Answer:
3/5
Step-by-step explanation:
We can find ∅ by using the tangent function since we have the opposite and adjacent sides of ∅.
tan(∅)=1/2
tan^-1(tan(∅))=tan^-1(1/2)
∅=26.57
Since we are looking for cos(2∅), then we have cos(2(26.57))=cos(53.14)≈0.6
So the exact value is 3/5

Find the solution of the system of equations.
−x−3y= −3
x−6y= −24
Answers
Answer:
(-6 , 3)
Step-by-step explanation:
-x-3y= -3
x-6y= -24
1. solve each eq so they make x=___
-x = -3 + 3y
x= 3 - 3y
and
x = -24 + 6y
2. set = to each other and solve for y
3 - 3y = -24 + 6y
27 = 9y
y = 3
3. plug the y value into one of the x=__ eq's and solve for x
x = 3 - 3y
x = 3 - 3(3)
x = 3 - 9
x = - 6
your solution is ( -6 , 3 )

Last January, the average cost of a one-night stay at a hotel was $132.52. Since then, the hotel has changed ownership, and
several changes have been made to the cost of staying at the hotel.
• Last summer, the new owners adjusted room prices so that the average cost of a one-night stay increased by $34.65.
Last December, the new owners offered a $57.80 per night discount to guests who belong to their loyalty club.
. Last week, the new owners introduced a service fee of $4.95 for any reservation made over the phone.
How much should a customer expect to pay for a one-night stay if they are a member of the hotel's loyalty club and make
their reservation over the phone?
Answers
Answer:
$114.32
Step-by-step explanation:
Original Price: $132.52
increased: $34.65
Loyalty Club: -$57.80
Phone Fee: $4.95
You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.
The amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77
What will be the amount?The average cost of a one-night stay at a hotel was $132.52. Since then, the hotel has changed ownership, and several changes have been made to the cost of staying at the hotel. Last summer, the new owners adjusted room prices so that the average cost of a one-night stay increased by $34.65.
Last December, the new owners offered a $57.80 per night discount to guests who belong to their loyalty club. Last week, the new owners introduced a service fee of $4.95 for any reservation made over the phone.
The price will be calculated as:-
Original Price: $132.52
increased: $34.65
Loyalty Club : - $57.80
Phone Fee: $4.95
You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.
= 132.52 + 34.65 + 4.95 - 57.80 = $113.77
Therefore the amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77.

Answers
Answer:
Tallest = Morgan
Shortest = Suzanna
Step-by-step explanation:
Assuming Latisha = 1
0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.
1.09 is more than 1, Morgan is taller than Latisha.
Morgan is tallest and Suzanna is shortest, Latisha in the middle.

The sum of five consecutive multiples of 4 is 20.Find the smallest integer.
Answers
Answer:
The smallest integer is -4.
Step-by-step explanation:
Let the smallest integer be x.
Since the integers are all multiples of 4, they are
=> x, x+4, x+8, x+12 and x+16
=> x + x+4 + x+8 + x+12 + x+16 = 20
=> 5x + 40 = 20
Subtract 40 from both sides of the equation
5x +40 - 40 = 20 - 40
5x = -20
Divide both sides by the coefficient of x(which is 5)
[tex]\frac{5x}{5} = \frac{-20}{5}[/tex]
x = -4
∴ the smallest integer is -4.
