Answer:
The equation in vertex form is:

Step-by-step explanation:
Recall that the formula of a parabola with vertex at
is given by the equation in vertex form:

where the parameter
can be specified by an extra information on any other point apart from the vertex, that parabola goes through.
In our case, since the vertex must be the point (2, 1), the vertex form of the parabola becomes:

we have the information on the extra point (0, 5) where the parabola crosses the y-axis. Then, we use it to find the missing parameter
:

The, the final form of the parabola's equation in vertex form is:

You need to figure out how many ways you can roll a sum of 9.
3 and 6, 4 and 5, 5 and 4, and 6 and 3. That's 4/36, or a 1/9 chance.
Alex has a 1/6 chance. Therefore, Alex is more likely to win.
Answer:
23 miles
Step-by-step explanation:
12.76=13
3.45=3
6.52=7
13+3+7=23
Answer:
speed=24km/h or 6.67m/s
Step-by-step explanation:
Given data:
time taken = t =43 hours
distance covered = d = 1032 km
to find:
speed of the ship = v =?
solution:
as we know that speed is defined as the distance covered by an object in unit time.Formula
speed = distance covered /time taken
speed = 1032km/43hours
speed =24km/h or in international system of units the answer is 6.67m/s
