What is the definition of radians?

Mathematics

It's the relation between the arc length of a circle, and the measure of angle. Before radians, we could only measure in degrees, and use pi to convert from arc length and circumference and angle measure. But, with the introduction of radians, it's much easier to map the relation. Hope it helps!

Solve the system by substitution y=10x y=-3x-104
NISA [10]

Answer:  (-8, -80)

<u>Step-by-step explanation:</u>

y = 10x

y = -3x - 104

Substitute "y" with "10x" into the second equation, then solve for x:

10x = -3x - 104

13x = -104         <em>added 3x to both sides</em>

  x = -8             <em>divided both sides by 13</em>

Next, substitute -8 for x into the first equation to solve for y:

y = 10(-8)

  = -80

Up 2 units = y shifted up by 2:
y = x^2 + 2
to the right 3 units = x shifted right (+) by 3:
y + 3 = x^2 +2
new equation:
y = x^2 - 1

garri49 [273]

Answer:

\sqrt[5]{25x^{2}y^{4}z^{6} }

Step-by-step explanation:

going to the 2/5 power is the the fifth root of a square. For fraction exponents going into radical form use the denominator as you root of and use the numerator as the exponent of the rest making sure to multiply any other exponents by that number and when there is no exponent treat it as having an exponent of one for the multiplying.
