What is the length of AB.
Answers
To find the length of AB in triangle ABC with , apply the Law of Sines. Solving for x, we find x = 3. Substituting this into AB = 4x, the length of AB is 12 units, corresponding to answer (d).
To find the length of AB, we can use the Law of Sines in triangle ABC:
Substitute the given values:
Cancel out from both sides:
4x = 2x + 6
Subtract 2x from both sides:
2x = 6
Divide by 2:
x = 3
Now, substitute x = 3 back into AB = 4x:
So, the correct answer is (d) 12.
Applying the Law of Sines to triangle ABC with angles , we find x = 3. Substituting into AB = 4x, the length of AB is 12 units. The Law of Sines relates the lengths of sides in a triangle with the sine of their opposite angles, enabling the determination of AB as 12 units (option d).

3.5 belongs to Rational number sets mainly and also belongs to Real Numbers.
Step-by-step explanation:
Number Sets are nothing but group of number classified into groups.
They are Natural, Whole, Integers, Rational, Irrational and Real numbers.
Natural number set = {1,2,3...},
Whole number set= {0,1,2,3...},
Integers = { ....-2, -1, 0, 1, 2, ....},
Rational numbers = { Integers, Decimals, Fractions},
Irrational numbers = { non fractional numbers eg: π, etc.}
Real = { Natural, Whole, Integers, Rational, Irrational }.
Any number which is a fraction resulting in a decimal value is Rational Number sets.
3.5 is a decimal number so it can be Rational Number sets also Real Number sets.

250 miles is equivalent to 400 kilometers.
We have,
To find out how many kilometers are equivalent to 250 miles, we can set up a proportion using the given information that 5 miles are equal to 8 kilometers.
5 miles : 8 kilometers
We can set up the proportion:
5 miles / 8 kilometers = 250 miles / x kilometers
To solve for x (the number of kilometers in 250 miles), we can cross-multiply and then divide:
5 miles x (x kilometers) = 8 kilometers x 250 miles
5x = 2000
Dividing both sides by 5:
x = 400
Therefore,
250 miles is equivalent to 400 kilometers.

From the other answer, I see that my colleague with the busted clock
interpreted your question in a different way. So I should explain
how I understand your question.
I understand you to say that both English sections meet at the
same time, all 3 math sections meet at the same time, all 3 History
sections meet at the same time, and all 4 Biology sections meet at
the same time. So our student will take the subjects in that order,
but for each period, she can choose which section to join.
If that's not the right way to understand the question, then it's definitely
too complicated for me.
Reading it MY way,
here's the solution:
English: 2 choices. For each of those . . .
Math: 3 choices. For each of those . . .
History: 3 choices. For each of those . . .
Biology: 4 choices.

Answer:
Second graph
Step-by-step explanation:
The second graph is the correct one. Why? because the y intercept is (0, 3), and also because the base, 1/5, is between 0 and 1, which leads to a decaying exponential graph.
