Answer:

as written there, they are not inverses

proof by counter example:  since g(1) = 3  , but g^-1(3) = -5/3 != 1

Step-by-step explanation:

g(g^-1(x))  == x    if they are indeed inverses

1/(1/x -2)  + 2  =   x/(1-2x) + 2  != x    so, they are not inverses

Step-by-step explanation:

The number of months that having average high temperature above freezing (32 F) is approximately for 3 months.

A function is defined as a relation between a set of inputs having one output each. It is a set of permissible outputs with the property that each input is related to exactly one output.

For the given situation,

The function is [tex]t=21.55 cos(\frac{\pi }{6}(m-7) )+43.75[/tex]

The temperature for months are calculated using the function t.

Here m = 1 refers January,

m = 2 refers February and so on.

Now substitute m = 1 for January,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(1-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(-6) )+43.75[/tex]

⇒ [tex]t=22.2[/tex]

For February m = 2,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(2-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(-5) )+43.75[/tex]

⇒ [tex]t=25.08[/tex]

For march m = 3,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(3-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(-4) )+43.75[/tex]

⇒ [tex]t=32.9[/tex]

For April m = 4,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(4-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(-3) )+43.75[/tex]

⇒ [tex]t=43.75[/tex]

For May m = 5,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(5-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(-2) )+43.75[/tex]

⇒ [tex]t=54.525[/tex]

For June m = 6,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(6-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(-1) )+43.75[/tex]

⇒ [tex]t=62.41[/tex]

For July m = 7,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(7-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(0) )+43.75[/tex]

⇒ [tex]t=65.3[/tex]

For August m = 8,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(8-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(1) )+43.75[/tex]

⇒ [tex]t=62.41[/tex]

For September m = 9,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(9-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(2) )+43.75[/tex]

⇒ [tex]t=54.525[/tex]

For October m = 10,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(10-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(3) )+43.75[/tex]

⇒ [tex]t=43.75[/tex]

For November m = 11,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(11-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(4) )+43.75[/tex]

⇒ [tex]t=32.975[/tex]

For December m = 12,

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(12-7) )+43.75[/tex]

⇒ [tex]t=21.55 cos(\frac{\pi }{6}(5) )+43.75[/tex]

⇒ [tex]t=25.087[/tex]

Thus from the above temperatures of each month, the temperature for three months are less than 32°F.

Hence we can conclude that the number of months that having average high temperature above freezing (32 F) is approximately for 3 months.

Answer:

Zero Solutions

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+13=3(x+6)+1

3x+13=(3)(x)+(3)(6)+1(Distribute)

3x+13=3x+18+1

3x+13=(3x)+(18+1)(Combine Like Terms)

3x+13=3x+19

3x+13=3x+19

Step 2: Subtract 3x from both sides.

3x+13−3x=3x+19−3x

13=19

Step 3: Subtract 13 from both sides.

13−13=19−13

Answer:

6,400

Step-by-step explanation:

The calculation is shown below:-

But before that find the total number of pound in five local bonds

= 400 × 5

= 2,000

Now the amount at six week later is

= Food pounds + 3 × number of pounds + 3 × suplus shipment

= 10,000 + 3 × 2,000 - 3 × 3,200

= 10,000 + 6,000 - 9,600

= 6,400

Therefore according to the given situation the correct answer is 6,400

Answer:

both will give you the same amount of money, $100,000, so I would consider the fact that I'd rather only have 200 people give me money then 500. So I would say 200 people giving me $500 would be the best option

Answer:

Answer One: 3 miles. Answer Two:  105.

Step-by-step explanation:

Answer One: Due to it being 7/10s we have to get 2/5 to a tenth. We multiply 2 and 5 by 2 to get 4/10s subtract 7/10s to 4/10s getting 3/10s which is equal to 45 minutes. So that means 4/10s is equal to an hour. The change in height is 3/10s. Answer Two: It begins it's flight at 7/10s above ground so after 45 minutes it's now at 4/10s due to 45 minutes equaling 3/10s, you need another hour to reach the ground so add 45 minutes to 60 minutes to get 105.

Answer:

5 adults went on the trip.

Step-by-step explanation:

There are 14 children ($75 each) and the total was $1475. We need to find out how many adults were there ($85 each)

c is for children and a is for adults

equation:  $75c+ $85a = $1475

$75(14)+ $85a= $1475

$1050 + $85a = $1475

-1050                   -1050

$85a = $425

85a/85 = 425/85

a = 5

5 adults went on the trip. Hope this helps! :)

There were 5 adults that went on the trip.

Unitary method is finding the value for a single unit.

According to the given question During spring break, a class of 14 children went to Walt Disney World in Florida the price for each child’s ticket was 75 dollars.

So, Cost of tickets of 14 children is

= (14 × 75) dollars.

= 1050 dollars.

Total amount spent on tickets for children and adults is 1475 dollars.

∴ Total amount spent for tickets for the adults is

= ( 1475 - 1050 ) dollars.

= 425 dollars.

Given price of one ticket for adult is 85 dollars, So for 425 dollars the no. of tickets will be

= 425/85 dollars.

= 5 tickets which states there were 5 adults.

Answer:

8/6 or 1 1/3

Step-by-step explanation:

Step 1:

4 ( 3q - 2 ) = 4q + 2q      Equation

Step 2:

12q - 8 = 4q + 2q      Multiply

Step 3:

12q - 8 = 6q      Combine Like Terms

Step 4:

12q = 6q + 8       Add 8 on both sides

Step 5:

6q = 8      Subtract 6q on both sides

Step 6:

q = 8 ÷ 6     Divide

Answer:

q = 8/6 or 1 1/3

Hope This Helps :)

Answer:

Hi there! The answer is q=4/3.

Step-by-step explanation:

First—Distrubute the 4 on each side of 3q-2. You should get 12q-8 on the left side of the equation.

Second— Combine like terms. You should see the 4q+2q obviously. Since they have the same letters, they should be combined Into 6q.

as a result you should have 12q-8 on the left side and 6q on the right side.

Switch 6q’s place with -8. But make sure you change the signs of negative and positives as you switch.

Now you should have 12q-6q=8.

Combine like terms again which will be 12q-6q Which will become 6q.

Now you should have 6q=8. divide 6 to both sides of the equation.

Since 6/6 = 1, there should be no coefficients stuck on the q.

when 8 is divided by 6, you should get 8/6.

WAIT YOU ARE NOT FINISHED YET!! YOU HAVE ONE MORE STEP AND YOU WILL HAVE ANSWER.

simplify 8/6 top and bottom divided by 2 each, then you should have 4/3.
