The Volume of cylinder represented by the option B.

According to the statement

we have given that the volume formula of cylinder is V= (pi)r^2h, and we have to find that the which expression verify the volume formula for the cylinder given in diagram.

So,

We know that height of the cylinder is given by h = 2x + 7 and

radius r = x - 3.

We know that the formula of volume of cylinder is:

Volume of a cylinder = (pi)r^2h

and Substituting the given values in the above formula

And the volume becomes

Volume = (pi)r^2h

Volume = (pi)( x-3 )^2 (2x+7)

Volume = (pi) ( x^2 + 9 - 6x ) (2x+7)

Volume = (pi) ( 2x^3 + 7x^2 +18x +63 - 42x)

So, The Volume of cylinder represented by the option B.

Question:

The volume of a cylinder is given by the formula V= pi^2h, where r is the radius of the cylinder and h is the height: which expression represents the volume of this cylinder?

a) Volume = (pi) ( 3x^3 + 7x^2 +14x +63 - 42x)

b) Volume = (pi) ( 2x^3 + 7x^2 +18x +63 - 42x)

c) Volume = (pi) ( 7x^3 + 7x^2 +11x +63 - 42x)

d) Volume = (pi) ( 11x^3 + 7x^2 +13x +63 - 42x)

Okay... so the y intercept it automatically 9. so that's out of the way. Now you narrow it down to a or b. the first number, with x is -3x. Thats your slope. easy as that

What is the equation of the line that passes through point 5,8 and has a y-intercept of -2
Bess [88]

Answer:

y = 2x - 2

Step-by-step explanation:

y = mx + b

Sub x = 5, y = 8, and b = -2 into the equation.

8 = 5m - 2

Isolate the m-term and solve for m.

8 + 2 = 5m -2 + 2

10 = 5m

Divide both sides by 5 to isolate m.

m = 2

Sub the parameters (m and b) into the template to get your equation.

y = 2x - 2

Mariana solved the equation below. Identify her ERROR and EXPLAIN what she did wrong. -3(2x-4)=-12 -6x-12=-12 -6x=0 x=0
nydimaria [60]

Answer:

Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead

Step-by-step explanation:

Mariana workings:

-3(2x - 4) = -12

-6x - 12 = -12

Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead

-6x = 0

x=0

Correct workings:

-3(2x - 4) = -12

-6x + 12 = - 12

-6x = -12 - 12

-6x = -24

x = -24/-6

x = 4

Suppose ancient Romans had a 0.2 chance of dying in each of the following age intervals: [0, 2], [2, 10], [10, 30], [30, 70] and
Pani-rosa [81]
<span>65 As for the reason the average life expectancy of a Roman who reaches the age of 30 being so much higher than the average expectancy overall, that's simply a matter of taking the average of 50 and 80, verses the average of 1,6,20,50,80. Let's illustrate that by calculating the average life expectancy of a Roman at birth, and after age 30. For birth, there's 5 ranges, each of which has the same probability. They are [0,2]: Midpoint = 1. Probability = 0.2. Product = 1*0.2 = 0.2 [2,10]: Midpoint = 6. Probability = 0.2. Product = 6*0.2 = 1.2 [10,30]: Midpoint = 20. Probability = 0.2. Product = 20*0.2 = 4 [30,70]: Midpoint = 50. Probability = 0.2. Product = 50*0.2 = 10 [70,90]: Midpoint = 80. Probability = 0.2. Product = 80*0.2 = 16 Sum = 0.2 + 1.2 + 4 + 10 + 16 = 31.4 But upon reaching 30, there is no longer a mere 0.2 probability for those last 2 slots. The chart looks like [30,70]: Midpoint = 50. Probability = 0.5. Product = 50*0.5 = 25 [70,90]: Midpoint = 80. Probability = 0.5. Product = 80*0.5 = 40 Sum = 65 If you look at each possible range of ages, the actual life expectancy is at birth: 31.4 years after age 2: 39 years after age 10: 50 years after age 30: 65 years after age 70: 80 years</span>
