Answer:

Nill, there is no square root for negative figures

Step-by-step explanation:

Getting the square root of a negative figure is impossible. Only Positive integers and positive fractions can be manipulated to get their square root.

Anyways, the square of -1 is calculated as follows.

-1^{2} =

-1 x -1 = 1

Answer: √−1=i.

Step-by-step explanation: When we say that the square root of a negative number "doesn't exist", we mean that there is no real number solution. However, if we consider complex numbers, we then get a solution to √−1=i.

Answer:

11

Step-by-step explanation:

So every 12 weeks there are 4 jars right? right.

1.) Divide 33 by 12 and you will get 2.75

2.) Then multiply 2.75 by 4 and you will get 11!

The problem is a bit hard to understand but I hope I answer your question correctly! Have a great day! :)

Francisco has a savings account balance of 2,033.88. The interest rate on the account is 2.9% compounded monthly. If he opened t
inna [77]
Let P = the value of the initial deposit.

Given:
A = 2,033.88, the current amount
r = 2.9% = 0.029, interest rate
n = 12, compounding interval
t = 9  years

Then
A=P(1+ \frac{r}{n})^{nt}

That is,
P(1 + 0.029/12)¹⁰⁸ = 2203.88
1.2978P = 2203.88
P = $1,698.17

Answer: $1,698.17

Verify sine law by taking triangle in 4 quadrant<br>Explain with figure.<br>​
Ksivusya [100]

Proof of the Law of Sines

The Law of Sines states that for any triangle ABC, with sides a,b,c (see below)

a

 sin  A

=

b

 sin  B

=

c

 sin  C

For more see Law of Sines.

Acute triangles

Draw the altitude h from the vertex A of the triangle

From the definition of the sine function

 sin  B =

h

c

    a n d        sin  C =

h

b

or

h = c  sin  B     a n d       h = b  sin  C

Since they are both equal to h

c  sin  B = b  sin  C

Dividing through by sinB and then sinC

c

 sin  C

=

b

 sin  B

Repeat the above, this time with the altitude drawn from point B

Using a similar method it can be shown that in this case

c

 sin  C

=

a

 sin  A

Combining (4) and (5) :

a

 sin  A

=

b

 sin  B

=

c

 sin  C

Obtuse Triangles

The proof above requires that we draw two altitudes of the triangle. In the case of obtuse triangles, two of the altitudes are outside the triangle, so we need a slightly different proof. It uses one interior altitude as above, but also one exterior altitude.

First the interior altitude. This is the same as the proof for acute triangles above.

Draw the altitude h from the vertex A of the triangle

 sin  B =

h

c

      a n d          sin  C =

h

b

or

h = c  sin  B       a n d         h = b  sin  C

Since they are both equal to h

c  sin  B = b  sin  C

Dividing through by sinB and then sinC

c

 sin  C

=

b

 sin  B

Draw the second altitude h from B. This requires extending the side b:

The angles BAC and BAK are supplementary, so the sine of both are the same.

(see Supplementary angles trig identities)

Angle A is BAC, so

 sin  A =

h

c

or

h = c  sin  A

In the larger triangle CBK

 sin  C =

h

a

or

h = a  sin  C

From (6) and (7) since they are both equal to h

c  sin  A = a  sin  C

Dividing through by sinA then sinC:

a

 sin  A

=

c

 sin  C

Combining (4) and (9):

a

 sin  A

=

b

 sin  B

=

c

 sin  C
