Answer:

-\frac{\pi }{6}

Step-by-step explanation:

arcsin(−1/2) = -arcsin(1/2)

In the table of common values,

-arcsin of 1/2 = π/6 = -π/6

Note: Memorize the results of the common values.

Answer: 330°

Step-by-step explanation:

arcsin means sin^-1

So, arcsin(−1/2) is sin^-1(−1/2).

Now,

Let y = sin^-1(−1/2)

y = -30°

If range is between 0° and 360° then,

y = 360° - 30°

y = 330°

4.65 x 10 to the 3rd power
yaroslaw [1]

Answer:

(4.65 x 10)^3 = 100,544.625

Step-by-step explanation:

First, multiply 4.65 by 10

46.5

Now multiply this number by itself 3 times

46.5 x 46.5 = 2,162.25

2,162.25 x 46.5 = 100,544.625

So the answer is 100,544.625

Hope this helps :)

9x - y = 15 2x + 8y = 28
faust18 [17]
9x - y = 15
2x + 8y = 28

Use the substitution method.
Solve for y in the first equation.

9x - y = 15
-y = 15 - 9x
y = -15 + 9x

Now plug in y into the second equation.
2x + 8(-15 + 9x) = 28
2x - 120 + 72x = 28
74x - 120 = 28
74x = 148
x = 2

Plug x back into the rewritten first equation.
y = -15 + 9(2)
y = -15 + 18
y = 3

x = 2, y = 3
