Answer:
perpendicular
Step-by-step explanation:
We have that
the expressions is <span>∑ i=1 to 5 (4i)
for i=1-----------> (4*1)=4
</span>for i=2-----------> (4*2)=8
for i=3-----------> (4*3)=12
for i=4-----------> (4*4)=16
for i=5-----------> (4*5)=20
∑ i=1 to 5 (4i)=[4+8+12+16+20]=60
the answer is 60
Answer:
1.107 = r
Step-by-step explanation:
To solve this for r, do the following:
Add 10 to both sides, to isolate the r term on the left: 18r^(-8) = 8
Divide both sides by 18, to isolate r^(-8): r^(-8) = 8/18
Invert both sides: r^8 = 9/4
Take the natural log or both sides:
8 ln r = ln 9 - ln 4, or
8 ln r = 0.8109, so that ln r = 0.1014
to find r, raise e to the power ln r on the left and e to the power 0.1014 on the right:
ln r 0.1014
e = e = 1.107 = r
