A model car has a scale factor of 1/64. The diameter of a tire on the model is 0.39. So, the diameter of the tire on an actual c
Andre45 [30]
Answer: 24.96 inches.

This model car is having 1/64 scale which means the actual car is 64 times longer. To know the diameters of the actual car, you just need to divide the diameter of model car with the scale. If the diameter of the model is 0.39 inch then the calculation is:
Diameter of actual car x scale = diameter of model 
Diameter of actual car = diameter of model / scale = 0.39 inch / (1/64)=  24.96 inch.

F(x)=3/2(x-2)^2-24 <br>put this in standard form​
gregori [183]

Answer:

f(x) = 3x^2 - 12x -  36.

Step-by-step explanation:

f(x) =3 /2(x - 2)^2 - 24

f(x) = 3/2 (x^2 - 4x + 4) - 24

f(x) = 3/2 x^2 - 6x + 6 - 24

f(x) = 3/2 x^2 - 6x - 18

Multiply through by 2:

f(x) = 3x^2 - 12x -  36.

A circle centered at (-2,3) and contains point (5,9) which represents the equation
SIZIF [17.4K]
The standard form of the equation of a circle is (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center of the circle, (x,y) is a point of the circle, and r is the length of the radius of the circle. When the equation of a circle is written, h,k, and r are numbers, while x and y are still variables. (x-2)^2 + (y-k)^2 = 16 is an example of a circle. The problem gives us two of the three things that a circle has, a point (5,9) and the center (-2,3). We need to find the radius in order to write the equation. We substitute -2 for h, 3 for k, 5 for x, and 9 for y to get (5 - (-2))^2 + (9 - 3)^2 = r^2 We simplify: 49 + 36 = r^2, r^2 = 85. We only need to know r^2 because the equation of a circle has r^2. We now have all the information to write the equation of a circle. (x + 2)^2 + (y - 3)^2 = 85.
