Answer:
look for the x-intercepts
Step-by-step explanation:
A "zero" is a value of x where the function value is zero. On a graph, that point is where the graph meets the x-axis. Every x-intercept is a zero of the function.
__
If there are no x-intercepts, then there are no real zeros. The roots (zeros) will be complex.
Answer:
Dot product. ... In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used and often called "the" inner product (or rarely projection product) of Euclidean space even though it is not the only inner product that can be defined on Euclidean space; see also inner product space.

Answer:
C = 5x + 8y + 15z + 1.5r + 15
Where C = cost for the family of 6
Step-by-step explanation:
Let:
x = number of children under 10
y = number of children 11-16
z = number of all others (16 and above)
r = number of rides
Cost:
Under 10 = $5
11-16 = $8
Above 16 = $15
Ticket Ride = $1.50
We have an additional $15 for parking
So from there, we can find the cost by getting the total:
Cost for each TOTAL
x x $5 $5x
y x $8 $8y
z x $15 $15z
r x $1.50 $1.50r
Constant : $15 for parking
So the expression would then be:
C = 5x + 8y + 15z + 1.5r + 15
Given:
6 family members
x = 3
y = 1
z = 2
r = 5
We fill in the formula
C = 5x + 8y + 15z + 1.5r + 15
C = 5(3) + 8(1) + 15(2) + 1.5(5) + 15
C = 15 + 8 + 30 + 7.5 + 15
C = 75.50
