The speed of light is approximately 299,000,000 meters per second.

What is the speed of the light, in meters per second, using scientific notation?

The radius of the base of the vase in cm is 8.26 cm

P = F / A

700 = 15 / A

Cross multiply

700 × A = 15

Divide both sides by 700

A = 15 / 700

Multiply by 10000 to express in cm²

A = (15 / 700) × 10000

A = 214.29 cm²

A = πr²

Divide both side by π

r² = A / π

Take the square root of both sides

r = √(A / π)

r = √(214.29 / 3.14)

r = 8.26 cm

Answer:

Step-by-step explanation:

Domain is the set of all inputs for which the given function is defined.

graphically it represents the shadow of the graph taken on the x axis from above and below the x axis

Here is the shadow will be formed from -3 till +∞, hence we have our domain  as [-3 , ∞ ]

(a) The differential equation

[tex]y' + \dfrac14 y = 3 + 2 \cos(2x)[/tex]

is linear, so we can use the integrating factor method. We have I.F.

[tex]\mu = \displaystyle \exp\left(\int \frac{dx}4\right) = e^{x/4}[/tex]

so that multiplying both sides by [tex]\mu[/tex] gives

[tex]e^{x/4} y' + \dfrac14 e^{x/4} y = 3e^{x/4} + 2 e^{x/4} \cos(2x)[/tex]

[tex]\left(e^{x/4} y\right)' = 3e^{x/4} + 2 e^{x/4} \cos(2x)[/tex]

Integrate both sides. (Integrate by parts twice on the right side; I'll omit the details.)

[tex]e^{x/4} y = 12 e^{x/4} + \dfrac8{65} e^{x/4} (8\sin(2x) + \cos(2x)) + C[/tex]

Solve for [tex]y[/tex].

[tex]y = 12 + \dfrac8{65} (\sin(2x) + \cos(2x)) + Ce^{-x/4}[/tex]

Given that [tex]y(0)=0[/tex], we find

[tex]0 = 12 + \dfrac8{65} (\sin(0) + \cos(0)) + Ce^0 \implies C = -\dfrac{788}{65}[/tex]

and the particular solution to the initial value problem is

[tex]\boxed{y = 12 + \dfrac8{65} (\sin(2x) + \cos(2x)) - \dfrac{788}{65} e^{-x/4}}[/tex]

As [tex]x[/tex] gets large, the exponential term will converge to 0. We have

[tex]\sin(2x) + \cos(2x) = \sqrt2 \sin\left(2x + \dfrac\pi4\right)[/tex]

which means the trigonometric terms will oscillate between [tex]\pm\sqrt2[/tex]. So overall, the solution will oscillate between [tex]12\pm\sqrt2[/tex] for large [tex]x[/tex].

(b) We want the smallest [tex]x[/tex] such that [tex]y=12[/tex], i.e.

[tex]0 = \dfrac8{65} (\sin(2x) + \cos(2x)) - \dfrac{788}{65} e^{-x/4}[/tex]

[tex]\dfrac{788}{65} e^{-x/4} = \dfrac{8\sqrt2}{65} \sin\left(2x + \dfrac\pi4\right)[/tex]

[tex]\dfrac{197}{\sqrt2} e^{-x/4} = \sin\left(2x + \dfrac\pi4\right)[/tex]

Using a calculator, the smallest solution seems to be around [tex]\boxed{x\approx21.909}[/tex]

The relations from the following sets of ordered pairs which is a function is; {(8,1),(−4,1),(3,5),(0,4),(−1,2)}

It follows from the definition of a function that a function from an array of X-values to a set Y-values assigns only one Y-value to each X-value.

Answer:

3800grams

Step-by-step explanation:

multiply by 1000

Answer: Choice A) It has a range of 17

Reason:

The smallest value is 8 and the largest is 14. The range is the distance between these min and max

range = max - min = 14 - 8 = 6

So the range is 6 instead of 17.

The range of a data set is the difference between maximum and minimum thus the range of the given data set 8, 10, 10, 12, 12, 12, 12, 14, 14,16 is 8 so option (A) does not describe the data set.

Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.

