Answer:
The correct prove will be:
Step-by-step explanation:
Multiply and Divide by
=
⇒ Let = Ф and 7Ф =
= sin2Ф sin3Ф sin5Ф ÷ 2cosФ
= 1/2(2sin2Фsin5Ф)sin3Ф ÷ 2cosФ
= (cos3Ф - cos7Ф) sin3Ф ÷ 4cosФ
= 1/2(2cos3Ф sin3Ф) ÷ 4cosФ ∵cos7Ф = 0
= sin6Ф ÷ 8cosФ
= sin(7Ф - Ф) ÷ 8cosФ
= (sin7ФcosФ - cos7ФsinФ) ÷ 8cosФ ∵sin7Ф = 1
= cosФ ÷ 8cosФ
= 1/8
Hence, The correct prove will be:

Okay so first what you would do is figure out what 3/5 is as a decimal so you would divide 3 by 5 which is 0.6 so the percentage is 15.6%
Next turn it into a fraction which would be 15.6/1
Then multiply the numerator and denominator by 10
15.6= 15.6/1= 156/10
then to put it in simplest form divide 10 by 156 and that would be 15 and 6/10

Answer:
If each youth saves $10 daily, their weekly savings would be $1400. So they donated $1400 to the church.
Step-by-step explanation:
Let the daily pay plan for each youth be $y
Daily pay plan for 20 youth = $20y
Weekly pay plan = 7×20y = $140y
Assuming each youth saves $10 daily
Daily savings for 20 youth = 20×$10= $200
Weekly savings for 20 youth = 7×$200= $1400
If they used the early pay plan ($140y) to go swimming, they saved $1400 which they donated to the church.
Answer:
$375 saved or roughly 33%.
Step-by-step explanation:
With daily plan;
(15)4.00 = 60.00
(25)60.00 = $1,500.00
If the youth group saved up enough for each of them to swim 15 times and 25 students are attending, they originally had $1,500.00 saved for the trip.
With early pay;
(25)45.00 = $1,125.00
1,500.00 - 1,125.00 = $375 saved or roughly 33%.

Answer:
(5x-6)²=25x²-60x+36
Step-by-step explanation:
We use: (a-b)²=a²-2ab+b².
Thus we get
(5x-6)²=25x²-60x+36
Answer:
Expand((5⋅x−6)2)
=62+2⋅(−6⋅5⋅x)+(5⋅x)2
=36−60⋅x+25⋅x2
