Answer:
The formula would be to divide the length value by 100
, yielding 4.21 meters.
Step-by-step explanation:
Answer:
D)Both parabolas open to the right, and
is wider than 
Step-by-step explanation:
Standard equation of parabola :

If a < 0, then the parabola open downwards and if a > 0, then the parabola open upwards.

If a < 0, then the parabola open left and if a > 0, then the parabola opens right
Given equations :
and 
and 
in both the equations a>0
So, Both parabolas are open to the right.
Refer the attached graph
---- Red
--- blue
So,
is wider than 
So, Option D is true
Answer:The scale is 1:12, and the actual car has 16-in wheels.
Step-by-step explanation:
So the setup would be a proportion:
1 over 12=x over 16
Then cross-multiply
12x=16
Divide by 12
X=16/12
=4/3 or 1 and 1/3 in. wheels on the model car.
Answer:
X=8
Step-by-step explanation:
Since it has a tangent and a radius you could use the Pythagorean Theorem to find your x. This is what it would look like:
Step-by-step explanation:
1: Solve one Equation for one of the variables
2: Substitute (plug-in) this expression into the other equation and solve
3: Resubtitue the value into the original equation to find the corresponding variable
