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?
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.
x=6

Find the equation of a line parallel to y = 12 that contains the point (3, 2).
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.
Write the standard form of the equation of the circle with center (−7,1) that passes through the point (−7,9).
Answer:
(x + 7)² + (y - 1)² = 64
Step-by-step explanation:
Use the equation of a circle, (x - h)² + (y - k)² = r²
Plug in the point and center, then solve for r:
(x - h)² + (y - k)² = r²
(-7 + 7)² + (9 - 1)² = r²
0 + 64 = r²
64 = r²
8 = r
Then, plug in the center and r² into the equation:
(x + 7)² + (y - 1)² = 64
So, (x + 7)² + (y - 1)² = 64 is the standard form of the circle's equation

Which solution value satisfies the inequality x – 6 ≥ –7?
Question 18 options:
A)
x = –5
B)
x = 0
C)
x = –2
D)
x = –7
Answer:
B) x = 0
Step-by-step explanation:
To find the solution value that satisfies the inequality x – 6 ≥ –7, you must plug every x value into the x and see which one works.
Plug -5 into x
-5 – 6 ≥ –7
Combine like terms
-11 ≥ –7
This is false, -11 is not greater than or equal to -7.
Plug 0 into x
0 – 6 ≥ –7
Combine like terms
– 6 ≥ –7
This is true, -6 is greater than -7.
Plug -2 into x.
-2 – 6 ≥ –7
Combine like terms
-8 ≥ –7
This is false, -8 is not greater than or equal to -7.
Plug -7 into x.
-7 – 6 ≥ –7
Combine like terms
-13 ≥ –7
This is false, -13 is not greater than or equal to -7.
B) x = 0 is the only solution that is true and works, so that is your answer.

Reduced form of 2ab^2-a^2 b^2/5
Answer:
[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]
Step-by-step explanation:
Given the expression
[tex]2ab^2-\frac{a^2b^2}{5}[/tex]
[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,

time looks as follows: y= 0.15x2
How fast is the rocket traveling after 15 seconds?
Insert the graph picture here:
Graph please
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.
