Answer:
Upwards
Step-by-step explanation:
The general form of a quadratic is 
We can tell whether the curve opens upward or downward by the sign of "a"
If
- a is positive, the curve opens upward
- a is negative, the curve opens downward
Reaaranging the given equation:

Here, we see that a is positive, so the curve opens Upward
Answer:
a) 25%
b) 50%
c) 87.5%
Step-by-step explanation:
There are
number of outcome in total.
a)First and last flips come up heads. There are 4 outcomes here. Probability of the event is 4/16 = 1/4, or 25%.
- HHHH
- HHTH
- HTHH
- HTTH
b) at least 2 Consecutive flips that is heads. There are 8 outcomes. Probability of event is 8/16 = 1/2, or 50%
- HHHH
- HHHT
- HHTH
- HHTT
- THHH
- THHT
- HTHH
- TTHH
c) At least 2 consecutive flips that are the same. There are 14 outcomes. Probability of 14/16 = 7/8, or 87.5%
- HHHH
- HHHT
- HHTH
- HHTT
- THHH
- THHT
- HTHH
- TTHH
- TTTT
- TTTH
- TTHT
- HTTT
- HTTH
- THTT
Answer:
three basic methods of graphing linear functions.
The first is by plotting points and then drawing a line through the points.
The second is by using the y-intercept and slope.
The third is applying transformations to the identity function f(x)=x.
A midpoint divides a line segment into two congruent segments. So, if point U is the midpoint of RS, then that means that RU and SU are congruent.
If RU is 12, then SU is also 12.
So, the whole length of SR is 24.
1) Solution: 24
The midpoint and segment congruency statement in the first problem also applies to the second problem.
SV = TV
2x = 11
Divide both sides by 2 to get x by itself.
x = 5.5
2) Solution: 5.5
