Linear functions are functions that change at a constant rate

The linear function that models the data is [tex]P(x) = 0.025x -49.695[/tex]

From the question, we have the following ordered pairs

(x,P(x)) = (2005,43%) and (2011,58%)

Start by calculating the slope (m)

[tex]m = \frac{P(x2) - P(x1)}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{58\% - 43\%}{2011 - 2005}[/tex]

Evaluate the differences

[tex]m = \frac{15\%}{6}[/tex]

Evaluate the quotient

[tex]m = 2.5\%[/tex]

The linear function is then calculated as:

[tex]P(x) = m(x - x_1)+ P(x_1)[/tex]

So, we have:

[tex]P(x) = 2.5\%(x - 2005) + 43\%[/tex]

Rewrite as:

[tex]P(x) = 0.025(x - 2005) + 0.43[/tex]

This gives

[tex]P(x) = 0.025x -50.125 + 0.43[/tex]

[tex]P(x) = 0.025x -49.695[/tex]

Hence, the linear function that models the data is [tex]P(x) = 0.025x -49.695[/tex]

Step-by-step explantion

Simplifying

2x + 3 + 25 = 3x + -17

Reorder the terms:

3 + 25 + 2x = 3x + -17

Combine like terms: 3 + 25 = 28

28 + 2x = 3x + -17

Reorder the terms:

28 + 2x = -17 + 3x

Solving

28 + 2x = -17 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

28 + 2x + -3x = -17 + 3x + -3x

Combine like terms: 2x + -3x = -1x

28 + -1x = -17 + 3x + -3x

Combine like terms: 3x + -3x = 0

28 + -1x = -17 + 0

28 + -1x = -17

Add '-28' to each side of the equation.

28 + -28 + -1x = -17 + -28

Combine like terms: 28 + -28 = 0

0 + -1x = -17 + -28

-1x = -17 + -28

Combine like terms: -17 + -28 = -45

-1x = -45

Divide each side by '-1'.

x = 45

Answer: 8 spools

Step-by-step explanation:

There are 12 apartments, and each apartment will need 60 meters of cable, so 12×60= 720 meters of cable needed.

If each spool only has 100 meters and he needs 720 meters, then 720÷100= 7.2. So he would need to purchase at least 8 spools, and will have 80 meters left over.

The solution to the trigonometric equation in the interval is given by:

[tex]x = \frac{\pi}{4}[/tex]

In this problem, the equation is given by:

[tex]\frac{1}{\sin{\theta}} = 2\cos{\theta}[/tex]

Applying cross multiplication, we have that:

[tex]2\sin{\theta}\cos{\theta} = 1[/tex]

Applying a trigonometric identity, we have that:

[tex]\sin{2x} = 1[/tex]

We have that on the interval [0, 2π), [tex]\sin{\left(\frac{\pi}{2}\right)} = 1[/tex]

Hence:

[tex]\sin{2x} = 1[/tex]

[tex]\sin{2x} = \sin{\left(\frac{\pi}{2}\right)}[/tex]

[tex]2x = \frac{\pi}{2}[/tex]

[tex]x = \frac{\pi}{4}[/tex]

For [tex]\frac{3\pi}{4}[/tex], we have that:

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

Hence only the first solution is correct.

Answer:

9, 30, 27

Step-by-step explanation:

To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.

So, we must add the sides to get 66 feet.

n+3n+3+4n-9=66

Combine like terms, and solve:

(n+3n+4n)+(3+-9)=66

8n+-6=66

8n-6=66

n=9

So if n=9, we can easily find the value of the other sides.

3(9)+3=30 feet.

4(9)-9=27 feet

So, the sides are 9, 30, and 27 feet (in order).

Answer:

-10

Step-by-step explanation:

if negative meets a negative its gone come out as a positive

Problem 1

If you need to convert to a mixed number, then follow these steps.

27.2 = 27 + 0.2

27.2 = 27 + 1/5

27.2 = 27 & 1/5

27.2 pizzas is the same as 27 & 1/5 pizzas. In other words, you have 27 whole pizzas plus 1/5 of an extra one.

===========================================

Problem 2

The decimal 1.75 converts to the mixed number 1 & 3/4 because of the steps below.

1.75 = 1 + 0.75

1.75 = 1 + 3/4

1.75 = 1 & 3/4

In my opinion, it is optional to convert to a mixed number for either problem 1 or problem 2. So you can stick with 1.75 as the answer if you want.

===========================================

Problem 3

16 & 3/4 = 16 + 3/4 = 16 + 0.75 = 16.75

To get the unit rate, which is the cost per unit, we divide the total cost over the amount.

cost/amount = (2.89)/(16.75) = 0.1725373

which is approximate.

Round to the nearest penny to get a unit cost of $0.17 per fluid ounce, i.e. a unit cost of 17 cents per fluid ounce.

===========================================

Problem 4

We follow the same idea as problem 3.

4 & 3/5 = 4 + 3/5 = 4 + 0.6 = 4.6

unit cost = (total cost)/(amount)

unit cost = (7.56)/(4.6)

unit cost = 1.643478 dollars approximately

unit cost = 1.64 dollars approximately

===========================================

Problem 5

6 & 1/2 = 6 + 1/2 = 6 + 0.5 = 6.5

Like before, we'll divide the total cost over the total amount.

unit cost = (total cost)/(amount)

unit cost = (8.22)/(6.5)

unit cost = 1.264615 dollars approximately

unit cost = 1.26 dollars approximately

===========================================

Here's another way to look at the unit cost or unit rate.

Notice in problem 5 it says "cost per yard". This is the same as "cost per 1 yard" or "cost for each yard".

We can express the given info as the ratio

6.5 yards:$8.22

Now we want the "6.5 yards" to become "1 yard" to achieve the unit rate.

So we'll divide both parts by 6.5

6.5 yards:$8.22

6.5/6.5 yards:$8.22/6.5

1 yard: $1.26 approximately

For each yard, we'll spend $1.26

Problems 3 and 4 follow similar ideas. So this is why we divided the total cost over the total amount.
