Supplementary angles are when the sum of 2 angles is 180 degrees this does not mean the angles are congruent, the only way for them to be congruent is if they both were 90 degrees.
"A clock is positioned on an auditorium wall with its center 9 feet above the floor. The second hand is 10 inches long and continuously moves around the clock. Let x represent the time in seconds measured from noon on a given day. Which f(x) represents the height above the floor, in feet, of the tip of the second hand?"
Answer: f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.
Step-by-step explanation:
When we have a circular motion, we can write this as:
f(x) = A*sin(k*x + f) + A*cos(k*x + f) + C.
where:
k is a constant that depends on the period.
f is a phase shift.
C is the mean height of the circular motion, in this case will be equal to the height of the center, that is 9ft.
C = 9ft.
A is the amplitude of the motion, in this case is equal to the radius, that is equal to the lenght of the second hand
A = 10in
But we should write both quantities in the same units, so we have:
1ft = 12in
then:
C = 9ft = 9*12in = 108in
Then our equation is:
f(x) = 10in*cos(k*x + f) + 10in*sin(k*x + f) + 108in
now, x = 0s coincides with the noon
so at x = 0s, the second hand is pointint to the twelve, this means that is in the max height, so we have:
F(0s) = 10in*cos(0 + f) + 10in*sin(0 + f) + 108 in
Now, the maximum value will be when the value inside the sinusoidals is 0.
(because cos(0) = 1 and sin(0) = 0)
then we have that f = 0.
Now, we know that it takes 60 seconds to do a full revolution, and for the sinusodial functions the period is 2*pi
Then we have:
c*60s = 2*pi
c = 2*pi/60s.
Then the equation is:
f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.

What is the common difference in the arithmetic sequence 30, 27, 24, 21, 18...?
Answer:
-3
Step-by-step explanation:
To find the common difference take the second term minus the first term
27 - 30 = -3
Check by taking the third term and subtracting the second term
24 - 27 = -3
The common difference is -3

What value of y satisfies the system of equations {9x+2y=24y=6x+19
Step-by-step explanation:
Equation 1: 9x + 2y = 24y, 9x = 22y, x = 22/9 y.
Equation 2: 24y = 6x + 19,
24y = 6(22/9 y) + 19
24y = 44/3 y + 19
28/3 y = 19
Hence, y = 19 * 3/28 = 57/28.

Answer:
x ≥ 1: first photox ≥ 3: second photoI am confused. what is 5r– 7 = 2r+ 14
Answer:
r=7
Step-by-step explanation:
5r-7=2r+14
add sevento both sides
5r=2r+21
Subtract 2r from both sides.
3r=21
divide both sides by 3
r=7

The figure above shows the graph of h(x) = x+1−−−−√3– 2, a translation of the parent function g(x) = x−−√3. How is the graph of the parent function translated?
Question 5 options:
A)
Left 1 unit and up 2 units
B)
Left 1 unit and down 2 units
C)
Right 1 unit and up 2 units
D)
Right 1 unit and down 2 units
Answer:
B.
Step-by-step explanation:
The graph is translated 2units to the left and 1 unit up.
What is transformation of graph?Transformation of a graph is defined as the changes in the shape of the coordinate plane of the given function by rotation, reflection and translation. Translation is rigid movement in the parent graph either vertically or horizontally.
According to the question,
Parent square function f(x) is transformed to create a new function g(x) .
f(x) = √x
g(x) = √x-2+1
As we can see x is shift by x-2 which explains graph is translate 2 units to the left.
(x-2+1) : +1 is representing 1 unit up.
Hence, the graph is translated 2units to the left and 1 unit up.

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.
To the nearest meter, how many meters are in 119 inches?
Answer:
there is 5.0546meters
Step-by-step explanation:
1m=100cm
x =2.54cm
2.54cm=0. 0254m
so,
0.0254m=1inch
y =199inch
y = 0.0254×199m
y=5.0546m
