HELP ME PLEASE THIS IS DUE TODAY

Mathematics

Because measure 4 and 2 are vertical angle, they are congruent, which mean measure 2 is 77. Measure 2 and 3 are complementary, meaning they equal 180, so 3 would be 103 because 180-77=103. Masure 1 is 103 also

If an arithmetic sequence has a4 = 107 and a8 = 191, what is a₁?<br>PLEASE HELP ME​
katen-ka-za [31]

\text{nth term of  an arithmetic sequence,}\\\\a_n = a_1 + (n-1)d\\\\a_4 = a_1 +3d=107~~~......(i)\\ \\a_8=a_1+7d = 191~~~......(ii)\\\\\\\text{(ii) -(i):}\\\\~~~~~~a_1+7d-a_1-3d = 191 -107\\\\\implies 4d = 84\\\\\implies d = \dfrac{84}4\\\\\implies d= 21\\\\\text{Substitute d= 21  in eq~(i):}\\ \\~~~~~ a_1 +3(21) =  107\\\\\implies a_1 + 63 = 107\\\\\implies a_1 = 107-63\\\\\implies a_1 =44

Use the drop-down menus to complete the statements. in order for f–1(x) to be a function, the domain of f(x) can be restricted t
zmey [24]

Using concepts of the inverse function, it is found that:

The domain of f(x) has to be restricted to x >= 1. Under this restriction, the domain of f-1(x), would be (2,∞), having the same minimum value as the original function f(x).

<h3>How to find the inverse of an equation or a function?</h3>

To find the inverse, we have to exchange x and y and then isolate y. This can only happen if the function f(x) is injective, that is, each value of the output is related to only one value of the input. Then:

  • The domain of f(x) is the range of the inverse function f-1(x).
  • The range of f(x) is the domain of the inverse function f-1(x).

Researching this problem on the internet, we are given an absolute value function with vertex at x = 1, meaning that for the inverse, the domain of f(x) has to be restricted to x >= 1. The domain of the inverse would be the range of f(x), which is (2,∞).

Then:

The domain of f(x) has to be restricted to x >= 1. Under this restriction, the domain of f-1(x), would be (2,∞), having the same minimum value as the original function f(x).

A rectangle has a perimeter of 82. If the width of the rectangle is one less than twice the length , find the width of the recta
Volgvan

Answer:

ans:- 14

Step-by-step explanation:

let length = x

so, width= 2x -1

perimeter= 2(l +b)

82 = 2(x+ 2x-1)

41 = 3x - 1

3x = 42

x = 14
