We can use the table to evaluate the compositions of the functions, we will get:

Here we have a table for functions f(x) and g(x), and we want to use that table to evaluate the compositions of the functions.

First, we want to get f(g(6))

Using the table, we can see that g(6) = 0, then:

f(g(6)) = f(0)

And using the table we can see that f(0) = 3, then:

f(g(6)) = 3

The second composition is:

g(f(0))

We know that f(0) = 3

g(f(0)) = g(3)

And using the table g(3)=  8, then:

g(f(0)) = 8

The third one is:

f(f(4))

We can see that f(4) = 7

So: f(f(4)) = f(7)

And again, you can find f(7) on the table to see that f(7) = 4

Then:

f(f(4)) = 4

y = 6(2)^(x-4)-1 is an exponential function with a base of 2 and an exponent of x-4. The coefficient of the base, 6, is called the leading coefficient. The constant term, -1, is the y-intercept, the point where the graph of the function crosses the y-axis. The function is also a shifted version of the basic exponential function y= a*b^x, where a is the leading coefficient and b is the base of the function.

Since the base of the function is 2, the graph of the function will increase or decrease at an increasing rate. The leading coefficient of 6 will affect the steepness of the graph, making it steeper than the basic exponential function y=2^x. The horizontal shift of the graph is 4 units to the left, as the exponent has x-4 instead of x.

In terms of symmetry, the graph of this function has no symmetry.

The function has no rotational symmetry because it is not repeated after any rotation around the origin.

Degree: 2

Leading coefficient: -1 (The leading coefficient is the coefficient of the term with the highest degree in the polynomial, in this case, the coefficient of u², which is -1)

Step-by-step explanation:

First, let's make the first number y and the second number x

Next, we write our equations which are y=1/2x+3 and y=1/4x+5

Then, we set those two equations equal to each other and then solve for x

The first step of the equation is to add/subtract like terms, I subtracted 5 on each side of the equation, our new equation is 1/4x=1/2x-2, I then subtracted 1/2x on each side so now our equation is -1/4x=-2. We then multiply 1/4 by its reciprocal on each side. Its reciprocal is -4.

Now that we know x is equal to 8 now we can fill x into the original equations which were y=1/2x+3 and y=1/4x+5 you don't have to solve both, just one of your choosing.

The Z-score is (b) -1.64.

Z-score is a statistical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score. A Z-score of 1.0 would indicate a value that is one standard deviation from the mean. Z-scores may be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean.

To find the z-score corresponding to an observation of 4.7, we can use the formula:

z = (x - mu) / sigma

where x is the observation, mu is the mean, and sigma is the standard deviation.

Given that X-N(5.7, 0.61) we can substitute

z = (4.7 - 5.7) / 0.61 = -1.64

Therefore ,on solving the provided question we can say that - Simple Interest after 5 year the car value is £7,689.6

Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it.

here,

rate = 10%

Time = 1 year

Principle = 12000

=>SI = PRT/100

=> SI =  10*1*12000/100

=> SI = 1200

and

=>  After 1 year = 12000 -1200 = 10800

and

for five  years

=> SI = PRT/100

=> SI = 10800 * 7.2 * 4 / 100

=> SI = 3110.4

After 5 year = 10800 - 3110.4  = 7,689.6

Answer is 60 % is the percentage of boys studying German .

So, for this one, you must first determine the number of French students.

Simple method:

[tex]\frac{1}{9}[/tex]  is 270 divided by 9, which equals 30, hence  [tex]\frac{2}{9}[/tex]of 270 is 60. The result of multiplying [tex]\frac{1}{9}[/tex] by 2 to get [tex]\frac{2}{9}[/tex] is 60.

French is being studied by 60.

When you apply this to the French to Spanish ratio of 3:7, you get 3 and 60 on the same side. In order to get to 60, you must multiply 3 by 20. (or divide 60 by 20 to get 3).

Therefore, 20 is the number you use to apply the same formula to the other side of the ratio.

To reach 140, multiply 7 by 20 (or 7 by 10, then multiply that number by 2).

Spanish is being studied by 140.

