The functions in part A are correct, we will now use them to solve for part B.
We equate the numbers of the trees in order to find x, which the number of years after which they will be equal.
800(0.95)ˣ = 50(1.15)ˣ
40 = (1.15 / .95)ˣ
Taking log₁₀ on both sides,
log(40) = x*log(1.15/0.95)
x = 19.31 years
Answer:
l.c.m of 15 and 5 is 15
next step is to equalize the denominator with the l.c.m value
11/15 is the same (same denominator)
3/5 will change to 9/15 (multiply numerator and denominator by 3 to equalize)
Lastly, you just need to subtract
11/15 - 9/15
2/15
Part A: the value of x is 0 because anything to the zero power is 1
part B: x can be any number. 6 to the 0 power is 1 and 1 to any power is 1
Point a is at (-2,4) => (x1,y1)
Midpoint is (2.5, 3.5) => (a,b)
Point B is (x2, y2)
To find midpoint we use formula
a= 2.5, b= 3.5, x1= -2 and y1= 4
Plug in all the values and findout x2, y2
multiply 2 on both sides to remove fraction
(5 = -2+x2 , 7 = 4+ y2)
5 = -2+x2, so x2= 7
7 = 4+ y2, so y2= 3
The point B is ( 7, 3)
