Jane spends $15 each time she travels the toll roads. She started the month with $240 in her toll road account. The amount, A (in dollars), that she has left in the account after r trips on the toll roads is given by the following function.

How much money does Jane have left in the account after 8 trips on the toll roads?

(b) How many trips on the toll roads can she take until her account is empty?

Answers

Answer 1

$120 money does Jane have left in the account after 8 trips on the toll roads and She has to make 16 trips to make her account empty.

What is Equation?

Two or more expressions with an equal sign is called equation.

Given that Jane spends $15 each time she travels the toll roads..

Jane started the month with $240 in her toll road account.

The amount, A (in dollars), that she has left in the account after r trips on the toll roads is given by the following function

A(r)=240-15r.

Now for 8 trips the amount she left is

A(8)=240-15(8)

=240-120

=120

So $120 money does Jane have left in the account after 8 trips on the toll roads.

$240/15

=16.

She has to make 16 trips to make her account empty.

Hence $120 money does Jane have left in the account after 8 trips on the toll roads and She has to make 16 trips to make her account empty.

A toy rocket is shot vertically into the air from a launching pad 5 feet above the ground with an initial velocity of 32 feet per second. The height h, in feet, of the rocket above the ground at t seconds after launch is given by the function

h(t)=-16t²2 +32t+5.

How long will it take the rocket to reach its maximum height? What is the maximum height?

Answers

It takes the rocket to reach its maximum height h max = 17(ft).

The object's maximum height is the highest vertical position along its trajectory.

How to find a maximum height?The object's maximum height is the highest vertical position along its trajectory. Before reaching the highest point, the object is flying upwards and then falls. It means that the vertical velocity is equal to 0 at the highest point of projectile motion (v y = 0 v y = 0 v_y=0).

So, h(t) = -16+ 32t+5:

t max = time for maximum heightt max = 32 / 2*(-16)= 32 / 32 = 1h max = the maximum height above the groundh  max = h(1) = -16() + 32*1 +5-16+32+5 =  -16+ 37 = 21

Then, h max rocket = the maximum height of the toy rocket

h max rocket  = 21 -5 = 17(ft)t max = 1 secondh max = 17(ft)

Therefore, it takes the rocket to reach its maximum height h max = 17(ft)

The object's maximum height is the highest vertical position along its trajectory.

If f(x) = x² + 5 and g(x) = 3x, find (f o g)(x) and (g o f)(x) .

Answers

Answer:

[tex](f \circ g)(x) = 9x^2 + 5\\\\\\(g \circ f)(x) = 3x^2 + 15[/tex]

Step-by-step explanation:

We are given
[tex]f(x) = x^2+5\\\\g(x) = 3x\\\\(f\circ g)(x) = f(g(x))\\\\[/tex]

To find this, wherever you see an x in f(x) substitute the expression in g(x)

[tex](f\circ g)(x) = f(g(x))\\\\= f(3x)\\\\= (3x)^2 + 5\\\\=9x^2 + 5\\\\\\[/tex]

Wherever there is an x in the expression for g(x) substitute that x with the expression in f(x)

During a sale, Neil found digital cameras on sale for $204 that had previously cost $600. What percentage is the discount? Write your answer using a percent sign (%).

Answers

We need to find the percentage of the discount over a camera that had previously cost $600 and now is on sale for $204.

In order to find that percentage, we need to find the total discount (previous cost minus cost on sale) and then divide the result y the previous cost.

The total discount is:

[tex]\$600-\$204=\$396[/tex]

Then, dividing this result by the previous cost, we obtain:

[tex]\frac{\$396}{\$600}=0.66[/tex]

Now, we can write it as a percentage:

y = [∛(x-6)] - 2

Step-by-step explanation:

To find the inverse :

Solve for xSwap x and y

Solve for x using balancing method or solve and ping method:

y= (x-2)³+6

y - 6 = (x+2)³

∛(y-6) = x+2

Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots e.t.c

Given the radical

[tex]\sqrt[]{12}[/tex]

The slope of both inequalities is 3/2. If the slopes of two lines are the same, the lines are said to be parallel. This means both inequalities are parallel lines

For parallel lines, there is no solution because the lines do not intersect (meet).

Since both inequalities give parallel lines, there will be no solution (option C)

Now

In the middle of the graph, we have the mean, then every section is added/subtracts an std to the mean. In our case with one std we get the values that we are looking.

Answer: The percentage of students scored between 170 and 246 on the exam is 68%.

which expression is equivalent to [tex] \sqrt{15} \times \sqrt{12} [/tex]

Answers

Consider that √15 and √12 can be written as follow:

√15 = √(3*5)

√12 = √(3*4)

Moreover, √15*√12 = √(15*12). Then, you can write:

√(15*12) = √(3*5*3*4) = √(3^2*2^2*5) = 3*2√5 = 6√5

Hence, the equivalent expression is 6√5

Solve 1/3x + 4/9 = 7/9

Answers

We want to solve

[tex]\frac{1}{3}x+\frac{4}{9}=\frac{7}{9}[/tex]

We can subtract 4/9 on both sides.

[tex]\begin{gathered} \frac{1}{3}x+\frac{4}{9}-\frac{4}{9}=\frac{7}{9}-\frac{4}{9} \\ \\ \frac{1}{3}x=\frac{7}{9}-\frac{4}{9} \\ \\ \frac{1}{3}x=\frac{7-4}{9} \\ \\ \frac{1}{3}x=\frac{3}{9} \end{gathered}[/tex]

Now we have 3/9 on the right side, but we can simplify that fraction to 1/3

[tex]\begin{gathered} \frac{1}{3}x=\frac{3}{9} \\ \\ \frac{1}{3}x=\frac{1}{3} \end{gathered}[/tex]

And now we have the result!

[tex]x=1[/tex]

Therefore the final result is x = 1

find the percent of change. Round to the nearest whole percent original:26 new:30

Answers

We want to find the percentage change;

We can do that using the formula;

[tex]\text{ \%P}=\frac{New-Original}{\text{Original}}\times100\text{\%}[/tex]

Given:

[tex]\begin{gathered} \text{Original = 26} \\ \text{New = 30} \end{gathered}[/tex]

Substituting the given values;

[tex]undefined[/tex]
