Sin 30=y/7 
y=3.5ft 
You would start with your sin equation ( Sin angle= opposite side over hypotenuse)since you are trying to find the Opposite side length. So you would have sin 30 equals y over 7. Then you multiply over 7 to both sides.Last find the value of sin 30( sin 30=.5) and multiply that by 7, your answer is 3.5ft

Find (g o f)(-1). *
klio [65]

Answer:

D  -9

Step-by-step explanation:

(g o f)(-1) = g(f(-1))

f(-1) = f(-1)  =  (-1)^{2}  +  2(-1) - 3\\=  1 - 2 - 3\\=  -4

g(-4) = -4 - 5 = -9

So, (g o f)(-1) = -9

The symbol ₁₂P₉ represents the permutations of 9  quantities out of 12.
By definition,
_{12}P_{9} =  \frac{12!}{(12-9)!} = \frac{12!}{3!}

From the calculator,
12! = 479,001,600
3! = 6

Therefore
₁₂P₉ = 479001600/6 = 79,833,600

Answer: 79,833,600

Of the $2400 Mr Calvin earned, he spent 3/8 on food, 1/3 on taxes and 1/6 on other expenses. Find out how much all this is in do
sattari [20]

Answer: $300

Step-by-step explanation:

Mr. Calvin earned  \$2400

He spent  \frac{3}{8} on food i.e.

\Rightarrow \dfrac{3}{8}\times 2400=\$900

\dfrac{1}{3}\quad \text{on taxes i.e.}\\\\\Rightarrow \dfrac{1}{3}\times 2400=\$800

\dfrac{1}{6}\ \text{on other expenses i.e.}\\\\\Rightarrow \dfrac{1}{6}\times 2400=\$400

Remaining money = 2400-900-800-400=\$300

So, he saved $300 after expenses
