Answer:
0 is your answer
Step-by-step explanation:
Solve for y. Plug in -5/3 for x
y = -3(-5/3) - 5
Simplify.
First, multiply
-3 x -5 = 15
Next, divide
15/3 = 5
Finally, subtract
y = 5 - 5
y = 0

Answer:
Step-by-step explanation:
We are told the wind turbine makes 76 revolutions in 1 minute. This means the angular speed of the object in revolutions per minute (rpm) is:
(1)
However, we have to convert this to , since this is the unit used in the International Systme of Units for angular speed.
So, we can do this knowing that:
(2)
Where:
is the value of one revolution
is the period of rotation
With this information in mind, let's make the conversion:
(3)
(4) This is the wind turbine angular speed
the scientific notation is just another mumble jumble way to write the same thing without so many repetitive zeros, so hmmm 780000 has 4 zeros, so what we do is we can say
78 and 4 zeros following it
or we can say
78 * 10⁴, if we get that product, is 780000
in scientific notation, we only leave one digit to the left of the decimal point
so the same thing above can be written as
78 * 10000, can be written as 78.0 * 10000
or as
7.8 * 100000
or as
0.78 * 1000000
check their product
7.8 * 100000, is really just 780000
because we moved the decimal to the left one more slot, it
became 7.8 * 100000
or in
<h2>scientific notation, 7.8 ⨉ 10⁵</h2>
