Answer:
A, C, and D
Step-by-step explanation:
Remember that in a function, every unique input must have one output. Therefore, two or more outputs cannot have the same input. Knowing this, we can eliminate choice B. Therefore, A, C, and D are correct.
Answer:
1, 2 and 4
Step-by-step explanation:
1.32m2/16m +48m/16m =2m +3
2.4m2/2m +6m/2m =2m+3
4.10m2 /5m +15m/5m= 2m+3
Answer: The first one is "translated 4 units down". The second one is "vertically stretched by a factor of 4".
Recall that y = f(x). When we say f(x)-4, we really mean y-4 so that means each y coordinate of all the points on the graph have been reduced by 4. Visually this shifts the graph down 4 units. A translation in geometry is the technical term for shifting.
When we say 4*f(x), we are multiplying each y coordinate by 4. A point like (1,2) turns into (1,8) for instance. If you apply this to every point on the graph, then the curve is stretched vertically to be 4 times taller than it usually is; which is an informal way of saying "vertically stretched by a factor of 4"
Personally the easiest way for me is to first find the area of the rectangle and take away the missing triangles. So assuming it’s a rectangle we get (4+5)(3+2) = 45. Ok now we find the area of the triangles. 0.5(4)(3) = 6. Now we subtract that twice from our 45.
45-6-6 = 33. The answer is 33
Answer: 117
Step-by-step explanation:
Formula for arithmetic sequence is:
= a + (n - 1)d
22nd term = a + (n - 1)d
= a + (22 - 1)d = a + 21d
where, a = 12
d = 17 - 12 = 5.
Therefore, 22nd term will be:
= a + 21d
= 12 + 21(5)
= 12 + 105
= 117
The 22nd term is 117
