Answer: Choice D.  sqrt(30)

sqrt is shorthand for "square root"

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

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.

11 * 2 = 22

14 + 22 = 36

Answer: 36

Step-by-step explanation: Perimeter is the outside of a shape, so you double each number and add them since a parallelogram has 4 sides. 11+11=22. 7+7=14. 14+22=36

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.

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.

[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:

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:

897.23

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:

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).

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.

-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.
