Answer:
n = 70
Step-by-step explanation:
14 * x < 80
x = 6 won't work
14 * 6 = 84 which beyond the boundry.
14 * 5 = 70 which is less than 80 and is divisible by 14
14 * 3 = 42
70 does not have a 3 in it.
So the largest number that has 14 in it and is less than 80 is 70
Answer:
5
Step-by-step explanation:
0.5x=6-3.5
0.5x=2.5
x=2.5÷0.5
x=5
Okay, the exponential function is

The start price of it in t=0 is 3,500, as we can see on the graph. Then, the function becomes

Let's see at t=2, where the price is g=2000:

Take natural logarithm:



So, the difference between t=0 and t=2 is

And then we get the change of x in one year equal to 0.035.
So, the final equation is

You can insert any t and see that it is correct, for example t=7
1.BD=AC
AC^2=(9^2)+(6^2)-2(9)(6)COS115
AC^2=117-108COS115
AC=√71.358
AC=8.447//
