Х
o 7.73 cm
8.12 cm
16.5 cm
23.78 cm
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).

write the equation of the line perpendicular to y=1/5x-11 passing through the point (0,-8)
Step-by-step explanation:
the slope of a line function is always the factor of x.
in our case here : 1/5
it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
in our case that means y increases by 1 for every increase of x by 5.
now, the perpendicular slope simply changes x and y upside-down and flips the sign.
so, here the perpendicular slope is : -5/1 = -5
the line function looks therefore like
y = -5x + b
b is the y-intercept, and we get it by using the coordinates of the point for x and y :
-8 = -5×0 + b = b
so, the full line function is
y = -5x - 8

By the Power of Power rule,
(167) * = 16
So, 16ż must equal
in radical form.
Answer:
16√16Step-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).

Natalia is joining an online music service that charges a monthly membership fee of $5.95. A tax of 9% is applied to the monthly membership fee, and an additional one-time initiation fee of $15 is charged at the beginning of the membership. Which of the following represents Natalia’s total charge, in dollars, for a membership lasting m months?
A) 1.09(5.95m + 15)
B) 1.09(5.95m) + 15
C) 1.09m(5.95 + 15)
D) 0.09m(5.95) + 15
P.S. please provide the answer with the working
Awnser:
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
How to form mathematical expression from the given description?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.
How to find the percentage from the total value?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:
Monthly membership fee by online music service considered = $5.95Tax of 9% on monthly feeOne time initiation fee = $15Time for which she uses this service = m monthsTotal 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

Determine a series of transformations that would map Figure P onto Figure Q.
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.

What is the area of a right triangle with a base of 4 feet and a height of 8 feet?
Answer:
16 feet squared
Step-by-step explanation:
We'll use the formula for finding the area of a triangle:
area = [tex]\frac{1}{2}[/tex] of the base times the height
First, we'll find [tex]\frac{1}{2}[/tex] of the base. Our base is 4 feet, and half of 4 feet is 2 feet. Now, we have to multiply that by the height. The height is 8 feet, so we have to multiply 8 feet by 2 feet. 8 times 2 is 16, and feet times feet gives us feet squared. So we have 16 feet squared as our final answer.
Hopefully that was helpful! Let me know if you have any more questions.
