How to calculate the distance between two points</h3>
The formula for calculating the distance between two points is expressed as:
A = √(x2-x1)²+(y2-y1)²
Given the coordinate points X(–12, –6) and Y(5, 6). The distance between them is expressed as;
XY = √(5+12)²+(6+6)²
XY = √(17)²+(12)²
XY = √269 + 144
XY = 20.8
Hence the approximate length of line segment XY is 20.8 units

Answer: The answer is 3573.64
Step-by-step explanation:
Exponential Functions:
y=ab^x
a=starting value = 19000
r=rate = 11.25%=0.1125
Exponential Decay:
b=1-r=1-0.1125=0.8875
Write Exponential Function:
y=19000(0.8875)^x
Plug in time for x:
y=19000(0.8875)^14
y= 3573.6388855
Evaluate
:
y≈3573.64
I'll solve it algebraically
x+y=4
x-3y=12
multiply first equatoin by -1 and add to second
-x-y=-4
<u>x-3y=12 +</u>
0x-4y=8
-4y=8
divide both sides by -4
y=-2
sub back
x+y=4
x+-2=4
add 2 to both sides
x=6
x=6
y=-2
(6,-2)
