Answer:

$t = \cfrac{1}{2}$

Step-by-step explanation:

Given equation:

$4(t+\cfrac{1}{4})=3$

Divide both sides by 4:

$t+\cfrac{1}{4}=\cfrac{3}{4}$

Subtract 1/4 from both sides:

$t = \cfrac{3}{4}- \cfrac{1}{4}$

$t = \cfrac{2}{4}$

Simplify:

$t = \cfrac{1}{2}$

Which two points are on the graph of y = -x + 3?

ch4aika [34]

The points (0, 3) and (4, -1) are on the graph of y = -x + 3.

I have a site that I use a lot that is perfect for problems like these. It's called Desmos.com. It's basically a free online graphing calculator that is super helpful for most problems relating to graphs.

Every year, a car loses 15% of the value it had the year before. If the car's initial value is $ 24,000, then how long will it t

ella [17]

Answer:

4.62 years

Step-by-step explanation:

Half the car's value =>$24,000/2 = $12,000

The formula for exponential decrease =

y = a(1 - r)^t

y = Initial value = $24,000

a = Value after time t = $12,000

r = Decrease rate = 15% = 0.15

t = time in years =??

Hence,

24,000 = 12000 ( 1 - 0.15)^t

Divide both sides by 12000

24000/12000 = 12000 ( 0.85)^t/ 12000

2 = 0.85^t

We take the logarithm of both sides

log 2 = log (0.85)^t

log 2 = t log 0.85

Divide both sides by log 0.85

t = log 2/log 0.85

t = 4.62098120373 years

Approximately = 4.62 years

It would take 4.62 years to be worth half the initial price
