The Initial count of a certain type of bacteria in a culture is 350. If the bacteria grows at the rate of 20% per hour, which
function models the number of bacteria after thours?
Answers
Answer:
I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).

A model rocket is launched upward at a speed of 96 feet per second from a platform 7 feet above the ground. The path of the rocket can be modeled by the projectile equation, h(t)=-16t^2+v₀t+h₀
1. What is the maximum height the rocket will reach?
2. What is the average rate of change from the initial height to the maximum height?
Answers
Answer:
151 ft
48 ft/s
Step-by-step explanation:
h(t)=-16t^2+v₀t+h₀
v₀ = 96 and
h₀ = 7
h(t)=-16t^2+96t+7
The maximum height is at the vertex
The x values of the vertex is at
x = -b/2a = -96/ (2*-16) = -96/-32 =3
Substitute this into the function to find the maximum height
h(3) = -16 ( 3)^2 +96*3+7
-16*9 +288+7
151
The maximum height is 151 ft
Average rate of change from 0 to 3

You have decided to cash in all of the coins you have been saving for the summer. In total you have $7.20. You only have dimes and quarters, and you know that you have twice as many dimes as you do quarters. How many quarters do you have in total? How many dimes? (HINT: think about what you know of dimes and quarters!)
Answers
Answer:
The number of quarters in total = 16 quarters
The number dimes = 32 dimes
Step-by-step explanation:
The given information are;
The total amount of money in held = $7.20
The denomination of the money held = Dimes and quarters
The number dimes = 2 × The number of quarters
Given that a dime = 10 cents = $0.1
A dollar = 25 cents = $0.25
Let the number of quarters in the sum of money = X
Therefore, we have;
X × $0.25 + 2 × X × $0.1 = $7.20
X × $0.25 + X × $0.2 = $7.20
X × $0.45 = $7.20
X = $7.20/$0.45 = 16
Therefore, the number of quarters = 16
The number of quarters in total = 16 quarters
The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes
The number dimes = 32 dimes.

if f(x) = 3x2 + 10, what is f( - 7)?
Answers
The value of function f(-7) is 157.
What is a function?Functions have the property that each input is related to exactly one output. The function defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
For the given situation,
The function is f(x) = 3 x^2 + 10
Then f( - 7) becomes,
⇒ [tex]f(-7)=3(-7 )^{2} +10[/tex]
⇒ [tex]f(-7)=147+10[/tex]
⇒ [tex]f(-7)=157[/tex]
Hence we can conclude that the value of function f(-7) is 157.

A bakery sold 168 mocha cupcakes in a day, which was 84% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
Answers
Answer:
200 cupcakes
Step-by-step explanation:
We have, 84% × x = 168
or,
84/100 × x = 168
Multiplying both sides by 100 and dividing both sides by 84,
we have x = 168 × 100/84
x = 200
If you are using a calculator, simply enter 168×100÷84, which will give you the answer.
Answer:
200
Step-by-step explanation:
168 is 84/100 of the total cupcakes. You just need to divide by 84 and the multiply by 100. So:
168÷84=2
2×100=200
