The right triangle with sides 29m, 49.5m and 57.4 m has the value of cot φ as 1.707
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees.
Therefore, it has an opposite, adjacent and hypotenuse side depending on the angle.
oposite side = 29 m
adjacent side = 49.5 m
hypotenuse side = 57.4 m
Therefore,
cot φ = 1 / tan φ
Hence,
tan φ = opposite / adjacent
Therefore,
cot φ = adjacent / opposite
cot φ = 49.5 / 29
cot φ = 1.70689655172
cot φ = 1.707

Answer:
g(-2) = -1
Step-by-step explanation:
By looking at the graph, we can see that g(-2) where x = -2 is represented. Because x = -2, we can see that the y-value that correlates to this x-value is -1.
So g(-2) = -1.

Which statements describe the graph of y = 4x2 28x 49? check all that apply. the graph has two x-intercepts because 4x2 28x 49 has two different factors. the equation 2x 7 = 0 can be used to find a zero of the function. the equation (2x – 7)2 = 0 can be used to find the y-intercept. the graph has a double root at x = startfraction negative 7 over 2 endfraction. the graph intersects the y-axis at y = 49.
The true statements about the graph y = 4x2 + 28x + 49 are as follows;
(b) The equation 2x + 7 = 0 can be used to find a zero of the function.
(d) The graph has a double root at x = -7/2.
(e) The graph intersects the y-axis at y = 49.
What is the function of the graph?The graph of a function f is the graph of the equation y = f (x).
The function is given as:
[tex]\rm y = 4x^2 + 28x + 49[/tex]
Express 28x and 14x + 14x; so, we have:
[tex]\rm y = 4x^2 + 14x+14x + 49[/tex]
Factorize
[tex]\rm y = 4x^2 + 14x+14x + 49\\\\y = 2x(2x+7)+7(2x+7)\\\\y=(2x+7)(2x+7)[/tex]
Express as a perfect square
[tex]\rm y = (2x+7)^2[/tex]
This means that the graph of the equation has a double root.
It also means that 2x + 7 = 0 can be used to determine the root/zero of the function.
Substitute 0 for x in to determine the y-intercept
[tex]\rm y = (2x+7)^2\\\\\rm y = (2(0)+7)^2\\\\\rm y = (0+7)^2\\\\y=49[/tex]
This means that the graph intersects with the y-axis at y = 49
Hence, the true statements are (b), (d), and (e)

Answer:
1/27
Step-by-step explanation:
Okay first, calm down. Math is always hard when your stressed.
First step is to elimate b and write the equation in terms of a. So rearrange a-b=3 to b=a-3. Substitue that into the equation. Now you have :
27^1/3(a-3)
---------------
9^1/2(a)
Now rewrite the equation in terms of 3, you do this by realizing that 9 is simply 3^2 and 27 is simply 3^3. This gives you
3^(a-3)
---------
3^a
Now you use the laws of powers, and you get 3^-3, which is essentially 1/27.
pls lmk the answer please
Answer:
Step-by-step explanation:
The only way I can solve this is by assuming the letter on the far left is a B. If that is the case, <BAC and <EAC are supplementary.
Ignore the line going from C to D and look at the angle that is left. <EAC is out in the open. What happens is that <EAC and <BAC share the same starting poing which is A.
Each of the angles divide the diameter in two. The construction makes a total angle of 180 degrees which makes them supplementray.
<BAC + <EAC = 180o
<EAC = 31 degrees Given. Substitute that value into the equation above.
<BAC + 31 = 180 Subtract 31 from both sides.
<BAC +31-31 = 180 - 31 Combine
<BAC = 149

One side of an enlargement of the rhombus is shown by the dotted line.
A)Complete the enlarged rhombus.
B) What is the scale factor of the enlargement?
HELP
Answer:
A) see attached
B) 2
Step-by-step explanation:
A)See the attachment for a completed enlargement of the given rhombus.
__
B)The enlarged side shown in the problem statement is twice as long as the nearest parallel side of the rhombus. The scale factor is the ratio of the enlarged side length to the original side length: 2 : 1. The scale factor is 2.
_____
Additional comment
There are several ways you can determine the scale factor. The endpoints of the image side are twice as far from the center of the rhombus as the original rhombus vertices. (The original extends 1 unit left, for example, while the enlargement is 2 units left.)
The length of a side of the original (blue) rhombus is the diagonal of a 1×2 rectangle on the grid. The drawn side of the image is two such lengths.

If triangle RST and triangle XYZ are similar, which of these equations must be true?
Answer: A
Step-by-step explanation:
If they are similar, that means the proportions for corresponding sides will be the same.
I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives because the XYZ picture is not lined up with the similarity it has with RST.
(A) says that side ST is corresponding with side YZ,
[] Triangle RST and triangle XYZ
-> Correct
(A) also says that side RT is corresponding with size XZ,
[] Triangle RST and triangle XYZ
-> Correct
This means that option A is the correct answer.

Answer 1 :-Here, We have
Initial velocity = 0 , as jeepney started from rest Time = 2 seconds Distance = 20 mTherefore,By using second equation of motion
[tex]\sf{ S = ut {\times} }{\sf{\dfrac{1}{2}}}{\sf{at^{2}}}[/tex]
Subsitute the required values,

Hence, The acceleration of the jeepeny is 10 m/s² .
Answer 2 :-Here, we have
Initial velocity = 0 , as the coins started rolling from rest. Acceleration = 4 m/s²Time = 3 secondsTherefore,
By using second equation of motion
[tex]\sf{ S = ut {\times} }{\sf{\dfrac{1}{2}}}{\sf{at^{2}}}[/tex]
Subsitute the required values,

Hence, The coin will reach 18 m after 3 seconds.
Answer 3 :-Here,
A stone fell from a 45 m high cliff and hit the ground.So,
Initial velocity = 0Distance = 45 mAcceleration due to gravityBy using third equation of motion

Subsitute the required values,
[tex]\sf{ v^{2} = 0^{2} + 2{\times}9.8{\times}45 }[/tex]
[tex]\sf{ v^{2} = 90{\times}9.8}[/tex]
[tex]\sf{ v^{2} = 882 m}[/tex]
[tex]\sf{ v = \sqrt{882} m}[/tex]

Answer:
Below in bold.
Step-by-step explanation:
The hexagon is made up of 6 equilateral triangles.
So the Base = 12 cm.
Height a = 12 cos 30 = 10.392 cm
So area of 1 triangle = 1/2 * 12 * 10.392 cm^2
- and total area = 6 * 1/2 * 12 * 10.392
