Answer:
Yes it is a function. It passes the vertical line test. In other words, it is impossible to draw a single vertical line through more than one point on the V shaped graph. Any input leads to exactly one output.
The domain is the set of all real numbers. This is because we can plug in any x value leading to some specific y value. There are no holes or gaps or jumps to indicate we must restrict any given x value. The domain would not be the set of whole numbers only because values between the whole numbers (eg: decimal values like x = 2.75) work just fine.
The range is the set of y values such that y is either 0 or larger than 0. In short, the range is . Notice how any point on the V shaped graph has a y coordinate that is either 0 or larger than 0. It is impossible to get a y value that is negative.

The base of the pyramid is a square, with edges of 115 feet. The height of each lateral face is approximately 91.4 feet. How much glass was needed to construct the sides of the pyramid?
5,255.5 square feet
15,766.5 square feet
42,044 square feet
21,022 square feet
Check the picture below.
so each triangular face has a height of 91.4 and a base of 115, and there are four of them, now, we're only considering the "lateral area", that excludes the base.
[tex]\stackrel{\textit{area of 4 triangles}}{4\left[ \cfrac{1}{2}(115)(91.4) \right]}~~\implies ~~ 21022[/tex]

A hollow ball is made of rubber that is 2 centimeters thick. The ball has a radius to the outside surface of 6 centimeters. What is the approximate volume of rubber used to make the ball? Use 3. 14 for pi. 33. 5 cm³ 267. 9 cm³ 636. 4 cm³ 904. 3 cm³.
The volume of the ball is 636.38 cm^3. Option C shows the correct volume of the ball.
What is the volume of the sphere?The volume of the sphere is defined as the amount of space occupied within the sphere. It is a space occupied by a three-dimensional object.
Given that the thickness of the ball is 2 cm and the outer radius r2 of the ball is 6 cm. The inner radius r1 of the ball is the difference between the outer surface and the thickness of the material.
r1 = 6-2
r1 = 4cm
The volume of the sphere ball is given as,
[tex]V = \dfrac {4}{3}\pi r^3[/tex]
For the inner radius, the volume is given as,
[tex]V_1 = \dfrac {4}{3}\times 3.14\times (4)^3[/tex]
[tex]V_1 = 267.94 \;\rm cm^3[/tex]
For the outer radius, the volume is given as,
[tex]V_2= \dfrac {4}{3}\times 3.14\times (6)^3[/tex]
[tex]V_2 = 904.32\;\rm cm^3[/tex]
The final volume of the ball is the difference between the volume of the inner and outer surface.
[tex]V = V_2 - V_1[/tex]
[tex]V = 904.32- 267.94[/tex]
[tex]V = 636.38 \;\rm cm^3[/tex]
Hence we can conclude that the volume of the ball is 636.38 cm^3. Option C shows the correct volume of the ball.

What is the value of x?
Answer:
x = 5
Step-by-step explanation:
Set up proportion and cross multiply to solve:
9/2x-1 = 15/3x
x = 5
Answer:
Step-by-step explanation:
An angle bisector divides the base into ratios obtained by the sides of the triangle that are not divided. So
9/(2x - 1) = 15/3x Divide 3 into 15
9/(2x - 1) = 5/x Cross multiply
9x = 5(2x - 1) Remove the brackets
9x = 10x - 5 Switch sides.
10x - 5 = 9x Subtract 9x from both sides
10x - 9x - 5 = 0 Combine
x - 5 = 0 Add 5 to both sides.
x = 5

THIS AN ASTRONOMY QUESTION
Describe a general rule for how the angle that the parallels of declination make with the horizon are related to the latitude of the observer.
Answer:
The positions of your north celestial pole and south celestial pole change as you change latitude on the Earth, as you move north or south. At the Earth's equator, the Celestial Equator is directly overhead, and the poles are on opposite sides of the horizon. All stars are visible as they rise, culminate at the meridian, and set. As you move north, the Celestial Equator mirrors your movement, moving south the same number of degrees away from the zenith. The altitude of any star will change with the observer's latitude (as well as the time of night).
Note: only the altitude of the star changes NOT their coordinates. The star's celestial coordinates remain the same.
Step-by-step explanation:
Declination is measured in degrees north (+) or south (-) of an imaginary line called the Celestial Equator (CE). The Celestial Equator is the projection of the Earth's Equator onto the Celestial Sphere. The CE has a declination of 0 degrees, by definition. At dec = +90 degrees (90 degrees N) is the North Celestial Pole (NCP), the projection of the Earth's North Pole onto the Celestial Sphere. The South Celestial Pole (SCP) is at dec = -90 degrees.
An Example would be:
You move 30 degrees North of the equator, hence, the Celestial Equator has moved away from the zenith, 30 degrees to the south.
While the NCP has risen 30 degrees into the sky and the SCP has sunk 30 degrees below the horizon.
If you moved south, the opposite would have occurred as the Celestial Equator moved north of the zenith.

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Let, the number be = x
1) The value of __ divided by 32 is less that 1 that is :
x/32 < 1
x < 32
Any number less then 32 when divided by 32 will be less that 1.
2) The value of __ divided by 32 is equal to 1 that is :
x/32 = 1
x = 32
32 when divided by 32 will be equal to 1.
Therefore, the number will be :
1) Any number less then 32 when divided by 32 will be less that 1.
2) 32 when divided by 32 will be equal to 1.

Kari has been driving at a constant speed for the last hour. If Kari is traveling at a speed of 65 miles per hour, which equation best represents the relationship between time in hours, t, and distance in miles, d?
d = 65t
t = d + 65
t = 65d
d = t + 65
Answer:
(a) d=65t
Step-by-step explanation:
If, for example she drove 10 hours, and she drove 65 miles each hour:
d=?
