A conjecture is a statement that you believe to be true, and that has be verified by your observations, not necessarily exhaustively. That is to say, your conjecture may not even be true, although you believe that it is.
If we denote by S the sum of the first 30 positive even numbers, we could make many conjectures, such as:
S is even
S is positive,
S=930
S is composite
.... etc.
Answer:
x = ±2√10
Step-by-step explanation:
40 - x² = 0
⇌
(√40 - x)(√40 + x) = 0
⇌
x = √40 or x = -√40
we can go further and say that √40 = 2√10
Hi there!
If you run into problems like this, remember to "Stay calm and find the common denom." That just means find the common denominator.
13/35 and 2/5 = 13/35 and 14/35
As you can tell, 2/5 is larger.
Hope this helps.
:)

divisible by 2 because the last digit is divisible by 2
NOT divisible by 3 because the sum of its digit (22) is not a multiple of 3
divisible by 4 because the last 2 digits (68) are divisible by 4
NOT divisible by 5 because the last digit (8) is neither 0 nor 5
NOT divisible by 6 (to be divisible y 6, it should be divisible by 2 and 3)
divisible by82 because the last 3 digits (168) ae divisible by 8
NOT divisible by 9 because the sum of its digit (22) is not a multiple of 9
NOT divisible by 10 because the last digit (8) is not 0
Having written the rules, you can easily apply them to solve the last 2 exercices.
The midline, amplitude and period respectively of the given sine graph are; x = 1; 2; π
<h3>Midline, Amplitude and Period</h3>
The midline of this trigonometric graph is defined as the horizontal line that divides the maximum and minimum point distance into two equal parts. In this case, the midline is x = 1
The amplitude of a graphed function is usually the peak of the wave of that graph. In this case, we see that the peak of the graph is at y = 4. Thus, Amplitude = 4
Period is the difference between two consecutive maximum or minimum points. In this graph, the period is π
