Answer:
64 times more paint will be needed since the volume of the second is 64 times the volume of the first
Step-by-step explanation:
If the original sphere is 12 cm diameter
its radius will be half this measure which is 12/2 = 6 cm
The new diameter is 4 times this, so its radius would be 4 times this and it is 24 cm
Now, the volume of the sphere means we have to raise the power of the radius by 3
The other terms in the formula remains the same for both, so we are simply comparing the radii
so we will have the difference in volume in times of multiples as ;
(24/6)^3 = 4 * 4 * 4 = 64
Answer:
c maybe i can barely read it :(
Step-by-step explanation:
The initial value of the graph is where . Thus, in this case, the initial value is 12.
The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:
- and are points on the graph
Let's use two points from the chart to find the slope:
In this case, the rate of change of the graph is 9.
For this case we must factor the following expression:
We have that the expression cannot be factored with rational numbers.
On the other hand, we can find the zeros, applying the quadratic formula we have:
Where:
Thus, the roots would be:
Answer:
the expression cannot be factored with rational numbers.
The general form of slope-point form of the equation of line is
y-y1 = m (x-x1)
here, x1, y1 = a,b
m = b
so,
y-b = b(x-a)
thats it!
