?????????????????????

Answers

1) Option A

F = m*a This is the second Law of Newton

2) option J

d = √ [a^2 + b^2 ]

That is the application of Pythagorean theorem, which applys for right triangles.

3) Use sine ratio

sin (30°) = opposite-leg / hypotenuse

=> opposite-leg = hypotenuse * sin(30°)

opposite-leg = f(h)

hypotenuse = h

sin(30°) = 1/2

=> f(h) = h * 1/2

=> option c. f(h) = (1/2)h

4) The formula for the volume of a cylinder is V = area of the base * height

Here area of the base = π(r^2)

height = 2r

=> V (r) = 2π(f^3) <----- option G.

5) The slope - y -intercept function of the line is y = mx + b where m is the slope and b is the y-intercept.

In this problem m = c and b = d

So, the answer is y = cx + d <------ option B.

6) Use the formula speed = distance / time => time = distance / speed

=> f(x) = x / m < ------ option J

7) Use the equation of the distance

distance^2 = (x - x1)^2 + (y - y1)^2

given y = 2x + 7 and (x1,y1) = (3,0)

=> distance^2 = (x - 3)^2 + ( 2x + 7 - 0)^2

=> distance^2 = (x - 3)^2 + (2x + 7)^2

=> f(x) = √ [ (x - 3)2 + (2x + 7)^2 ] <------- option D

Molly bought a case of bottled water at the store. The case contains 48 bottles. Molly knows that she will drink 3 bottles of water each day and plans to restock her supply of water once she has fewer than 10 bottles left. Determine which inequality is used to find the number of days, x, before Molly will need to restock her supply of bottled water

Answers

Let x = number of days before Molly will need to restock
48 - 3x < 10 we use is less than because "has fewer than"

If you solve this inequality by subtracting 48, then dividing by -3 (switch inequality sign), you get x > 12[tex] \frac{2}{3} [/tex]

Jon makes $78 in 12 hours of work for his mom. how much would jon make in 20 hours of work

Answers

$ 78 in 12 hrs....78/12 = 6.50 per hr

for 20 hrs...
6.50 * 20 = $ 130 <==

Answer:

$130

Step-by-step explanation:

This is a direct proportionality between the amount he makes and the time worked. As the time increases, so does the amount he makes and vice versa.

Let the amount made be A and the time T

A ∝ T,

A = KT where K is the constant of proportionality

where Jon makes $78 in 12 hours of work, A = 78, T = 12

78 = 12K

K = 6.5

A = 6.5T

In 20 hours of work, T = 20

A = 6.5 × 20

A = $130

________________________________________________________

Answer: 2 X 3 X 5 X 7

Step-by-step explanation:

The given number to find the prime factorization =210

We know that 210 can be written as [tex]21\times10[/tex]

Also , 21 can be written as [tex]3\times7[/tex].

And 10 can be written as [tex]2\times5[/tex]

Then , the prime factorization of 210 is given by :-

Hello! The volume of a sphere is 4/3πr³. The radius is 3. 3³ is 27. 27/1 * 4/3 is 108/3 or 36 in simplest form. When you do that, you're left with 36π. The answer is B: 36π cubic inches.

Answer: B) [tex]36\pi \text{cubic inches}[/tex]

Step-by-step explanation:

We know that the volume of a sphere is given by :-

[tex]\text{Volume}=\dfrac{4}{3}\pi r^3[/tex], where r is radius of the sphere.

Given : The radius of the sphere = 3 inches

Then , the volume of the sphere will be :-

[tex]\text{Volume}=\dfrac{4}{3}\pi (3)^3\\\\\Rightarrow\ \text{Volume}=36\pi \text{ cubic inches}[/tex]

Hence, the volume of the sphere = [tex]36\pi \text{ cubic inches}[/tex]

The shapes are given as:

A. Triangle

B. Circle

Rotating a circle about its axis would form a sphere, while a square would be rotated to form a cylinder.

23-17=6
The percentage of increase:
(6/17)*100=35.2942%

The value increase= 23-17

The percentage is for 100%
Thus, the increase divided by the original value, gives you the answer.
So, 6/23 x 100% is equal to 26.08%

Your business borrowed 10 bitcoins on May 1, when 1 bitcoin was worth $1,418.86. On June 1, 1 bitcoin was worth $2,441.29. Not counting the 1 month of interest, what is the total amount, including the principal, your business owed on June 1, in dollars?

Answers

Final answer:

The business owed a total of $24,464.43, including the principal, on June 1.

Explanation:

To calculate the total amount your business owed on June 1, we need to find the value of the borrowed bitcoins in dollars on that date.

Step 1: Convert the number of borrowed bitcoins to dollars on May 1 by multiplying it by the value of 1 bitcoin in dollars: 10 bitcoins * $1,418.86/bitcoin = $14,188.6.

Step 2: Convert the value on May 1 to the value on June 1 by multiplying it by the change in the value of 1 bitcoin:

$14,188.6 * ($2,441.29/$1,418.86)

= $24,464.43.

Therefore, your business owed a total of $24,464.43, including the principal, on June 1.

The total amount owed on June 1, not counting the 1 month of interest, is $24,412.90.

To calculate the total amount owed on June 1, we need to multiply the number of bitcoins borrowed by the value of one bitcoin on that date.

On May 1, the business borrowed 10 bitcoins, and the value of one bitcoin on June 1 was $2,441.29. Therefore, the total amount owed on June 1, excluding interest, is calculated as follows:

Number of bitcoins borrowed = 10

Value of one bitcoin on June 1 = $2,441.29

Total amount owed on June 1 (in dollars) = Total amount owed on June 1 (in dollars) = [tex]10 \times $2,441.29[/tex]

Total amount owed on June 1 (in dollars) = $24,412.90

Thus, the total amount owed on June 1, not counting the 1 month of interest, is $24,412.90.

(4d-8/6d) + 2/3 = 1
Multiplying both sides by 6d

A population of rabbits is growing exponentially. The function f(x) = 5(2)t models the number of rabbits after t months.

Based on the model, what is the growth factor for the population of rabbits?

Answers

13 months

Tell me if its right...

Answer:

The growth factor is '2'

Step-by-step explanation:

Here, the given function that represents the population of the rabbits that is increasing exponentially,

[tex]f(x)=5(2)^t----(1)[/tex]

Since, the growth factor is a multiplier that increases the value per period,

Also, in an exponential growth function,

[tex]y=ab^x[/tex]

b is called the growth factor where x is a variable,

Since, in function (1) t is a variable ( time in months )

By comparing, b = 2,

Hence, the growth factor is 2 for the given function.
