Answer: a) the dependent variable is y, the amount he earns depending on x, the independent variable. x is the number of hours.
b) y = 5x + 10
c) Bobby earns $27.50 for the 3.5 hour job
Step-by-step explanation: use the function y=5x + 10 substitute 3.5 for x
y = 5(3.5) + 10
y = 17.5 + 10
y= 27.5
Answer:
402.9 $
Step-by-step explanation:
first you must turn foot into yards "every 3 foot = 1 yard"
3.33 , 4
then we will use the area=length x width formula
3.33 x 4 = 13.32 square yards
the cost of the carpet is
13.32 x 30.25 = 402.9$
exponents could be any number between 1 and 10
The correct answer is C. All reference angles must be less than 90 degrees.
This is helpful when learning more complex topics including circular trigonometry and the unit circle, because the reference angle (typically denoted as theta prime) has the same trig values (sine and cosine) no matter which quadrant the angle is located in. Additionally, the reference angle is always the smallest angle possible between the terminal side of the angle and the x-axis; therefore, it must always be less than 90 degrees or else another smaller (and thus correct) reference angle could be made in another quadrant.
Hope this helps!
