Answer:
31
Step-by-step explanation:
Using PEMDAS we know that you start with parenthesis, which would give us twenty within the brackets. Then you would solve for the exponent, which would give you sixteen but you do not add the exponent to the parenthesis until you divide. 100 divided by 20 is five, then you add ten and sixteen, giving you 31.
Answer:
-13

Have a nice day !
Y=2(x-3)^2 +7 would be the way to rewrite this equation in vertex form.

<h3>
<em>x=45degrees</em></h3>
<h2>
Step-by-step explanation:</h2>
Let the angle to be solved be x
Let the supplement/compliment by y
x+y=90 Complimentary angles add up to 90 degrees.
x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:
x+y=90 Isolate x:
x=90−y Input into the other equation:
(90−y)+3y=180 Combine like terms, isolate y and its coefficients:
2y=90 Isolate y
y=45 Input into the first equation:
x+45=90 Isolate x:
x=45degrees
Answer:
Step-by-step explanation:
x²+y² = 5²
3²+y² = 25
y² = 16
y = ±√16 = ±4
Since the terminal side is in quadrant IV, y = -4
sinθ = -4/5
