Answer:
First term: -10
Fourth term: -55
Eighth term: -115
Step-by-step explanation:
I am assuming the means -5(3n-1). To find the first term, plug in 1. You will get -5(3*1-1) or -5*2 or -10.
To find the fourth term, plug in 4. You will get -5(3*4-1) or -5*11 or -55.
To find the eighth term, plug in 8. You will get -5(3*8-1) or -5*23 or -115.
So the answers are -10, -55, and -115.
3. 49
4. 26
u just add up all the sides then subtract it from 180
Answer:
Step-by-step explanation:
Let's solve for f.
y=3x−2x2findf(3)
Step 1: Flip the equation.
−6df2inx2+3x=y
Step 2: Add -3x to both sides.
−6df2inx2+3x+−3x=y+−3x
−6df2inx2=−3x+y
Step 3: Divide both sides by -6dinx^2.
−6df2inx2
−6dinx2
=
−3x+y
−6dinx2
f2=
3x−y
6dinx2
Step 4: Take square root.
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2
Answer:
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2
Answer:
The answer is 40
Step-by-step explanation:
because half of 80 miles is 40
You're right - it's D. Both ratios are equal to 1/2.
