-3 → -1 → 1 → 3 → 5 → 7 → 9 → etc

+2 +2 +2 +2 +2 +2

By using function :

U1 = -3

U2 = -1

b = -1 - (-3)

b = -1 + 3

b = 2

Un = a + (n - 1)b

Un = -3 + (n - 1)2

Un = -3 + 2n - 2

Un = 2n - 5

Find U6!!

U6 = 2(6) - 5

U6 = 12 - 5

U6 = 7

Answer: Rotate 280 degrees

Step-by-step explanation:

Each 90 degree rotation makes the figure go into the next quadrant of the graph. So, going clockwise, you have to move the figure three quadrants to get Figure P to the position of Figure Q. Thus, 3 x 90 = 280 degrees. There is only one transformation required.

Step-by-step explanation:

Ellis is going on a tour that costs $68 while on vacation. He brought less than $96 to pay for the cost of the tour and dinner.

$68 + d less than $96

$68 + d < $96

Note:

The value of x is 23.78 cm and this can be determined by using the cosine function which is an important trigonometric function.

Given :

A right triangle. The hypotenuse is labeled as 25 centimeters. The base is labeled as x.

Using the trigonometric functions the value of x can be determined. The cosine function can be used in order to determine the value of 'x'.

The cosine function is the ratio of the base to the hypotenuse. It is given by:

[tex]\rm cos\theta=\dfrac{Base}{Hypotenuse}[/tex]

Now, put the values of the base, hypotenuse, and the angle [tex]\theta[/tex] in the above equation.

[tex]\rm cos 18^\circ = \dfrac{x}{25}[/tex]

[tex]\rm x = cos18^\circ \times 25[/tex]

x = 23.78 cm

So, the correct option is D).

Answer:

Step-by-step explanation:

The idea of the square root of a number is that the square of it gives the number. Then the square of the square root of 16 will give 16.

The middle line of your problem statement tells you that the square of 16^(1/2) gives 16. This lets you interpret the meaning of 16^(1/2) as the same thing as the square root of 16.

  16^(1/2) = √16 . . . . in radical form

_____

Additional comment

The index of the radical can be seen to be the denominator of the corresponding rational exponent. Of course, the index 2 in a square root symbol is "understood", rather than shown explicitly.

Using similar logic, for example, we can write ∛8 = 8^(1/3).

Natalie Spent $59.54 on songs after 5 months at online music service.

Step-by-step explanation:

Given:

Total membership cost =$14.99

Number of songs purchased in each month = 9

Cost per song = $0.99

We need to find total amount she had spent after 5 months.

Solution:-

So First we will Number of songs purchased in 5 months.

1 month = 9 songs

So in 5 months = Songs purchased in 5 months.

By Using Unitary method we get;

Songs purchased in 5 months =

Now Also Given:

1 song = $0.99

45 songs = Cost for 45 songs.

Again by using Unitary method we get;

Cost for 45 songs =

No Total Amount Natalie spent after 5 months is equal to Total membership cost plus Cost of songs purchased in 5 months.

framing in equation form we get;

Total Amount Natalie spent =

Hence Natalie Spent $59.54 on songs after 5 months at online music service.

The expression representing Natalia’s total charge, in dollars, for a membership lasting m months is given by: Option B: 1.09(5.95m) + 15

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given that:

Total charge Natalia has to pay for m months = Monthly membership fees for m months + 9% tax on it per month + one time initiation fees.

Monthly membership fees + tax amount = $5.95 + 9% of $5.95

= [tex]5.95 + \dfrac{5.95}{100} \times 9 = 5.95 (1 + 0.09) = 5.95(1.09)[/tex] (in dollars)

This is paid for 'm' months, so:

Membership fees + tax amount (for m months) = [tex]5.95 \times (1.09)\times m[/tex] (in dollars)

And as One time initiation fee = $15, thus, we get:

Total charge Natalia has to pay for m months = [tex]5.95 \times (1.09)\times m + 15[/tex]

Equivalently, this is 1.09(5.95m) + 15 (in dollars) (as given by Option B)

(We don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)

Thus, the expression representing Natalia’s total charge, in dollars, for a membership lasting m months is given by: Option B: 1.09(5.95m) + 15
