Hello!

When trying to find the sine of an angle, we can use the following formula:

sin B = \frac{opposite}{hypotenuse}

In this case, we need to find the side opposite ∠B (which would be AC) and the hypotenuse (which would be BC). Now take the individual values of these two sides and insert them into the formula above:

sin B = \frac{(16)}{(17.46)}

Reduce the fraction above to reach a value of 0.92. We have now proven that the approximate value of sin B is 0.92

The answer to this problem is B.

I hope this helps!

Find the first four terms of the sequence given by the following.<br> an = 32+(n-1)-3, n=1, 2, 3...
natta225 [31]

The first four terms are 32,29,26,23

Step-by-step explanation:

Given sequence is:

a_n=32+(n-1)(-3)\\

We will put n=1,2,3,4

Putting n=1 in formula of sequence

a_1=32+(1-1)(-3)\\=32+(0)(-3)\\=32+0\\=32

Putting n=2

a_2=32+(2-1)(-3)\\=32+(1)(-3)\\=32-3\\=29

Putting n=3

a_3=32+(3-1)(-3)\\=32+(2)(-3)\\=32-6\\=26

Putting n=4

a_4=32+(4-1)(-3)\\=32+(3)(-3)\\=32-9\\=23

The first four terms are 32,29,26,23

Solve each equation for x.a)x-1=0b)x+1=0 c)x²-1=0 d)x²+1=0
lesya692 [45]

Answer

given,

a) x-1=0

adding both side with 1

   x = 1

b) x + 1 =0

subtracting both side by 1

    x = -1

c) x²- 1 =0

   x² = 1

taking square root

   x = √1

   x = 1

d) x²+ 1 =0

   x² = -1

taking square root

   x = √-1

   x = i (iota)
