Answer:
The model car is 10 inches long
Step-by-step explanation:
To solve this question, we use conversion of units
Feet to inches.
Each feet has 12 inches.
The car is 15ft long.
So the car has 15*12 = 180 inches.
.5 inches = 9 in.
Rule of three
.5 inches - 9 inches
x inches - 180 inches
The model car is 10 inches long

Answer:
Step-by-step explanation:
The vertex form of a parabola is given by:
, where V(h,k) is the vertex of the parabola.
The given parabola has vertex (1,1).
This implies that: .
Put these values into the vertex form equation.
The y-intercept of this parabola is: (0,-3).
This point lies on the parabola hence it must satisfy its equation.
The equation now becomes
To find the x-intercept, put y=0 into the equation:
Divide through by -4.
Take plus or minus square root of both sides.
or
or
Therefore the x-intercepts are:
To the nearest hundredth, we have
