Answer:
Q(18) is a mathematical representation of the weight in pounds of a puppy after 18 months.
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds
Step-by-step explanation:
Given the expressions :
Q(18)
Q(30) = 27.5
Function Q gives a puppy's weight in pounds as function of its age in months
What does each expression represent in this situation?
A function is generally represented in the form a(x) ;
Hence, Q(18) is a mathematical representation of the weight in pounds of a puppy after 17 months
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds. 27.5 is the result of working out the function Q at 30.
Answer:
2x³ + 12x² + 10x - 24
Step-by-step explanation:
(2x² + 6x - 8)(x + 3) Distribute
2x³ + 6x² + 6x² + 18x - 8x - 24 Combine like terms
2x³ + 12x² + 10x - 24 This expression is in standard form

Answer:
6kg pure copper and 30 kg 10% copper was mixed to give 36kg of 25% alloy
Step-by-step explanation:
Here, we want to produce 36 kg of 25% alloy
Let the Pure copper be x kg while 10% alloy be y kg
Pure copper is simply 100% copper
Thus;
x + y = 36 •••••(i)
Then;
100% of x + 10% of y = 25% of 36
= x + 0.1y = 9 •••••• ii)
From i x = 36-y
from ii, x = 9-0.1y
Equate both x
36-y = 9-0.1y
36-9 = 0.1y + y
0.9y = 27
y = 27/0.9
y = 30
x = 36-y
x = 36-30
x = 6 kg
