  • Supplementary Angles: Angles that add up to 180°

Step-by-step explanation:

<u>Step 1: Define</u>

We can see from the diagram that the 2 angles are supplementary

(6x - 10)° + (7x + 8)° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                                                                                         13x - 2 = 180
  2. [Addition Property of Equality] Add 2 on both sides:                                    13x = 182
  3. [Division Property of Equality] Divide 13 on both sides:                                x = 14

For every 12 students that wore sneakers, there were 9 students that wore boots. How many students wore sneakers if 24 students
Olenka [21]

Answer:

C (32)

Step-by-step explanation:

12 sneakers / 9 boots = x sneakers / 24 boots

the ratio is 4:3 so divide 24 by 3 and multiply by 4

12 / 9 = (24 / 3 x 4) / 24

12 / 9 = 32 / 24

32 students wore sneakers

The current population of a town is 10,000 and its growth in years can be represented by P(t) = 10,000(0.2)^t, where t is the ti
DiKsa [7]

Answer:

1) 20%

2) Choice a.

Step-by-step explanation:

P(t)=10000(0.2)^t

1) P(0) is the population initially.

P(1) is the population after a year.

\frac{P(1)}{P(0)} represents the population increase factor.

So let's evaluate that fraction:

\frac{P(1)}{P(0)}

\frac{10000(0.2)^1}{10000(0.2)^0}

\frac{0.2^1}{0.2^0}=\frac{0.2}{1}=0.2

0.2=20%

2) Let's figure out the population growth in terms of months instead of years.

P(t)=10000(0.2)^{t}

We want t to represent months.

A full year is 12 months, in a full year we have that P(1)=10000(0.2)^1=10000(0.2)=2000

So we want a new P such that P(12)=2000 since 12 months equals a year.

Let's look at the functions given to see which gives us this:

a) P(12)=10000(0.87449)^{12}=2000 \text{approximately}

b) P(12)=10000(0.87449)^{12(12)}=0 \text{ approximately}

c) P(12)=10000(0.87449)^{\frac{1}{12}}=9889 \text{approximately}

d) P(12)=10000(0.87449)^{12+12}=400 \text{approximately}

So a is the function we want.

Also another way to look at this:

P(t)=10000(.2)^t where t is in years.

P(t)=10000(.2^\frac{1}{12})^t where t is in months.

And .2^\frac{1}{12}=0.874485 \text{approximately}

ale4655 [162]

Answer:

2

Step-by-step explanation:

You are right as rain. You go to the x axis.

Find x = 3.5

f(3.5) is the y value of x = 3.5

f(3.5) = 2

It might help you a bit if you wrote it as a point (3.5,2)
