Answer:
A = 2
Step-by-step explanation:
If A = 4 when B = 88, we can divide both A and B by 2 to find their values.
88/2 = 44
4/2= 2
We can also check this by dividing 88 by 4 to figure out that A = 1 when B = 22
We can then multiply both the values of A and B to get a proportional relationship of A = 2, B = 44

Answer:
the equation of the circle is
Step-by-step explanation:
Recall that the equation of a circle is given by where r is the radius, and (h,k) is the center. Recall that given two points that are the endpoints of a diameter, the center of the circle is their correspondent midpoint. Also, recall that given points (a,b), (c,d) their midpoint is obtained by
In this case we are given the endpoints (-1,-9), (5,1). So the center of the circle is the midpoint obtained by . Recall that the radius of a circle is the distance from the radius to any of the points of the circle. So, the radius is the distance between the center and the point (-1,-9). We will calculate r^2, by using the distance formula. REcall that the distance between points (a,b), (c,d) is given by
. So, its square is
.
In our case,
So, the equation of the circle is
Answer:
(4,-5)
Step-by-step explanation:
Answer:
5%
Step-by-step explanation:
I = P × R × T
420 = 1400 × R/100 × 6
R = 420 / 84 = 5%
