A line, called the line of reflection, will allow an image to reflect through it. Each point in an image is thought to reflect other figure when they are all equally spaced apart from one another.For the stated conditions.
The equation of the graph is given as-

Scott whose eye level is 1.5m above the ground, stands 30m from a tree. The angle of elevation of a bird at the top of the tree is 36 degrees. How far above the ground is the bird?
A. 21.8 m
B. 23.3 m
C. 41.3 m
Using trigonometric ratio, the distance of the bird is 21.8m
Angle of ElevationThe angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
To solve this problem, we have to use trigonometric ratio of SOHCAHTOA
Let's define the variables given;
Using Tangent of an angle;
tanθ = opposite / adjacent
tan 36 = x / 30
Cross multiply both sides and solve for x
30 tan36 = x
21.8 = x
The distance above the ground from the bird is 21.8 meter.

Solomon invested money in his bank account. He had a principal, P,
of $100 in his account at the beginning of the period, which
increased at a rate, r, of 0.15 per year. At the end of the period, he
had interest, I, of $135 in his account. Use the simple interest

earn this amount. (1 point)
h
O 9 months
O 108 months
O 233 months
900 months
The total time required in months is 108 months.
What is simple interest?
Simple interest is defined as the amount of interest paid on a specific principal, an amount at a specific interest rate. It is given by
I = Prt
where, I = simple interest, P = Principal, r = rate of interest, t = time taken
Given, P = $100
I = $135
r = 0.15
t = ?
So, simple interest is given by:
I = Prt
or, 135 = 100*0.15*t
or, 135 = 15*t
or, t = (135/15) = 9 years = 9*12 = 108 months
Hence, the total time required in months is 108 months.

The width of a rectangle is 4 more than the length. If the perimeter is 36 cm, ind the dimensions (length and width) of the rectangle.
Answer with step-by-step explanation:
Let the width of the rectangle be x.
Given that,
length ⇒ 4
width ⇒ x + 4 ( Because, the rectangle's width is 4 more than the length.)
Perimeter ⇒ 36cm
The formula to find the perimeter of rectangle is:
P = 2 ( l + w )
Now to find the value of x replace P, l & w with 36, 4 & (x + 4) with respectively.
P = 2 ( l + w )
36 = 2 ( 4 + x + 4 )
36 = 2 ( x + 8 )
Solve the brackets.
36 = 2x + 16
Substract 16 from both sides.
36 - 16 = 2x
20 = 2x
Divide both sides by 2.
10 = x
And now let us find the exact dimensions of the rectangle.
Length = 4 cm
Width = x + 4 = 10 + 4 = 14 cm
Does the graph below represent a function
A. Yes
B. No
C. Sometimes
D. Not enough information
Answer:
Step-by-step explanation:
Yes, it is a function.
The reason for this is because it passes what is called the Vertical Line Test, notice how if you draw a completely straight line down, it will only make contact with the graph one time. It is hard to tell, but even though it looks like the graph stops at x=±3, the graph is actually approaching the values ever so slightly, therefore maintaining the conditions for the vertical line test.
The answer is A. Yes.

a. How many cubes with an edge length of b. What is the volume, in cubic inches, of inch are needed to build a cube with one cube with an edge length of inch? an edge length of 1 inch?
The number of cubes of edge length 1/3 is 27 and the volume of the cube is 1 cubic inches
How to determine the number of cubesFrom the question, we have the following parameters that can be used in our computation:
Edge length of cube 1 = 1/3 inchEdge length of cube 2 = 1 inchThe volume of a cube is the cube of its edge length
This means that the volumes are
Volume = Edge length³
So, we have
Volume of cube 1 = (1/3 inch)³ = 1/27 cubic inches
Volume of cube 2 = (1 inch)³ = 1 cubic inch
The number of cubes is then calculated as
Number of cubes = Volume of cube 2/Volume of cube 1
This gives
Number of cubes = 1/(1/27)
Number of cubes = 27
The volume of the cubesHere, we have
Edge length of cube = 1 inch
The volume of a cube is the cube of its edge length
This means that the volumes are
Volume = Edge length³
So, we have
Volume of cube = (1 inch)³ = 1 cubic inch

In Silvergrove, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 kilometers and the distance between the courthouse and the city pool is 10 kilometers, how far is the library from the community pool? If necessary, round to the nearest tenth.
The distance of the library from the community pool is given as 4.4 km
How to solve for the distanceWe have to solve this problem with the use of the Pythagoras theorem.
The formula is given as
a² = b² + c²
The total distance flown would be represented by a = 10 kilometer
the distance for the courthouse would be given as 9 kilometers
When we put these values in the formula we would have
10² = a² + 9²
100 = a² + 81
a² = 100 - 81
a² = 19
a = √19
a = 4.4 km
Hence the calculated distance is given a 4.4 km from the library to pool.

The half-life of a drug in the bloodstream is 14 hours. What fraction of the original drug dose remains in 36 hours? in 72 hours?
What fraction of the original drug dose remains in 36 hours?
(Do not round until the final answer. Then round to the nearest hundredth as needed.)
16.82 % and 2.83% of the original drug dose remain in 36 hours and 72 hours respectively.
What is half-life?
Half-life is a characteristic unit for the exponential decay equation and is constant across the lifespan of an exponentially decaying quantity.
Given, the half-life of a drug(h) = 14 hours
The first condition, time duration (t) = 36 hours
Then, the half-life of the substance can be calculated by:
[tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]
or, [tex]A = A_{0} * (1/2)^{\frac{36}{14} }\\A = A_{0} * (0.1682)\\[/tex]
16.82 % of the original drug dose remains in 36 hours
Hence, 16.82 % of the original drug dose remains in 36 hours
The second condition, time duration (t) = 72 hours
Then, the half-life of the substance can be calculated by:
[tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]
[tex]A = A_{0} * (1/2)^{\frac{72}{14} }\\A = A_{0} * (0.0283)\\[/tex]
2.83 % of the original drug dose remains in 72 hours
Hence, 2.83 % of the original drug dose remains in 72 hours

Write an equation for (-5,3) and (0,-7)
The equation of line is y + 2x +7 =0 for the points (-5,3) and (0,-7).
What is equation of line?A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.
The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.
The given points are (-5, 3) and (0, -7).
To find the equation of line, use formula,
y - y₁ = m(x - x₁) where m = (y₂-y₁)/(x₂-x₁),
y - 3 = (-7 - 3)/(0-(-5)) (x - (-5))
y - 3 = -10 / 5 (x + 5)
y - 3 = -2 (x + 5)
y + 2x +7 =0

Think About the Process You have 30 quarters. You find 20% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping. Calculate, in dollars, the amount of money you have left.
Answer: $4.5 left.
Step-by-step explanation:
You have 30 quarters, and find 20% more. To convert percentages to decimals for calculations, simply move the decimal two spaces to the left.
20% is 20. ---> 2.0 ---> .20
30 * 0.2 = 6. Now add 6 (found) to 30 (original) to get the total.
30+6 = 36 total quarters.
You spend 50% of the quarters, 36 * 0.5 = 18.
This means you have 18 quarters left (or you spent 18).
18 quarters, each quarter is worth 0.25 dollars, so multiply the number left by how much each is worth.
18 * 0.25 = $4.5.
$4.50 is the amount left

What is a function?A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).
if f(x) = 2x, then f(x-4) = 2(x-4)
g(x) = f(x-4) + 5
substitute f(x-4) into g(x)
g(x) = 2(x-4) + 5
g(x) = 2x -8 + 5
g(x) = 2x - 3
