Answer:

80 cm²

Step-by-step explanation:

Given 2 similar figures with sides in the ratio a : b , then

ratio of areas = a² : b²

Here ratio of sides = 7 : 14 = 1 : 2

ratio of areas = 1² : 2² = 1 : 4

Thus area of B is 4 times area of A

area of B = 4 × 20 = 80 cm²

It should be noted that the relationship is not linear based on the information illustrated as the difference between the numbers aren't the same.

<h3>How to illustrate the information?</h3>

It should be noted that an equation is simply used to illustrate and express the relationship between the variables.

It should be noted that for the relationship to be linear, it's essential that they've the same relationship between them.

When x = 1, y = 4.5. The

When x = 2, y = 6.5

When x = 3, y = 8.5

When x = 4 y = 11.5

It should be noted that there's a difference of 2 at first but between 3 and 4, there is. a difference of 3.

Therefore, the relationship is not linear.

Use the graph to answer the question. About how many more website hits were there on Tuesday than on Monday? A. 700 B. 400 C. 60
nadezda [96]
In this graph, each day has its own graph, starting at the bottom with Monday, to the top at Sunday. To know how many hits each day had, go to the end of the graph, and the closest number at the bottom is how many hits there were. This graph states that there were around 1900 hits on Tuesday, and 1300 on Monday. To get the answer we then take the difference, getting 600.

What is the equation of a parabola with (-1,-3) as its focus and y=1 as its directrix?
Olegator [25]
Hmm, y=1 is directix
means it opens up or down
we will be using
(x-h)²=4p(y-k) where (h,k) is vertex and p is the distnace from focus to vertex and from vertex to direcitx
focus is (-1,-3)
find distance between y values because directix is a y value
midpoint is the vertex
from -3 to 1 is 2 units
since focus is below directix, it opens down, and p is negative
it is 2 units above focus
so at (-1,-1)
and p=-2

(x-(-1))²=4(-2)(y-(-1))
(x+1)²=-8(y+1) is da equation
