Is there a picture i could see or something?
F(x) = x² - 81
Finding f⁻¹(x) the inverse function
Let y = f(x) and solve for x.
y = x² - 81
y + 81 = x²
x² = y + 81
x = √(y + 81)
Recall f(x) = y, that means x = f⁻¹(y)
x = √(y + 81)
f⁻¹(y) = √(y + 81)
Therefore f⁻¹(x) = √(x + 81)
Answer:
i am pretty sure that they are both congruent because if you look at it they both create a line that is diagonal and in the middle they meet at the letter H so yeahh I hope this was right can i please be brainliest? I am very good at math sooooo I am pretty sure this is correct and if its not please tell me what I did wrong and I will not complain one bit I will try to do better next time thanks :)))
Answer:
1/8 and 1/16
Step-by-step explanation:
The negative exponent just means to right the negative inverse.
For example:
4^-2 means 4^2 but in a fraction
the answer would be 1/16
Answer:
6.6 cm
Step-by-step explanation:
The tangent function relates the 35° angle, the adjacent side 12 cm, and the unknown opposite side, x.
We can write tan 35° = opp / adj = x / (12 cm)
Multiplying both sides by 12 cm isolates (solves for) x:
(12 cm)(tan 35°) = x Note that 35° is equivalent to 0.6109 radians.
Thus, x = (12 cm)(0.5484) = 6.58 cm, or 6.6 to the nearest tenth.
