Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.
Answer:
[tex]\frac{13}{\sqrt{2}}[/tex] or 9.19 (approximately). I am confused how the question is asking for it to be typed, so it might be this: [tex]\frac{13}{\sqrt{2}}[/tex] , but if you cannot type that in, then maybe it is sin(45) * 13.
Step-by-step explanation:
The three main trigonometric ratios are: sine (o/a), cosine (a/h), or tangent (o/a) depending on the given. To help you remember them, you can use the saying SOH CAH TOA, which is sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/adjacent.
In this problem, we are going to use one that has the hypotenuse, which rules out tangent, and leaves us with sine or cosine. Since, we are given the hypotenuse and the opposite side (from angle 45), we will be using sine. Then we just need to set up the trigonometric ratio:
sin (45) = x/13
Then, you need to get x by itself, so you multiply 13 on each side, which leaves you with:
x = sin(45) * 13 = 9.19 (approximately)
This could also be seen as a special right triangle, where the hypotenuse is [tex]x\sqrt{2}[/tex], and the two sides are x.
So, to find the value of x, you could also do this: 13/[tex]\sqrt{2}[/tex], which might be how the question wants it formatted.
Good luck!

Answer: 45 = 5t
Step-by-step explanation:
From the question, Jamahl wants to celebrate his birthday by roller skating with his friends and he has a total of $45dollar to buy t tickets.
We are further told that the ticket costs $5. The equation that matches the situation will be:
45 = (5 × t)
45 = 5t
t = 45/5
t = 9
He can buy 9 tickets
Find the vertex of the quadratic equation f(x) = x2 - 4x - 10
Answer:
2
Step-by-step explanation:
Answer:
vertex = (2, - 14 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² - 4x - 10
Using the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² - 4x
f(x) = x² + 2(- 2)x + 4 - 4 - 10
= (x - 2)² - 14 ← in vertex form
with vertex (h, k ) = (2, - 14 )

Ms.Keller is racing bob to see who can read the book faster. the book has 342 pages ms. Keller has already completed 300 pages. If she reads 2 pages per min how mint min will it take her to Finnish the book
Answer:
21 minutes
Step-by-step explanation:
Ms.Keller is speed reading a book that has 342 pages, she has already completed 300 of them and can read 2 pages per minute. The question is asking how long it'll take her to finish this book.
So we know the vital information that Keller reads two pages per minute and she only has 42 pages left of the book, this is all we need to answer the question.
All we need to do is divide 42 by 2 :
42 / 2
21
Therefore, it'll take Ms.Keller 21 minutes to finish the book at the constant speed

Find the total surface area of the net below.
Answer:
122
Step-by-step explanation:
The total surface area is 122. This is because 7 times 4 equals 28. Then you do 7 times 5 twice, which makes 35 times 2, which makes 70. This is because there are 2 triangles with 7 as the base and 5 as the height. Next, you do 4 times 3 twice, which equals 12 + 12 which adds up to 24. Now add the numbers up. 70 + 28 + 24, which = 122.

Is the following relation a function? {(1, 2), (4, -3), (4, 7), (8, -6)}
a. Yes
b. No
help plsss
Answer:
A function will not have any repeating x values...it can have repeating y values, just not the x ones. So all ur x's have to be different.
This relation is NOT a function because u have repeating x values...u have 2 x values that are 0.3

Jane is making wind seashells. She need 12 sea shells for the big one and 8 for the small one. How many wind chimes of the same number would she make form 100 sea shells?
Answer: See explanation
Step-by-step explanation:
Let the wind chimes of the same number that would make her form 100 sea shells be represented by x.
From the information given in the question, this can be denoted as:
12x + 8x = 100
20x = 100
x = 100/20
x = 5
She'll need 5 wind chimes. Let's check
12x + 8x
12(5) + 8(5)
60 + 40 = 100
