Angle B = 68 degrees
Using the Law of Sines
b / sin(B) = c / sin (C)
b = sin (68) * c / sin (49)
b = 0.92718 * 3 / 0.75471
b = <span> <span> <span> 2.78154 </span> </span> </span> / 0.75471
<span> <span> <span> b = 3.6855745916

Answer:

b=4

Step-by-step explanation:

Let us draw a triangle ABC, with A = 63°, C = 49°, and c = 3.

In the triangle ABC,

A +B +C = 180°

63°+B+49°= 180°

B = 180°-63°-49°

B = 68°

Use Sine law to find b

\frac{c}{sin C}=\frac{b}{\sin B}\\\\\frac{3}{\sin49}=\frac{b}{\sin68}\\\\b=\frac{3\sin68}{sin49}\\\\b=3.7

In the nearest whole number b = 4

Is the relationship for Camille’s puppy’s weight in terms of time linear or nonlinear? Explain your response.
Irina18 [472]

Answer:

It is a linear function, because the line has no curve, and the line is constant

Step-by-step explanation:

In a non linear function there would be a curve in the line, in this line there is no curve so therefore it is linear function.

Explicit Formula

Just in case you don't know what this is, the explicit formula is the formula that solves for any term in the series without necessarily knowing what came before the term you are solving.

<em><u>Givens</u></em>

d = t_(n + 1) - t_n  You can take any term and the next term for this part of the formula

d = t_3 - t_2

t_3 = 1

t_2 = -7

d = 1 - - 7 = 8

a = -15

<em><u>Formula</u></em>

t_n = a + (n - 1)*d

t_n = -15 + (n - 1)*8

For example find the 5th term.

t_5 = - 15 + (5 - 1)*8

t_5 = - 15 + 4 *8

t_5 = -15 + 32

t_5 = 17  Which is what you have.

Recursive Formula

Computers really like this formula. They use it in what is called a subroutine and they pass values from one part of the program to a subroutine which evaluates the given and sends the result back. I'm telling you all this so you see why you are doing it. The disadvantage of it for humans is that you must know the preceding term to use the recursive formula.  

<em><u>Formula</u></em>

t_n = t_(n - 1) + d

<em><u>Example</u></em>

t_6 = t_(6 - 1) + d

t_6 = t_5 + 8

t_6 = 17 + 8

t_6 = 25

You can check this by using the explicit formula.
