Step-by-step explanation:
let the unknown members be X
At first, the club had 20 + X members
After the first year,
2( 20+X)
The second year,
2( 20 +X/2) +40
The third year,
3[2(20+ X/2) +40]
Total number =
20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]
= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]
= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]
= 60 +3X +80+X + 3[80+X]
= 140+4X + 240+3X
=380 + 7X
-380=7X
X = -54.3
Answer:
5.89 mL
Step-by-step explanation:
doctor prescribed = 0.75 ml (2x a day) = 1.5 mL
pharmacist labeled = 3/4 teaspoon (0.75 teaspoon (2x a day) = 1.5 teaspoon
convert 1.5 teaspoon to mL = 7.39 mL
therefore,
the excess medication given in one day = 7.39 mL - 1.5 mL = 5.89 mL
Answer:
C. 726
Step-by-step explanation:
9196-1936=7260 and take away the 0 so your answer will be 726
4.5a-18b+15

We have the following function:
So if we graph this function we will get the Figure below. Thus, let's study both the equation and the graph to get some conclusions. Therefore, we can assure these statements:
First. The function is defined only for
as shown in the Figure. This is also true because of
where
must be greater (or equal) than zero.
Second. The range of the function are the values of
.
Third. If
creases then
always creases, too.
