Answer:

- 30

Step-by-step explanation:

\sin {}^{ - 1} ( -  \frac{1}{2} )  =

Using the identity,

\sin( - x)  =  - ( \sin(x) )

\sin( \frac{1}{2} )  =  \frac{\pi}{6}

so

\sin {}^{ - 1} ( \frac{ - 1}{2} )  =  -  \frac{\pi}{6}

Convert to degrees.

The best way to solve this is to put it into a proportion:
\frac{x}{84} = \frac{ \frac{1}{4} }{ \frac{3}{4} }
So you cross multiply to get:
21= \frac{3}{4} x (the 21 is from \frac{1}{4}•84)
Then multiply by \frac{4}{3}
And you get $28, so the reduced price would be $28.

Two cars are traveling in the same direction. The first car is going 40 mi/h and the second car is going 55 mi/h. The first car
dexar [7]

Answer:

The equation you are asking for is

40*(t+3) = 55*t,

where t is the time counted after the second car started.

The equation says that the distance covered by each car from the starting point to the catching point is the same for both cars.

For the geometric sequence of a1=2 and r=2 find a5
Brrunno [24]

Answer:

a_5 = 32

Step-by-step explanation:

The nth term for the geometric sequence is given by:

a_n = a_1 \cdot r^{n-1}

where,

a_1 is the first term

r is the common ratio

n is the number of terms.

As per the statement:

For the geometric sequence of a_1=2 and r=2

We have to find a_5

for n = 5;

a_5=a_1 \cdot r^{n-1}

Substitute the given values we have;

a_5 = 2 \cdot 2^4 = 2 \cdot 16

⇒a_5 = 32

Therefore, the value of a_5 is, 32