After subtracting the French and Spanish from the overall number, you are left with 70 German speakers at 270-140-60.

42 of these 70 are males. 28 females are produced by 70-42. The percentage of males studying German is [tex]\frac{42}{70}[/tex]. This is equivalent to [tex]\frac{6}{10}[/tex], and you multiply a fraction by 10 to convert it to a percentage ([tex]\frac{60}{100}[/tex] in this case).

Additionally, 60% is equal to [tex]\frac{60}{100}[/tex]  .

Your response is thus 60%.

The direction of the ball at this point is <1/8, -4, 96/8>

The position vector of the ball can be found by taking the derivative of the rectangular equation with respect to time:

r(t) = <8t, -16t², 32t³>

To find the speed of the ball at the point where it has traveled 64 feet horizontally, we can use the magnitude of the velocity vector, which is the derivative of the position vector with respect to time:

v(t) = <8, -32t, 96t²>

|v(t)| =√(8² + (-32t)² + 96t⁴) = 8*√(1 + t² + 3t⁴)

We need to find the time t at which the ball has traveled 64 feet horizontally. We know that x = 8t, so we can set x = 64 and solve for t:

8t = 64

t = 8

At t = 8, the speed of the ball is:

|v(8)| = 8√(1 + 8² + 3(8⁴)) = 8√(65) = 8*8 = 64

To find the direction of the ball at this point, we can use the unit vector of the velocity vector:

v(t) = <8, -32t, 96t²> / |v(t)|

v(8) = <8, -256, 6144> / 64 = <1/8, -4, 96/8>

Answer:

f(x) = - [tex]\frac{1}{2}[/tex] x - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

the equation of a line in slope- intercept form is

f(x) = mx + c ( m is the slope and c the y- intercept )

given f(- 5) = 2, that is when x = - 5 , y = 2

f(7) = - 4, that is x = 7, y = - 4

the 2points (- 5, 2 ) and (7, - 4 ) lie on the line

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, 2 ) and (x₂, y₂ ) = (7, - 4 )

m = [tex]\frac{-4-2}{7-(-5)}[/tex] = [tex]\frac{-6}{7+5}[/tex] = [tex]\frac{-6}{12}[/tex] = - [tex]\frac{1}{2}[/tex] , then

f(x) = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation of the line

to find c substitute either of the 2 points into the partial equation

using (- 5, 2 ) , then

2 = - [tex]\frac{1}{2}[/tex] (- 5) + c = [tex]\frac{5}{2}[/tex] + c ( subtract [tex]\frac{5}{2}[/tex] from both sides )

Answer:

We know that Keilantra has $660 to spend, she has already spent $488.20 on a bicycle, $11.17 on two reflectors and $19.05 on a pair of gloves.

We can represent the amount spent on reflectors as 2 * $11.17 = $22.34

So the total amount spent so far is:

$488.20 + $22.34 + $19.05 = $529.59

We can represent the remaining amount of money she has to spend on outfits as:

$660 - $529.59 = $130.41

We can use this remaining amount to find out the number of outfits she can purchase by dividing the remaining amount by the cost of each outfit:

$130.41 / $37.26 = 3.5

The inequality that represents this situation is:

x <= 3.5

Answer:

Let's call the number of hours it takes to fill the pool "h".

We know that the initial amount of water in the pool is 640 gallons, and water is being added at a rate of 320 gallons per hour. To find out how many hours it will take to fill the pool to 1600 gallons, we can set up the following equation:

640 + (320h) = 1600

To solve for h, we'll subtract 640 from both sides of the equation:

320h = 960

Then divide both sides by 320:

h = 3

So it will take 3 hours to fill the pool with water.

It will take 3 hours to fill the pool.

Amount of water that can fit in the pool= 1600 gallons.

The amount of water already present= 640 gallons.

Therefore, the amount of water required to fill the pool= 1600-640 = 960 gallons

The rate at which the water is being pumped= 320 gallons/ hour

Therefore, the time needed to fill the pool= the quantity to be supplied/ the rate at which the water is being pumped

=> 960/ 320

=> 3 hours.

Therefore, the time required to fill the pool completely is 3 hours.
