Answer:

-9

Step-by-step explanation:

[tex](f^-^1o g^-^1)(-13)\\f^-^1(g^-^1(-13))\\g^-^1(-13) = -7[/tex]

the inverse function is essentially where the inputs and outputs are swapped

[tex]f^-^1(-7) = -9[/tex]

Answer:

51.7857143% increase is the percent increase of the price of the bicycle.

Step-by-step Explanation on finding percent increase using this question:

Formula needed:

% increase = 100 x (final-initial)/ | initial |

1. % increase = 100 x (85-56)/56

2.% increase = 100 x 29/56

3. % increase = 100 x 0.517857143

4. % increase = 51.17857143 (final answer)

Round if told by directions to do so.

Answer:

Total number of teaspoons is 2.75

Step-by-step explanation:

Here, we want to know the total number of teaspoons of spices in the dish

we can calculate this by adding together the individual number of spices

That will be ;

1/2 + 1 1/4 + 3/4 + 1/2(1/2)

1/2(1/2) represents half as much pepper as salt

1/2 = 0.5

1 1/4 = 1.25

3/4 = 0.75

1/2(1/2) = 1/4 = 0.25

The total number of tea spoons will be;

0.5 + 1.25 + 0.75 + 0.25 = 2.75

Step-by-step explanation:

Answer:

59 feet per second.

Step-by-step explanation:

Firstly, we need to convert miles into feet and hours into seconds.

We know that there are 5280 feet in a mile.

To convert hours into seconds we multiply how many minutes are in an hour by how many seconds there are in a minute (60x60) to get 3600.

We multiply 5280 by 40 to get 211200 feet per hour

Because of the word "PER" we know that this is a divison problem.

211200 divided by 3600 is 58.66 repeating. Rounded to the nearest whole number makes it 59 feet per second.

Answer:

2 hours

Step-by-step explanation:

3 miles per hour

3 x 2 = 6

Answer:

2 hours

sebastian tendia 6 manzanas

Answer:

Step-by-step explanation:

|x/-4| = 2 corresponds to two different equations:

1) -x/4 = 2 if x/-4 is already positive, and

2) x/4 = 2 if -x/4 is negative, due to the absolute value operator

In case 1, -x = 8, or x = -8

and

in case 2, x = 8

so the solution set is {-8, 8}

Double check to ensure that you have copied down this problem correctly.  Your " |x/-4| " looks odd/ambiguous

Answer:

130

Step-by-step explanation:

so you take 35+95=130

then you take 180-130=50 to get the other angle in the triangle

then to get the missing angle you do 180-50=130

so that is the missing angle

Answer:

A. 2+9=9+2

Step-by-step explanation:

Answer:

4.8 cm

Step-by-step explanation:

What we know: V= 24 cm3 and b= 5 cm2

Formula: V= bh

24cm3= (5cm2)h

4.8 cm= h

Answer:

4.4 hours

Step-by-step explanation:

Let the number of hours be represented as h

The price of Stock A 9 AM was $12.71. Since then, the price has been increasing at the rate of $0.05 each hour

$12.71 + $0.05 × h

12.71 + 0.05h

At noon the price of Stock 8 was \$13.46 . To decrease at the rate of by $0.12each hour.

$13.46 + $0.12 × h

13.46 - 0.12h

If the two rates continue, in how many hours will the prices of the two stocks be the same?

12.71 + 0.05h = 13.46 - 0.12h

0.05h + 0.12h = 13.46 - 12.71

0.17h = 0.75

h = 0.75/0.17

h = 4.41176470588 hours

Approximately = 4.4 hours

The prices of the two stocks be the same in 4.4 hours
