5 days food for 150 students suggests there was 750 day rations
If there was 100 students this would last 750/100 = 7.5 days.
If it ran out after 4 days there were 750/4 = 187 students (187.5 not valid)
Answer:
Option A
Step-by-step explanation:
Sin(x) is the same value as cos(y) in the graph.
There's a property of logs I want you to remember, that is:
log(a)ᵇ = b*log(a)
We'll be using this property to solve the question
<u>Finding x:</u>
log(2)ˣ = log(3)
x*log(2) = log(3) [using the property mentioned above]
x = log(3) / log(2) [dividing both sides by log(2)]
Hence, the correct answer is option E.
Answer: 4x-1
Step-by-step explanation:

The discriminant is the portion of the quadratic formula under the root sign: b²-4ac
A quadratic equation in standard form is ax²+bx+c=0. In your equation:
a=1, b=2, and c=6. Substituting them into the equation:
2²-4(1)(6)
=4-24
=(-20)
When the discriminant is negative there are two, imaginary solutions.
If the discriminant equals a positive, perfect square number (like 4, 9, 16, etc), there will be two, rational roots.
If the discriminant equals a positive, nonperfect square number (like 3, 15, 23, etc), there will be two, irrational roots.
If the discriminant equals 0, there will be one double root
A quadratic equation graphs a parabola. The graph of a quadratic with a positive discriminant will pass through the x-axis twice. If the discriminant is 0, it will touch the x-axis and 'bounce' back the way it came. If the discriminant is negative, it will not touch the x-axis.
