Answer:
So the coordinates are
Step-by-step explanation:
For this case we assume that the line is given by this formula
We know that the general equation for a circle is given by:
Since the circle for this case is centered at the origin then h,k =0 and we have this:
(1)
For this case we can replace the formula for y from the line into equation (1) and we got:
We know from algebra that if we use this concept we got:
We can subtract 64 on both sides and we got:
Now we can divide both sides by 2 and we got:
And we can use the quadratic formula to solve this:
For this case and if we replace we got:
And we got
Now we just need to replace into the original equation for the line and we get the y coordinates like this:
So the coordinates are
Answer: x= 5
Step-by-step explanation:
Plug the second equation into the first equation’s y.
3x-2(-2x+7)=21
Then use distribution
3x+4x-14=21
Add 4x and 3x
7x-14=21
Then add 14 to both sides
7x=35
Divide by 7 to get x
35/7=5
x=5
The decimal that will be equivalent to the fraction 29/11 is: 2.63
Answer:
1.575
Step-by-step explanation:
This question has to do with making an approximation based on the diagram of the angle. Angle KLM is an obtuse angle meaning it is larger then 90° but is also less than 180°. The only choices that lie within this range are choices B and D. However, it is safe to assume that angle KLM is closer to 180° than to 90° based on the diagram, therefore the answer must be choice B.
I hope this helps.
