Answer:
=
Step-by-step explanation:
Given:
We have to find the value of the given fraction which can be done by dividing the denominator value with the numerator value
The power of 8 is '1', so, the value of numerator is 8.
The value of the fraction is calculated by dividing 3 by 8.
=
Answer:
Function and its inverse was graphed.
<u>Step-by-step explanation:</u>
y = -4x²- 2
To find the inverse function of y = -4x²- 2 we have to transform the formula to calculate x in terms of y.
y = -4x²- 2
-4x² = y - 2
x = √(y-2) / -4
Now we can change the letters to follow the convention that x is the independent variable and y is the function's value:
y = √(x-2) / -4
Now we have to draw the graph as,
It was side by side that is LHS is the function and the RHS is its inverse.
Answer:
Option D
Step-by-step explanation:
Given expression has been given as,
Option D will be the answer.
Ok, so;
Let me draw the figure here below:
We know that the area of a circle can be found using the next equation:
Area = πr².
Where r is the radius and π is a number.
So, the area of this circle, will be:
Area = π(1km)²
Area = π km²
