C) 1215 cm
D) 67.5 cm

Answers

Answer 1
Answer:

Answer:

953.775cm³

Step-by-step explanation:

V=  πr²h

V= 22/7x 4.5²x 15 = 3.14 x303.75 = 953.775cm³

Answer 2
Answer:

Answer:

Volume of the cylinder = 953.775

Given that a rectangular yard has dimensions length = 8x-3 and width 2x+6 determine the perimeter of the yard

Answers

Answer:

The perimeter of rectangular yard is 20 x + 8   yard

Step-by-step explanation:

Given as :

The length of the rectangular yard = L = 8 x - 3   yard

The width of the rectangular yard = w = 2 x + 6   yard

Let The perimeter of rectangular yard = p yard

According to question

Now, The perimeter of rectangular yard is given as

Perimeter = 2 × Length + 2 × width

Or, p =  2 × L + 2 × w

Or, p = 2 × (8 x - 3) + 2 × (2 x + 6)

Or, p = 16 x - 6 + 4 x + 12

Or, p = (16 x + 4 x) + (12 - 4)

Or, p = 20 x + 8   yard

So, The perimeter of rectangular yard = p = 20 x + 8   yard

Hence The perimeter of rectangular yard is 20 x + 8   yard    Answer

a. Find the number of coffee shops in

2004.

b. If the trend described by the model​ continues, predict the year after 2000 in which the number of coffee shops will be 26,500.

a. The number of coffee shops in 2004
was

 

Answers

Answer:

a. 9161

b. 2011

Step-by-step explanation:

The number of coffee shops in the country can be modeled as by the function: f(x) = 110x² + 746x + 4417, where f(x) is the number of coffee shops and x is the number of years after 2000.

a. Now, in 2004, the x value is (2004 - 2000) = 4.

Therefore, f(4) = 110 × 4² + 746 × 4 + 4417 = 9161

So, the number of coffee shops in 2004 is 9161.

b. If f(x) = 26500, then we have to find the value of x.

So, 110x² + 746x + 4417 = 26500

⇒ 110x² + 746x - 22083 = 0

Applying the Sridhar Achaya formula to find x,

{Neglecting the negative roots as x can not be negative}

⇒ x = 11.17 years.

If ax² + bx + c = 0, then Using the Sridhar Acharya Formula, we can write

and

Therefore, in 2011 the number of coffee shop will be 26500.

o f^-1(x)= -1/5x
o f^-1(x) = 1/5x
o f^-1(x) = 5x

Answers

Answer:

Third choice

Step-by-step explanation:

They are asking us to find the inverse of y=5x. To do this you just switch x and y and then remake y the subject of the equation (solve for y.)

y=5x

x=5y (I switch x and y)

x/5=y ( I divided both sides by 5)

Then you just replace y with the f^-1(x) thing

f^-1(x)=x/5

or

f^-1(x)=1/5x
