Answer:
Step-by-step explanation:
Solving (c): The rate of change:
In this concept, the formula to use is:
Where
----- In 2004
------ In 2026
So, we have:
52 tests because you would multiply 28 by 100 then divide by 54. You would get 51.851, but you cannot have and 8th of a test, so you would round up
The answer could be negative or positive. We are not given specific as to whether or not the starting number is positive or negative so therefore it could be either.
Hope this is helpful :)
X intercept is when the function (y) = 0.
0 = 4 - (x+3)^2
(x+3)(x+3) = 4
x^2 + 6x + 9 = 4
x^2 + 6x + 5 = 0
To factor, we find what multiplies to 5 and adds to 6. In this case, it’s 5 and 1.
(x+5)(x+1) = 0
x values of the intercepts are -5 and -1.
The coordinates are (-5,0) and (-1,0).
