Answer:
21b+21
Step-by-step explanation:
1. simply, combine like terms
3b t 18b +21
add 3b and 18b
it gives u 21b +21
18.614 because a=πh(r^2)/3 pretty sure thats the formula but the answer is correct
Answer:
(0, 6)
Step-by-step explanation:
Point T has a coordinate pair of (3, 4). That is, at point T, x = 3, while y = 4.
3 points to the left of T would be a movement on the x-axis. This movement is a run across the x-axis. At T, x = 3. Therefore, 3 points to the left would be a decrease by 3 = 3 - 3 = 0.
3 points to the left of T would leave us with an x coordinate of 0.
2 points above T suggest a rise, which is on the y-axis.
Therefore, at T, y = 4. 2 points above 4 = 4 + 2 = 6. y coordinate would now be 6.
In conclusion, the ordered pair representing 3 points to the left, and 2 points above point T is (0, 6).
Answer:
Step-by-step explanation:
The first number is 
We simplify to get:
The second number is .
This number can be rewritten as 
This is not an integer
The third number is 
We simplify to get: 
This is also an integer.
The correct answer is .
The graph of this sinasoid wave is B) f(x) = 3cos(x) + 3
We can tell this for two reasons. Firstly, the multiplier in the beginning is always equal to half of the height of the graph. Since the graph goes as high at 6 and as low as 0, we know the overall height is 6. Half of that is 3. This means that we have a 3 for the multiplier.
Next, we can decide between sin and cos by determining that it starts up and ends down. Sin starts moving up at the beginning and cos moves up at the beginning. Therefore, it must be the cos.
