Answer:
To simplify computations, mathematicians like to fit an angle's triangle into a circle with radius r = 1.
Step-by-step explanation:
Because the number 1 is called "the unit" in mathematics, a circle with a radius of length 1 is called "the unit circle".
60 because you turn 240 into a fraction so it would be 240/4 which means division so you get 60
Answer:
The range is [7, -infinity)
Step-by-step explanation:
Since the leading coefficient is negative and it is a degree 2 polynomial, it is a parabola opened for downwards.
Where are you from please write it
And if you find problem on answer respond me
y = 11/21
To solve this first evaluate the power (then calculate the sum):
<u><em>
</em></u>y - <u><em>
</em></u> = 5y +<u><em> (-5 + 7)</em></u>
16y - 9 = -5y + 2
Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):
16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2
16y + 5y = 2 + 9
Next Collect the like terms and calculate the sum:
<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>
21y = 11
Lastly divide both sides of the equation by 21:
<u><em>21y = 11</em></u>
y =
