Answer:
0.90 seconds
Step-by-step explanation:
We will see that one complete revolution takes (2π/7) seconds.
How long does it take the valve stem to complete one revolution?Here we have the function:
f(x) = 33sin(7x−π/12) + 33
The time needed to do a full revolution is given by the period of the function.
Remember that:
sin(x) = sin(x + 2π).
Then:
sin(7x−π/12) = sin(7*(x + T) −π/12)
Then we must have:
2π = 7*T
Where T is the period.
Solving for T, we have:
2π/7 = T
This means that one complete revolution takes (2π/7) seconds.

Solve for x
14x + 2 = 9x - 3
Answer:
[tex]x=-1[/tex]
Step-by-step explanation:
1) Subtract 9x from both sides.
[tex]14x+2-9x=-3[/tex]
2) Simplify 14x+2-9x to 5x+2.
[tex]5x+2=-3[/tex]
3) Subtract 2 from both sides.
[tex]5x=-3-2[/tex]
4) Simplify -3-2 to -5.
[tex]5x=-5[/tex]
5) Divide both sides by 5.
[tex]x=-1[/tex]

What is the slope of the line passing through the points (3,5) and (-1,7)?
-1/2
To find the slope of the line between two points, we use the equation (y2-y1)/(x2-x1)
Substitute the values given for the xs and ys:
(7-5)/(-1-3)
2/(-4)
simplify: -1/2
Write the equation of the line, in point-slope form, that passes through the points (-6, -11) and (-2, -3).
Answer:
6 ..........................
Which equation describes the line that passes through the points (-4, 19) and (2, -1)
Answer:
y=-5/2x+4
Step-by-step explanation:
find the slope by using y2-y1/x2-x1
-1-19/2-(-4)
simplify
-20/8
simplify
-5/2
use slope-intercept form, y=mx+b
since we know the slope, find b
plug in one of the ordered pairs into the equation
-1=(-5/2)(2)+b
simplify
-1= -10/2+b
simplify
-1=-5+b
add 5 to both sides
b=4
plug b into y=-5/2x+b
y=-5/2x+4

what is the slope of -7,2 and -7,4
Answer:
The slope is undefined
Step-by-step explanation:
We can find the slope using
m = ( y2-y1)/( x2-x1)
= (4-2)/( -7 - -7)
= (4-2)/( -7 +7)
= 2 / 0
When we divide by 0, the result is undefined
The slope is undefined
Answer:
Undefined
Step-by-step explanation:
Since there is two points we can use (-7,2) and (-7,4) to find the slope
Slope formula for two points:
y2-y1/x2-x1
4-2/-7+7
Which is
2/0
Since 2/0 is not possible the answer will be undefined

The number of years it will take for $510 to grow to $1,010.18 at 5 percent compounded annually is ____
Answer:
13.66 years
Step-by-step explanation:
Given data
P=$510
A=$1,010.18
R=5%
t= ln(A/P)/r
susbstitute
t= ln(1,010.18/510)/0.05
t=ln1.980/0.05
t= 0.683/0.05
t= 13.66
Hence the time is 13.66 years
Suppose g(x) = f(x - 1) - 5. Which statement best compares the graph of
g(x) with the graph of f(x)?
D is your answer i believe
Step-by-step explanation:
using g(x), -1, which is our change of x will go right. -5 is our change in y, so therefore it goes down. negative means down, positive means up for our change of y. for our change of x, negative goes right, and postive goes left. thats why i think the answer is d

The third term in an arithmetic sequence is 9 and the fifth term is 21 . If the first term if a1, which is an equation for the nth term of this sequence?
A:an=6n-9
B:an=14n+6
C:an=6n+14
D:an=9n-6
Answer:
A: an = 6n - 9
Step-by-step explanation:
third term in an arithmetic sequence is 9
a3 = a + 2d
a + 2d = 9
the fifth term is 21
a5 = a + 4d
a + 4d = 21
a + 2d = 9 (1)
a + 4d = 21 (2)
Subtract (1) from (2) to eliminate a
4d - 2d = 21 - 9
2d = 12
d = 12/2
d = 6
Substitute d = 6 into (1)
a + 2d = 9 (1)
a + 2(6) = 9
a + 12 = 9
a = 9 - 12
a = -3
nth term of this sequence = a + (n - 1)d
= -3 + (n - 1)6
= -3 + 6n - 6
= 6n - 9
an = 6n - 9
