Standard form is ax^2+bx+c=0

First evaluate the exponent and expand (foil).
y= 3(x^2-4x+4)+1

Then distribute the 3
y= 3x^2-12x+12+1

Combine like terms
y=3x^2-12x+13

Final answer: 3x^2-12x+13=0

What is the slope of this skateboard ramp if it rises 1.2 meters above the ground and runs 4 meters horizontally at the base?
Nesterboy [21]
By definition, the slope is the inclination of a line in relation to the horizontal. It can be expressed in degrees, ratios and even in percent. Therefore, you can calculate it by applying the following formula:
 
 P%=(H/L)x100
 
 P% is the slope expressed in percent.
 H is the height (H=1.2 meters).
 L is the length (L=4 meters).
 
 When you substitute these values into the formula P%=(H/L)x100, you obtain the slope of the skateboard ramp:
 
 P%=(H/L)x100
 P%=(1.2 meter/4 meters)x100
 P%=0.30x100
 P%=30%

The volume of a cube decreases at a rate of 0.5ft cubed per minute. What is the rate of change of the side length when the side
DENIUS [597]
The solution to the problem is as follows:

a cube has sides s 

V = s^3 ---> differentiating 

dV/dt = 3s^2 * ds/dt 

0.5 ft^3 / min = 3 * (12ft)^2 * ds/dt 

(1/2) ft^3 / min = 3 * 144 ft^2 * ds/dt 

(144/6) ft^3 / ( ft^2 min ) = ds/dt 

<span>24 ft / min = ds/dt
