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:
8*5=40
160/40=4
to recheck
V= LxWxH
V=8*5*4
V=160
Step-by-step explanation:
GOOD LUCK
Let us say that:
a = black kittens
b = white kittens
We know that:
a = 5 b
a + b = 25
Therefore:
5 b + b = 25
6 b = 25
b = 4.17
But we cannot have a fraction value for the number of
kittens, so round off:
b = 4
So a is:
a = 25 – 4 = 21
<span>Hence Zoe counts additional 1 black kitten.</span>
Answer: <
Step-by-step explanation: 2 < 3.3166247903554
Three times two thirds cancels out the denominator.
