Area of the rectangle= Length*Width
Area of the rectangle =
Answer:
0
Step-by-step explanation:
We have 2 points on a line so we can use the slope formula
m = (y2-y1)/(x2-x1)
= (4-4)/(-10-7)
= 0/-17
= 0
Answer:
X = 4
Step-by-step explanation:
Answer:
The first one
Step-by-step explanation:
g(x) = ax² + bx + c
Point (0,0):
0 = a.0² + b.0 + c
c = 0
Point (2,1):
1 = a.2² + b.2 + c
4a + 2b + c = 1
But c = 0. Then:
4a + 2b = 1
Another point: (- 2, 1):
1 = a.(- 2)² + b.(- 2) + c
4a - 2b = 1
{4a + 2b = 1
{4a - 2b = 1
4a + 2b = 4a - 2b
4a - 4a = - 2b - 2b
- 4b = 0
b = 0
4a + 2b = 1
4a + 2.0 = 1
4a = 1
a = 1/4
The formula is:
g(x) = (1/4)x²
I hope I've helped you.
It could be 820 thats rounded to the nearest tenth
if its supposedto be rounded to the nearest hundred its 800
