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).

Answers
Answer:
z*(z - 3) = 520
Step-by-step explanation:
Use the following representations:
Width: W
Length: L = W + 3, or W = L - 3
Area = L*W = L*(L - 3) = 520
Equation b) is the correct one: z*(z - 3) = 520
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 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

The maximum height is 151 ft
Average rate of change from 0 to 3

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
16X = 22 + 5x
what is x
Answers
Answer:
x=2
Step-by-step explanation:
16x = 22+5x
1) 16x-5x = 22 + 5x - 5x =
11x = 22
x=2
Answer:
x=2
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
16*x-(22+5*x)=0
Pull out like factors :
11x - 22 = 11 • (x - 2)
Solve : 11 = 0
This equation has no solution.
A non-zero constant never equals zero.
Solve : x-2 = 0
Add 2 to both sides of the equation :
x = 2

The number of words he can type is proportional to the number of minutes. If the test is 18 minutes long, how many words will Kenny be able to type?
Answers
Answer:
720
Step-by-step explanation:
Given the data:
Minutes ___0___3 ____6____a____12
W/typed__ 0___120 __ ____360 __480
If number of words typed is proportional to number of minutes
Word typed α number of minutes
Word typed = k * number of minutes
k = constant of proportionality
Take
120 = k * 3
k = 120/3 ; k = 40
If test is 18 minutes long ;
Word typed = k * 18
Word typed = 40 * 18
Word typed = 720
