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.
We need to use Law of sine.
sin A/a = sin C/c
sin A/|CB| = sin C/|AB|
sin A/14 = sin(118⁰)/ 20
sin A = (14*sin(118⁰))/ 20
A=arcsin((14*sin(118⁰))/ 20) ≈ 38⁰
Answer:
Option b is the correct answer
Step-by-step explanation:
The graph in the picture is the graph of a quadratic equation and it takes the shape of a parabola.
The points on the x axis through which the parabola cuts across is used to determine the solution of the quadratic equation.
Looking at the parabola formed from the plotted points, it cuts the x axis at
x = -1 and x= -2
These are the factors of the equation. To get the equation, we multiply the factors.
x= -1, x +1 = 0
x =-2 , x + 2= 0
The equation is (x+1)(x+2)
Expanding the brackets,
x×x + x×2 +1×x + 1×2
= x^2 + 2x + x +2
= x^2 + 3x +2 = 0
Option b is the correct answer
