f(x) = -4x2 + 4x - 4
Find f(3)
Answer:
-28
Step-by-step explanation:
The solution is the value of f(3) = -28.
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
given expression is,
f(x) = -4x^2 + 4x - 4
now, we have to find the value of f(3).
so, we have to put x = 3, in the expression.
we get,
f(x) = -4x^2 + 4x - 4
f(3) = -4* 9 + 4*3 -4
or, f(3) = -36 + 12 -4
or, f(3) = -28
Hence, The solution is the value of f(3) = -28.

The population in Smalltown in 2010 was 45,230 people and is growing exponentially at a
rate of 2%. What will the population be in 2030?
O 67,475
O 81.928
O 67.209
O 82.414
Answer:
The first option
67475
Step-by-step explanation:
Step one:
Given data
The population in Smalltown in 2010 was 45,230
rate= 2%= 0.02
time t= 20 years
Step two:
Let P(t) = population t years after 2010
= 45230e^0.02t
Population in 2030 = P(20)
= 45230e^0.02t(20)
= 45230e^0.4

The graph shows the proportional relationship between rainfall during the growing season and seasonal growth of a type of plant. What does the point (8,6) represent? If the plants grew 12 mm one season, how much rain fell?
Answer/Step-by-step explanation:
✔️The point (8, 6) represents seasonal plant growth of 6 mm with 8 cm of rainfall during the growing season.
✔️To determine how much rain fell if the plants grew 12 mm one season, find the value of x (rainfall) when y (plant growth) = 12.
From the graph, when y = 12, x = 16.
This means that when the plant grew 12 mm, 16 cm of rainfall was recorded.
Therefore:
If the plants grew 12 mm one season, 16 cm rainfall fell.
find the surface area of the cylinder using pie.

For a charity event, raffle tickets are printed such that they have a vowel (excluding y) as the first character and a prime number less than 10 as the second digit. (Note that 1 is not a prime number.) The probability that the winning ticket has the vowel contained in the word event and the digit is the number of letters in the word event is
Answer:
P=5%
Step-by-step explanation:
In order to solve this problem, we can use the following formula for the probability of two independent events:
P(A and B)=P(A)*P(B)
so we need to find the probability for each event to happen.
They are asking for the probability that the winning ticket will have the letter e on it. There are 5 vowels in the alphabet (a, e, i, o and u). Therefore the probability for the first letter to be e is:
[tex]P(A)=\frac{desired}{total}[/tex]
[tex]P(A)=\rac{1}{5}[/tex]
We also know there are 4 prime numbers between 0 and 10 (2, 3, 5, 7) so the probability for the number to be a 5 is:
[tex]P(B)=\frac{1}{4}[/tex]
so the probability of getting a ticket that starts with an e and ends with a 5 is:
P(A and B)=P(A)*P(B)
[tex]P(A and B)=(\frac{1}{5})(\frac{1}{4})[/tex]
[tex]P(A and B)=\frac{1}{20}[/tex]
so the probability is 5%
The probability that the winning ticket has the vowel contained in the word event and the digit is the number of letters in the word event is P=5%.
What is probability?The chance of happening an event out of all the possible outcomes is called the probability of an event.
The probability of two independent events
P(A and B)=P(A)*P(B)
The probability that the winning ticket will have the letter e on it. There are 5 vowels in the alphabet (a, e, i, o and u). So, the probability for the first letter to be e is:
P(e) =1/5
There are 4 prime numbers between 0 and 10 (2, 3, 5, 7) so the probability for the number to be a 5 is:
P(B) =1/4
So, the probability of getting a ticket that starts with an e and ending with a 5 is:
P(A and B)=P(A)*P(B)
= 1/5 x 1/4 =1/20
In percentage , probability is 1/20 x 100 % =5%
Hence, the probability is 5%

The height of a pebble dropped from a cliff 20,00 feet heigh is described by formula h(t)=20,000 + 5t^2. How long will the pebble take to reach a height of 32,500 feet?
Answer:
It will take 50 seconds for the pebble to reach the height
Step-by-step explanation:
To calculate the time, simple substitute h(t) for 32,500
So we have
32,500 = 20,000 + 5t^2
5t^2 = 32,500-20,000
5t^2 = 12500
t^2 = 12500/5
t^2 = 2500
t = square root of 2500
t = 50 seconds

Total cost = 40 + 0.2t
Step-by-step explanation:
Given:
Fixed cost for call = $40
Each message cost = $0.20
Number of message = t
Find:
Equation of total cost
Computation:
Equation of total cost
Total cost = Fixed cost for call + (Each message cost)(Number of message)
Total cost = 40 + 0.2t
