Answer:

[tex]1.357*10^4[/tex]

Step-by-step explanation:

A star is 2.3 x 10^2 light years away

We know that one light year is about 5.9 x 10^12 miles away

So, we know the star is 2.3 x 10 ^2 x 5.9 x 10^12 = 13.57 x 10^14 = 1.357 x 10^14

Hope this helps :)

Find the 107 the derivative of the function

Answers

Answer:

Step-by-step explanation:

Pattern

dx/dy = - sin(x)

d^2/dx^2 = -cos(x)

d3/dx^3 = sin(x)

d4/dx^4 = cos(x)

So if you divide 107 by 4 what's the remainder?

107 / 4 = 26 with a remainder of 3

So the answer is going to be the third one down or d107/dy^107 = sin(x)

The circumference of the base of a cone is 10π cm. The circumference of the base of a second similar cone is 20π cm. What is the ratio of the surface area of the first cone to that of the second cone?

Answers

Given:

The circumference of the base of a cone is 10π cm.

The circumference of the base of a second similar cone is 20π.

To find:

The ratio of the surface area of the first cone to that of the second cone.

Solution:

Let the radii of base of two cones are [tex]r_1[/tex] and [tex]r_2[/tex] respectively.

Circumference of the circular base is [tex]2\pi r[/tex], where, r is radius.

We have,

[tex]2\pi r_1=10\pi\text{ cm}[/tex]

[tex]r_1=\dfrac{10\pi}{2\pi}\text{ cm}[/tex]

[tex]r_1=5\text{ cm}[/tex]

And,

[tex]2\pi r_2=20\pi\text{ cm}[/tex]

[tex]r_2=\dfrac{20\pi}{2\pi}\text{ cm}[/tex]

[tex]r_2=10\text{ cm}[/tex]

It two cons are similar, then ratio of there areas is equal to square of the ratio of there corresponding dimensions, i.e., radius or heights.

[tex]\dfrac{A_1}{A_2}=\left(\dfrac{r_1}{r_2}\right)^2[/tex]

[tex]\dfrac{A_1}{A_2}=\left(\dfrac{5}{10}\right)^2[/tex]

[tex]\dfrac{A_1}{A_2}=\left(\dfrac{1}{2}\right)^2[/tex]

[tex]\dfrac{A_1}{A_2}=\dfrac{1}{4}[/tex]

The ratio form is

[tex]V_1:V_2=1:4[/tex]

Therefore, the ratio of the surface area of the first cone to that of the second cone is 1:4.

The ratio of the surface area of first cone to that of the second cone is; 1:4

Surface Area

Formula for the circumference of the base of a cone is;

C = 2πr

Where;

C is circumference

r is radius

Thus;

For the first cone;

10π = 2πr

r = 10π/2π

r = 5

For the second cone;

20π = 2πr

r = 20π/π

r = 10

Now, formula for surface area of the base is;

A = πr²

Thus, ratio of both area of first cone to second cone is;

A1/A2 = 5²/10²

A1/A2 = 25/100

A1/A2 = 1/4

Thus, ratio of first cone to that of the second cone is; 1:4

Answers

Answer:

x = 1,

Common Difference = -3

Step-by-step explanation:

Each number in series has the same difference, hence

(x + 1) - (2x+3) = (2x + 3) - (x + 7) Solve to find => x = 1Plug in value of x into (x+1) - (2x+3)

Which solves for -3

Complete Question:

An object dropped from rest from the top of a tall building on Planet X falls a distance d(t)=13t^2 feet in the first t seconds. Find the average rate of change of distance with respect to time as t changes from t1=2 to t2=10. This rate is known as the average velocity, or speed.

The average velocity as t changes from 2 to 10 seconds is _______ feet/sec?

Answer:

[tex]v = 156[/tex]

Step-by-step explanation:

Given

[tex]d(t)=13t^2[/tex]

Time Interval: (a,b)

[tex]a = 2[/tex]

[tex]b = 10[/tex]

Required

Determine the average rate of change (v)

This is calculated as thus:

[tex]v = \frac{d(b) - d(a)}{b - a}[/tex]

Substitute values for b and a

[tex]v = \frac{d(10) - d(2)}{10 - 2}[/tex]

[tex]v = \frac{d(10) - d(2)}{8}[/tex]

Calculate d(10): Substitute 10 for t

[tex]d(t)=13t^2[/tex]

[tex]d(10) = 13 * 10^2[/tex]

[tex]d(10) = 13 * 100[/tex]

[tex]d(10) = 1300[/tex]

Calculate d(2): Substitute 2 for t

[tex]d(t)=13t^2[/tex]

[tex]d(2) = 13 * 2^2[/tex]

[tex]d(2) = 13 * 4[/tex]

[tex]d(2) = 52[/tex]

The equation [tex]v = \frac{d(10) - d(2)}{8}[/tex] becomes

[tex]v = \frac{1300 - 52}{8}[/tex]

[tex]v = \frac{1248}{8}[/tex]

[tex]v = 156[/tex]

Hence, the average rate of change is 156ft/s

Answers

Answer:

B. 2:1, for every two yellow fish there is one orange fish

Step-by-step explanation:

So you have 6 yellow fish and 3 orange fish.

You can divide both these values by 3 to get:

2 yellow fish: 1 orange fish

Therefore, the simplified version of the ratio is 2:1

In context this means for every 2 yellow fish there is 1 orange fish.

The answer is then B.
