Answer:
$9.75
Step-by-step explanation:
$3.90 per yard
So $3.90 for 1 yard = $3.90
$3.90 for 2nd yard =$3.90
1/2 of $3.90 for 1/2 yard so $3.90/2 = $1.95
$3.90
$3.90
+ <u>$1.95</u>
$9.75
Well then multiply 400 x 142 and get your answer of 56,800
Equals 10 hope this helps
The answer is -72. I added an attachment below for the steps.
Answer:
[-1, 7]
Step-by-step explanation:
If you mean ...
y = 4sin(2x) +3
then you can substitute the range of the sine function into the equation and evaluate it to find the range of y.
The range of sin( ) is [-1, 1], so the range of y is ...
4[-1, 1] +3 = [4(-1)+3, 4(1)+3] = [-1, 7]

<em>Comment on the problem statement</em>
The range of y = 4sin²(x)+3 will be different, and the range of 4sin(2x+3) will be different yet. It is usually a good idea to use parentheses around function arguments.
