A) 32 signifies the hourly rate, and 42 signifies the overhead charge
B) 42 signifies the hourly rate, and 32 signifies the overhead charge
C) 74 signifies the cost for an on-site inspection
D) -42 signifies the hourly rate, and 32 signifies the travel cost
Answer:
B) 42 signifies the hourly rate, and 32 signifies the overhead charge
Step-by-step explanation:
The hourly rate is the amount of money given per hour worked. 42x basically means that for every hour, $42 are given.
As for 32, it is the overhead charge, which isn't paid every hour but rather only once. That is why it has no variable beside it.

Answer:
The answer is option 3.
Step-by-step explanation:
First we have to find the area of both rectangle and triangle :
Rectangle,
[tex]area = base \times height[/tex]
Let base = 9,
Let height = 3,
[tex]area = 9 \times 3 \\ area = 27 \: {m}^{2} [/tex]
Triangle,
[tex]area = \frac{1}{2} \times base \times height[/tex]
Let base = 3,
Let height = 3,
[tex]area = \frac{1}{2} \times 3 \times 3 \\ area = \frac{1}{2} \times 9 \\ area = \frac{9}{2} \\ area = 4.5 \: {m}^{2} [/tex]
Lastly, in order to find the shaded region you have to substract the area of triangle from the area of rectangle :
[tex]area = 27 - 4.5 \\ area = 22.5 \: {m}^{2} [/tex]
Answer:
its 22.5 because i did a sguare then divivded it by 2 then i added the rectangle

5 cm
The required length of the diagonal AB would be 8.66 cm.
What is the formula for the length of the diagonal of a cube?The formula for the length of the diagonal of a cube follows as
d = √ (L² + W² + H² )
Where H is the height of the cube, W is the width of the cube and L is the length of the cube
We have been that the dimensions of a cube are as:
The length of the cube (L) = 5 cm
The height of the cube (H) = 5 cm
The width of the cube (W) = 5 cm
d = √ (L² + W² + H² )
d = √ (5² + 5² + 5² )
d = √ (25 + 25 + 25 )
d = √75
d = 8.66
Therefore, the required length of the diagonal AB would be 8.66 cm.

Part A
Could the baton lie flat on a diagonal along the base of the box?
A. Yes, because the diagonal is 48 inches long.
B. Yes, because the diagonal is 41.4 inches long.
C. No, because the diagonal is 37.3 inches long.
D. No, because the diagonal is 18.4 inches long.
I think C. but need help, is it right? How so?
Part B
Could the baton fit along the interior diagonal of the box? Explain.
Answer:
C.; Yes
Step-by-step explanation:
A)
The longest thing that can fit along the base of the box is sqrt ( 13^2 + 35^2) = 37.3, which is less than 38, so NO, the baton can't lay flat on a diagonal along the base of the box C. No, because the diagonal is 37.3 inches long.
B) The interior diagonal of the box is sqrt(13^2 + 13^2 + 35^2) = sqrt (1563), which is 39.5, which is greater than 38, so YES, the baton can fit along the interior diagonal of the box.
A regular hexagon is rotated about its center. Which degree measure will carry the regular hexagon onto itself ?
Final answer:
A regular hexagon will coincide with itself when rotated by angles of 60 degrees, or multiples of it like 120, 180, 240, 300, and 360 degrees, because these are the angles of rotational symmetry for a hexagon.
Explanation:
A regular hexagon has six sides of equal length and interior angles that are also equal. When a regular hexagon is rotated about its center, there are specific degree measures for which it will fit exactly onto itself, known as the angles of rotational symmetry. Since a full rotation measures 360 degrees and a hexagon has six sides, we can divide 360 degrees by the number of sides to find the smallest angle of rotation that will carry the regular hexagon onto itself.
The calculation is 360 ÷ 6 = 60 degrees. Therefore, a regular hexagon will coincide with itself every 60-degree turn. Other angles that will carry the hexagon onto itself are multiples of 60 degrees: 120 degrees, 180 degrees, 240 degrees, 300 degrees, and 360 degrees (a full rotation).

Which function is equivalent to y = 3(x + 2)2 + 7?
A y = 3x2 + 12x + 33
B y = 3x2 + 12x + 19
C y = 3x2 + 19
D y = 3x² + 33
Answer:
B y = 3x^2 + 12x + 19
Step-by-step explanation:
y = 3(x + 2)^2 + 7
To expand the square of the binomial,
either recall that (a + b)^2 = a^2 + 2ab + b^2, or use FOIL.
y = 3(x^2 + 4x + 4) + 7
y = 3x^2 + 12x + 12 + 7
y = 3x^2 + 12x + 19
Answer: B y = 3x^2 + 12x + 19
Final answer:
After expanding and simplifying the given function, we find that the equivalent function is y = 3x^2 + 12x + 19, which corresponds to option B.
Explanation:
The task is to find the equivalent function to y = 3(x + 2)2 + 7. We'll start by expanding the square and then distributing the 3 across the resultant terms.
First, expand the square: (x + 2)2 = x2 + 4x + 4.
Next, distribute the 3: 3(x2 + 4x + 4) = 3x2 + 12x + 12.
Finally, add the 7 to complete the expansion: 3x2 + 12x + 12 + 7 = 3x2 + 12x + 19.
Therefore, the equivalent function is B y = 3x2 + 12x + 19.

Step-by-step explanation:
5. sin 31 = opp/ hyp
sin 31 = 34 /x
x = 34 / sin 31
x =66.0145369
tan 31 = opp /adj
tan 31 = 34/y
y = 34/ tan 31
y= 56.5855024
6. Pythagorean theorem to find z
9^2+12^2 = z^2
81+144 = z^2
225 = z^2
z =sqrt(225) =15
sin x = opp / hyp
sin x = 9/15
take the inverse sin
x = sin^ -1 (9/15) = 36.86989765
sin y = opp / hyp
sin y = 12/15
take the inverse sin
y = sin^ -1 (12/15) = 53.13010235
Answer:
1. sin(31) = opposite/hypotenuse
sin(31) = 34/x
x = 34/sin(31) = 66.0145369
x = 66.0°
tan(31) = opposite/adjacent
tan(31) = 34/y
y = 34/tan(31) = 56.5855024
y = 56.6°
2. tan(x) = opposite/adjacent
tan(x) = 9/12
x = 36.86989765
x = 36.9°
y = 180 - 90 - x
y = 53.13010235

9. A person stands at the window of a building so that his eyes are 12.6 m above the level ground. An
object is on the ground 58.5 m away from the building on a line directly beneath the person. Compute
the angle of depression of the person's line of sight to the object on the ground.
Answer:
[tex]\theta = 12.16^0.[/tex]
Step-by-step explanation:
Given,
Height = 12.6 m
Object distance from the person = 58.5 m
Angle of depression
[tex]tan \theta = \dfrac{P}{B}[/tex]
[tex]tan \theta = \dfrac{12.6}{58.5}[/tex]
[tex]tan \theta = 0.2154[/tex]
[tex]\theta = 12.16^0[/tex]
Hence, angle of depression is equal to [tex]\theta = 12.16^0.[/tex]
The angle of depression of the person's line of sight to the object on the ground is 12.15°.
The information forms a right angle triangle. The person eyes above the ground is the opposite side of the triangle. The object distance from the building in line of the sight is the adjacent side of the right angle triangle.
Therefore,
using trigonometric ratio,
tan Ф = opposite /adjacent
tan Ф = 12.6 / 58.5
tan Ф = 0.21538461538
Ф = tan⁻¹ 0.21538461538
Ф = 12.1549416972
Ф = 12.15°
