Answer:
-i
Step-by-step explanation:
i^0=1
i^1=i
i^2=-1
i^3=-i
i^4=1
This repeats so we want to see how many 4 factors of i there is in i^(23) which is 5 with a remainder of 3.
So i^(23)=i^3=-i.
i^(23)=i^(5*4+3)=(i^4)^5 * (i^3)=(1)^5 * (-i)=1(-i)=-i.
Answer:
The variation equation is
step-by-step explanation:
From the question, the two masses are
This implies that the product of the two masses
Moreover, the force,f varies directly with the products of the two masses
Also, the force varies inversely with the square of the distance,r
Joining equation 1 and 2, we got
But the constant of variation is k
Multiplying the right hand side of the equation by k, we got
Answer:
<h2>220</h2>
Step-by-step explanation:
bowling balls without holes = 77 and 35%
find: how many bowling balls in the store?
let x be the total
its a ratio and proportion:
<u> 77 </u> = <u> x </u>
35 100
cross multiply:
35 (x) = 77 (100)
x = 7700 / 35
x = 220 ------>> total number of balls in the store
Answer:
x = 0
Step-by-step explanation:
<u>Step 1: Find the equation</u>
<em>Since all of the x values of the ordered pairs are at 0, then this means x=0.</em>
Answer: x = 0
