Answer:
D) 41.81 degrees
Step-by-step explanation:
In this problem, we are given a leg length (a=12) and the hypotenuse (c=18).
We need to select which trigonometric identity to use with the acronym SOHCAHTOA:
SOH -> sine=opposite/hypotenuse
CAH -> cosine=adjacent/hypotenuse
TOA -> tangent=opposite/adjacent
Given side a is opposite of angle A and side c is the hypotenuse, we clearly need to use the sine function.
Set up an equation based on the information you have:
sin(A)=12/18
Now take the inverse:
sin^-1(sin(A))=sin^-1(12/18)
A=41.8103149
So the best option is answer D) 41.81 degrees

Insert the graph picture here:
Graph please
Answers
Answer:
y = 33.75 m/s.
Step-by-step explanation:
The graph of the rocket's velocity with respect to time looks as follows :
[tex]y=0.15x^2[/tex] ...(1)
Where x is time in seconds
We need to find the velocity of rocket after 15 seconds. Put x = 15 in equation (1).
[tex]y=0.15\times (15)^2\\\\=33.75\ m/s[/tex]
Hence, the speed of the rocket after 15 seconds is 33.75 m/s.

Step-by-step explanation:
Given the expression

[tex]\mathrm{Convert\:element\:to\:fraction}:\quad \:2ab^2=\frac{2ab^25}{5}[/tex]
[tex]2ab^2-\frac{a^2b^2}{5}=\frac{2ab^2\cdot \:5}{5}-\frac{a^2b^2}{5}[/tex]
[tex]\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=\frac{2ab^2\cdot \:5-a^2b^2}{5}[/tex]
[tex]=\frac{10ab^2-a^2b^2}{5}[/tex]
Thus,
[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]

Find the equation of a line parallel to y = 12 that contains the point (3, 2).
Answers
Answer:
y = 2
Step-by-step explanation:
Let's first write the equation of y = 12 in slope-intercept form. Slope-intercept form is represented as:
y = mx + b
Where...
m: slope
b: y-intercept (the y-value at where the line intercepts the y-axis)
(x, y): any coordinate on the line
This line has a slope of 0 and a y-intercept of 12, therefore its equation is:
y = 0x + 12.
Parallel lines have the same slope. Therefore the equation of the parallel line can be represented as:
y = 0x + b
We need to find b, or the y-intercept.
Let's substitute the point given to us into the equation.
Solve for the y-intercepty = 0x + b
2 = 0(3) + b
2 = 0 + b
b = 2
Therefore the equation of a line parallel to y = 12 that contains the point (3, 2) is y = 2.

Sakura's house is at an elevation between 113 m and 120 m above sea level. Her friend Ted lives about 15 m below her. Choose the compound inequality that describes the elevation x of Ted's house. Part B Ted lives between _____m and _______m above sea level.
Answers
The compound inequality to describe the elevation of Ted's house is 135 > x > 128.
Ted lives between 128m and 135m above sea level.
How to explain the inequality?Now it is given that,
Sakura's house is at an elevation between 113 m and 120 m above sea level.
Let x be the elevation of Sakura's house.
So, 120 > x > 113
Now Ted lives about 15 m below her
Ted's house elevation = x - 15
So, the compound inequality to describe the elevation of Ted's house,
120 > x - 15 > 113
Adding 15 to the inequality we get,
120 + 15 > x - 15 + 15 > 113 + 15
Solving we get,
135 > x > 128
This is the required compound inequality.
Thus, the compound inequality to describe the elevation of Ted's house is 135 > x > 128.

A 12 foot board rests against the wall. The angle that the board makes with the ground is 60 degrees. How far is the base of the board from the wall?
Answers
Answer:
6 foot
Step-by-step explanation:
Since the board is 12foot and the angle makes 60 degrees to the wall, we can assume that it is the 30,60,90 degreees. 30,60,90 degrees triangle makes the side of x, 2x ,and xroot3.
Hence, the board(12foot) is equal to 2x.
