Describe how the graphs of functions f and g are related: f (x) = 2cos(pi x) g(x) = 2cos(2pi x)

Same amplitude: 2,

but the period is half in the second case. Period of the first one is 2, in the second one is 1, so it will oscillate twice as many times than the first one, but it will go from -2 to 2, both of them

Hope it helps

F and g have the same amplitude: 2

f and g have the same trajectory: cosine function

But, g has half of the frequency of f

Answer:

A. 30800

B.39600

C. 17600

Step-by-step explanation: 0.12*$35000= 4200 35000-4200 = $30800

$45000*0.12=$5400 $45000-$5400= $39600

$20000*0.12=$2400 $20000-$2400= $17600

The cost of a car rental is $25 per day plus 22 per mile. You are on a daily budget of $90. Write and solve an inequality to f

lara31 [8.8K]

Answer: You can drive, at most, 2.95 miles per day.

x ≤ 2.95

Step-by-step explanation:

In a single day, you can spend at most $90

Then if C represents the cost of renting the car, then we will have the inequality:

C ≤ $90

Now let's find the equation for C.

We know that we have a fixed cost of $25 plus $22 per mile, then if you drive x miles, the total cost will be $25 plus x times $22, or:

C = $25 + x*$22.

We can now replace that in the inequality:

$25 + x*$22 ≤ $90

Now let's isolate the variable x

x*$22 ≤ $90 - $25

x*$22 ≤ $65

x ≤ $65/$22 = 2.95

x ≤ 2.95

You can drive at most, 2.95 miles per day.

To find other inequalities with the same solution we can start with the solution:

x ≤ 2.95

Now let's multiply both sides by a number (the units of the number can be dollars, in that way we can make a similar problem)

Let's multiply both sides by $10:

x*$10 ≤ 2.95*$10 = $29.5

x*$10 ≤ $29.5

Now let's add the same number in both sides, for example, $5.

x*$10 + $5 ≤ $29.5 + $5 = $34.5

x*$10 + $5 ≤ $34.5

We could write this problem as:

"To rent a cab in your city, you have an initial cost of $5, plus $10 for each mile driven. How many miles could you drive if at most you can spend $34.50?"

You could be more creative with the problem, but this is the way in which you can craft problems of this type when you already know the solution.

Every day The burger buns restaurant serves 1/5 of a bottle of cherry soda to the customers for how many days will 1 4/5 bottles

kogti [31]

9 because if you change 1 and 4/5 to an improper fraction and you’ll get 9/5. If you multiply 1/5 by 9 you’ll get 9/5.

B+11/3=-2 what number does b represent

gtnhenbr [62]

B+ 11/3= -2
⇒ b= -2 -11/3
⇒ b= -6/3 -11/3
⇒ b= -17/3
⇒ b= -5 2/3

Final answer: b= -5 2/3~
