Yeah you did well on the table
Answer:
2
Step-by-step explanation:
Since the equation is in y=mx+b form, the y-intercept can easily be identified by just looking at it.
Knowing that b is the y-intercept and m is the slope. Any number in place of these variables are y-intercept and slope respectively.
That being said, the y-intercept is 2.
Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304
Have you learnt about prime numbers yet? 5 is a prime number so you can't break it up into smaller numbers other than obviously 5*1. 39 is not a prime number. At first glance you should be able to tell that its a multiple of 3 right?
39=3*13
Now you have smaller numbers.
3*13*5=13*15.
I guess that's what the answer is.
