Find the x to the nearest tenth using this picture.
Answer:
21.1
Step-by-step explanation:
sin 49 = x / 28
0.75470958 = x/28
x = 21.1
Answer:
x=18.4
y=35
Step-by-step explanation:
So to solve for x, you're going to use one of the six trigonometric functions (you really only need to use the three main ones, sin, cos, and tan, to solve these problems). In this case you know the adjacent of the angle 49 degrees, and the hypotenuse. There is a trigonometric function which is defined as: [tex]\frac{adjacent}{hypotenuse}=cos(\theta)[/tex]. So let's plug in the known values:
[tex]cos(49) = \frac{x}{28}[/tex]
Multiply both sides by 28
[tex]cos(49) * 28 = x\\[/tex]
Calculate cos(49) using a calculator (make sure it's in degree mode):
[tex]0.656 * 28 \approx x[/tex]
[tex]18.4 \approx x[/tex]
So the second problem, you need to use the inverse of one of the trigonometric function, which essentially takes what f(x) is, and returns x. So in this case we're looking for a trigonometric function that is defined using the opposite and adjacent side, which tan is. [tex]tan(\theta)=\frac{opposite}{adajcent}[/tex]. In this case opposite=19, and adjacent=27. So plug in the known values:
[tex]tan(y)=\frac{19}{27}[/tex]
Apply the inverse of tan to both sides
[tex]y=tan^{-1}(\frac{19}{27})[/tex]
Calculate inverse of tan of 19/27 using a calculator:
[tex]y\approx35[/tex]

Given the following rectangle and circle, what appropriate value of x are the two areas equal? A: x= 3.4 B: x=5.8 C: x= 10.2 D: the curves do not intersect, so there is no solution
The correct option is D:
the curves do not intersect, so there is no solution
For what values of x are the two areas equal?
The area of the rectangle is given by:
f(x) = (x + 7)*(5x - 3)
f(x) = 5x² -3x + 35x - 21
f(x) = 5x² + 32x - 21
For the circle, the area is:
g(x) = 2*pi*(x + 6)^2
g(x) = 2pi*x^2 + 12pi*x + 72pi
The solution is given g(x) = f(x).
By graphing both functions (the green curve is the area of the rectangle, the orange one is the area of the circle). The two curves never do intercept, so the correct option is D.

The two toy store owners agree to specialize and to trade 30 puzzles for 10 puppets. The terms of trade are still 3 puzzles for each puppet. How many puzzles and puppets will each one have after they complete their trade
After completing their trade, Store Owner A has 0 puzzles and 10 puppets, and Store Owner B has 30 puzzles and 0 puppets.
Here,
Let's assume the two toy store owners are Store Owner A and Store Owner B.
Before the trade, Store Owner A has 30 puzzles and 0 puppets, and Store Owner B has 0 puzzles and 10 puppets.
They agree to trade 30 puzzles for 10 puppets at a rate of 3 puzzles for each puppet.
So, for every 3 puzzles, Store Owner A will receive 1 puppet.
Store Owner A gives away 30 puzzles and receives 30 / 3 = 10 puppets.
After the trade, Store Owner A has 0 puzzles and 10 puppets.
Store Owner B gives away 10 puppets and receives 10 * 3 = 30 puzzles.
After the trade, Store Owner B has 30 puzzles and 0 puppets.
So, after completing their trade, Store Owner A has 0 puzzles and 10 puppets, and Store Owner B has 30 puzzles and 0 puppets.

Which of the following represents a function?
Please help
Answer:
(2,3),(4,3),(-2,-3),(-4,-3)
Step-by-step explanation:
A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).
This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.
The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.
A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.
In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:
(5,1),(5,2),(5,3),(5,4)
Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.
The value of n from the set {6, 7, 8, 9} that holds true for 4n − 12 < 2n + 2 is?
The value of n that satisfies the inequality is 6.
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
4n − 12 < 2n + 2
For n= 6

2(6) + 2 = 14
Thus, n=6 satisfies
For n= 7

2(7) + 2 = 16
Thus, n=7 not satisfies
For n=8
4(8) - 12 = 20

It is given that alyssa's favorite tennis team has 8 players on them. She has taken a picture with every single athlete individually and wants to post some of the pictures on her wall. But she only wants to post 3 pictures on her wall.
For this we hve to use factorials. In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. The factorial of n also equals the product of n with the next smaller factorial: For example, The value of 0! is 1, according to the convention for an empty product.
So it will be - [tex]\frac{8!}{3!(8-3)!}[/tex] as this is the formula for combination
