The formula for the general sin function is
where b is the period and c is the phase shift. We are given a period of
and the formula to solve for b is
. We set up to solve for b:
. Cross multiply to get
and b = 8. Now for the phase shift. The formula for that is -c/b, and since we already know b, and we have a phase shift value of pi/2, we solve for c:
and
. Therefore,
. Putting all that together into the equation with the A value of 6, we have
. Factoring out the 8 then, the final equation is
, third choice down.
Answer:
1/3 of the burrito
Step-by-step explanation:
2 burritos. Cut each one in 3 pieces. And each friend gets one piece out of it.
1) 462/11= 42
42x7=294
2) 9.38/7= $1.34
3) 6/11= 0.54545454545455
4) 1/4= 0.25
2/9= 0.22222222222
3/10= 0.30
2/1= 2.00
1/5= 0.20
least to greatest- 1/5, 2/9, 1/4, 3/10, 2/1
5) 9/15= 0.6 > 60%
to turn into a percent, move 2 decimal places!
6) 10/4= 2.5
2.5x18= 45
7) 2/3= 0.66666666666
0.66666666666x7= 4.66666666667
12.4 / 6.2 = 2
so other side of enlarged rectangle = 1.8 x 2 = 3.6
Perimeter of enlarged rectangle = 2(3.6 + 12.4) = 32
Answer: 32 feet
------------------------
Another way to do:
12.4 / 6.2 = 2
SF = 2
The original rectangle has a perimeter of 16
Perimeter of the enlarged rectangle = 16 x 2 = 32
Answer: 32 feet
Answer:
y=35
Step-by-step explanation:
10(y+7)=12y
10y+70=12y
70=12y-10y
70=2y
70/2=y
35=y
therefore, y=35
