f(r)=3.14r2 what is f(7)?

Hi :)

f(r) = 3.14r2

f(7) = 3.14(7)(2)

f(7) = 43.96

please help this 2 sums

**Answer:**

**Step-by-step explanation:**

Sin (A + B) = Sin A *Cos B + Cos A *Sin B

Sin 75 = Sin (30 + 45)

= Sin 30 * Cos 45 + Cos 30 * Sin 45

[tex]= \dfrac{1}{2}*\dfrac{1}{\sqrt{2}}+\dfrac{\sqrt{3}}{2}*\dfrac{1}{\sqrt{2}}\\\\\\= \dfrac{1}{2\sqrt{2}}+\dfrac{\sqrt{3}}{2\sqrt{2}}\\\\= \dfrac{1+\sqrt{3}}{2\sqrt{2}}[/tex]

**Answer:**

x = -4

**Step-by-step explanation:**

-2(3x - 4) - x - 3 = 33

~Simplify

-6x + 8 - x - 3

-7x + 5 = 33

~Subtract 3 to both sides

-7x = 28

~Divide -7 to both sides

x = -4

Best of Luck!

**Answer:**

x = -4

**Step-by-step explanation:**

-2(3x - 4) - x - 3 = 33

*solve the brackets first*

-6x + 8 -x -3 = 33

-6x - x + 8 - 3 = 33

-7x + 5 = 33

-7x = 33-5

-7x = 28

x = 28/ -7

x = -4

A small bag of 12 tiny potatoes costs 8.78........ how much does one potato cost?

one potato cost 73 cents because 8.78 divided by 12 = 0.73

Price divide amount of product

8.78 / 12 = 0.713666…

The answer should be 0.71, because money must be in 2 decimal place

8.78 / 12 = 0.713666…

The answer should be 0.71, because money must be in 2 decimal place

Russell decides to make a tile pattern after the first day his pattern has 8 tiles after the fourth day it has 35 tiles how many tiles was pattern have after the fifth day?

**Answer:**

44

**Step-by-step explanation:**

n = pattern number

9n - 1 = number of tiles

Number 5 = 9n - 1

= 5 x 9 - 1

= 45 - 1

= 44

The **pattern** will have 54 tiles after the fifth day

To determine the pattern, let's find the difference between the number of tiles on consecutive days:

Difference between Day 2 and Day 1: 8 tiles - 0 tiles = 8 tiles

Difference between Day 3 and Day 2: 20 tiles - 8 tiles = 12 tiles

Difference between Day 4 and Day 3: 35 tiles - 20 tiles = 15 tiles

Notice that the difference between the number of tiles on consecutive days is increasing by 4 each time (8, 12, 15).

Now, let's use this **difference** to find the number of tiles after the fifth day:

Difference between Day 5 and Day 4: 15 tiles + 4 tiles = 19 tiles

Number of tiles after the fourth day: 35 tiles

Number of tiles after the fifth day: 35 tiles + 19 tiles = 54 tiles

So, the pattern will have 54 tiles after the fifth day.

i really need to find out how to find a,b, and c in the quadratic formula can u please help ASAP will mark as BRAINLIEST!!

**Answer:**

*Brainliest, please! (Answer below)*

**Step-by-step explanation:**

The basic form for any quadratic function is:

ax^2 + bx + c.

The constant of the 1st term, the x^2 constant, is a, the constant of the second term, the x constant, is b, and the constant, the third term, is c. There are some instances where there will not be a b or c. For example, x^2 + 2, or 3x^2 - 4x. However, there must always be an a, or else the function isn't quadratic.

Carson buys eggs and lemons at the store.

He pays a total of $39.62.

He pays $6.74 for the eggs.

He buys 8 bags of lemons that each cost the same amount.

Which equation could be used to determine xx, how much each bag of lemons costs?

**Answer:**

8x = 39.62 - 6.74

**Step-by-step explanation:**

Cost of 1 bag of lemons = $ x

Cost of 8 bags of lemons = 8 *x = 8x

Cost of 8 bags of lemons = Total cost - cost of the eggs

8x = 39.62 - 6.74

**Answer:**

3.

**Step-by-step explanation:**

[tex]x + y = 39.62 \\ x = 6.74 \\ y = \frac{39.62 - 6.74}{8} [/tex]

The answer is 19 due to the pattern increasing in one for each number

**Answer:**

19, 25, 32

**Step-by-step explanation:**

Find the difference within each number:

5 -> 7: + 2

7 -> 10: + 3

10 -> 14: + 4

With each difference, + 1 is added so we can infer the next difference will be + 5.

14 + 5 = 19

Next is + 6.

19 + 6 = 25

Now + 7.

25 + 7 = 32
