The house was bought for $125,000 in 1990, the overage rate is 7.85%, what year will the purchase of the house be worth 3 times

olga55 [171]

Answer: 2005

Step-by-step explanation:

Exponential function to determine the value of item after t years,

$f(x)=A(1+r)^t$ , where r= rate of growth, A=Initial value.

As per given , A = 7.85% = 0.0785

A = $125,000

Substitute all values in function, we get

$f(x)=125000(1+0.785)^t$

When f(x)= 3A , then

$3A=A(1.0785)^t\\\\\Rightarrow\ 3=(1.0785)^t$

Taking tog on both sides , we get

$\ln 3=t\ln 1.0785\\\\\Rightarrow\ t=\dfrac{\ln 3}{\ln 1.0785}\\\\\Rightarrow t=\dfrac{1.09861228867}{0.0755711868471}\approx15$

The year will be 1990+15= 2005

Hence, the required year = 2005

First you plug in the known variables. So 192 for x and 3 for t. Lastly you get y = 192(3)

The measure of angle C is 60 degrees. All the angles have to equal 180 degrees when added together. Since there is one right angle, 90 degrees, and one 30 degree angle, the last angle can only equal 60 degrees.
