Answer:
Step-by-step explanation:
Use the coordinates of the given points to find the slope.
difference in y-coordinates = -3 - 6 = -9
difference in x-coordinates = 2 - (-1) = 3
slope = -9/3 = -3
Answer: Choice A
S9 = (9/2)*(2+26)
===============================================
The formula is
Sn = (n/2)*(a1+an)
where
Sn = sum of the first n terms (nth partial sum)
n = number of terms
a1 = first term
an = nth term
In this case,
n = 9
a1 = 2 (plug in n = 1 into the formula an = 3n-1 and simplify)
an = a9 = 26 (plug n = 9 into the formula an = 3n-1 and simplify)
So,
Sn = (n/2)*(a1+an)
S9 = (9/2)*(2+26)
will help us find the sum of the first 9 terms of this arithmetic sequence
Answer:
When you have to get these measurements completely then you apply some multiplication as follows: Calculate cubic feet for different units (formula) From feet: length (ft) × width (ft) × height (ft) = cubic feet From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet

I don't know, sorry
Answer: $1.50
Step-by-step explanation:
The item's normal price is $15.
Han uses a 10% off coupon so he saves 10% which is:
= 15 * 10%
= $1.50
He therefore bought the item for $8.50.
