Answer:

The formula to find the voltage is:

[tex]v=\sqrt{P*R}[/tex]

And the voltage is 4 volts

Step-by-step explanation:

To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?

First, multiply both sides with R:

[tex]P*R=\frac{v^{2} }{R} *R[/tex]

That would result into removing the divisor R from the right side of the equation:

[tex]P*R=v^{2}[/tex]

Next, square-root both sides:

[tex]\sqrt{P*R} =\sqrt{v^{2} }[/tex]

That would result in removing the square of v from the right side of the equation:

[tex]\sqrt{P*R} =v[/tex]

Thus we get the equation, [tex]v=\sqrt{P*R}[/tex].

To find out the voltage, simply replace R with 32 and P with 0.5

[tex]v=\sqrt{0.5*32}[/tex]

[tex]r=\sqrt{16}[/tex]

[tex]r=4[/tex]

Thus, the voltage is 4 volts.

Answer:

-16

Step-by-step explanation:

x+6=x/2-2

solve the equation, x=-16

check:

-16+6=-10

-16/2=-8

-10-(-8)=-2

If the sum of a number and six is two less than half the same number then the number is -16.

Given,

The sum of a number and six is two less than half the same number

We will find the unknown number.

We have,

The sum of a number and six is two less than half the same number.

Let the unknown number be M.

Let us separate the given statement into parts:

- Sum of a number and six

This can be written as M + 6.

- is means equal sign "=".

- Two less than half the same number.

This can be written as (1/2)M - 2.

Now,

We can write as:

M + 6 = (1/2)M - 2

M - (1/2)M = -2 - 6

(1/2)M = -8

M = -8 x 2

M = -16

Thus the unknown number is -16.

We can also crosscheck:

M + 6 = (1/2)M - 2

-16 + 6 = (1/2)(-16) - 2

-10 = -8 -2

-10 = -10

Hence proved.

Answer:Three is the right answer I just finished

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

What you wrote, x + 8/x - 3 means [tex] x + \dfrac{8}{x} - 3 [/tex].

I assume you didn't mean that, but instead, you mean

[tex] \dfrac{x + 8}{x - 3} [/tex], so I'll use this expression in the problem.

A fraction cannot have zero in the denominator since division by zero is undefined and not allowed. The denominator of the fraction is x - 3.

We need to find which value of x makes the expression x - 3 have a value of zero. Then that is the value of x that must be excluded from the domain.

We set the denominator equal to zero, and we solve for x.

x - 3 = 0

Add 3 to both sides.

x = 3

A value of 3 used for x makes the denominator equal zero, so the real number for which the expression is undefined is

x = 3.

It can be deduced from part a that the final result will be twice the original number 'n'

The number 'n' multiplied by 4 = (4 * n) = 4n

10 added to 4n = 4n + 10

The result of the sum divide by 2 = (4n + 10) / 2

Answer:

hi :)

Step-by-step explanation:

Answer:

x- intercept at (3, 0)

y- intercept at (0, 2)

Step-by-step explanation:

x-intercept occurs at y=0.

4x +6y= 12

when y=0,

4x +6(0)= 12

4x= 12

x= 12 ÷4

x= 3

Thus, x-intercept occurs at x=3, at the point (3, 0).

y- intercept occurs at x=0.

4x +6y= 12

when x=0,

4(0) +6y= 12

6y= 12

y= 12 ÷6

y= 2

Thus, y- intercept occurs at the point (0, 2).

1. The first option is represented by a linear function, ∴ y = 50x + 150. The y intercept here is 150, as the first week is 200 dollars, not the 0th week. 200 - 50 = 150.

Given the domain here is 1 - 6 (6 weeks) we can plug in x as 1,2,3 etc and solve for y, completing the table.

Option A :

Week | 1 | 2 | 3 | 4 | 5 | 6 |

Amount Paid | 200 | 250 | 300 | 350 | 400 | 450 |

And for option b we have an exponential function. 1 + 10% = 1 + 0.1 = 1.1. Therefore we have the function ∴ y = 200( 1.1 )^x-1 that models this situation.  Remember that we have " x - 1 " as the exponent rather than x, as the first week begins with 200 dollars, not the 0th week.

That gives us the following table,

Option B :

Week | 1 | 2 | 3 | 4 | 5 | 6 |

Amount Paid | 200 | 220 | 242 | 266.2 | 292.82 | 322.102 |

2. (a) We already calculated the " iterative rules " for each sequence in the first part. For your explanation on that behalf, just include the explanation above. Rule of Option A : y = 50x + 150. Rule of Option B : [tex]y = 200( 1.1 )^{x-1}[/tex].

(b) Let's take an example week and substitute into our equations to help clarify our friend's doubt. Say week 2...

y = 50(2) + 150 = 100 + 150 = 250 ✓

y = 200( 1.1 )^2-1 = 200( 1.1 )^1 = 200( 1.1 ) = 220 ✓

3. (a) A function is an equation that represents the relation between x and y, which is exactly the purpose of the rules y = 50x + 150, and y = 200( 1.1 )^x-1.

(b) I disagree with my friend. These particular examples do have y - intercepts, but just because a rule is a function, doesn't make it have a y - intercept. There are some exceptions, such as y = 1 / x.

