Let's compare the given function with the model for a quadratic equation:
Since the value of a is positive, the parabola has its concavity upwards, and the function has a minimum value.
The minimum value can be found calculating the y-coordinate of the vertex:
Therefore the minimum value is -24.
Answer:
I think it is C
Step-by-step explanation:
Have a good toseday
1. find volume
V=LWH
V=25*13*14
V=4550
each covers 1000
how many will cover the whole thing?
we can't put 4 becuase that leaves 550 uncovered
add another
5 is answer (it is too much , but at leas not too little) answer is D
2.
V=LWH
V=6*4*10
V=240
answer is D
3. count how many are there, don't forget the hidden ones
13 cubes
volume=legnth tiems width times height
cubes so
v=side^3
side=3
3^3=27
13 cubes
13*27=351 in^3
challenge (this is meant to challenge you, not for you to ask people, but I will solve anyway, robbin you of experience)
V=LWH
V=5880
H=30
5880=LW30
divide both sides by 30
196=LW
they have square bases so L=W
196=L^2
sqrt both sides
14=L=W
the side legnth is 14in
Given:
are in geometric sequences.
To find:
The value of x.
Solution:
If a, b, c are in geometric sequences, then
...(i)
It is given that are in geometric sequences. By using (i), we get
On further simplification, we get
Therefore, the value of x is 0.
A: parallel
B: perpendicular
C: neither
D: perpendicular
E: parallel
Explanation: Parallel lines have the same slope. Perpendicular lines have inverted and converted slopes. Neither has neither.
