Answer:
a68 = -85.2
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 =8.6 (it is the first term)
We can find the common difference by taking the second term and subtracting the first term
7.2-8.6 =-1.4
d=-1.4
n = the term number we are looking for
an = 8.6 -1.4(n-1)
We are looking for the 68th term so n=68
a68 = 8.6 -1.4(68-1)
= 8.6 -.1.4(67)
= 8.6-93.8
=-85.2
Answer:
44/80
Step-by-step explanation:
draw a line from 13cm upwards to the graph line and then draw a horizontal line from that point to the y axis to find that you get 18 bananas
then draw a line from 20cm upwardsto the graph line and then draw a horizontal line from that point to the y axis to find that you get 62 bananas
62-18=44 you do this because the shop buys banana lengths between 13 and 20
only from 13 to 20 = 44
so out of 80 (the total) it should be 44/80
Answer:
It is transversal because it can separate two lines and become n perpendicular

Answer:
B
Step-by-step explanation:
42 = 2*x + 2*6
2x=42-12=30
x=15
Answer:
See below.
Step-by-step explanation:
You don't show what the function is, but I'll explain how to do it.
The average rate of change of function f(x), from x = a to x = b, is given by the fraction:
Since I don't know what the function is, I cannot evaluate the function at x = a and at x = b, which in your case are x = 2 and x = 3, but you can do it.
Here are the steps you need to do:
1) Evaluate the function at x = 3. Get a value for f(3).
2) Evaluate the function at x = 2. Get a value for f(2).
3) Evaluate the following fraction, after writing the values for f(3) and f(2) that you found in steps 1) and 2) above.
The denominator above is easy. It's just 1.
Try it and see what you get. You can write the function and your answer in the comments if you need more help.
