Mathematics

Answer:

vol of cylinder = per. of base x height + 2 (area of base)

area of base = pi x r^2

4pi = pi r^2

4=r^2

r=2

per of base = 2 x pi x r

2xpix2=4pi (same as area cause 2x2 and 2^2 is the same thing)

4pi + 2(4pi)

4pi + 8pi

12pi = volume

So far, Ricardo has scores of 13, 17, 19 and 21 points for the first four rounds of a dice game. What does he need the total sco

posledela

Answer:

40 points

Step-by-step explanation:

The score for the first four rounds of the game is 13, 17, 19, and 21 points.

Let $S_5$ and $S_6$ be the scores of the fifth and sixth games respectively in order to achieve an average score of 20 points per round for all six rounds.

$\text{Average score} = \frac{\text{Sum of the scores of all the rounds}}{\text{Total number of the rounds}}$

$\Rightarrow 20=\frac{13+17+19+21+S_5+S_6}{6}$

$\Rightarrow 20\times6=80+S_5+S_6$

$\Rightarrow S_5+S_6=120-80=40.$

Hence, the combined score of the fifth and sixth rounds are 40 points.

Identify the coefficients, terms, like terms, and constants in

igor_vitrenko [27]

$\huge\boxed{\sf{Hello. :D}}$

The coefficient is a number before a variable.

Here, the coefficient is 9.

The like terms are any terms that have the same variable.

Here, 9k and -k are like terms, and 7 and 4 are like terms as well.

Combine like terms:

8k+3

The constants are: 7 and 4 (Constants are numbers in an expression or equation)

After combining like terms, the constant became

Let f(x) = 5x – 8 and g(x) = 9 - 6x2. - (f o g)(-3) =

MArishka [77]

Step-by-step explanation:

f(x) = 5x - 8

g(x) = 9 - 6x²

= (fog)(-3)

= f( g(3) )

= 5x - 8

= 5(9 - 6x²) - 8

= 5(9 - 6(-3)² ) - 8

= 5(9 - 54) - 8

= 5(-45) - 8

= -225 - 8

= -233

(fog)(-3) = -233
