Given the following functions:

f(x) = x2
g(x) = 2 x - 3

Find the composition of the two functions and show your process:

f(g(x))

Answers

Answer:

f(g(x)) = 4x² - 12x + 9

Step-by-step explanation:

Substitute x = g(x) into f(x) , that is

f(g(x))

= f(2x - 3)

= (2x - 3)² ← expand using FOIL

= 4x² - 12x + 9

Rational numbers are those which can be expressed as a fraction of 2 whole numbers
(2/3 , 1/2 etc)

Irrational numbers are those that CAN NOT be expressed as a fraction of 2 whole numbers
( pi, square root of 2, etc)

*Extra notes to help differentiate*

-An irrational number has endless non-repeating digits to the right of the decimal point.

- Every whole number is a rational number, because any whole number can be written as a fraction. For example, 2 can be written as 2/1

Thomas invested $40,000. He put part of the money in an account paying 2% interest and the remainder
into stocks paying 3% interest. The total annual income from these investments was $1020. How much
did he invest at each rate?
(show work please)

Answers

Answer:

18,000 at 2%

22,000 at 3%

Step-by-step explanation:

x: the amount in account paying 2% interest

y: the amount in stock paying 3% interest

x + y = 40,000

2%. x + 3%. y = 1020

⇒ x = 18,000

y = 22,000

A new car, valued at 28,000 depreciates at 9% per year. What is the value of the car one year after purchase

Answers

Answer:

$25,480

Step-by-step explanation:

9% of 28,000 is 2,520. "Depreciates" means we must subtract. When we subtract this number from the initial value of the car which is 28,000 we get 25,480, which would be how much the car is worth after one year.

hope this helps!

So there's 2 types of depreciation you often will come across, one is compound and one is simple.

For compound : A=P(1-i)^n

For simple A=P(1-in)

NOTE: A is amount after depreciation, P is amount before depreciation, n is number of years and i is the rate of depreciation.

Now if your depreciation is compound then:

A=P(1-i)^n

A=28000(1- 0.09)^1

A= 25480

If it's simple depreciation

A=P(1-in)

A= 28000(1- 0.09x1)

A= 25480

Now these are your solutions

Answers

Answer:

x: 7, 4, 10

y: 4

Step-by-step explanation:

y = x - 3

Plug one value of x (given in the chart) to identify the value of y

One x value can be 7 (as it is shown)

so plug in 7 for x in the rule: y = x - 3

y = 7 - 3

Solve for y if y = 7 - 3

y = 4

so when x = 7, y = 4

(Keep doing this format to get every x or y value)

Ivan currently has $ 45 saved. He had been saving $ 9 each week. You spent $ 126 of those savings yesterday. How many weeks have you been saving?

Write an equation that can be used to answer the previous question. First, choose the appropriate shape. Then fill in the blanks with the numbers 45, 9, and 126. Let w be the number of weeks.

please i need the procedure of this pls

Answers

9w + 45 = 126

Ivan earns $9 per week so we would write it as 9w
Add 45 to it because that is what he also saved
Then he spent those savings which was 126.
Now we can find how many weeks he was saving for.

First minus 45 from both sides
9w = 126 - 45 = 81

The divide both sides by 9
w = 9

Ivan has been saving for 9 weeks

Bill's bike wheels have a 26-in. diameter. The odometer on his bike counts the number of times a wheel rotates during a trip. If the odometer counts 200 rotations during the trip from Bill's house to school, how many feet does Bill travel? Round to the nearest foot.

Answers

Answer:

1361 ft.

Explanation:

The circumference of the wheel times the number of rotations equals distance travelled

[tex]C = d\pi[/tex]

Answer:

≈ 1361 ft

Step-by-step explanation:

One rotation is same distance as:

C = πd = 3.14*26 = 81.64 in

Total distance traveled:

200*81.64 = 16328 in

Convert inches to feet:

12 in = 1 ft16328 in = 16328/12 ft = 1360.66666667 ft ≈ 1361 ft

calculate the quantity based the percentage given or vice versa.

Answers

Answer:  x = 35

Step-by-step explanation:  The sum of all the angles is equal to 360.

2*(x+y+5)+y+2x=360

Opposite angles are equal:  y = 2x

Substitute y=2x into the first:  4x+6x+10 = 360:  x=35 (y = 70)

From weakness to strength, or strength to weakness- And, often, back again. From health to sickness and back, we pray, to health again. From offence to forgiveness, from loneliness to love, from joy to gratitude, from pain to compassion, and grief to understanding- From fear to faith. From defeat to defeat to defeat- Until, looking backward or ahead, we see that victory lies not at some high place along the way, but in having made the journey, Stage by stage- A sacred pilgrimage. Birth is beginning, and death a destination; But life is a journey, a sacred pilgrimage made stage by stage- from birth to death to life everlasting."
