Two people swing a jump rope. The highest point in the middle of the jump rope is 76 inches above the ground, and the lowest point is 4 inches. The rope makes 4 revolutions per second. Write a model for the height of the rope in inches as a function of time in seconds given that the rope starts at its lowest point.
Answer:
h(t) = 36sin(1440x)+ 40
Step-by-step explanation:
Given the information:
highest point: 76 inches=>lowest point: 4 inches => 4 revolutions per second => period: [tex]\frac{1}{4}[/tex] per second = [tex]\frac{360}{\frac{1}{4} } =1440[/tex]y = a sin (bx+c) + k for different values of a, b, and c
=> Amplitude (a) = (highest point - lowest point) / 2 = 36
=> asymptom (k) = (highest point - lowest point) / 2 = 40
=> model for the height of the rope in inches as a function of time in seconds given that the rope starts at its lowest point is:
h(t) = 36sin(1440x)+ 40
Hope it will find you well.

Find the distance between the points (15, -11) and (15, -19).
Answer: 8
Step-by-step explanation:
Distance formula: square root x2-x1 squared + y2-y1 squared.
15-15=0
0 squared=0
-19- -11= -8
-8 squared=64
Square root 64= 8
Answer:
8 units
Step-by-step explanation:
the easiest way to work out the distance for these two points is to plot them on a linear graph. as they are in line (because they're both inline with 15 on the x-axis), you just have to count the numbers between -11 and -19. in this case there are 8 units between the two points.
I hope this was helpful :-)

HELP PLS!! Which postulate proves that ABC and EDC are congruent?
Evaluate f(x)=x+3for f(-2)
Answer:
f(-2) = 1.
Step-by-step explanation:
If we are solving for f(-2), we will simply need to substitute in '-2' for 'x'. This gives us:
f(-2) = -2 + 3
f(-2) = 1.
Evaluate f(x) = x + 3 for f(-2)
Given: x = -2
Plug in -2 for x in the equation:
f(x) = x + 3
f(-2) = (-2) + 3
f(-2) = 3 - 2
f(-2) = 1
f(-2) = 1
1 is your answer.

A laboratory technician can clean 34 pipettes every hour with an automatic washer. How many can he clean in 12 minutes? (Hint: Both time periods must be in the same unit of measurement)
Answer:
7
Step-by-step explanation:
you can do a ratio where you have 34 over 60 then cross multiply that ratio with x over 12 and 60x=408 and it equals 6.8 but I am assuming you have to round up.
Answer: 6.8
Step-by-step explanation:
34 in 60 minutes
In 12 minutes = ( 12/60) * 34
Which equation is represented by the graph below?
On a coordinate plane, a curve approaches y = negative 4 in quadrant 3 and then increases exponentially in quadrant 1. It crosses the y-axis at (0, negative 3).
Answer:
y = e^x - 4
Step-by-step explanation:
The missing options are
y = ln x - 3
y = ln x - 4
y = e^x - 3
y = e^x - 4
The function is defined in quadrant 3 and increases exponentially, then it is not a logarithm.
f(x) crosses the y-axis at (0, -3). Replacing x = 0 the last option, we get:
y = e^0 - 4 = 1 - 4 = -3
Answer:
y = e^x - 4

The length of a rectangle is 1 less than twice the width. Write the equation that could represent the area of the rectangle in terms of the width
Answer:
(W2-1)xW
Step-by-step explanation:
The beginning of the equation represents the length as the question states it is one less than twice the width. Because you need to multiply width and length to get area, you place the length equation and parentheses and multiply the answer to the equation by the width :) Hope this helps!
Based on the problem statement, we have a word problem before us, that is solving for the area of a rectangle with given sides.
Area = 2y^2-y
Given data
Let the Length of the rectangle be x
and let the width be y
From the statement "The length of a rectangle is 1 less than twice the width"
the length can we re-written as
x = 2y-1
We know that the area of a rectangle is
Area = Length*Width
Area = (2y-1 )* y
Area = 2y^2-y
hence the expression for the area is given as 2y^2-y

What is volume?Volume is the measure of the capacity that an object holds.
What is the formula for the volume of cylinder?The formula for the volume of cylinder is
[tex]v = \pi r^{2}h[/tex]
Where,
V is the volume of cylinder.
r is the radius of cylinder.
h is the height of cylinder.
π = 3.14
According to the given question
Height of the cylinder, h = 15 units
Radius of the cylinder, r = 12 units

Answer:
y = -3
Step-by-step explanation:
-3(y-5) = 24
Divide each side by -3
-3(y-5)/-3 = 24/-3
y - 5 = -8
Add 5 to each side
y-5+5 = -8+5
y = -3
Answer:
y= -3
Step-by-step explanation:
-3(y-5)= 24
Do distributive property so, -3y + 15= 24
Subtract 15 from both sides so, -3y + 15 - 15= 24 - 15
Divide -3 from both sides to leave y on one side so, -3/-3y= 9/-3
The answer would be y= -3.
