Answer:

$\Huge\boxed{D.14.6}$

Step-by-step explanation:

Hello There!

We can solve for x using trigonometry

More specifically the law of sines

In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)

so to find x we use this equation

$\frac{x}{sin59} =\frac{17}{sin90}$

step 1 multiply each side by sin 59

now we have

$x=\frac{17sin59}{sin90}\\x = 14.6$

so we can conclude that x = 14.6

3x + 5y = 7 How to solve it

Lubov Fominskaja [6]

Answer:

x=1 and y=4/5

Step-by-step explanation:

Given system of equations

3x+5y=7

5x+10y=13

Multiply first equation by 2

2(3x+5y)=2(7)

6x+10y=14

Eliminate y-variable to get "x"

6x+10y=14

- 5x+10y=13

x = 1

Substitute x=1 into either equation and find "y"

3x+5y=7

3(1)+5y=7

3+5y=7

5y=4

y=4/5

Therefore, x=1 and y=4/5

A new car sells for $27,500. The value of the car decreases by 14% annually. You want to sell the car when it's worth about $400

NemiM [27]

Answer: 13 years.

Step-by-step explanation:

The price decreases by 14% anually

To find the decimal form, you have 14%/100% = 0.14

So, the year zero, the price is $27,500

After one year, the price is:

P = $27,500 - 0.14*$27500 = $27,500*(0.86)

After the second year, the price is:

P = $27,500*(0.86)^2

and so on, so we want to find x such that:

P = $27,500*(0.86)^x = $4000

0.86^x = $4000/$27,500

Now, using the natural logaritm rule:

a^x = b

x = ln(a)/ln(b)

x = ln($4000/$27,500)/ln(0.86) = 12.8

We can round it up to 13, so after 13 years the price of the car is about $4000
