What is the rate change of the table?

Mathematics
1 answer:
Tems11 [23]3 years ago
4 0

The rate of change is $27 per month if the change in y values is 54 and change in x values is 2.

<h3>What is the rate of change?</h3>

It is defined as the change in values of a dependent variable with respect to the independent variables.

From the data given in the table, we can find the rate of change per month:

To find the rate of change:

= change in y/ change in x

= (138-84)/(4-2)

= 54/2

= 27 per month

Thus, the rate of change is $27 per month if the change in y values is 54 and change in x values is 2.

If the angle between each blade of the wind turbine is the same, and each blade has a length of 20 meters, find the distance bet
Ket [755]

A typical windmill has three blades. We can envision these blades in a circle, which a circle = 360 degrees. We want to divide up the angles of the blades so they are even or makes up 360 degrees. We have three blades so we have 3 angles to divide by 360 degrees. So, 360 / 3 = 120 degrees. Now that we know the angle of the blades, we can use the Law of Cos to solve the distance between the blade tip.


Law of Cos

c^2 = a^2 + b^2 - 2(a)(b)(\cos A)


We know

a = 20

b = 20

A = Angle = 120


We need to solve for c

c^2 = a^2 + b^2 - 2(a)(b)(\cos A)


Take the square root of each side of the =

\sqrt{c^2} = \sqrt{a^2 + b^2 - 2(a)(b)(\cos A)}

c = \sqrt{a^2 + b^2 - 2(a)(b)(\cos A)}

Input the values we know into the formula and solve for c:

c = \sqrt{a^2 + b^2 - 2(a)(b)(\cos A)}

c = \sqrt{20^2 + 20^2 - 2(20)(20)(\cos 120)}

c = \sqrt{400 + 400 - 2(20)(20)(\cos 120)}

c = \sqrt{800 - 2(20)(20)(\cos 120)}

c = \sqrt{800 - 2(400)(\cos 120)}

c = \sqrt{800 - 800(\cos 120)}

c = \sqrt{800 - (-400)}

c = \sqrt{1200}

c = 20\sqrt{3}

c = 34.641016

c = 34.64


We now have our answer, which is 34.64 and that is C.

PLEASE HELP!!! <br> If m&lt;B=m&lt;D=42 find m&lt;c so that quadrilateral ABCD is a parallelogram
MissTica
The oposite angles must be equal and adjacent angles must be supplementary

so
D=B and A=C
and
A+D=180=A+B=B+C=C+D
so ifD=42, then

A+D=180
A+42=180
minus 42 both sides
A=138=C

angle C has to be 138 degrees
