Answer:
Yes, the distance from the origin to the point (8,√17) is 9 units.
Step-by-step explanation:
The equation of a circle centered at the origin with radius , r has equation:
Since the circle passes through (0,-9), the radius is 9 units because (0,-9) is 9 units from the origin.
We substitute the radius to get:
If (8,√17) lies on this circle, then it must satisfy this equation:
This is True.
This means the distance from (8,√17) is 9 units from the origin.
Answer:
30 pounds of raspberries and 50 pounds of blueberries
Step-by-step explanation:
Let's use b to represent blueberries and r for raspberries. Each pound of raspberries costs $1, so to find the total cost of raspberries we use 1r, which is just r. For blueberries, we do 3.25b.
r+3.25b=192.5
We also know that we can combine the numbers for 80 total pounds.
r+b=80
We can subtract the two equations we have made to eliminate the r and solve for b.
2.25b=112.5
We divide both sides by 2.25.
b=50
We know that r+b=80, so if b is 50 then r must be 30.
Have a wonderful day! :D
Answer:
70.4x60
Step-by-step explanation:
It’s the position on the graph. So quadrant 1 is (x,y)
Quadrant 2 is (-x,y)
Quadrant 3 is (-x,-y)
Quadrant 4 is (x,-y)
