Answer:
HOPE THIS HELPS!!
Step-by-step explanation:
a) Double each term to get the next (ie 5+5=10...10+10=20 and so on)
b)5,120 (you have to double the previous term to get the next)
For the reasoning, I think that you said it well, you should restate your answer, for an example, start off like this: I agree with Diego because... and for number five, I'm not too sure, sorry.
Step-by-step explanation:
The equation that relates the distance from the focus and directrix to any point is
or
Since the directrix is a horizontal line, we will use the second equation.
The vertex lies halfway between the focus and directrix.
Since y=1, is perpendicular to the axis of symmetry, we are going to use the point (0,1) to represent the directrix.
Next, using the y values the number that lies between 7 and 1 is 4 so our vertex is
Our h is 0 and. k is 4.
To find p, the equation of the focus is
So we have
or
Answer:
In principle, there is no direct relationship between the area and the perimeter of a rectangle, but both are calculated taking into account the measure of its base and its height.
Thus, the perimeter is equal to the sum of the length of the base and the height of the rectangle, and this result multiplied by 2.
In turn, the area of the rectangle is equal to the multiplication of its base by its height.
So, for example, if the base of the rectangle measured 10 cm and the height measured 5 cm, the perimeter would be equal to 30 cm (10 x 2 + 5 x 2) and the area would be equal to 50 cm2 (10 x 5).
