Answer:
<em>a</em><em>}</em><em>4</em><em>/</em><em>3</em>
<em>b</em><em>}</em>
<em>c</em><em>}</em><em>-</em><em>1</em><em>/</em><em>4</em>
Step-by-step explanation:
a}4-c/4-(2+b)
putting the values of b and c n its place
4-(-4)/4-(2-4)
4+4/4-(-2)
8/4+2
8/6
4/3 or 1.33
b}IDK SORRY
c} y-x+5+y/4
-1-4+5-1/4
-6+5/4
-1/4

Answer:
The heat is produced by a 150-W light bulb that is on for 20-hours is 10200 BTU.
Step-by-step explanation:
To find : How much heat (Btu) is produced by a 150-W light bulb that is on for 20-hours?
Solution :
A 150-W light bulb is on for 20-hours.
The heat produced by bulb is given by,


We know that,

Converting W-hr into BTU,


Therefore, The heat is produced by a 150-W light bulb that is on for 20-hours is 10200 BTU.
Transformation of Periodic Functions [cos(x)]
For horizontal shifting: +c (left) -c (right)
For vertical shifting: +d (up) -d (down)
For horizontal scaling (period): b↑ compressing b↓ stretching
For vertical scaling (amplitude): a>1 stretching 0<a<1 compressing
