Answer:
b. 7
Step-by-step explanation:
133÷y=19
=> 133 ÷ 19 = y
=> 7 = y
=><u> y = 7(Ans)</u>

Answer:
And using the second point we have this:
If we divide both sides by 18 we got:
And taking the square roof of 16 we got:
But on this case the negative solution not makes sense since the function is increasing so then the correct exponential function that pass through the points (0,18) and (2,288) is:
Step-by-step explanation:
We want to construct an exponential function given by this general form:
And we know that the function needs to pass for two points (0,18) and (2,288). Using the first point we have this:
And using the second point we have this:
If we divide both sides by 18 we got:
And taking the square roof of 16 we got:
But on this case the negative solution not makes sense since the function is increasing so then the correct exponential function that pass through the points (0,18) and (2,288) is:
For this case we have the following vector:
v = (- 8, 2)
Using product point we have:
v.v = (-8, 2). (- 8, 2)
v ^ 2 = (-8) * (- 8) + (2) * (2)
v ^ 2 = 64 + 4
v ^ 2 = 68
v = root (68)
v = root (4 * 17)
v = 2 * root (17)
Answer:
v = 2 * root (17)
