Answer:
10 experiments
Step-by-step explanation:
Given:
Amount of substance A = 
Amount of substance B =
Total amount of mixture = 
Now, amount used for each experiment = 
So, number of experiments conducted = 
Therefore, the number of experiments conducted are 10.
Answer:
initial value is 15
growth factor is 1.25
Step-by-step explanation:
we are given
The number of members f(x) in Joe's health club
increased by 25% every year over a period of x years
The function below shows the relationship between f(x) and x as

now, we can compare it with exponential function

where
a is the initial value
b is growth factor
we can compare and find 'a' and 'b'

So,
initial value is 15
growth factor is 1.25
we know that
x is time
so, it can never be negative
f(x) is number of chambers
so, f(x) can not be negative
now, we can draw graph
and we get as
J/-2 + 7 = -12 multiply both sides with 2
-j + 14 = -24 move -14 to the other side and change sign
-j= -24 - 14
-j = -38 and if you divide -38 with -1 you get + 38
j=38
Answer:
ABC is a right angle
Step-by-step explanation:
ABC = 25+ 65
ABC = 90
We know that 90 degrees is a right angle
