Answer:
an obtuse angle is greater than 90 and if you think about it 90 plus 90 equals. 180 so if you had two obtuse angles both greater than 90 you would have more than 180 degrees. so the answer for how many angles. of two are in an obtuse triangle is one right here.
Answer:
7×7×7
Explanation:
When a number is raised to a power, it means that the number is multiplying itself as many times as the number written as the power.
Answer:
The first option
Step-by-step explanation:
Step-by-step explanation:
I will do the first one as an example.
To find the inverse of y = f(x), simply switch x and y, then solve for y.
y = 3 + 2 ln x
x = 3 + 2 ln y
x − 3 = 2 ln y
(x − 3) / 2 = ln y
y = e^((x − 3) / 2)
So the inverse function is:
f⁻¹(x) = e^((x − 3) / 2)
The original function told us the amount of water as a function of time.
The inverse function tells us the time as a function of the amount of water.
