Answer:
[-5, 10) or you can write [tex]-5\le x < 10[/tex]
Step-by-step explanation:
The domain is the set of all values of x used in the function. Scan across the graph from left to right (much as you do when reading). The first point you find on the graph has an x-coordinate 5 (see the solid dot?). Then, as you continue reading across the graph, there are values of x used until you get to 10. The dot at x = 10 is open, not filled in. That indicates that the number x = 10 is NOT used by the function.
So the domain is all real numbers greater than or equal to -5 and less than 10.
[-5, 10) is called interval notation; a square bracket means the value next to it IS used by the function, a parenthesis means the value next to it is NOT used.

Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to
Answers
Applying the Pythagorean theorem, we have ΔPQR ≅ ΔABC. then we would have: ∠ACB = ∠PRQ = 90°
What is the Pythagroean Theorem?The pythagorean theorem states that the square of the longest side (hypotenuse) of a right triangle is always equal to the sum of the squares of the other two sides (legs) of the right triangle.
Since we know that ΔPQR is a right triangle, then:
x² + y² = PQ²
We are also given that x² + y² = z², so by substitution, we have:
z² = PQ², which makes both triangles have corresponding congruent sides. Therefore, ΔPQR ≅ ΔABC.
Using the corresponding parts of the congruent triangles, we can conclude that: ∠ACB = ∠PRQ = 90°.

Step-by-step explanation:
Y=k/x
Y=2 & x=5 implies k=10
Hence, y=10/x is the desired equation of the hyperbola

Answer:
The equation is and y = 2 , x = 5 the value of k is 10 .
Step-by-step explanation:
As given
y varies inversely with x.
Where k is the constant of proportionality .
Thus the equation for the inverse variation .
As given
y = 2 when x = 5
Put all the values in the equation .
k = 2 × 5
k = 10
Thus the constant of variation is 10 .
Therefore the equation is and when y = 2 , x = 5 value of k is 10 .

Randall has a box that measures 12 inches × 9 inches × 8 inches. If Randy wants to cover the box with aluminum foil, how much foil will it take to cover the entire outside of the box?
Answers
Answer:
[tex]A=552\ inches^2[/tex]
Step-by-step explanation:
The dimensions of a box measures 12 inches × 9 inches × 8 inches.
We need to find the area of the aluminium required to cover the entire outside of the box.
We know that the surface area of the cuboidal box is given by :
[tex]A=2(lb+bh+bl)\\\\=2(12\times 9+9\times 8+8\times 12)\\\\=2\times 276\\\\=552\ inches^2[/tex]
So, the required area of the foil is equal to [tex]552\ inches^2[/tex].

The amplitude of the graphs of the sine and cosine functions is __
and the period of each is
__
Answers
The amplitude of the graphs of the sine and cosine functions is the vertical distance between the sinusoidal axis and the maximum or minimum value of the function.
And the period of each is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat.
The amplitude of each of the graphs of the sine and cosine functions is 1
The period of each of the graphs of the sine and cosine functions is 2π.
By definition, the amplitude of the graphs of the sine and cosine functions is defined as the vertical distance between the x - axis which is also called the sinusoidal axis and the peak value which is the maximum or minimum points located on the graph curve function. The basic graphs of sine and cosine function are the same and they have an amplitude equal to 1. By definition, the period of the graphs of the sine and cosine functions is defined as the the distance between two peaks of the graph or the period for which the graph repeats. In this case the time period is always 2π.Read more at; https://brainly.com/question/3919296
