We are given function f(a) = 1.07a for total amount including sales tax.

g(b) = b+50 total cost including delivery.

We need to write function g(f(a)).

g(f(a)) = g of f(a).

We need to substitute function f(a) in g(b) function for b.

g(f(a)) = g(1.07a) = 1.07a +50.

We are given mattress price a = $1125.

In order to find the total cost including delivery charges, we need to plug a= 1125 in the above function 1.07a +50.

Plugging a= $1125, we get

g(1125) = 1.07a +50 = 1.07*1125 +50 = 1203.75 +50 = 1253.75.

Answer:

g(f(a)) = 1.07a +50.

Total cost including delivery charges is $1253.75.

First, we need to solve the equation 4x+5y=7 to make it slope intercept form and find the slope of the line, because parallel lines have the same slope.

4x+5y=7

Subtract 4x from both sides.

5y=-4x+7

Divide both sides by 5.

y=-4/5x+7/5

The slope of the line is -4/5x. Plug that in to the blank slope intercept form equation, y=mx+b, with m being the slope and b being the y-intercept.

y=-4/5x+b

Now, we need to solve for the y-intercept. We can do this by plugging in the given coordinates (4,-3) into the above equation for x and y respectively:

-3=-4/5(4)+b

-3=-16/5+b

Add -16/5 to both sides.

1/5=b

The y-intercept is 1/5, plug this into the equation:

[tex]y=-\frac{4}{5}x+\frac{1}{5}[/tex]

Your equation is the above equation.

I hope this helps :)

Final answer:

To find the slope-intercept form of a line parallel to 4x + 5y = 7 and passing through (4, -3), first find the slope of the given line, then use the point-slope form with the given point to derive the final slope-intercept form, which is y = (-4/5)x + 1/5.

Explanation:

The student is asking for the slope-intercept equation of a line parallel to another line. Since parallel lines have the same slope, we first need to find the slope of the given line, 4x + 5y = 7. To do this, we solve for y to get it into the slope-intercept form, y = mx + b, where m is the slope.

To convert 4x + 5y = 7 into slope-intercept form, we subtract 4x from both sides to get 5y = -4x + 7, and then divide by 5, resulting in y = (-4/5)x + 7/5. The slope of this line is -4/5. Hence, our new line must have the same slope of -4/5 to be parallel.

We use the point-slope form of the equation, which is y - y1 = m(x - x1), to get the equation of the line passing through the point (4, -3). Plugging in the values, we have y - (-3) = (-4/5)(x - 4), which simplifies to y + 3 = (-4/5)x + 16/5. To get the slope-intercept form, we subtract 3 from each side and get y = (-4/5)x + 16/5 - 15/5, leading to y = (-4/5)x + 1/5.

To find the price per pound, simply add 0.65 + 0.75 then divide.

0.65 + 0.75 = 1.40    13.65 / 1.40 = 9.75

Danny paid $9.75 per pound!

Lets go through the steps

1) Add the weights together which gives us 1.4 lb

2) Divide the cost by the weight 13.65/1.4 = $9.75 lb

the vertex of the quadratic function

[tex]f(x)= \frac{1}{2}x^2+3x+\frac{3}{2}[/tex]

To find vertex we use formula x= -b/2a

from the given equation , a= 1/2  and b = 3

Now we plug in the values in the formula

[tex]x = \frac{-b}{2a}[/tex]

[tex]x= \frac{-3}{2\frac{1}{2}}=-3[/tex]

x coordinate of vertex is -3

Now plug in -3 for x  in f(x)

[tex]f(-3)= \frac{1}{2}(-3)^2+3(-3)+\frac{3}{2}[/tex]

f(-3) = -3

the y coordinate of vertex is -3

So vertex is (-3,-3)

Answer:

(-3, -3)

Step-by-step explanation:

The standard form of a quadratic equation is [tex]y = ax^2+bx+c[/tex] where the coordinates of the highest point (x, y) indicate the vertex.

Here, [tex]a= \frac{1}{2} , b = 3[/tex] and  [tex]c= \frac{3}{2}[/tex].

We know the formula to find the x coordinate = [tex]\frac{-b}{2a}[/tex]

[tex]x= \frac{-3}{2(\frac{1}{2}) }[/tex] = [tex]-3[/tex]

To find y, put this value of x in the function to get:

[tex]y = \frac{1}{2} x^2+3x+\frac{3}{2}[/tex]

[tex]y = \frac{1}{2} (-3)^2+3(-3)+\frac{3}{2}[/tex]

[tex]y = -3[/tex]

Therefore, the vertex (x, y) = (-3, -3)

The equation of the line that is parallel to y = -x + 9 and passes through the point (7, -13) is y = -x - 6.

Now, we want to find the equation of a line that is parallel to this given line and passes through the point (7, -13). Since the new line is parallel, it will have the same slope of -1. Let's denote the equation of the new line as y = mx + b. We know the slope (m = -1), and we have a point (7, -13) that the line passes through. We can use this information to find the value of b.

To find b, we can plug in the coordinates of the point (7, -13) into the equation y = -x + b:

-13 = -1 * 7 + b

Now, solve for b:

b = -13 + 7

b = -6

Therefore, the value of b is -6.

