I would make a table and plug values(or just plug in x values) in to figure out the equation's graph:  (plug in values that will make it easy for you since you have a √)

f(x) = 3(√x)

x = 0

f(0) = 3(0) = 0       ------> (0 , 0)

x = 1

f(1) = 3(√1) = 3(1) = 3  ------> (1 , 3)

x = 4

f(4) = 3(√4) = 3(2) = 6   ------>    (4 , 6)

The sum of the integers -9, 4, 10, -4, 8, -4 is calculated by adding the numbers together, which totals 5.

To find the sum of the integers -9, 4, 10, -4, 8, -4, we add them together:

-9 + 4 + 10 + (-4) + 8 + (-4) = 5.

We can group the positive and negative numbers to make this simpler:

(4 + 10 + 8) = 22

(-9 - 4 - 4) = -17

Adding the results of the positive and negative groups gives us:

22 + (-17) = 5.

Therefore, the sum of the given integers is 5.

How many classes could Anna take so that the total cost for the month would be the same?

5 classes

What is the total monthly cost when it is the same for both gyms?

$37.50

Step-by-step explanation:

The number of classes Anna could take so the total cost for the month would be the same is 5.

The total monthly cost when it is the same for both gyms would be $37.50.

When the total cost is the same, both equations for the gym would be equal to each other.

7.5x = 5.5x + 10

In order to determine the value of x, take the following steps:

Combine similar terms

7.5x - 5.5x = 10

Add similar terms together

2x = 10

Divide both sides by 2

x = 5

Total cost = 7.5 x 5 = $37.50

Answer:

[tex]f * g = 21x ^ 2 + 32x +12[/tex]

Domain: all real numbers [tex](-\infty, \infty)[/tex]

Step-by-step explanation:

We have the functions [tex]f (x) = 3x + 2[/tex] and [tex]g (x) = 7x + 6[/tex]

We want to find f*g. Then we must multiply the function f by the function g.

Note that the function [tex]f (x) = 3x +2[/tex] is a linear function, therefore its domain is all real numbers. In the same way the function [tex]g (x) = 7x + 6[/tex] is also a linear function and its domain is all real numbers.

The multiplication of f * g will be

[tex]f * g = (3x + 2) (7x + 6)\\\\f * g = 21x ^ 2 + 18x + 14x +12\\\\f * g = 21x ^ 2 + 32x +12[/tex]

The function g(x) is a quadratic function and its domain is the intercept of the domain of f(x) with the domain of g(x), that is, all real numbers.

The relationship between Roberts age and Julia’s age is given by:

r = j+3            ....[1]

where,

r is the Robert's age and j represents the Julia's age in years

We have to find the table of values represents the relationship between Roberts age and Julia’s age

if r = 9 years

then;

[tex]9 = j+3[/tex]

Subtract 3 from both sides we have;

6 = j

or

j = 3 years

Similarly:

if r = 15 years

then;

[tex]15= j+3[/tex]

Subtract 3 from both sides we have;

12 = j

or

j = 12 years

If r = 21 years

then;

[tex]21= j+3[/tex]

Subtract 3 from both sides we have;

18 = j

or

j = 18 years

Therefore, the table of values represents the relationship between Roberts age and Julia’s age is, Table C

Step-by-step explanation:

How many selfies did Tania take? (my first answer would be too many, but that's probably not the answer you're looking for :-) )

We know that each cousin appear 2 or 3 times overall.

If she would have taken each cousin exactly 2 times, that would be 16 cousins/photos

If she would have taken each cousin exactly 3 times, that would be 24 cousins/photos

We know there's exactly 5 cousins per photo...

so we have to find a multiple of 5 cousins/photos that is between 16 and 24.

The only possibility is 20 cousins/photos.  20 / 5 = 4 photos.

Final answer:

Tania took 4 selfies with her cousins. Each cousin appeared in exactly 2 selfies, with some appearing a third time to account for 16 total cousin appearances divided by 5 cousins per selfie.

Explanation:

The problem presented is a combinatorial puzzle involving selfies and cousins. Since each cousin is in either 2 or 3 pictures, we can try to minimize the number of pictures by assuming each cousin is in exactly 2 pictures first. If there are 8 cousins and 5 cousins per picture, then by multiplying 8 by 2 (every cousin appears exactly 2 times), we get 16 cousin appearances in total.

