PEMDAS
since we don't have exponentes or paretnahsees we do
muliplictaion or division whichever comes first (since division is just multiplication of a fraction)
addition or subtraction whichever comes first (since subtraction is adding a negative)
so
multiply/divide
0 times 3=0
9/3=3
now we have
5-0+3
add/subtract
5-0=5
5+3=8
answer is 8
For this case we must find the current height of Osian. For this, we use the following rule of three:
1.5 m ----------------> 100%
x -----------------------> 120%
From here, we clear the value of x.
We have then:

Answer:
The current height of Osian is given by:

DF congruent to AC and EF is common side
Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
