Answer:
Step-by-step explanation:
Additional fee per person = $3
Additional fee for 's' person = 3*s = 3s
C = 60 + 3s
The maximum value can be determined by taking the derivative of the function.
(dh/dt) [h(t)] = h'(x) = -9.8t + 6
Set h'(x) = 0 to find the critical point
-9.8t + 6 = 0
-9.8t = -6
t = 6/9.8
Plug the time back into the function to find the height.
h(6/9.8) = -4.9(6/9.8)^2 + 6(6/9.8) + .6
= 2.4
And I don't understand your second question.
Answer:
2/5 of the cake
Step-by-step explanation:
First, find how much she gave away:
2/5 + 1/5
= 3/5
Then, to find how much she has left, subtract 3/5 from 1
1 - 3/5
= 2/5
So, she has 2/5 of the cake left for herself
The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
<h3>What are exponential functions?</h3>
When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.
here usual form is specified below. They are written in several such equivalent forms.
The equation of the function is given as:

Set x = 0, 1, 2 and 3

This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).

Natural numbers: 2
Whole numbers: 0
Integers: -34
Rational Numbers: 3/5
Irrational numbers: pi
Natural numbers are 1, 2, 3, 4, 5..
Whole numbers are all natural numbers and zero.
Integers are all whole numbers plus negative numbers.
Rational numbers are all numbers that can be represented by a fraction. This includes integers because they can be fractions over 1.
Irrational numbers include decimals that are nonterminating and that do not repeat.
