire swing in the circular pond.

So, this means that the radius of the wave increases by 16 feet in every second.

Now, let the initial radius be r and the radius after t seconds be R.

So, the equation will become:

R = r + 16 t

where 16 t represents the increase in radius in t seconds.

Therefore, we get that an equation to represent this relationship the relation of increase in radius with respect to time as R = r + 16 t where t is the time and r is the initial radius.

Step-by-step explanation:

the perimeter is the sum of all sides.

it is clearly a symmetric figure.

I assume the sqrt(36) is the whole baseline (incl. the left and right x).

so, we have

sqrt(8) + 2x = sqrt(36) = 6

1/2 × sqrt(8) + x = 3

sqrt(1/4 × 8) + x = 3

sqrt(2) + x = 3

x = 3 - sqrt(2)

to get the inclined sides we use Pythagoras

c² = a² + b²

c being the Hypotenuse, a and b being the legs of the right-angled triangle.

so,

side² = sqrt(8)² + (3 - sqrt(2))² = 8 + (9 - 6×sqrt(2) + 2) =

= 19 - 6×sqrt(2)

each inclined side is

sqrt(19 - 6×sqrt(2))

The difference  [tex]f^{}[/tex] between the charge for large lawns and the charge for small lawns is given by the linear equation   [tex]f^{}[/tex]  = 5H +4.40, which is D option

For small lawns the company charge is given by the linear  equation S = 23H + 15.95.

For large lawns, the company charge is given by the linear equation L = 28H + 20.35.

  [tex]f^{}[/tex]  represent the difference between the charge for large lawns and the charge for small lawns.

So, the equation can be written as   [tex]f^{}[/tex]  = (28H + 20.35) - (23H + 15.95)

this can be simplified as
 [tex]f^{}[/tex]  = 28H + 20.35 -23H - 15.95

 [tex]f^{}[/tex] = 28H- 23H + 20.35 - 15.95

For graph number 13:

We can see that the domain is: {-3, 3} the range is: R: {-4, 2} this is not a function

For a relation that maps elements x into elements y, we define the domain as the set of the inputs and the range as the set of the outputs. And we say that the relation is a function if each input is mapped into, at most, one output.

If you look at the graph 13 you can see several points, which are of the form (x, y) and are:(-3, 2), (3, 2), (-3, -4), (4, -4)And it makes a little square.

Then you can see that the inputs are -3 and 3, so the domain is:

{-3, 3}

And the outputs are 2 and -4, then the range is:

R: {-4, 2}

By solving the percent application, the result is 45% of 120 is 54 and 81 is 75% of 108.

(A) 45% of 120

Multiply 45/100 with 120 =(45/100) x 120 = (45 x120) / 100 = 54.

(B) 81 is 75%

Formula = Number x 100/Percent

             = 81 x 100/ 75 = 108

Following shows the steps on how to derive this formula and find out 75% of what number is 81. Then take 100% of that figure. Setup the equation

81/75% = Y/100%

Solve for Y

Using cross multiplication of two fractions, we get

75Y = 81 x 100

75Y = 8100

Y = 8100

100 = 108

Hence, by solving the percent application, the result is 45% of 120 is 54 and 81 is 75% of 108.
