Answer:
the equation of the hyperbola is;(x²/81) - (y²/1600) = 1
Step-by-step explanation:
We are given that the hyperbola has;
Centre; 0,0
Vertex; 9,0
Focus; 41,0
Thus,the vertex and focus are on the x-axis. Thus, the equation for the hyperbola will have the form;
(x²/a²) - (y²/b²) = 1
Since The vertex is (9,0),so
a = 9 and a² = 9² = 81
Also,Since The focus is (41,0),so
c = 41 and c² = 41² = 1681
Solving for b², we have;
b² = c² - a²
b² = 1681 - 81
b² = 1600
b = √1600
b = 40
Thus,equation of hyperbola is;
(x²/9²) - (y²/40²) = 1
Which gives;
(x²/81) - (y²/1600) = 1
The product of 5 x 2 is 10, this is the same as adding 2 to 2 5 times brainliest pls
Answer:
The two triangles are related by SAS, so the triangles are congruent.
Step-by-step explanation:
We can see that both of them have 2 similar sides, and 1 similar angle. This goes underneath the rule SAS, which makes the triangle congruent

Answer:
7
Step-by-step explanation:
(a^3 - b^3) / 5
Let a=2 and b = -3
Do the exponents inside the parentheses
(2^3 - (-3)^3) / 5
Then add
(8 - (-27))/5
Subtracting a negative is like adding
(8+27)/5
( 35)/5

Answer:
h = 196/65
Step-by-step explanation:
65 miles /1 hour is the moving rate
200 miles is the distance to the railroad maker
h = ?
200- 4 miles = 196 miles were left behind the train
65miles /1 hour , 130miles/2hours , ..196miles/ ?hours
h = 196/65 = 3 hours and 1/65 minutes from an hour = 3 hours and 12/13 min.
60/ 65 = 12/13
