Answer:
[tex]f(0) = 0[/tex]
[tex]f(70) = 16.74[/tex]
[tex]f(58.5) = 15.30[/tex]
[tex]x \geq 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2\sqrt x[/tex]
Solving (a): f(0)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(0) = 2 * \sqrt 0[/tex]
[tex]f(0) = 2 * 0[/tex]
[tex]f(0) = 0[/tex]
Interpretation:
This implies that, the cost of 0 paints is $0
Solving (b): f(70)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(70) = 2 * \sqrt{70[/tex]
[tex]f(70) = 2 * 8.37[/tex]
[tex]f(70) = 16.74[/tex]
Interpretation:
This implies that, the cost of 70 paints is $16.74
Solving (c): f(58.5)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(58.5) = 2 * \sqrt{58.5[/tex]
[tex]f(58.5) = 2 * 7.65[/tex]
[tex]f(58.5) = 15.30[/tex]
Interpretation:
This implies that, the cost of 58.5 paints is $15.30
Solving (d): The domain
[tex]f(x) = 2\sqrt x[/tex]
Set the radicand x to [tex]\geq 0[/tex]
i.e.
[tex]x \geq 0[/tex]
Hence:
The domain is [tex]x \geq 0[/tex]

You make an initial deposit of $2,500 in an account that offers 6% simple interest per year. How much will be in the account after 4 years?
Enter the correct answer in the box.
Answer:
3100
Step-by-step explanation:
3100
The amount of money in the account that he has after 4 years will be $3100.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A = P + (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
You make a $2,500 initial deposit into an account that pays 6% simple interest per year.
Then the amount of money in the account that he has after 4 years will be given as,
A = 2500 + (2500 x 6 x 4)/100
A = 2500 + 600
A = $3100
The amount of money in the account that he has after 4 years will be $3100.

What is the value of x, rounded to one decimal place?
Answer:
x ≈ 5.9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 2.7² = 6.5²
x² + 7.29 = 42.25 ( subtract 7.29 from both sides )
x² = 34.96 ( take the square root of both sides )
x = [tex]\sqrt{34.96}[/tex] ≈ 5.9 ( to 1 dec. place )

Step-by-step explanation:
[tex]7y = 8x - 14[/tex]
get rid of the Y and put in a 6
[tex]7(6) = 8x - 14[/tex]
[tex]7 \times 6 = 42[/tex]
[tex]42 = 8x - 14[/tex]
we need to get rid of the negative 14 so its only 8x.
to get rid of 14 on one side you add it to the other
[tex]42 + 14 = 56[/tex]
[tex]56 = 8x[/tex]
to get X by itself have to divide 8 by both sides
[tex]56 + \div 8 = 7[/tex]
[tex]8x \div 8 = x[/tex]
[tex]x = 7[/tex]

Answer:
The tanks by volume per fish from least to greatest:
Tank C, Tank A, Tank B
Step-by-step explanation:
A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
Order the tanks by volume per fish from least to greatest.
Tank A holds 40 L and 5 fish.
= 40L/5 fishes
= 8 volume per fish
Tank B holds 100 L and 12 fish
= 100L/12 fishes
= 8.3333333333 volume per fish
Tank C holds 180 L and 23 fish.
= 180L /23 fish
= 7.8260869565 volume per fish
The tanks by volume per fish from least to greatest
Tank C, Tank A, Tank B

50°
25°
12x-3
Find the x
Answer:
X=9
Step-by-step explanation:
We want to first understand that a triangle will always be 180°. Next, we want to look at both where 25° and 12x-3 are. If we look closely we can see that they are the vertical angles of the interior angles of the triangle. To solve this algebraically we have to basically add all the angles (including 12x-3) to solve for x.
Adding all the angles together would look like this: 25+50+12x-3. Next, add up all like terms to get 12x+72=180. You want to get x by itself by subtracting by 72 on both sides to get 12x=108. Isolate x by dividing by 12 on each side which results in x=9

The high school decided to buy new uniforms for the girls' and boys' basketball teams. They plan to buy 35 uniforms with a total cost of $1,235. The store offers discounts based on the number of items the school buys, as shown. What will the discounted price be for the high school?
Answer:
1049.75
Step-by-step explanation:
take 15% off of 1235 or 1235 divided by 15%
The discount will be 15% and the discounted price is $1049. 75
What is discount?A discount is a price reduction you offer a customer. There are also other methods that you can use to attract customers.
Given:
price for 35 uniforms = 1235
as, there is 15% discount for the items 25- 49 items.
So, there is 15% discount for 35 uniforms
Thus, the discounted price is
=1235 (1- 15%)
=1235 (1- 0.15)
=1235 x 0.85
= $1049. 75
Hence, the discounted price is $1049. 75.
