Answer:
Step-by-step explanation:
y = arctan(x+pi/2) use that tan y = x is y= arctan x
tan y = x+pi/2; change x with y and find y
tan x= y +pi/2; subtract pi/2 from both sides
-pi/2 + tan x = y
y= tan x -(pi/2) is the inverse function
you can also write it as
y = 1/2(2 tan x -pi)
If the negative exp is in the numerator put it in the denominator and make it positive. if it's already in the denominator move it to the numerator and make it positive
examples. x^-3 = 1/x^+3
a/(c*b^-2 ) = ab²/c
hope that helps!
Answer:
12 sq u
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, assuming the shaded triangle is one of those two triangles, its area would be 12 sq u.
Why? Because its length would be the same as the retances, as would its height, and to find the area of a triangle, you'd do L*H/2 which would be 24/2=12 sq u

Answer: 2.45
Step-by-step explanation:
12.25/5 = 2.45
Answer:
<u>Part A:</u><u> x = -24</u>
<u>Part B: </u><u>n = 2</u>
Step-by-step explanation:
<u>Part A:</u>
The algebraic expression for: "StartFraction 2 Over 3 EndFraction left-parenthesis StartFraction one-half EndFraction. x plus 12 right-parenthesis equals left-parenthesis StartFraction one-half EndFraction left-parenthesis StartFraction one-third EndFraction x plus 14 right-parenthesis minus 3" will be ⇒
Multiply both sides by 6
∴
∴
∴ 2x + 4*12 = x + 3 *14 - 18
∴ 2x - x = 3 * 14 - 18 - 4 * 12 = -24
<u>∴ x = -24</u>
============================================================
<u>Part B:</u>
The algebric expression for: "StartFraction one-half EndFraction left-parenthesis n minus 4 right-parenthesis minus 3 equals 3 minus left-parenthesis 2 n plus 3 right-parenthesis" will be ⇒
Multiply both sides by 2
(n-4) - 6 = 6 - 2(2n+3)
n - 4 - 6 = 6 - 4n - 6
Combine like terms
n + 4 n = 4 + 6
5n = 10
n = 10/5 = 2
<u>∴ n = 2</u>
