2. what is the range?
Answer:
domain is x = 3
Thus domain means that for every fruit cup costs $3
Range is f(20) = 60
Step-by-step explanation:
We are given;
Total students for the fruit cup party = 18
Total teachers for the fruit cup party = 2
Cost of each fruit cup =$ 3
Delivery charge = $ 10
Now, the total number of people attending the party = Total number of students + Total number of teachers
Thus;
Total number of people attending party = 18 + 2 = 20
Since cost of each fruit cup is $3.
Thus, for 20 fruit cups, the function is;
f(x) = 20x where x is cost of each fruit cup.
It means the cost of 20 fruit cups = $3 × 20 = $60
Thus, domain is x = 3
Thus domain means that for every fruit cup costs $3
Range is f(20) = 60
A.
y = −15x + 900
B.
y = −15x − 900
C.
y = 15x − 900
D.
y = 15x + 900
Answer: The correct answer is 3.
Step-by-step explanation:
Let the number of ninths needed be taken as 'x'
We need to find the number of ninths needed to make;
,
The equation for this becomes:
Hence, we need 3 times ninths to get us the fraction of .
Answer:
If a square has an area of 144 square inches and is reduced by a factor of 1/6, it means that both the length and width of the square are multiplied by the square root of 1/6.
To find the new side length, we can take the square root of 1/6 and multiply it by the original side length.
Original side length = sqrt(144) = 12 inches
New side length = (1/6)^(1/2) * 12 inches
Simplifying the calculation:
New side length = (1/√6) * 12 inches
Now we can calculate the new side length:
New side length ≈ 3.27 inches (rounded to two decimal places)
To find the new area, we square the new side length:
New area = (3.27 inches)^2 ≈ 10.68 square inches (rounded to two decimal places)
Therefore, after reducing the square by a factor of 1/6, the new side length is approximately 3.27 inches, and the new area is approximately 10.68 square inches.
B) period 3, amplitude 3
C) period 4, amplitude 1.5
D) period 4, amplitude 3
Answer:
Option: A is the correct answer.
A) Period: 3 , amplitude : 1.5
Step-by-step explanation:
We know that Period of a function is the smallest value such that the function repeats after a fixed time.
and also the amplitude of the function is the height above or below the mid-line.
After looking at the graph we see that the period of the function is: 3
Since the function is repeating itself after every x=3.
Also, the mid-line of the function is: y= -0.5.
Hence, the height above the mid-line is: 1+0.5 = 1.5
Hence, amplitude= 1.5
