Answer:
D.
Step-by-step explanation:
we are given
we can use standard equation of hyperbola
where
center=(h,k)
center at origin
so, h=0 and k=0
vertex is
we can use formula
vertices: (h, k + a)
we get
we can plug k=0
now, we can plug these values
now, we are given it passes through
so, we have
we can plug these values and then we can solve for b
and we get
we can solve for b
and we get
now, we can plug these values
we can simplify it
and we get
Answer:
vvvvvvvvvvvvvvvvvvvvvv is equal to 65654
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
quadratic formula: -b±√b²-4ac/ 2a
a= -10
b= 12
c= -9
-12±√144- 4(-10)(-9)/ 2(-10)
-12±√144- 360/ -20
-12±√-216/-20
6±3i√6/ 10
simplify: 3/5± 3i√6/10
Answer:
The answer to your question is: letter D
Step-by-step explanation:
The interval graph is (5, 9] , open five, nine close. As an inequality this interval is:
5 < x ≤ 9
a) Letter A is incorrect because it suggests that two sections in the graph must be shaded and in this graph there is only one section shaded.
b) Letter B is incorrect because in the graph we observe that before 5 there must be a parenthesis because the point is open and the point in 9 is shaded so it must be follow by a ].
c) Letter c is alos incorrect because it suggests two sections shaded in the graph and it shows only one.
The Answer of the question is "B" or 1,600
