Answer: Memorize the formula
Step-by-step explanation:
( x / a )^2 - ( y / b )^2 = 1
Where a and b are the semi-axis
The value of a is half the distance from points that cuts off x-axis, in this case
From -5 to 5 there is 10 so 5 is value of "a"
Value of b can find by the formula
c^2 = a^2 + b^2
Which c is the value of the point bold on the rightmost place in x axis. In this case its 13
13^2 = 5^2 + b^2
169 = 25 + b^2
b = 12
SO we got a = 5, b = 12
ANSWER: (x/5)^2 - (y/12)^2 = 1

Of the last 18 trains to pull into Castroville Station, 12 were full. Considering this data, how many of the next 12 trains would you expect to be full?
Answers
Answer:8
Step-by-step explanation:
There are 12 of the next 12 trains would expect to be full.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Based on the information provided, it seems that 12 out of the last 18 trains to pull into Castroville Station were full, which is a proportion of 12/18 or 2/3.
Therefore, if the same proportion of full trains holds in the future, one would expect 2/3 or 8 of the next 12 trains to be full.
This prediction is based on the assumption that the proportion of full trains remains constant.
Thus, there are 12 of the next 12 trains would expect to be full.

A curve is given the equation xy=25 and the equation of a line y=mx+b.
i. Express m in terms of b given that the line and the curve have one and only one point of intersection.
ii. If the line intersects the curve in two distinct points, find the set of values of b, given m=-5
Answers
Answer:
Below in bold.
Step-by-step explanation:
i, This is a rectangular hyperbola with symmetry about the line y = -x
If it touches the graph at one point only then
y = 25/x
y = mx + b so
25/x = mx + b
mx^2 + bx + 25 = 0
Using the quadratic formula:
x = (-b + sqrt(b^2 - 25*4*m)) / 2m
Now there's only one value of x so
b^2 - 25*4*m = 0
b^2 = 100m
m = b^2/100.
m = +/-b/10.
ii In this case b^2 > 100m
If m = |-5|
b^2 > 500
b > +/-√500
So b > √500 or b < -√500.

Jennifer writes the letters M-O-N-T-A-N-A on cards and then places the cards in a hat. What is

Answers
Given:
Jennifer writes the letters M-O-N-T-A-N-A on cards.
To find:
The probability of picking an N.
Solution:
We have,
Total number of cards = 7
Total number of cards with letter N = 2
Now, the probability of picking an N is:
[tex]\text{Probability}=\dfrac{\text{Number of cards with letter N}}{\text{Total number of cards}}[/tex]
[tex]\text{Probability}=\dfrac{2}{7}[/tex]
Therefore, the probability of picking an N is [tex]\dfrac{2}{7}[/tex].

Answer:
a = 2, b = 3
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , so
3a + 11 = a + 15 ( subtract a from both sides )
2a + 11 = 15 ( subtract 11 from both sides )
2a = 4 ( divide both sides by 2 )
a = 2
and
3b + 5 = b + 11 ( subtract b from both sides )
2b + 5 = 11 ( subtract 5 from both sides )
2b = 6 ( divide both sides by 2 )
b = 3
