-1154
Step-by-step explanation:
(-554) - 600 = -1154
Answer:
SAS
Step-by-step explanation:
the angles are congruent, and the 2 pairs of sides are proportional.
200/150 is 4/3 and 320/240 is 4/3 as well.
therefore Side-Angle-Side
Suppose that the height of the tree is given by exponential growth. This is the given by the form:
y=abˣ
where:
a is the initial value
b is the growth factor
y is the current value
x is the number of years.
From the question:
a=36 in
b=1 1/4=1.25
y=44 3/4=44.75
plugging the values in the equation we get:
44.75=36(1.25ˣ)
solving for x we shall have:
179/144=1.25ˣ
introducing logs
ln(179/144)=x ln 1.25
hence
x=[ln(179/144)]/ln 1.25
x=0.975~ 1 year
Answer: the tree was planted 1 year ago
Notice that
is the same as
. Using a graphing utility we can graph the inqueality as shown in the picture.
