Answer:
Step-by-step explanation:
There are a couple of relations that are applicable to these questions.
- the product of segment lengths of crossed chords is the same for both chords
- the angle formed at crossed chords is the average of the intercepted arc measures
__
The segment lengths relation tells us ...
10x = 8×7 . . . . . . products of segment lengths are equal
x = 56/10 = 5.6 . . . . divide by 10
__
The value of y° is the average of the intercepted arcs:
y° = (85° +45°)/2 = 65°
_____
<em>Additional comment</em>
This diagram does not have enough information to allow computation of z. We would need to know the intercepted arc, or the length of the secant that meets tangent z.
Answer:
y = 1/3 x + 2
Step-by-step explanation:
We see points (-3, 1) and (3, 3).
We also see point (0, 2), the y-intercept.
To go from (-3, 1) to (3, 3), go up 2 and right 6.
slope = m = rise/run = 2/6 = 1/3
y = mx + b
y = 1/3 x + 2
Answer:
The first term is:
Step-by-step explanation:
The arithmetic sequence is defined by
where
is the first term
is the common difference
as
the 17th term of an arithmetic sequence is 51.
i.e. 
so
∵ 
, , 
∵ 
Therefore, the first term is:
Answer:

Step-by-step explanation:
Answer:
3/4×7
= 0.75×7
=5.25
7×3/4
=7×0.75
=5.25
3×7/4
=3×1.75
=5.25
all answer is same so, however we do all answer come 5.25
this way they all are related
