We need to find a cosine function:
The amplitude represents half the distance between the maximum and minimum values of the function and the period goes from the x-value of one peak to the x-value of the next one. Therefore:
Finally:
And y(4) is:
Answer:
x=25
Step-by-step explanation:
DEF=180, Therefore GED+GEH+HEF=180
x+30+x+40+2x+10=180
Combine like terms:
4x+80=180
subtract 80 by both sides:
4x=100
divide by 4 on both sides
x=25
I believe it would be .21m. So for example.The memory stick is sold normally for $14, so to plug it into the equation it would be: .21(14), which gives you the discount of $2.94. Subtract that amount from the original price, and that gives you the sale price. .21(14)=2.94 14-2.94=11.06~~~~~Sale price
60
due to alternate interiors the angle supplementary to x is 120
120 + x = 180
x = 60
