Answer:
A. 10cm
B. 8 times
Step-by-step explanation:
The question is on volume of a conical container
Volume of a cone=
where r is the radius of base and h is the height of the cone
Given diameter= 12 cm, thus radius r=12/2 =6 cm
h=10 cm
B.
If height and diameter were doubled
New height = 2×10 =20 cm
New diameter = 2×12 = 24, r=12 cm
volume =
To find the number of times we divide new volume with the old volume
I think it will take Elizabeth 17 minutes.
Y(y + 4) - y2 = 6
y2 + 4y - y2 = 6
4y = 6 ⇒ False
Answer:
The vertex of this parabola, , can be found by completing the square.
Step-by-step explanation:
The goal is to express this parabola in its vertex form:
,
where , , and are constants. Once these three constants were found, it can be concluded that the vertex of this parabola is at .
The vertex form can be expanded to obtain:
.
Compare that expression with the given equation of this parabola. The constant term, the coefficient for , and the coefficient for should all match accordingly. That is:
.
The first equation implies that is equal to . Hence, replace the "" in the second equation with to eliminate :
.
.
Similarly, replace the "" and the "" in the third equation with and , respectively:
.
.
Therefore, would be equivalent to . The vertex of this parabola would thus be:
.
Answer:

Step-by-step explanation:
If you break the fraction into a whole number it would be 5 and 10 minus 5 is 5. so x=5
