Answer:
224,688
Step-by-step explanation:
The number of members is modeled by ...
m(t) = 45000·1.04^(t-1975) . . . . where t is the year number
Then for t=2016, the membership is expected to be ...
m(2016) ≈ 45000·1.04^41 ≈ 224,688
Membership in 2016 could be estimated to be about 225,000.
___
The multiplier per year is 1+4% = 1.04. The exponent tells how many times that multiplier is repeated.
Answer:
Step-by-step explanation:
A complex number is defined as z = a + bi. Since the complex number also represents right triangle whenever forms a vector at (a,b). Hence, a = rcosθ and b = rsinθ where r is radius (sometimes is written as <em>|z|).</em>
Substitute a = rcosθ and b = rsinθ in which the equation be z = rcosθ + irsinθ.
Factor r-term and we finally have z = r(cosθ + isinθ). How fortunately, the polar coordinate is defined as (r, θ) coordinate and therefore we can say that r = 4 and θ = -π/4. Substitute the values in the equation.
Evaluate the values. Keep in mind that both cos(-π/4) is cos(-45°) which is √2/2 and sin(-π/4) is sin(-45°) which is -√2/2 as accorded to unit circle.
Hence, the complex number that has polar coordinate of (4,-45°) is