Since each selfie has 5 cousins, we divide the total cousin appearances by the number of cousins per picture: 16 / 5, which results in 3.2. However, since it's not possible to have a fraction of a picture, we need at least 4 selfies to cover all appearances. Yet, this leaves us 4 extra appearances (because 4 pictures would mean 20 cousin appearances in total).

These 4 extra appearances account for the fact that some cousins appear 3 times instead of just 2. Therefore, Tania must have taken 4 selfies with her cousins to cover the 16 cousin appearances with some cousins appearing an additional third time.

These are the factors of 36:

1, 2, 3, 4, 6, 9, 12, 18, 36

1, 2, 3, 4, 6, 9, 12, 18, 36

1 x 36 = 36

1, 2, 3, 4, 6, 9, 12, 18, 36

2 x 18 = 36

1, 2, 3, 4, 6, 9, 12, 18, 36

3 x 12 = 36

1, 2, 3, 4, 6, 9, 12, 18, 36

4 x 9 = 36

Answer:

Function for given situation is : [tex]V(t)=3000(0.70)^t[/tex]

Value of computer after 4 years = $720.3.

Step-by-step explanation:

Given that the value of a $3000 computer decreases about 30% each year. Now we need to write a function for the computers value V(t). then we need to find about how much will the computer be worth in 4 years.

It clearly says that value decreases so that means function represents decay.

For decay we use formula:

[tex]A=P(1-r)^t[/tex]

where P=initial value = $3000,

r= rate of decrease =30% = 0.30

t= number of years

A=V(t) = future value

so the required function is [tex]V(t)=3000(1-0.30)^t[/tex]

or [tex]V(t)=3000(0.70)^t[/tex]

Now plug t=4 years to get the value of computer after 4 years.

[tex]V(4)=3000(0.70)^4[/tex]

[tex]V(4)=720.3[/tex]

Hence final answer is $720.3.

Answer:

A = $3000(0.70)^t

Step-by-step explanation:

100% - 30% = 70%.  Thus, the common ratio in this exponential function is 0.70.

Use a formula with the form of the compound amount formula:

A = P(1 + r)^t, where r is the common ratio as a decimal fraction and t is the number of years.

Here, A = $3000(1 - 0.30)^t, or    A = $3000(0.70)^t

If a local city collects 8% sales tax if the total purchase was $216 then $17.28 is collected for sales tax.

A relative value indicating hundredth parts of any quantity is known as Percentage.

Given that a  local city collects 8% sales tax

The total purchase was $216.

We need to find the amount collected for sales tax.

To find this we have to find 8% of 216.

Convert 8% to the decimal value.

8/100=0.08

Now multiply 0.08 with 216

0.08×216

$17.28

Hence, if a local city collects 8% sales tax if the total purchase was $216 then $17.28 is collected for sales tax.

#SPJ3

The amount collected for sales tax is $16.

Step 1: Understand the Problem

The total purchase amount ($216) includes the sales tax. We need to find how much of this amount is the sales tax itself.

Step 2: Convert the Percentage to a Decimal

Convert the sales tax rate from a percentage to a decimal.

[tex]\[ \text{Sales Tax Rate} = \frac{8}{100} = 0.08 \][/tex]

Step 3: Set Up the Equation

Let ( P ) be the pre-tax purchase amount and ( T ) be the total amount including tax. The relationship can be written as:

[tex]\[ T = P + \text{Sales Tax} \][/tex]

Since the sales tax is 8% of the pre-tax amount,

[tex]\[ \text{Sales Tax} = 0.08 \times P \][/tex]

Thus, the total amount is:

[tex]\[ T = P + 0.08P = 1.08P \][/tex]

Step 4: Solve for the Pre-Tax Amount

We know the total amount ( T ) is $216.

[tex]\[ 216 = 1.08P \][/tex]

To find ( P ):

[tex]\[ P = \frac{216}{1.08} \][/tex]

[tex]\[ P \approx 200 \][/tex]

Step 5: Calculate the Sales Tax

Now, find the sales tax:

[tex]\[ \text{Sales Tax} = 0.08 \times P \][/tex]

[tex]\[ \text{Sales Tax} = 0.08 \times 200 \][/tex]

[tex]\[ \text{Sales Tax} = 16 \][/tex]

Therefore the amount collected for sales tax is $16.

Answer:

Yeah it's Impossible

Step-by-step explanation:

Each pencil box usually contains same amount of pencils. In given context  the number of pencils in five boxes is 10 pencils.

