PLS HELP
Which of the following is a Pythagorean triple?
A. (3, 4, 6)
B. (6, 8, 10)
C. (10, 12, 15)
D. (5,5, 10)

Answer:

f to the power of -1(x) =2*10to the power of x

f-1(x) =2*10x

Step-by-step explanation:

MAKE SURE THE -1 IS TO THE POWER OF F!!!! I DONT KNOW HOW TO TYPE IT ON COMPUTER THAT WAY. SAME THING GOES FOR X AFTER 10, MAKE SURE X IS TO THE POWER OF 10

inside the parenthesis you go the opposite way of the sign so |x+7| shifts it to the left 7 units

Answer:

20k

Step-by-step explanation:

if he can run 10k in 30 minutes, and 30 minutes is 1/2 of an hour, then you can say that he can run 10k(2) or 20k in an hour.

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

Answer:

A. 2, 84, 40

Step-by-step explanation:

x/3 = 8/12

x = 3*8/12 =24/12 = 2

56/y = 8/12

y = 56*12/8 = 7*12 = 84

8/12 = z/ 60

z = 8*60/12 = 40

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:

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

its right and can I please have brainlist

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

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

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.

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 )