(c) An input such as 18.5 is meaningless, as x represents the weeks. An employer doesn't provide the payments at half weeks.

4. Let's substitute 20 as x,

y = 50 * 20 + 150 = 1,000 + 150 = $1,150

y = 200( 1.1 )^x-1 = 200( 1.1 )^20-1 = 200( 1.1 )^19 = $1,223.1818

The first payment option will provide the greatest total income.

Answer:

897.23

Step-by-step explanation:

The decimal places start at the tenths:

00.tenths, hundredths, thousandths

So you would need to end up with only two numbers after the decimal.

To round, if a number is 4 or less, leave the next number as it is.

Ex: 2.32 → 2.3                    Rounding to the tenths

     78.614 → 78.6               Rounding to the tenths

If the number is 5 or higher, round up one number

EX: 37.76 → 37.8                Rounding to the tenths

      6.389 → 6.4                 Rounding to the tenths

Our number, 897.234, needs to be rounded to the hundredths place, so use the number to its right to determine the rounded value. The number 4 means that the hundredths place will remain the same, so the new value is:

======================================================

Explanation:

We'll use the intersecting chords theorem here

We multiply the pieces of each chord together and set the products equal to one another to help solve for x

TW*WU = CW*WV

x*2x = 6*10

2x^2 = 60

x^2 = 60/2

x^2 = 30

x = sqrt(30)

The value of x is √30. The correct option is D.

The measure of the angle created when two chords collide inside a circle is one-half the sum of the arcs intercepted by the angle and its vertical angle.

Use the intersecting chords theorem here. Multiply the pieces of each chord together and set the products equal to one another to help solve for x

TW*WU = CW*WV

x*2x = 6*10

2x² = 60

x² = 60/2

x² = 30

x = √(30)

Therefore, the value of x is √30. The correct option is D.

Answer:

Let's call x as the number of friends, now, in Theatre A we have:

Price for x tickets = x*$14.50

price for 3 tubs of popcorn = 3*$5.75 = $17.25

Total price:

Pa(x) = $14.50*x + $17.25

Now, for Theatre B we have:

Price for x tickets = $13*x.

Price for 3 tubs of popcorn: = 3*$6.75 = $20.25

Total price:

Pb(x) = $13*x + $20.25.

Now, we can find the number of friends x in such case that they will pay the same in each theater by:

Pa(x) = Pb(x)

$14.50*x + $17.25 = $13*x + $20.25.

Now we solve this for x:

($14.50 - $13)*x = $20.25 - $17.25 = $3

$1.50*x = $3

x = $3/$1.50 = 2.

Then, if there are 2 friends, they will pay the same in both theatres

If there are more tha 2 friends, the cheaper place will be Theatre B, because the slope is smaller, which means that for each additional ticket the total price will increase less.

Ok so there are two ways to do this kind of pre-algebra.

I'm going to do it the way I learned it, and the way they teach you in schools.

Ok so you want the variables on one side and the constant term (normal numbers) on the other side (of the equation).

So to do that you have to bring the 6 to the right side.

17h=40+6

Except when you move it to the other side you have to change the sign in front of it.

+ → -

- → +

× → ÷

÷ → ×

In this case, there is an addition sign in front of the 6.

So + → - and the final equation is...

17h=40-6

If you want to do it the way they do it in schools, then you have to remove 6 from both sides (so it will still be equal).

17h+6=40

You have to subtract 6 from (17h+6), which would be 17h.

Then you have to subtract 6 from (40), which would be 40+(-6) or 40-6

The final equation is 17h=40-6

Ok so 40-6=34.

So 17h=34

Divide 34 by 17 or divide each side by 17.

h=34/17 or 2

Step-by-step explanation:

Given that:

[tex]\angle 5[/tex] is a supplement of [tex]\angle 6[/tex].

m[tex]\angle 5[/tex] = 78°

To find:

m[tex]\angle 6[/tex] = ?

Solution:

First of all, let us learn about the concept of an angle being a supplement of the other angle.

[tex]\angle B[/tex] is known as supplement of [tex]\angle A[/tex], if sum of the two angles is equal to 180°.

[tex]i.e. \angle A +\angle B=180^\circ[/tex].

For example, angle made on one side by a line intersecting the other line are supplement of each other.

Here, we are given that [tex]\angle 5[/tex] is a supplement of [tex]\angle 6[/tex].

In other words:

[tex]\angle 5+\angle 6=180^\circ[/tex]

Putting value of [tex]\angle 5[/tex]:

[tex]\Rightarrow 78^\circ+\angle 6=180^\circ\\\Rightarrow \angle 6 =180^\circ-78^\circ\\\Rightarrow \bold{\angle 6 =102^\circ\\}[/tex]

So, the answer is: [tex]102^\circ[/tex]

Answer:

Subtract 9 from each side of the equation.

m = – 11

Step-by-step explanation:

m + 9 = – 2

To solve the above equation, we simply subtract 9 from each side of the equation.

This is illustrated below:

m + 9 = – 2

Subtract 9 from each side of the equation

m + 9 – 9 = – 2 – 9

m + 0 = – 11

m = – 11

Therefore, the value of m is – 11
