Answer:

Rate of Change is 1

Step-by-step explanation:

The Average rate of change is the ratio of change in y and the change in x

Hence

Avg Rate of Change = Change in y / Change in x

The two coordinates are

(-4,0) and (0,4)

Change in x = 0-(-4) = 4

Change in y = 4-0 = 4

Hence

Avg Rate of Change = 4/4

= 1

Answer = 1

Z=-302+19.3i?????????

mafiozo [28]

Answer:

I don;t know what the question is but I know that z is an imaginary number.

Step-by-step explanation:

z=-302+19.3i

that means that it doesn't represent an actual number but is imaginary.

An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25.

The perimeter of triangle rxa is 24. if rx= 4 and ra= 11, find xp and pa

BigorU [14]

Answer:
PA = 6.6 units
XP = 2.4 units

Explanation:
1- We are given that:
perimeter of RXA = 24 units
RX = 4
RA = 11
This means that:
XA = 24 - 4 - 11 = 9 units

2- For XA:
XA = XP + PA
XA = 9 units
This means that :
XP + PA = 9 units
XP = 9 - PA

3- Triangle angle bisector theorem:
"In a triangle, the angle bisector divides the opposite side into two segments that are proportional to the other two sides"

Applying this to the given triangle, we can set the ratio as follows:
$\frac{XP}{PA} = \frac{XR}{AR}$

We have:
XP = 9 - PA
RX = 4
RA = 11

4- Substitute with the givens in the above ratio and solve for PA as follows:
$\frac{9-PA}{PA} = \frac{4}{11}$

11(9-PA) = 4(PA)
99 - 11PA = 4PA
99 = 15PA
PA = 99/15
PA = 6.6 units

5- Substitute to get XP as follows:
XP = 9 - PA
XP = 9 - 6.6
XP = 2.4 units

Hope this helps :)
