PLEASE HELP.

1 answer:

5 0

Answer: f(x)= 500x + 12000
If the base population is 12000, which I’m sure it is then 500 would be added annually to that population per year which is why it says 500x. Therefore it would be the first one because it’s linear and it’s adding 500 per year.

Use law of sines or law of cosines to find the length of side AB Please show work !!

scoray [572]

Answer:

$AB = 11.3$

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

$\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}$

So, we have:

$\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}$

Make AB the subject

$AB = \frac{15}{\sin(70)} * \sin(45)$

$AB = \frac{15}{0.9397} *0.7071$

$AB = 11.3$

What is 40% of 65 (please have a step by step explanation)

NNADVOKAT [17]

Answer:

25.6

Step-by-step explanation:

To work this out you would first divide 65 by 10, which gives you 6.5. This is because by dividing it by 10 you are working out 10%. Then to work out 40% you would multiply 10% which is 6.5 by 4, which gives you 25.6.

1) Divide 65 by 10.

$65/10=6.5$
