Find the angle of depression
from point A to point C.

5 mi
B
O
Angle of depression = [ ? jº
Enter
Answer:
Step-by-step explanation:
From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.

Find the area of a right triangle whose hypotenuse is 20 units long and the altitude drawn from the Right angle divides the hypotenuse into 5 units and 15 units.
Step-by-step explanation:
the height of the triangle = √(5×15)= √75
=5√3 units
the base of triangle= 20 units
so, the area = ½×20×5√3= 50√3 units
or 86.60 units

Which of the following is a perfect square trinomial?
Answer:
A.
Step-by-step explanation:
Take a look at what happens when squaring either of these...
[tex](ax-by)^2=(ax-by)(ax-by)=a^2x^2-2abxy+b^2y^2\\\\(ax+by)^2=(ax+by)(ax+by)=a^2x^2+2abxy+b^2y^2\\[/tex]
Notice a couple of patterns.
1. The last term has a positive coefficient. That rules out answer choices C and D.
2. The coefficient of the middle term is either [tex]+2ab \text{ or } -2ab[/tex] . So what are a and b? a is the square root of the x^2 term and b is the square root of the y^2 term.
[tex]25x^2 \Rightarrow a=5\\\\9y^2 \Rightarrow b=3\\\\ab=15\\\\2ab=30[/tex]
The middle coefficient needs to be either +30 or -30. The answer is choice A.
i have a geometry question.
Answer:
Step-by-step explanation:
You already have the area for your triangle. Substract that from the entire area of the rectangle.
To get the area of the rectangle, multiply the length by the height.
15*20 = 300
Now substract your triangle from that :)
what times twelve is exactly 30
the answer is most likely a mixed number
Answer:
2.5 or 2 and 1/2
Step-by-step explanation:
30/12 = 2.5
There are two wholes that fit in 30 with a remainder of half of a whole.
2.5 translates to 2 and 1/2
Answer:
Hello! answer: 2½
Step-by-step explanation:
Assuming you mean mixed number as in fraction I did 30 ÷ 12 = 2.5 and converted it to a mixed number and since 2½ × 12 = 30 the answer is 2½ Hope that helps!
Which of these could be the graph of F(x) = log2 x?
A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answer: it’s A
Step-by-step explanation:
I just took the test
The graph of f(x) is shown by figure A.
We have given that the function,
[tex]f(x)=log_2x[/tex]
We have to determine the graph ofthe given function
We have to find the co-ordinate of the given finction
What is the method for finding the coordinate?We have to put one variable value that is any real number and by using this value find the value of another variable.
[tex]y=f(x)=log_2x[/tex]
[tex]y=log_2x[/tex]
Put x=1
[tex]y=log_2(1)\\y=0[/tex]
We get the point A(1,0)
put x=2
[tex]y=log_2(2)\\y=1[/tex]
We get the point B(2,1)
Put x=4
[tex]y=log_2(4)\\y=2[/tex]
We get the point C(4,2)
So we plot this point on coordinate system so we get the graph
as shown below
Therefore the option A is correct.

Ana can bike 9 kilometers in 24 minutes. At this rate, how far can Ana bike in 1 minute? __ kilometer(s) per minute
Answer: 9/24km
Step-by-step explanation:
Since we are informed that Ana can bike 9 kilometers in 24 minutes.
To calculate the distance that Ana can bike in 1 minute will be gotten by dividing the distance covered divided by the time taken. This will be:
= 9/24 km
Therefore, Anna can bike 9/24km in 1 minute.

Using the graph, determine the coordinates of the roots of the parabola.
Answer:
(7, 0) and (3,0)
Step-by-step explanation:
On the graph, the parabola crosses the x-axis at two points. The two points are called the roots. And since they cross at (7, 0) and (3, 0), they are our roots. Hope this helps!
Answer:
-7 and -3
Step-by-step explanation:
Hello!
The roots of a parabola are the points at which the graph intersects the x-axis. The x-axis is located at y = 0.
As you can see, the graph's vertex is below the x-axis and opens upwards. This means the graph has 2 roots.
The points of intersection are:
(-7,0)(-3,0)The roots of the parabola are -7 and -3.
A cylinder is shown. Which could be the base shape of the cylinder? line non-square rectangle circle square
Answer: I believe the correct answer from the choices listed above is the third option. The base shape of a cylinder would be circle. A cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface.
Hope this answers the question. Have a nice day.
The base shape of the cylinder is a circle, the correct option is D.
What is a Cylinder?A cylinder is a three dimensional figure made up of parallel circular discs.
The best shape of the base of a cylinder can be a circle only.
The cylinder has two circular bases as the surface joining the two bases is curved and has the same radius as the base.

Colton has a stone paperweight composed of a triangular pyramid on top of a triangular
prism with the dimensions shown below. Use the drop-down menus to explain how to
determine the volume of the paperweight.
Answer:
1/2 * 5 * 5
4
1/3, 7
79 in³
Step-by-step explanation:
The area of the base : base is shaped like a triangle ;
Area of triangle = 1/2 base * height :
Base and height = 5
Area of base = 1/2 * 5 * 5 = 12.5 in²
Volume of triangular prism = Area of base * height
Volume of triangular prism = 12.5 * 4 = 50 in³
For the triangular pyramid :
Area of base * height of pyramid *1/3
12.5 * 7 * (1/3) = 29.17
The volume of the paperweight :
Volume of triangular pyramid + volume of triangular prism
29.17 + 50
79.17 = 79 in³
