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
Answer:
no, it’s not correct
Step-by-step explanation:
I just know, it would be the second one
Because 1/2 ≠ 1/6.
We know that 1/6 < 1/2, so we can set up an equation to see how many copies are needed for them to be equal.
(1/6)x = 1/2
[(1/6)x] × 6 = [1/2] × 6
x = 6/2 = 3
This equation shows that 1/6 × 3 = 1/2, therefore we need 3 copies of 1/6 to equal 1 copy of 1/2.

Answer:
Step-by-step explanation:
You would never buy a 10-pack, because two 5-packs cost less.
To buy 3 bars you need a single bar and a pair of single bars for £0.82 + £0.82+ £0.41 = £2.05
To buy 30 bars you need 3 pairs of 5-bar packs = 3×£5.75 = £17.25
To buy the remaining 5 bars you need one 5-bar pack = £3
cost = £2.05 + £17.25 + £3 = £22.30
