Answer:

Step-by-step explanation:

f(x) = 4^x

g(x) = f(x -1) + 3

g(x) = 4^(x - 1) + 3

See the diagram that is below.

Red line: f(x) = 4^x

Blue line: g(x) = f(x - 1) + 3

The graph has been transformed so that f(x) moves upwards by 3 unitsw to get to g(x)

Furthermore,  if x = 0 the y intercept for f(x) = 1

If x = 0 then g(x) moves up 3 spaces by virtue of the 3, and and up another 1/4 because the first term becomes 4^-1 = 1/4. This 1/4 gets added to the 3 to give 3 1/4

Answers

Answer:

5/6 cups of chocolate chips

Step-by-step explanation:

According to a recipe , 2 1/2 * c * u * p chocolate chips are needed to make a large batch of cookies. Manuel decided to make only 1/3 of the cookies . How many cups of chocolate chips will Manuel need ?

From the above question:

1 batch of cookies = 2 1/2 cups of chocolate chips

1/3 batch of cookies = x

Cross Multiply

x = 1/3 × 2 1/2

x = 1/3 × 5/2

x = 5/6 cups of chocolate chips

Hence, Manuel would need 5/6 cups of chocolate chips for 1/3 bath of cookies.

Given that a = 4.8 × 104 and that b = 8 × 10−3
Calculate the following, expressing each answer in standard form. Working must be shown
i) ab
2

Answers

Answer:

3.84 * 10^0

Step-by-step explanation

Given the following values;

a = 4.8 × 104 and that b = 8 × 10−3

We are to find the product ab

ab = (4.8 × 10^4)(8 × 10^−3)

ab = (4.8*8)(10^4 * 10^-3)

ab = 38.4 * 10^(4-3)

ab = 38.4 * 10^-1

ab = 3.84 * 10 * 10^-1

ab = 3.84* 10^0

Hence the product in standard form is expressed as 3.84 * 10^0

A 42-inch piece of steel is cut into 3 pieces so that the 2nd piece is twice as long as the 1st piece, and the 3rd piece is 2 inches more than 5x the length of the first piece. Find the lenth of the pieces.

Answers

Answer:

1st piece = Piece A = 5 inches

2nd piece = Piece B = 10 inches

Third Piece = Piece C = 27 inches

Step-by-step explanation:

A 42-inch piece of steel is cut into 3 pieces

Let the lengths be represented as:

1st piece = Piece A

2nd piece = Piece B

Third Piece = Piece C

Hence:

A + B + C = 42

The 2nd piece is twice as long as the 1st piece

B = 2A

The 3rd piece is 2 inches more than 5 times the length of the first piece.

C = 5A + 2

Hence: we substitute

A + B + C = 42 inches

A + 2A + 5A + 2 = 42 inches

8A = 42 - 2

8A = 40 inches

A = 40 inches/8

A = 5 inches

Solving for B

B = 2A

B = 2 × 5 inches

B = 10 inches

Solving for C

C = 5A + 2

C = 5 × 5 + 2

C = 25 + 2

C = 27 inches

Therefore, the lengths of the 3 pieces =

1st piece = Piece A = 5 inches

2nd piece = Piece B = 10 inches

Third Piece = Piece C = 27 inches

Answer:

if you use the information down below you should be able to get every answer. just make sure you match the lines correctly. HUGE HINT=

XZ=YO

MO= 2(Z0)

ZO= 1/2(NO)

Step-by-step explanation:

Well since we know X is the midpoint of segment MN we can say half of line X equals 6.2

With that info we have to length to each triangle base which is 6.2

We also see that line NO is 18 so YO equals 9

ALSOOO, XY=10, which makes ZO equal 10

We now have all the lengths to each side

MX (BASE)=6.2     YO=9         ZO=10

Kelsey's preschool tuition is $180 per week. She receives a small discount for the honor roll, $50 per month. Her grandparents help out and pay 20% of her tuition. How much do her grandparents pay?

Answers

Answer:

The answer is $104.

