Answer: a) b) c) d)
Step-by-step explanation:
Since f is an exponential function.
So, it is expressed as
Here f is the present value
p is the initial value
r is the rate of growth per time period
t is the time period.
(a) b represents the 1-unit growth factor for f.
(b) c represents the n n-unit growth factor for f.
(c) d represents the m m-unit growth factor for f.
Write a formula that expresses c in terms of b.
Since
Hence, a) b) c) d)
Find the assessed amount:
12000 x 0.80 = 9600
Multiply the assessed amount by tax rate:
9600 x 0.015 = 144
He pay $144
Assuming you have to solve it for f, you have to rewrite the equation in a form like f = ...
So in the form it is now, you're solving for C. You're not actually going to get values for f or C, for that you'd need more information.
So how do we convert the C = ... form into an f = ... form? Step by step you want to isolate f using simple rules:
step 1) I want to get rid of the 5 so we're dividing left and right by 5:
C/5 = 5(f-32)/(9*5) this simplifies to C/5 = (f-32)/9
step 2) Get rid of the 9 by multiplying by 9 left and right:
9*C/5 = 9*(f-32)/9 simplifies to f-32
step 3) I want to get rid of the -32 so I'm adding 32 left and right:
9*C/5 + 32 = f-32 + 32 simplifies to 9*C/5 + 32 = f
Now just swap left and right, and we get:
f = 9C/5 + 32
All you have to learn is the basic tricks like adding left and right, multiplying left and right. Hope this helps.
Answer:
This parabola has a maximum of 10
Step-by-step explanation:
Since the y-value cannot increase past 10, the maximum value of this function would be 10.
Answer:
b
Step-by-step explanation:
(2a + ★)(2a - ★) =4a²-b²
If you substitute b for ★ in the equation. We have;
(2a + b)(2a - b) = 4a² - b²
4a² - 2ab + 2ab -b² = 4a²-b²
4a²-b²= 4a² - b².
So 'b' is correct
