Answer:
Can you provide the image? Then I can probably answer
Step-by-step explanation:
A quadratic equation may be expressed in vertex form as:
y = a(x - h)² + k, the vertex being (-h , k)
For option A, the vertices are visibly different. (-4 , 0) and (4 , 0)
For B, the graphs' vertices are the same, (0 , 0).
For C, the vertices (can be obtained by differentiating and putting equal to 0) are (0 , -4) and (0 , 4)
For D, the vertices are (4 , 0) and (0 , 4)
Thus, the answer is B.
To solve this you simply divide .505 by 1 (0.505/1) and then multiply by 1000/1000 to get rid of the decimal, giving you 505/1000. If you want to return to decimal form you divide 505 by 1000.
Hope this helps!
Answer:
D)
Step-by-step explanation:
First we want to find the diameter of the circle, since we are only given coordinates we have to find the distance between these points this gives us the diameter.
| -3 + 3 | = 6 (|| = positive value)
The diameter is 6 now we can draw a inscribed square with each corner touching the circumference of the circle at 0,90,180,and 360 degrees.
To find the length of one side we have to use the radius of the circle with Pythagorean theorem.
3^2 + 3^2 = c^2 ; 18=c^2
sqrt = square root
Then square root both sides; sqrt(18) = sqrt(c^2)
sqrt(9) * sqrt(2) = sqrt(c^2) ; 3*sqrt(2) = c
This is one length to find the others we just multiply by four since the sides length of a square are all the same as each other. 4*(3*sqrt(2)) = Perimeter
12*sqrt(2)
Answer:
-12 and 4
Step-by-step explanation:
-12 x 4 = 48
and
-12 + 4 = -8
