Answer 1

Answer:

Answer B

Step-by-step explanation:

Write out f(x) and g(x) in a column; we will subtract g(x) from f(x):

f(x) = x^2  - 9          or f(x)   =   x^2           - 9

-g(x) = -(2 - x)          or -g(x) =           +x      -2

                                    ---------------------------------

                                      f(x) - g(x) = x^2 + x - 11   (Answer B)

For what value of the constant c is the function f continuous on
(−∞,∞) where

f(b) = { cb + 9 if b ≤ 3
c(b)² − 9 if b > 3

Answers

9514 1404 393

Answer:

  c = 3

Step-by-step explanation:

In order for the function to be continuous at b=3, the left and right limits must be the same. In short, we must have ...

  c(3) +9 = c(3²) -9

  18 = 6c . . . . . . . . add 9-3c to both sides

  3 = c . . . . . . . . . . divide by 6

Function f is continuous when c=3.

Work out the percentage change to 2 decimal places when a price of £8.95 is increased to £10.

Answers

Answer:

The percentage change was of 11.73%.

Step-by-step explanation:

The percentage change of the increase is given by the change multiplied by 100 and divided by the initial value.

Price of £8.95 is increased to £10.

Change: 10 - 8.95 = 1.05

Initial price: 8.95

1.05*100/8.95 = 11.73%

The percentage change was of 11.73%.

A movie started at 2:30 PM. and ran for 1 Hour and 45 minutes.What time did the movie end?

Answers

Answer:

The movie ended at 4:15 PM

Step-by-step explanation:

=> It started at 2:30, when you add an hour to that it will become 3:30

=> Then you must add the 45 minutes to it

=> so it will be 3:75, however that is not a right answer and it is not logical

=> so you need to add the first 30 minutes which will give you 4:00

=> then add the rest which is 15 minutes

therefore, your answer is 4:15 PM

hope this helps and i hope it is not too confusing :)

9 exits. How many exits are
there altogether?

Answers

Answer:

51

Step-by-step explanation:

There are 14 movie theaters, and 3 exits each.

You can multiply 14 by 3 to get the number of exits in the movie theaters combined.

Next, the food area has 9, so you add 9 to the 42.

42 + 9 = 51.

55% of what number is 1100? Which of the following proportions could be used to

Step-by-step explanation:

Hope it is helpful...

The required value of unknown number a would be 2000.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

WE need to determine 55% of what number is 1100.

Let the unknown number is a. then we get;

55% of a = 1100

55/100 of a = 1100

55/100 x a = 1100

Cross mulitiplication, we get;

55a = 1100 x 100

55a = 110000

Divide by 55, we have;

a = 110000/ 55

a = 10000/ 5

a = 2000

Therefore, the required value of unknown number a would be 2000.

Which equation represents the line that has a slope of 4 and passes through the points (2,7)

Answers

Answer:

The answer is y = 4x - 1.

Step-by-step explanation:

The answer is y = 4x - 1.

Step-by-step explanation:

☆The equation we'll be using: y = mx + b

☆Since we already have the slope. we have to find the y-intercept.

☆\begin{gathered}y = mx + b \\ \\ 7 = 4(2) + b \\ 7 = 8 + b \\ \frac{ - 8 = - 8 \: \: \: \: \: \: \: \: \: \: \: }{ - 1 = b \: \: \: \: \: \: \: \: \: \: } \end{gathered}

y=mx+b

7=4(2)+b

7=8+b

4x-3y = 12 and 3x+2y =6

Answers

Answer:

x = 42/17

y = -12/17

Step-by-step explanation:

4x - 3y = 12

3x + 2y = 6

use the elimination method (definition at the bottom of the page)

multiply both sides of the equation 4x - 3y = 12 by 2

8x - 6y = 24

multiply both sides of the equation 3x + 2y = 6 by 3

9x + 6y = 18

now, add the two equations:

17x = 42

x = 42/17

now, plug this into the equation 3x + 2y = 6

126/17 + 2y = 6

2y = -24/17

y = -12/17

To find x, we make use of:

In this case, it is:

[tex]cos(36) = \frac{x}{38}[/tex]

Multiply both sides by 38

What is the slope of a line perpendicular to a line which has a slope of -2

Answers

Answer:

it is 1/2

Step-by-step explanation:

The product of a lines slope M and the slope K of a perpendicular is -1:

M*K=-1

This implies

K=-1/M

since

M * -1/M=-1

In our example we are given a line of slope M=-2 therefore the slope K of a line to perpendicular to this line is:

M*K=-1

-2*K=-1

K=-1/-2=1/2
