Please Help.. A Sphere And A Cylinder Have The Same Radius And Height. The Volume Of The Cylinder Is

Answers

Answer 1

9514 1404 393

Answer:

  (d)  2/3(11)

Step-by-step explanation:

The height of the cylinder is h=2r, so the volume of the cylinder in terms of radius is ...

  V = πr^2·h = πr^2·(2r) = 2πr^3

The volume of the sphere is given by the formula ...

  V = (4/3)πr^3

So, the ratio of the sphere volume to the cylinder volume is ...

  sphere volume / cylinder volume = ((4/3)πr^3)/(2πr^3) = (4/3)/2 = 2/3

That is, the sphere volume is ...

  sphere volume = (2/3) × (cylinder volume)

  V = (2/3)(11)

Answer:

The value of R is 0.7482.

Step-by-step explanation:

X Values

∑ = 35

Mean = 5

∑(X - Mx)2 = SSx = 68

Y Values

∑ = 34

Mean = 4.857

∑(Y - My)2 = SSy = 50.857

X and Y Combined

N = 7

∑(X - Mx)(Y - My) = 44

R Calculation

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

r = 44 / √((68)(50.857)) = 0.7482

r = 0.7482

Sorry if I get this wrong Because not for sure how you need the awnsers I dont know if this is the right way

Mx: 5.000

My: 4.857

Sum: 68.000

Sum: 50.857

sum: 44.000

X Values

∑ = 35

Mean = 5

∑(X - Mx)2 = SSx = 68

Y Values

∑ = 34

Mean = 4.857

∑(Y - My)2 = SSy = 50.857

X and Y Combined

N = 7

∑(X - Mx)(Y - My) = 44

R Calculation

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

r = 44 / √((68)(50.857)) = 0.7482

The equation (x – 5)2 = –2(y + 1) represents a parabola. Complete the statements describing the graph.

The vertex is

(5,-1)
(-5,1)
(-5,-1)

The graph opens
up
left
right
down

Answers

Answer:

(5,-1)

Step-by-step explanation:

TAKE ONE SIDE

(X-5)2=0

2X-10= 0

2X=10

X=10/2

X=5

THEN TAKE OTHE SIDE

-2(y+1) =0

-2y-2=0

-2y=2

y=2/-2

y=-1

So the answer is (5,-1)

And it should be in right down

(-5,1) , the graph opens down

What is an equation?

'An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.'

.Given equation: 2(x-5) = -2(y+1)

Evaluating left-hand side,

⇒ (x-5)2 = 0

⇒2x-10 = 0

⇒2x = 10

⇒x =10/2

⇒x = 5

Evaluating RHS,

⇒-2(y+1) = 0

⇒-2y-2 = 0

⇒-2y = 2

⇒y = 2/-2

⇒y = -1

Hence, we can conclude the vertex is at (-5,1) and the graph opens down.

t = 1.622

Step-by-step explanation:

Gives the equation, 6*e^{0.25t}=9

We are to find t

6*e^{0.25t}=9

e^{0.25t}=9/6

e^{0.25t}= 1.5

Apply ln to both Sides

ln( e^{0.25t) = ln1.5

0.25t = ln1.5

t = ln1.5/0.25

Raphael sells paintings for $200 each at a market, but has to pay $100 to reserve a table. :)

Step-by-step explanation:

The scenario that describes a proportional relationship is D; Raphael sells paintings for $200 each at a market but has to pay $100 to reserve a table.

What is directly proportional and inversely proportional relationship?

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

p = kq

where k is some constant number called constant of proportionality.

This directly proportional relationship between p and q is written as

[tex]p \propto q[/tex]where that middle sign is the sign of proportionality.

This inversely proportional relationship is denoted by;

[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]

Thus, the scenario that describes a proportional relationship is D; Raphael sells paintings for $200 each at a market but has to pay $100 to reserve a table.

Given the equation f(t) = 225(1.23)

What is the rate of growth or decay?
%
What is the initial value?

Answers

Answer:

This function doesn't make sense, unless you make it f(t)=225(1.23)^x. I will assume that you forgot to add the x squared. The rate of decay is 23%. Since the base is between 1 and 0, it is an exponential decay and you'll need to subtract the r-value with 1. (If it were an exponential growth, you would have to add 1.) The initial value or the a-value is 225.
