Answer:
d. -9 ≤ y ≤ 5
Step-by-step explanation:
The range is the vertical extent of the graph. This graph goes from a low of -9 to a high of +5. Then the range is ...
-9 ≤ y ≤ 5
Answer:
16x^2 - 49y^2 = 784
Step-by-step explanation:
as we know that this is the standard equation of hyperbola bcz 1 coordinate of vertices is 0.
since in vertices x coordinate is present and y coordinate is 0 so Tranverse axis of hyperbola is along x axis .
vertices in general = (a,0) and (-a,0)
vertices given = ( 7,0) and (-7 , 0)
so a=7
similarly
co vertices in general = ( 0 , b) and ( 0 , -b)
co vertices given = ( 0, 4) and (0 , -4)
so,
b= 4
now equation for x axis is:
(x2/a2) - ( y2/b2) = 1
by putting values we observe the ans is
16x^2 - 49y^2 = 784
The answer is d 41 X 12= 492
Step-by-step explanation:
12 (12 + 17)
12(41)
= 492
