Answer:
7987.1569 to the nearest thousandths is 7987.157
Step-by-step explanation:
Answer: There is one solution to the given equation.
Step-by-step explanation: We are given to find the number of solutions to the following equation :
Since the given equation is linear in one variable x, so it will have only one solution.
The solution of equation (i) is given by
Thus, there is one solution to the given equation.
To find the inverse of this function, we first need to replace f(x) with y.
y = 2x^2 + 3
Now, we swap x and y
x = 2y^2 + 3
Now, we solve for y.
-3
x - 3 = 2y^2
Sqrt both sides.
√(x - 3) = 2y
Divide by 2
√(x - 3)/2 = y
Replace y with f^-1(x)
√(x - 3)/2 = f^-1(x)
Just realized you were asking for f(-1), not f^-1(x)
Feels bad.
f(-1) = 2(-1^2 + 3)
f(-1) = 2(-1^5)
f(-1) = 2(-1)
<u>f(-1) = -2</u>
I'm leaving the original answer in case you also need the inverse function. :)
Answer:
The answer is the first one - 8 square roots of 3
Step-by-step explanation:
Using formula is sufficient here.
In hexagon there are 6 same triangles.
You calculate the area of one of them by formula (1/2)*(2)*(4square root of 3/3)
You multiply that by 6 and simplify.
The answer is the first one - 8 square roots of 3
