An ophthalmologist is a doctor that specializes in the eye or eyeball.
The first one is neither
No. 2 is perpendicular ( because slope = -1/ slope of the other)
No 3 is parallel (both have slope of 3/4)
No 4 is perpendicular.
Answer:
Step-by-step explanation:
The best way to do this is to let a graphing program do it. You could do it from a chart, but a graphing program can be useful for that as well. We'll make up a mini chart here
x method y
-3 (-3)^2 + 2(-3) + 3 = 6
-2 (-2)^2 + 2(-2) + 3 = 3
-1 (-1)^2 + 2(-1) + 3 = 2
0 3
1 (1)^2 + 2(1) + 3 6
2 (2^2) + 2(2) + 3 11
3 (3)^2 +2(3) + 3 18
See the graph below.
You can pick it out from the graphs you were given.
Answer:
93.6
Semi circle - 31.81 (rounded)
Step-by-step explanation:
find the area of the triangle which is 1/2 6*5.2 -=15.6
there are 6 triangles so that means it has to be multiplied by 6 - 15.6*6 = 93.6
Use the semi cirlce formula- (pi*r^2)/2
In this situation that is (pi*4.5^2 )/2 = 31.81 (rounded)
The answer is 3,750. you would multiply 1250 by 3
