Answer:
Step-by-step explanation:
To write the quadratic in standard form, begin by writing it in vertex form
Where (h,k) is the vertex of the parabola.
Here the vertex is (-3,-1). Substitute and write:
To find a, substitute one point (x,y) from the parabola into the equation and solve for a. Plug in (-2,0) a x-intercept of the parabola.
The vertex form of the equation is .
To write in standard form, convert vertex form through the distributive property.
Answer:
D.21,600 kilograms
Step-by-step explanation:
The volume of the tank is Length x Width x Height (6*1.5*2.4)
So the volume is 21.6 cubic meters.
Therefore, there are 21.6 cubic meters of water.
The density of water is 1,000 kg per cubic meter. So multiply 1,000 to the number of cubic meters. (1,000*21.6)
The mass of the water in the tank is 21,600 kg
Answer:
<em>x = 16hours</em>
Step-by-step explanation:
Given
Total number of hours to watch the television a week is 2 hours, that is;
2hours =1 week
We are to find the number of hours to watch in eight weeks to meet the goal
x hours = 8 weeks
Divide both expressions;
2/x = 1/8
Cross multiply
1 * x = 2*8
x = 16
<em>Hence he will use 16hours to watch the television in 8 weeks </em>
