Answer:

Cos theta = sin(90-theta)

so cos 71 = sin(90-71)

cos 71 = sin( 19)

Therefore the answer = sin(19) = 0.14987720966

Hope it helps

Compute i^1+i^2+i^3....i^99+i^100
fgiga [73]

Good morning ☕️

Answer:

<h3>i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰ = 0</h3>

Step-by-step explanation:

Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰

S =  i¹ +  i² +  i³ + . . . + i⁹⁹  +  i¹⁰⁰

S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀

then, S is the sum of 100 consecutive terms of a geometric sequence (an)

where the first term a1 = i¹ = i  and the common ratio = i

FORMULA:______________________

S=(term1)*\frac{1-(common.ratio)^{number.of.terms}}{1-(common.ratio)}

_______________________________

then

S=i*\frac{1-i^{100} }{1-i}

or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1  (we know that i⁴ = 1)

Hence

S = 0

Forty tickets are sold for a raffle with two prizes. You buy two tickets. What is the probability that you will win both prizes
tekilochka [14]
When you first pick a ticket, there are 2 winning tickets and 40 total tickets.  This means that there is a 2/40 chance of your ticket being a winning one.  This fraction can be reduced to 1/20.

After this, there will be 1 winning ticket left and 39 total tickets.  There is a 1/39 chance of the next ticket being a winning one.  We multiply these two fractions together to get our answer.  1/20 * 1/39 = 1/780, so there is a 1/780 chance of having 2 winning tickets.