Step-by-step explanation:

So take away the discount which is $50. That leaves $130. Then do the percentage decrease which is 130 minus 20%. The answer to that is $26. Her grandparents pay $104. (I'm really not sure of my answer though).

Her grandparents pay $104.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Kelsey's preschool tuition is $180 per week.

She receives a small discount for the honor roll, $50 per month.

Her grandparents help out and pay 20% of her tuition.

Kelsey's tuition fee after discount= 180- 50 = $130

and, Her grandparents pay = 130- 130 x 0.2 = 130- 26= $104

Hence, Her grandparents pay $104.

Kathy works in a law office. Her annual salary is $42000. Kathy is paid monthly and pays an income tax rate of 20% on her earnings over $1000, plus $53.50. How much income tax does Kathy pay each month?​

Answers

Answer:

$8,453.50

Step-by-step explanation:

Annual salary = $42000

Income tax rate = 20% on her earnings over $1000 + $53.50

Income tax = 20% of $42000 + $53.50

= 20/100 × 42,000 + 53.50

= 0.2 × 42,000 + 53.50

= 8,400 + 53.50

= $8,453.50

Income tax = $8,453.50

Answer:

42000 divided by 12 =  3500

3500 - 1000 = 2500

2500=20100

x = 500 + 53.50

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Using the formula

I = Prt

here

P = The principle

t = Time in years

I = Simple interest

r = Annual interest rate

Let us fill the table using the formula:

I = Prt

ROW ONE:

Given

P = $100

r = 5% = 0.05

t = 3

Determine:

I = ?

Using the formula

I = Prt

I = 100 × 0.05 × 3

I = $15

ROW TWO:

Given

P = $500

r = 4% = 0.04

I = $20

Determine:

t = ?

Using the formula

I = Prt

20 = Prt

20 = 500 × 0.04 × t

t = 20 / (500 × 0.04)

t = 20 / 20

t = 1 year

ROW THREE:

Given

t = 7

r = 10% = 0.1

I = $35

Determine:

P = ?

Using the formula

I = Prt

35 = P(0.1) (7)

P = 35 / (0.1×7)

P = $50

ROW FOUR:

Given

P = $200

t = 2 years

I = $6

Determine:

r = ?

Using the formula

I = Prt

6 = 200 × r × 2

r = 6 / (200×2)

r = 6 / 400

t = 0.015

t = 1.5%             ∵ 1.5% = 0.015

Do you mean something divided by 100 equals 20? If so the answer is 3080

Step-by-step explanation:

110 divided by blank is equal to 28. To solve this you have to take 110 and multiply it by 28 the reason is because multiplication is the averse of division which gives you 3080. If you would like you could use a calculator and divided 110 from 3080.

The result of division is 3.928.

Thus 110 divided by 3.928 = 28

Given, 110 divided by _ = 28 .

Division property:

The rules for division are:

(1) positive ÷ positive = positive

(2) positive ÷ negative = negative

(3) negative ÷ negative = positive

Apply rule 1 as the numbers are positive.

Answers

Answer:

a. Function; every x-value corresponds to only 1 y-value

b. Not a function; doesn't pass the VLT

c. Function, passes the VLT

2.

a. -200

b. x= -22.5

Step-by-step explanation:

Here is the basic rule for a function:

Every input (x) value goes only to one output (y) value.

For example, an x-value of 4 cannot go to y-values of both 2 and 4. {(4,2), (4,4)

a.

In a, we see that every x value has only one line- no x-value goes to two different y values, therefore, a is a function.

b. Remember that every x-value can only have one matching y value. This definition allows us to do a special test called the vertical line test (VLT). If we pass a vertical line through a graph (|) and it doesn't pass through two points at the same x value, then that graph is a function.

However, in this graph we can clearly see that this function DOES NOT pass the VLT.

(-2, 2) and (-2,-3)

c.

We're going to use the VLT once again. If we put a vertical line through the observable graph does any x value appear to have two or more y-values? No, so this is the graph of a function

So, g(x) = 106 and they want you to determine x.
