What does the value 3 mean in this function?

A. On the first day, 3 leaves fall.

OB. On the second day, 3 leaves fall.

C. The number of leaves that fall on a given day is 3 times the number of leaves that fell on the first day.

D. The number of leaves that fall on a given day is 3 times the number of leaves that fell on the previous day.

C. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the first day.

D. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the previous day.

Answers

Answer:

A. On the first day, 3 leaves fall.

B. D. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the previous day.

Step-by-step explanation:

Given

[tex]f(n) = 3(2)^n[/tex]

Solving (a) The meaning of 3.

3 represents the initial number of leaves (i.e. the first day) and this proved as follows.

On the first day, n = 0.

Substitute 0 for n in [tex]f(n) = 3(2)^n[/tex]

[tex]f(0) = 3(2)^0[/tex]

[tex]f(0) = 3*1[/tex]

[tex]f(0) = 3[/tex]

Solving (b) The meaning of 2.

2 represents the rate which leaves fall down.

In (a)

[tex]f(0) = 3[/tex]

Take n = 1

Substitute 1 for n in [tex]f(n) = 3(2)^n[/tex]

[tex]f(1) = 3(2)^1[/tex]

[tex]f(1) = 3*2[/tex]

[tex]f(1) = 6[/tex]

When f(1) is divided by f(0), the result 2. So, the number of leaves doubles everyday

A checkbook balance sheet shows an initial balance for the month of $300. During the month, checks were written in the amounts of $25, $82, $213, and $97. Deposits were made into the account in the amounts of $84 and $116. What was the balance at the end of the month?

Answers

Answer:

your answer  is 200 if you add 84 and 116 but is you add 25 82 213 and 97 it will be 417

Step-by-step explanation:

The balance at the end of the month is $83.

Checkbook balance = $300

Amount withdrawn = $25 + 82 + $213 + $97 = $417

Amount deposited = $84 + $116 = $200

Therefore, the balance at the month end will be:

= $300 - $417 + 200

= $83

simplify fully 4x-8x^2/12x-6

Answers

Answer:

- [tex]\frac{2}{3}[/tex] x

Step-by-step explanation:

Given

[tex]\frac{4x-8x^2}{12x-6}[/tex] ← factorise numerator and denominator

= [tex]\frac{4x(1-2x)}{6(2x-1)}[/tex] ← factor out - 1 from (1 - 2x) on numerator

= [tex]\frac{-4x(2x-1)}{6(2x-1)}[/tex] ← cancel the common factor (2x - 1)

= [tex]\frac{-4x}{6}[/tex] ← cancel 4 and 6 by 2

= - [tex]\frac{2}{3}[/tex] x

Simplifying the expression will give us: [tex]\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}[/tex]

Given the expression, [tex]\frac{4x-8x^2}{12x-6}[/tex], we are required to simplify the expression as follows:

Step 1: Factorize the denominator and the numerator.

[tex]\frac{4x-8x^2}{12x-6}\\\\=\frac{(1 - 2x)4x}{(2x - 1)6}[/tex]

Step 2: Rewrite the fraction by factoring out -1 from the numerator.

[tex]=\frac{(2x - 1)-4x}{(2x - 1)6}[/tex]

Step 3: Divide the numerator and denominator by (2x - 1) respectively.

[tex]=\frac{-4x}{6}[/tex]

Step 4: Divide the numerator and denominator by 2 respectively.

[tex]=\frac{-2x}{3}[/tex]

Therefore, simplifying the expression will give us: [tex]\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}[/tex]

2. If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is needed to cover the entire wall?
A) 8 2/3 gallons
B) 8 1/3 gallons
C) 3 gallons
D) 2 gallons

Please help !

Answers

Closest answer would be

C.) 3 gallons

Answer: 4 gallons.

Step-by-step explanation:

With this equation, we can use the ratio 1/2 : 1/8. For every 1/2 gallon of paint, 1/8 of a wall is painted.

If 1/2 gallons covers 1/8 of a wall, then we need 8 of the 1/2 gallons to cover the whole wall. We canrepresent this by multiplying 8 and 1/2.

8 x 1/2 = 4.

Because of this, 4 gallons of paint are needed to cover he entire wall.

(Quick note: I don't know why, but the answer choices seem kind of weird. But the answer is 4 :])

Increase £120 by 35%

Answers

Answer:

£162

Step-by-step explanation:

Let's first find 35% of £120.

35% here is our multiplier, so we can turn it into a decimal (0.35) in order to use it in our sum.

£120 × 35% = £42

Now add £42 to £120.

£120 + £42 = £162

Super simple!

£162

explanation:
50% of 120= 60
5% = 6
30% = 36
35%= 36+6= 42

If we had a Pyramid with a hexagonal base, how many of these pyramids would it take to fill up a hexagonal Prism with a congruent base, and equal height?

Answers

Answer:

3 of the pyramids

Step-by-step explanation:

Given:

Hexagonal Prism

Hexagonal based pyramid

Required

How many of the pyramid will fill up the prism

To do this, we start by calculating the volumes of both shapes.

Let V1 be the volume of the hexagonal prism

[tex]V_1 = \frac{3\sqrt{3}}{2}a^2h[/tex]

Where: a = base and h = height

Let V2 be the volume of the hexagonal based pyramid

[tex]V_2 = \frac{\sqrt{3}}{2}a^2h[/tex]

Where: a = base and h = height

The number of the pyramid that can occupy the prism is calculated by dividing V1 by V2

[tex]Number = \frac{V_1}{V_2}[/tex]

[tex]Number = \frac{3\sqrt{3}}{2}a^2h /\frac{\sqrt{3}}{2}a^2h[/tex]

Convert division to multiplication

[tex]Number = \frac{3\sqrt{3}}{2}a^2h * \frac{2}{\sqrt{3}a^2h}[/tex]

[tex]Number = \frac{3\sqrt{3}}{2} * \frac{2}{\sqrt{3}}[/tex]

[tex]Number = \frac{3\sqrt{3}}{1} * \frac{1}{\sqrt{3}}[/tex]

[tex]Number = \frac{3*1}{1} * \frac{1}{1}[/tex]

[tex]Number = 3[/tex]
