Answer:
√39
Step-by-step explanation:
An irrational number is a number that cannot be expressed by a fraction.
√9 = 3
√49 = 7
All whole numbers can be expressed as fractions and are <u>not</u> irrational numbers.
1.7 = 17/10 which is <u>not</u> an irrational number.
Answer:
Centre (0,0)
Radius √9 = 3
I've attached a graph if the circle with it

Answer:
Using the point (-2,-4) it would be:
y + 4 = 1/3(x + 2)
Using the point (4,-2) it would be:
y + 2 = 1/2 (x - 4)
Step-by-step explanation:
hope this helps :)
Answer:
please what should we found? is it the value of ×or y
The function represents a <em>cosine</em> graph with axis at y = - 1, period of 6, and amplitude of 2.5.
<h3>How to analyze sinusoidal functions</h3>
In this question we have a <em>sinusoidal</em> function, of which we are supposed to find the following variables based on given picture:
- Equation of the axis - Horizontal that represents the mean of the bounds of the function.
- Period - Horizontal distance needed between two maxima or two minima.
- Amplitude - Mean of the difference of the bounds of the function.
- Type of sinusoidal function - The function represents either a sine or a cosine if and only if trigonometric function is continuous and bounded between - 1 and 1.
Then, we have the following results:
- Equation of the axis: y = - 1
- Period: 6
- Amplitude: 2.5
- The graph may be represented by a cosine with no <em>angular</em> phase and a sine with <em>angular</em> phase, based on the following trigonometric expression:
cos θ = sin (θ + π/2)
