The function f (x) = 57.8 (1.02) x gives the approximate number of passenger cars, in millions, in the United States x years aft
Leviafan [203]
Assume this is f(x)=57.8(1.02)ˣ. This is a 2% increase each year.

When f(x)=200, 57.8(1.02)ˣ=200, (1.02)ˣ=200/57.8
Taking logs, xlog(1.02)=log(200/57.8), x= log(200/57.8)/log(1.02)=62.685.
Add 1960 to 62.685=2023 approx.

I can't find x y or z​
Sholpan [36]

Answer:

x = 4\sqrt{3}

y = 6

z = 8

Step-by-step explanation:

keep in mind I'm not doing that well with geometry so this might all be wrong lol

x is part of a 30 60 90 triangle.

so x is 4\sqrt{3}

next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.

4 + 6 = 10

10^2 = 100

100 = a^2 + b^2

y = 6 and z = 8 bc 36 + 64 = 100
