Answer:
B) A herd of lions whose numbers triple every decade.
Step-by-step explanation:
Situations that can be modeled by exponential functions:
A situation can be modeled by exponential functions when the change is a multiplication or a division, not a sum or subtractions.
In this question:
In option A, C and D the measures are a sum or subtractions, as the rate of change is always the same. So it rests option B as the answer, as tripling is multiplying by 3.
This is relatively easy because that 25 is a perfect square, whose (square) roots are 5 and -5. x^2-10x+25 = (x - 5)(x - 5). Note how (-5)(-5) = +25, and how -5x - 5x = -10x.
The roots are { (x-5), (x-5) }.
Answer:
The correct solution is "$1618.79".
Step-by-step explanation:
The given values are:
Home price,
= $300,000
Down payment,
= 10%
Mortgage,
= $270,000
Rate,
r = 6%
Time,
t = 30 years
As we know,
⇒ ![PV=P[\frac{1-(1+r)^{-n}}{r} ]](https://tex.z-dn.net/?f=PV%3DP%5B%5Cfrac%7B1-%281%2Br%29%5E%7B-n%7D%7D%7Br%7D%20%5D)
On substituting the values, we get
⇒ ![270 000= P[\frac{1-(1+\frac{6}{1200} )^{-12\times 30}}{\frac{6}{1200} } ]](https://tex.z-dn.net/?f=270%20000%3D%20P%5B%5Cfrac%7B1-%281%2B%5Cfrac%7B6%7D%7B1200%7D%20%29%5E%7B-12%5Ctimes%2030%7D%7D%7B%5Cfrac%7B6%7D%7B1200%7D%20%7D%20%5D)
⇒

Answer:
Each quart is 1.31 to the customer.
Step-by-step explanation:
Cost of 1 quart to Wong = 0.75
Cost to you or I = 0.75 * 175/100 = 1.31
He sells each quart for 1.31 dollars.
