t The function f(t) = 390(1.0085) 365 represents the change in a quantity over t days. What does the constant 1.0085 reveal about the rate of change of the quantity?
The function is (growing/decaying) exponentially at a rate of _% evey ___.
Answers
Answer: The function is *growing* exponentially at a rate of *0.85%* every *year*
Step-by-step explanation:
The function is growing exponentially at a rate of 0.85% every year.
What is the exponential decay equation?The exponential decay equation is given by:-
y = (1 ± r)ⁿ
Where r is the rate of decay and A is the initial amount and n is the time period.
The function is given in the question below as:
The function f(t) = 390(1.0085)³⁶⁵ ....(i)
This represents the change in quantity over t days.
As per the given exponential decay equation,
⇒ f(t) = 390(1.0085)³⁶⁵
We can above function rewrite as:
⇒ f(t) = 390(1 + 0.0085)³⁶⁵
⇒ f(t) = 390(1 + 0.85/100)³⁶⁵
⇒ f(t) = 390(1 + 0.85%)³⁶⁵
Compare to the standard exponential decay equation, and we get
⇒ r = 0.85%
Therefore, the function is growing exponentially at a rate of 0.85% every year.

Write the rule for f(h(x))
Answers
Answer:
f(h(x)) = 2x - 4
Step-by-step explanation:
To find the rule for f(h(x)), substitute h(x) = 2x + 3 into f(x) = x - 7:
f( ) = ( ) - 7 becomes
f(h(x)) = (2x + 3) - 7, or 2x + 3 - 7, or f(h(x)) = 2x - 4

Isabel’s class has collected 90 cans in a food drive. They plan to sort the cans into n bags, with an equal number of cans in each bag. Write an expression to show how many cans there will be in each bag.
Answers
Answer:

Step-by-step explanation:
There are 90 cans, and each bag MUST have an equal amount of cans, so if we had, let's say 2 bags, then there would be 45 bags. We got this by doing 90/2. 2 being n, the expression would be 90/n.

We first have to find 2 pairs of sides that proportional.
35/20=42/24=7/4
and 21/b should be 7/4 as well because if we want the triangles to be similar the sides should be in proportion.
