Answer:
15
Step-by-step explanation:
The amount of water displacement would be equivalent to the volume of the rock, which is 1800. We find this by doing 10 x 12 which is 120. Now we can divide 1800 by 120, which is 15. Giving us the dimensions 10 x 12 x 15.
Answer:
Option B
Step-by-step explanation:
we know that
The critical point of a function are the points on the graph of a function where the derivative is zero or the derivative does not exist.
we have
step 1
Take the derivative of the function
step 2
Set that derivative equal to 0 and solve for x. Each x value you find is known as a critical number
<em>Alternative Method</em>
The critical point of the quadratic equation is the vertex, because the function changes from decreasing to increasing at that point (In this problem the vertex is a minimum)
we have
Convert into vertex form
the vertex is the point (-2,-15)
therefore
The x-coordinate of the critical point is x=-2
Answer:
f(x) = 3x + 26; 26 ≤ y ≤ 35
Step-by-step explanation:
This makes a linear equation.
y=mx+b
where m is the amount they want to increase each week
and b is the initial value i.e 26 clients.
Now substitute the values in the equation.
Let x=0
y=3(0)+26
y = 26
Now let x= 3
y=mx+b
y=3(3)+26
y=9+26
y=35
Thus the correct option is B.
f(x) = 3x + 26; 26 ≤ y ≤ 35 .....
Answer:
The percent charge of Kanna's DS is 50%
Step-by-step explanation:
we know that
A Nintendo DS takes 4 hours to charge fully (100%)
4 hours is the same that 240 minutes
using proportion
Find out what percentage represent 108 minutes
Remember that
Kanna Kamui charge her DS from 5%
so
therefore
The percent charge of Kanna's DS is 50%
