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:

Answer:
y=x^2 + 2
if you use a graphing calculator, you can see that is the answer
B. y = –3
C. y = 3
D. y = 12
y/6 = -2
y = -2x6
y = -12
Matt's homeroom could have raised more money than Melissa's despite having a lower percentage if their fundraising goal was higher. For instance, Melissa's room could have raised 63% of $500 ($315), while Matt's room raised 48% of $800 ($384).
The situation in which Matt's homeroom raised more money than Melissa's, despite having a smaller percentage, is possible if the two homerooms have different fundraising goals. Let's consider the following example:
In this scenario, although Matt's homeroom has a lower percentage of funds raised, they have collected more money than Melissa's homeroom because their initial fundraising goal was higher.
