Answer:
(-∞, 4]
Step-by-step explanation:
The range of the function is the values that the output can take
Y goes from negative infinity to and including 4 ( assuming the scale is 1)
(-∞, 4]
Answer:
280x + 37
Step-by-step explanation:
Sin angle that equals the 1/2 value is the 30 degree on the 1st Quadrant.
The angle of 30 degree on the 3rd Quadrant is equivalent to (formula and circle in the 1st photo) 180 + 30 = 210°.
So theta = 210° (3rd Quadrant) = 30° (1st Quadrant).
Now just transfer the cos 30° to the 3rd Quadrant and the signal will be negative (as shown in the 2nd photo attached).
Answer:
Step-by-step explanation:
The initial expression is:
Using BEMDAS (Brackets - Exponents - Multiplication - Division - Addition -Subtraction), we first start with brackets:
Remember that if there is a negative sign, it will change the signs of the terms within the brackets.
Then, collecting like terms:
