I’m tryna look for that too

The value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].

Given:

The function [tex]f[/tex] has an inverse and [tex]f(-3)=6[/tex].

To find:

The value of [tex]f^{-1}(6)[/tex].

Explanation:

If a point [tex](a,b)[/tex] lies on the function [tex]f(x)[/tex], then the point [tex](b,a)[/tex] must lies on the inverse function [tex]f^{-1}(x)[/tex].

According to the given value [tex]f(-3)=6[/tex], the point [tex](-3,6)[/tex] lies on the function [tex]f(x)[/tex]. So, the point [tex](6,-3)[/tex] must be lies on [tex]f^{-1}(x)[/tex].

[tex]f^{-1}(6)=-3[/tex]

Therefore, the value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].

Answer:

part 1:

see in the picture, E is the centre of the kite

1) AC = 2.EC = 40

2) CD = sqrt( ED² + EC² ) = sqrt(21² + 20²) = 29

3) ABE = 90⁰ - 51⁰ = 39⁰

4) BCE = BAE = 51⁰

part 2:

we have:

3x + 7 = (3x - 1 + 8x)/ 2

<=> 3x + 7 = 5.5x - 0.5

<=> 2.5x = 7.5

<=> x = 3

5) with x = 3 => UV = 3.3 - 1 = 9 - 1 = 8

6) XY = 3.3 + 7 = 9 + 7 = 16

7) TW = 8.3 = 24

9) the width of the base is x (x > 0)

we have:

28.5 = (x + 25)/2

<=> x + 25 = 57

<=> x = 32

The cellular connection buys new model Z-phones for $80 each and sells them for $200. What is the percent markup, n, for the model z-phone?

Answers

Answer:

250%

Step-by-step explanation:

Hi there!

In order to solve this problem, we have to divide 200 by 80.

When we do this, we get 2.5. The number in the ones spot, in this case 2, would be worth 200%.

Now we have the 0.5

A half is equivalent to 50%, so we add those two percentages together to get 250%.

Step-by-step explanation:

18

1 to 4, 5 to 20

Yes, this is correct

WE can multiply 1*5 and 4*5 to get 5 to 20

19

Wrong

3 to 11, 1 to 3 isn't correct

For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)

So, no

20

2/3 is 2 to 3

14/21 is 14 to 21

If we multiply 2*7 and 3*7, we get 14 to 21

21 25 to 30 is  equal to 35 to 42

They just added 7 to both numbers

if we divide ratio 1 by 5, we get 5:6

if we divide ratio 2 by 7 we get 5 to 6

18. Yes
19. No
20. Yes
21. I think so
