Answer:

11 ft

Step-by-step explanation:

The equation for the volume of a cone is:

V = 1/3(3.14)r^2h

V = 414.48

r = 6

Plug in those values and solve for h:

414.48 = 1/3(3.14)(6)^2h

414.48 = 37.68h ; divide both sides by 37.68

11 = h

The missing height is 11ft.

Jake is 2 5 25 years old. Next year, he'll be 2 6 26 years old. What is the percentage increase in Jake's age from last year?

Answer:

Step-by-step explanation:

We have been given that Jake is 25 years old. Next year, he'll be 26 years old.

To find the percentage increase in Jake's age from last year, we will use percentage decrease formula as our original value is less than new value.

$\text{Percentage decrease}=\frac{\text{Original-New}}{\text{Original}}*100$

Now let us substitute our given values in above formula.

$\text{Percentage decrease in Jake's age from last year}=\frac{25-26}{25}*100$

$\text{Percentage decrease in Jake's age from last year}=\frac{-1}{25}*100$

$\text{Percentage decrease in Jake's age from last year}=-1*4=-4$

Since our answer is a negative number then this is a percentage increase.

Therefore, there is 4% increase in Jake's age from last year.

Convert the following to standard form, then write

Ivahew [28]

Answer:

$f(x)=x^2+6x+9$

Step-by-step explanation:

We are required to represent the expression given in the standard form to the quadratic form

Given

$f(x) = (x + 3)^2$

let us square the given expression

f(x)=(x+3)(x+3)

open brackets

$f(x)=x^2+3x+3x+9$

sum the similar terms

$f(x)=x^2+6x+9$

Fill in the blank spaces please.

Kisachek [45]

PART A

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

So for 2 pounds, it would cost $5.00

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

For the 1 pound one, it would cost $2.50

PART B

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb
