Answer:
6
Step-by-step explanation:
We know that the Area=pi*r^2
We also know that the diameter is 8
Since r*2 = 8 you divide 8/2 and plug that into the radius. From there you solve the equation I gave you earlier and you get your answer!
Answer:
11/15.
Step-by-step explanation:
If we consider a right angled triangle we see that
in this case cos θ = sin (90 - θ) so the answer is 11/15.
Answer:
1. 1 point
2. The x-coordinate of the solution = 2/17
3. The y-coordinate of the solution = -16/17
Step-by-step explanation:
Given that the equation is of the form;
y = -2³×x and y = 9·x - 2, we have;
y = -8·x and y = 9·x - 2
1. Given that the two lines are straight lines, the number of points of intersection is one.
2. The x-coordinate of the solution
To find a solution to the system of equations, we equate both expression of the functions and solve for the independent variable x as follows;
-8·x = 9·x - 2
-8·x - 9·x= - 2
-17·x = -2
x = 2/17
The x-coordinate of the solution = 2/17
3. The y-coordinate of the solution
y = 9·x - 2 = 9×2/17 - 2 = -16/17
y = -16/17
The y-coordinate of the solution = -16/17.