For example;

Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.

As per the given data set.

8, 10, 10, 12, 12, 12, 12, 14, 14,16

The range = maximum - minimum

Range = 16 - 8 = 8

The median of the data set is 12.

The mode is the highest frequency thus 12 is the mode of the data set.

Hence "The range of a data set is the difference between maximum and minimum thus the range of the given data set 8, 10, 10, 12, 12, 12, 12, 14, 14,16 is 8".

Step-by-step explanation:

20 gallons of gas was consumed by the car that has efficiency of 20 miles per gallon  and 30 gallons of gas was consumed by the car that has  efficiency of 30 miles per gallon .

The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 30 miles per gallon of gas.

Therefore,

let

x = number of gallons for car that consume 20 miles per gallon of gas

y = number of gallons for car that consume  30 miles per gallon of gas

Hence,

x + y = 50

20x + 30y = 1300

20x + 20y = 1000

20x + 30y = 1300

10y = 300

y = 300 / 10

y = 30

Therefore,

x = 50 - 30

Using a system of equations, it is found that the lengths of the sides of the triangle are given as follows:

5.29 feet, 2.43 feet, 5.79 feet.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are the lengths, that are x, y and z.

The length of one side of a triangle is 2 feet less than three times the length of its second side, hence:

x = 3y - 2.

The length of the third side is 3/4 of the sun of the lengths of the first two sides, hence:

z = 0.75(x + y).

Find the lengths of all three sides if the perimeter of the triangle is 17.5 feet, hence:

x + y + z = 17.5.

3y + 2 + y + 0.75(3y - 2 + y) = 17.5

4y + 0.75(4y - 2) = 15.5.

Answer:

P(w) = 3w+4

Step-by-step explanation:

For a Linear Equation , it takes the Form y = mx + c

where c is the Constant which is y-value at x=0

and the m is the Slope which is the change in y-value for a 1-unit change in x-value

So for our Question

y-value is represented by P(w) , Number of Rats

x-value is represented by w , Number of Weeks

So the Constant (c) is the P(w) at w=0 which is 4

and the Slope is the Change in P(w) value as w changes by 1 unit , which from week 0 to week 1 , P(w) changed from 4 to 7 , so the Change =7-4=3

Then the Slope m = 3

So the Linear Equation will be P = mw+c

Then P(w) = 3w+4

Answer:

Step-by-step explanation:

As the length AB increases, the measure of C increases

As the length AB increases, the measure of C increases.

An angle is formed when two lines or rays meet at a single point. The common point is referred to as the vertex. The length of the angle formed when two rays or arms intersect at a common vertex is known as an angle measure in geometry.

Angles and sides in relation to one another:

The biggest side and angle of any triangle are in opposition to one another.

The smallest side and angle in every triangle are on opposing sides.

The middle side and middle angle are always in opposition to one another in triangles.

When we extend vertex A further to the left of vertex B,

we increase the side length of AB.

As the length AB increases, the measure of opposite angle increases.

Let C be the angle opposite to AB.

Therefore, as the length AB increases, the measure of C increases.

Answer:

  35

Step-by-step explanation:

The equations will be "consistent" when they describe lines that are not parallel.

The slope of a line whose equation is written in this form is the opposite of the ratio of the y-coefficient to the x-coefficient:

  line 1 slope = -8/20 = -2/5

  line 2 slope = -14/35 = -2/5

These lines have the same slope, so will be parallel unless they have the same y-intercept.

The y-intercept of each line is the ratio of the constant to the y-coefficient:

  line 1 y-intercept = 20/20 = 1

  line 2 y-intercept = k/35

We want these lines to have the same y-intercept so that they are not inconsistent. This requires ...

  k/35 = 1

  k = 35

For the equations to be consistent, we must have k = 35.

Additional comment

Linear equations are generally categorized as "consistent" or "inconsistent," and "dependent" or "independent."

Equations are "inconsistent" if there are no values of the variables that satisfy all of the equations. They are "dependent" if they describe exactly the same relation between the variables. "Consistent" equations may be "dependent" (describing the same line, as here), or "independent" (describing lines with different slopes.)
