These lines are considered vertical angles, meaning that the amounts on both sides have to be equal. The answer is C because 15 x 1 = 15 and 3 x 1 = 3. 20 + 3 = 23 and 15 + 8 = 23.

The number of camera phones shipped globally can be modeled by the function y = 1.28e 1.31x where x is the number of years since
OlgaM077 [116]

Answer: 895 phones

Step-by-step explanation:

Given that :

The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997

y = number of camera phones ; x = number of years since 1997

The number of camera phones shipped in the year 2002 can be obtained thus ;

x = 2002 - 1997 = 5 years

y = 1.28e^(1.31 * 5)

y = 1.28e^6.55

y = 1.28(699.24417)

y = 895.03254

y = 895 phones

(15-4i)(6-3i) = a +bi
kati45 [8]

The real part of the result is the product of the real parts of the factors and the product of the imaginary parts:

a = 15*6 - (-4)(-3) = 90 -12 = 78

_____

You can treat this the same as any other product of binomials except that i² = -1.

... (15 -4i)(6 -3i) = 15(6 -3i) -4i(6 -3i) = 15·6 -15·3i -4·6i +4·3i²

... = 90 -45i -24i +12i² = (90 -12) -69i = 78 -69i
