Answer:

<em>1500(1.02)^x  +   600x</em> is how much he has in savings at the end of x years where it be in the bank or elsewhere

Step-by-step explanation:

x is in years

Let's just think about the investment of 1500 in an account earning 2% per year.

Before the years even start, you are at 1500 ( present value).

The next year (year 1), it would be 1500*.02+1500=(1500)(1.02).

The next year (year 2), it would be 1500(1.02)(.02)+1500(1.02)=1500(1.02)(1.02).

We keep multiplying factors of (1.02) each time.

So for year x, you would have saved 1500(1.02)^x.

Now we are saving 50 cash per month. Per year this would be 12(50) since there are 12 months in a year.  12(50)=600.  

So the first year you would have 600.

The second year you would have 600(2) or 1200.

The third year you would have 600(3) or 1800.

Let's put this together:

1500(1.02)^x  +   600x

Convert the angle measure 40° to a radian measure?
Sophie [7]

Answer:

The answer is

<h2>\frac{2\pi}{9}  \\</h2>

Step-by-step explanation:

To convert an angle from degrees to radians multiply the value by \frac{\pi}{180} .

From the question the value is 40°

It's equivalent in radians is

40 \times  \frac{\pi}{180}   =  \frac{40\pi}{18 0}  =  \frac{2\pi}{9}  \\

We have the final answer as

\frac{2\pi}{9}  \\

Hope this helps you

A boutique prices merchandise by adding 80%. It later decreases by 25% the price of items that do not sell quickly. Does the ord
k0ka [10]
The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.  

For example, 80% of 100 = $80.  The price would be $180.

Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.  

25% of 100 is not the same as 25% of 180.

Which equation represents the line that passes through points (1, –5) and (3, –17)? y = negative 6 x + 1 y = 6 x + 1 y = negativ
Paraphin [41]

Answer:

Using y = mx + c

slope = -17+5/3-1 = -12/2 = -6

Using point (1 , - 5)

y + 5 = -6(x - 1)

y + 5 = - 6x + 6

y = - 6x + 6 - 5

y = - 6x + 1

Hope this helps.
