Consider the relation y → 4 x−1 for the domain {3, 5, 7, 9}
(a) Calculate the values for the range.
Answer:
{ 11, 19, 27, 35 }
Step-by-step explanation:
To find the range substitute each value of x from the domain into the relation
x = 3 : y → 4(3) - 1 = 12 - 1 = 11
x = 5 : y → 4(5) - 1 = 20 - 1 = 19
x = 7 : y → 4(7) - 1 = 28 - 1 = 27
x = 9 : y → 4(9) - 1 = 36 - 1 = 35
range is { 11, 19, 27, 35 }

Answer:
[tex]b=\frac{1}{6}[/tex]
Step-by-step explanation:
In [tex]f(x)=a\cos(b(x-c))+d[/tex], [tex]b[/tex] represents a constant related to the period of the function. Here's how it's related:
[tex]b=\frac{2\pi}{T}[/tex], where [tex]T[/tex] is the period of the function.
We're given [tex]T=12\pi[/tex], so solving for [tex]b[/tex]:
[tex]b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}[/tex]

Answer:
1. $40
2. 10 computers
3. 300 miles
Step-by-step explanation:
1. Time between 12:00 and 2:00 is 2 hours, the difference in the money is $10, so the money earned per hour is $5. 5:00 is 3 hours from 2:00, so 25+5*3 is 40, or $40.
2. Time between 1:00 and 3:00 is 2 hours, and the difference in the numbers of computers fixed is 2, so the number of computers fixed per hour is 1. 6:00 is 3 hours from 3:00, so 7+3*1 is 10, or 10 computers.
3. Time between 6:00 and 9:00 is 3 hours and the difference in the distance is 150 miles, so the miles traveled per hour is 50. 12:00 is 3 hours from 9:00, so 150+50*3 is 300, or 300 miles.

Answer:
21√6
Step-by-step explanation:
Here we are to combine 2√54 and 5√24, and want to find any factor that these two quantities may have in common.
2√54 can be factored: 2√54 = 2√9√6, or 2[√6√9], or 6√6
Similarly, 5√24 =5√6√9, or 15[√6]
These two results can and should be added together: 7*3√6 = 21√6
The rectangle below has an area of x2 - 16 square meters and a width of x + 4 meters.
What expression represents the length of the rectangle?
x +4
Length
x2 - 16
Length
meters
Answer:
Length = x - 4 meters
Step-by-step explanation:
Area of a rectangle = length × width
Area of a rectangle = x² - 16
width of the rectangle = x + 4 meters.
Length of the rectangle = ?
Recall:
Difference of two perfect square x² - 16 = (x + 4)(x - 4)
Area of a rectangle = length × width
(x + 4)(x - 4) = length * x + 4
Length = (x + 4)(x - 4) ÷ x + 4
Length = x - 4 meters

If f(x) = 28+x + 7, what is the value of f(-9), to the nearest
hundredth (if necessary)?
Answer:
26
Step-by-step explanation:
Problem: f(x) = 28 + x + 7
Plug in f(-9)
New equation: f(-9) = 28 + (-9) + 7
Simplify: f(-9) = 26
Answer: f(-9) = 26

Seventy weather balloons were sent up. Twenty-eight were found. What percent wer ound? 17
Step-by-step explanation:
let the percent of found balloons be x
given,
total number of balloons= 70

if a dog drinks 8 quart of water a day, how many gallons does the dog drink in 3 days
Answer:
6 gallons
Step-by-step explanation:
There are 4 quarts in gallons, so the dog drinks 2 gallons a day.
When we multiply 2 and 3, we would get 6.
So the dog drinks 6 gallons in 3 days (I don't know about you, but that's a lot of water)
---------------------------------------------------------------------------------------------------------------
Have a great summer :)
Answer:
The dog will drink 6 gallons.
Step-by-step explanation:
