Answer:
5. f(x) = 10,000 (1.5)^x
Step-by-step explanation:
We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test it.
Initial:
10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
Let's try our equation.
f(x) = 10,000 (1.5)^x
x = 2
10,000(1.5)^2
10,000(2.25) = 22,500
The same!
Answer: 
Step-by-step explanation:
A direct variation equation has the form:
Where <em>k</em> is a constant.
By definition, we know that the perimeter of the square is the sum of the lengths of its sides or, as all the sides are equal, you can multiply the lenght of any side by 4.
Then, knowing that <em>y</em> is the dependent value and <em>x</em> the independent value and the constant <em>k=4, </em> you can write the following direct variation equation that represents the situation.
Answer:
y+2x=8 y=1/2x+2 2y=4-x

2000is ur answer NOT THAT HARD SAIDIFJFJDFJDJSHFHSFHSGJBSGJBsfjbjfbsjfbsbfsj because 5 x 400 is 2000 and the speed is 5
91% = 0.91
<span>25,000 * 0.91 = 22,750 --->cars are passed
</span>
25,000 - 22,750 = 2,250 ---> cars are rejected
answer is B. 2,250 cars
