Answer:
<h2>
f⁻¹(x) = ∛(x+1)</h2>
Step-by-step explanation:
Given the encoded message defined by the function f(x) = x³-1, the inverse function that the decoder would need when the message is received can be expressed as thus:
let the inverse of the function be represented as y such that y = x³-1.
Making x the subject of the formula from the equation above;
x³ = y+1
Taking the cube root of both sides:
∛x³ = ∛(y+1)
x = ∛(y+1)
replacing y with x:
y = ∛(x+1)
f⁻¹(x) = ∛(x+1)
The encoded message is the inverse function ∛(x+1)
Answer:
no, because the first=12-x
and the second=-1x+2
Step-by-step explanation:
The values of the three angles in the given triangle are; B = 14.583°;
A = 77.917°; C = 87.5°
<h3>What is the sum of angles in the triangle?</h3>
We are told that the measure of angle C is six times the measure of angle B. Thus, this can be expressed as;
C = 6B
We are told that 4 times angle A is 20 more than 20 times angle B. Thus, this can be expressed as;
4A = 20B + 20
Divide through by 4 to get;
A = 5B + 5
No, we know that sum of angles in a triangle is 180°. Thus;
5B + 5 + B + 6B = 180
12B + 5 = 180
12B = 180 - 5
12B = 175
B = 175/12
B = 14.583°
A = 5(175/12) + 5
A = 77.917°
C = 6 * 175/12
C = 87.5°
