Vector is a quantity having magnitude as well as direction
its important because these are best way to relate a relationship between speed acceleration velocity etc
and helps to understand how the world that is around u behave
so vectors are really important
hope it helps
X^2 - x - 20
(x + 4)(x - 5) <==
x^2 - x - 20.....the last sign, which is negative, tells me that one set is positive and one set is negative. The first sign, which is also negative, tells me that the larger number will be negative. Now u have to find 2 numbers, that when added equal -1 and when multiplied, equal -20....those numbers are -5 and 4. so ur answer is : (x + 4)(x - 5)

a.) Initial cost of renting the car is $100
b.) rate of change is slope, that is :
c.) Cost = C and distance = d
the equation will be :
A(n)=-1(-3^n)
3, -9, 27, -81
Answer:
Step-by-step explanation:
Okay so to find the domain and range we need to find the x values and the y values: the domain is x and the range is y. Therefore the start of our x values can be concluded as -5 and the end is 5, so our domain will be -5 < x < 5: Note, I couldn't put the less than or equal to symbol. SO now our range is the values that are up and down, the range does down at 1 and the range is the highest at 3 so we can determine the range is 1 < y < 3. This is a continuous graph, so there is continuous x values and y values in this graph, so it's simple to use the start and the end of the domain and range followed by the possible y and x values which is represented by y and x.
Hope this helps. :)
