Answer:
so i would say the first one
Step-by-step explanation:
so how i got it is i done it on paper and figured it out it took me a bit and it hurt my fingers trust me most of my answeres are correct
The graph is crossing the x-axis at x = - 4 .
If you observe the graph it is touching x = -4 and turning away. When graph exhibit such a behavior we say that the multiplicity of the root is 2. This means the root x = -4 occurs two times. So the factors of the polynomial are x + 4 and x + 4
So the given polynomial can be expressed as (x+4)(x+4).
Thus, the correct answer is option A
Answer:
Time(min)
2
6
8
15
Distance(km)
6
18
24
45
Step-by-step explanation:
the time is 1/3rd of the distance. it's a 1:3 ratio
Option C is the correct answer
So let's help Mr. Dawson to demonstrate why.
The functions model the cost of the plot of land after x years, so we need to find the cheaper option. Therefore:
Cost of the option A:Cost of the option B:
Cost of the option C: This is the cheaper option
