Answer:
-6
Step-by-step explanation:
given
x³ = -216
x = (-216)^⅓
factorize
x = [(-6)×(-6)×(-6)]^⅓
x = -6
Answer
second one
Step-by-step explanation:
<h2>
Coordinate Pairs</h2>
Coordinate pairs are organized like (x,y).
- x tells us the location of the point in relation to the x-axis, the axis that is horizontal.
- y tells us the location of the point in relation to the y-axis, the axis that is vertical.
To determine a coordinate pair, we can determine each coordinate individually, then put them together.
<h2>Solving the Question</h2>
Notice how the red point sits on the very edge of the graph.
When we look at the x-axis, we can see that it occurs at the number 0 on the x-axis. In other words, the red point occurs when x=0.
When we look at the y-axis, we can see that it lines up with the number 2. In other words, the red point occurs when y=2.
Therefore, when we put the two coordinates together like (x,y), we get (0,2).
<h2>Answer</h2>
(0,2)
For this, the number we are looking for is x.
use this formula... 17 - 3 = 2x
therefore, 14 is your doubled number.
14 divided by two is 7.
your mystery number is 7
Circumference = 360 degrees
<span>Circumference = 2π radians (comes from 2*pi*radius) </span>
<span>Therefore </span>
<span>360 deg. = 2*π radians </span>
<span>180 deg. = π radians </span>
<span>1 deg. = (π/180) radians </span>
<span>75 deg. = 75(π/180) radians </span>
<span>75 deg. = 75π / 180 radians </span>
<span>don't bother to try and simplify π (it is an irrational number) </span>
<span>however you can simplify 75/180 </span>
<span>both are divisible by 5 </span>
<span>75π/180 = 15π/36 </span>
<span>both are divisible by 3 </span>
<span>75 deg. = 5π/12 radians </span>
<span>We normally don't bother to go further, unless you actually need it as a decimal fraction (in which case, you will have an approximation) </span>
<span>75 deg. ≈ 1.308997 radians</span>