Suppose that its given that 'a' boxes contains 'b' items, then, assuming that each box contains 'x' items, then

[tex]x + x + ... + x \text{ (a times)} = b\\\\x \times a = b\\\\x = \dfrac{b}{a}[/tex]

Thus, there are 'b/a' items contained in each box.

Since there are six pencils in three boxes, let there are 'x' pencils in one box, then we have:

[tex]x + x + x = 6\\3 \times x = 6\\\\\text{Dividing both sides by 3}\\\\x = \dfrac{6}{3} = 2[/tex]

Thus, there are 2 pencils in each pencil box.

Thus, for 5 boxes, we get [tex]2 \times 5 = 10[/tex] pencils.

Thus,

In given context  the number of pencils in five boxes is 10 pencils.

https://brainly.com/question/2689177

Final answer:

By using proportional reasoning, if three boxes contain 36 pencils, then five boxes would contain 60 pencils.

Explanation:

If thirty-six pencils are packed in three boxes, then there are twelve pencils per box because 36 divided by 3 equals 12.

To find out how many pencils are packed in five boxes, we multiply twelve pencils (the number of pencils per box) by five boxes.

Therefore, 12 pencils/box × 5 boxes = 60 pencils in five boxes.

This is a simple proportional reasoning problem, often encountered in mathematical exercises in school.

Halving the height halves the volume, but halving the radius quarters it; their effects on volume differ.

It seems there might be a typo or a mistake in your reasoning. Let's reassess the situation:

Original cone:

- Radius, [tex]\( r = 2 \)[/tex]

- Height, [tex]\( h = 6 \)[/tex]

- Volume, [tex]\( V_1 = \frac{1}{3} \pi r^2 h = \frac{1}{3} \pi (2)^2 (6) = 8\pi \)[/tex] cubic units

Now, you're considering two scenarios:

1. If the height is changed to [tex]\( h = 3 \)[/tex]:

  - New volume, [tex]\( V_2 = \frac{1}{3} \pi (2)^2 (3) = 4\pi \)[/tex] cubic units

2. If the radius is changed to \( r = 1 \):

  - New volume, [tex]\( V_3 = \frac{1}{3} \pi (1)^2 (6) = 2\pi \)[/tex] cubic units

Now, let's analyze the effects:

- Changing the height from 6 to 3 reduces the volume by half (from [tex]\( 8\pi \)[/tex] to [tex]\( 4\pi \)[/tex]).

- Changing the radius from 2 to 1 reduces the volume by a factor of [tex]\( \frac{1}{4} \)[/tex] (from [tex]\( 8\pi \)[/tex] to [tex]\( 2\pi \))[/tex].

So, changing the height to half of its original value reduces the volume by half, while changing the radius to half of its original value does not reduce the volume by half but rather by a quarter. Therefore, the effects are not the same.

Step-by-step explanation:

[tex]100xh=1,150\qquad\text{divide both sides by}\ 100x\neq0\\\\\dfrac{100xh}{100x}=\dfrac{1,150}{100x}\\\\\boxed{h=\dfrac{115}{x}}[/tex]

To solve the equation \( 1,150 = 100 \times x \times h \) for \( h \), you want to isolate \( h \) on one side of the equation. Follow these steps:
**Step 1: Understand the equation**
The equation is saying that 100 times the product of \( x \) and \( h \) is equal to 1,150.
**Step 2: Isolate \( h \)**
To solve for \( h \), you need to get \( h \) by itself on one side of the equation. Right now \( h \) is being multiplied by \( 100 \times x \). To undo this, you'll divide both sides of the equation by \( 100 \times x \).
**Step 3: Perform the division**
Divide both sides of the equation by \( 100 \times x \):
\[
\frac{1,150}{100 \times x} = \frac{100 \times x \times h}{100 \times x}
\]
**Step 4: Simplify both sides**
On the right-hand side, \( 100 \times x \) in the numerator and \( 100 \times x \) in the denominator cancel each other out:
\[
\frac{1,150}{100 \times x} = h
\]
**Step 5: Result**
You are left with \( h \) by itself on one side of the equation and \( \frac{1,150}{100 \times x} \) on the other:
\[
h = \frac{1,150}{100 \times x}
\]
Now \( h \) has been solved in terms of \( x \), and you can find the value of \( h \) if you know the value of \( x \) by simply substituting that value into this equation and performing the calculation.
