It is possible to test if a quadrilateral is a square by performing calculations on its diagonals, in this case, AC, and BD. A quadrilateral is a square if all three of the following conditions are true

The diagonals intersect at their midpoints.
The diagonals are both the same length.
The diagonals are perpendicular.
Based on this information, is the figure below a square?

If so, give the results of all calculations that allow you to verify that it is.
If it is not a square, describe which condition or conditions are not met.
5Points
A cartesian coordinate plane with the vertical axis labeled y from negative 20 to 9 and the horizontal axis labeled x from negative 14 to 17. Point A is at the point negative 4 comma 6 and point B is at the point negative 12 comma negative 12. The points form segment A B. Point C at the point 6 comma negative 18 forms segment B C. Point D at the point 13 comma negative 1 forms segment C D and D A.
Your response should contain at least 3 complete sentences.

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

5/20 so 25%

step-by-step explanation:

a) 40 more; b) old factory:   10%, new factory:   16%; c) week 4

explanation:

a) at week 0, we see in the graph that the new factory produces 190 specialty items.  

using the function, substituting 0 in for w,

this is a difference of 230-190 = 40.

b) the function for the old factory is written in the form f(x) = a(1+r)ˣ, where a is the original amount, x is the amount of time and r is the growth rate.   the equation for the old factory is ; 230 is in place of a and is the original amount; w is the amount of time; which means 1+r = 1.1.   this means that r must be 0.1 or 10%.

for the new factory, we find the percent of increase to find the growth rate; the formula for this is

between the first two points, the amount of change is 220-190 = 30; this gives us

30/190 = 0.158 ≈ 0.16 = 16%

c) at week 0, the old factory has 230 while the new factory has 190.

at week 1, the old factory has 230(1.1) = 253 while the new factory has 220.

at week 2, the old factory has 230(1.1²) = 278.3 while the new factory has 252.

at week 3, the old factory has 230(1.1³) = 306.13 while the new factory has 290.

at week 4, the old factory has 230(1.1⁴) = 336.743 while the new factory has 337.   this is the first week that the new factory surpasses the old.