Final answer:

0.8 divided by 0.6 is 1.33333... which, when rounded to the nearest hundredth, is 1.33. The rounding should be done to the nearest hundredth as 'rounding to the nearest hundred' typically does not apply to decimals.

Explanation:

To calculate 0.8 divided by 0.6, we simply perform the division:

0.8 ÷ 0.6 = 1.33333...

When we round this to the nearest hundredth, we look at the third decimal place. Since it's 3, we do not round up the second decimal place. Thus, 1.33333... rounded to the nearest hundredth is 1.33.

Rounding numbers and understanding division are fundamental skills in mathematics. They are essential for various applications, such as converting fractions to percentages or when dealing with metrics and customary units.

However, the question asked to round to the nearest hundred, which seems to be a typographical mistake, because we usually round numbers to the nearest hundredth or to the nearest hundred as a whole number, but not to the nearest hundred as a decimal. Assuming it's a typo and meant the hundredth, the result is 1.33. Otherwise, 1.33 rounded to the nearest hundred as a whole number is simply 100 (since this is the closest hundred to 1.33).

To earn his desired $5000, Chip must sell 50 products per month. Firstly, his desired income minus his base salary is calculated this gives the additional income needed from products ($4500). Dividing this by the amount per product, gives the number of product sales needed (50).

Chip earns a basic salary of $500 per month. His goal is to earn $5000. The additional income he earns comes from selling products at $90 each. If he wants to reach his goal, we need to first subtract his base salary from his goal income.

$5000 - $500 = $4500

This means that he needs to earn $4500 from selling products. We then divide this by the amount he makes per product to find the number of products he needs to sell.

$4500 / $90 = 50

So, Chip needs to sell 50 products in order to meet his income goal of $5000 per month.

For the interval (-∞, 1), put x = 0.5, then y = - 0.5 + 3 = 2.5.

Therefore, (0.5, 2.5) is a point on y = -x + 3.

Put x = - 1, then y = -(-1) + 3 = 1 + 3 = 4.

Therefore, (-1, 4) is another point on y = -x + 3.

Joining (0.5, 2.5) and (-1, 4), we get the graph of the line y = -x + 3.

For the interval [1, ∞), put x = 1, then y = 2(1) - 4 = -2.

Therefore, (1, -2) is a point on y = 2x - 4.

Put x = 2, then y = 2(2) - 4 = 4 - 4 = 0.

Therefore, (2, 0) is another point on y = 2x - 4.

Joining (1, -2) and (2, 0), we get the graph of the line y = 2x - 4.

The change in height from the starting platform to the stopping point of the roller coaster is 40.75 feet above the ground.

To determine the change in height from where the friends started on the platform to where they stop, we need to calculate the total distance the car traveled vertically. The car first ascends 80 and one half feet and then descends 50 and one fourth feet. The starting platform is 10 and one half feet above the ground.

First, we add the height of the platform to the initial ascent:

Next, we subtract the descent:

The change in height is the final position above the ground minus the starting position, yielding a total change in height of 40.75 feet.

Step-by-step explanation:

It is given that,

Distance covered by Victoria, [tex]d=21\dfrac{1}{2}\ miles=\dfrac{43}{2}\ miles[/tex]

Time taken, [tex]t=\dfrac{2}{3}\ hour[/tex]          

Speed (v) of Victoria is given by total distance divided by total time taken. It is given by :

[tex]v=\dfrac{d}{t}[/tex]

[tex]v=\dfrac{\dfrac{43}{2}\ miles}{\dfrac{2}{3}\ hour}[/tex]

[tex]v=\dfrac{129}{4}\ miles/hour[/tex]

[tex]v=32\dfrac{1}{4}\ miles/hour[/tex]

So, the speed of Victoria is [tex]32\dfrac{1}{4}\ miles/hour[/tex]. Hence, this is the required solution.

As per your defention, horses are the only thing considered "not small".  To find the percentage, you take the number of what you are trying to find the percentage of divided by the total number.

So, 7 dogs + 13 cats + 3 ferrets = 23 Small animals

7 dogs + 13 cats + 3 ferrets + 4 horses = 27 total animals.

So,

[tex]\frac{23}{27}*100[/tex]

The reason we multiply by 100 is because the division gives us a decimal, and a percentage is a part out of 100.

So by doing the calculation we get

85.18%

Mathematics defines a percentage as a number or ratio expressed as fraction of 100.

It is denoted using % sign.

General formula to calculate percentage is:

                                   [tex]\rm Percentage=\dfrac{\rm Value}{\rm Total\: value} \times 100%.[/tex]

For the given question, percentage of small animals is [tex]\rm 85.19\%.[/tex]

[tex]\begin{aligned} \rm Number\:of\:small\:animals &= 7 + 13 + 3\\&= 23\end[/tex]

Small animals includes all animals except horses.

Therefore, percentage of small animals will be:

         [tex]\rm \begin{aligned}\rm Percentage &= \dfrac{\rm Small \:animals}{\rm Total\:animals} \times 100\\\\ &= \dfrac{23}{27} \times 100\\\\ &= 85.19\% \end{aligned}[/tex]
