Find the length of AB

Mathematics
1 answer:
Alenkinab [10]2 years ago
8 0

AB is about 53.74 so the answer is (A)

\sin(c)  =  \frac{opposite}{hypotenuse}

\sin(61)  =  \frac{47}{x}

(x)\sin(61)  =  \frac{47}{x} (x)

(x) \sin(61)  = 47

\frac{(x) \sin(61) }{ \sin(61) }  =  \frac{47}{ \sin(61) }

x = \frac{47}{ \sin(61) }

x  = 53.74

PLEASE HELP

Answer:

Step-by-step explanation:

You have 3 unknowns: a, b, and c.  It's our job to find them algebraically.  I'm going to start with the point where x = 0 and y = 7.  You'll see why in a minute.  Filling in the standard form of a quadratic

y=ax^2+bx+c  using (0, 7):

7=a(0)^2+b(0)+c  gives you that c = 7.  We will use that value now when we write the next 2 equations.  Now the point (-2, 19):

19=a(-2)^2+b(-2)+7  and

19=4a-2b+7 so

12 = 4a - 2b

Now for the next point (-1, 12):

12=a(-1)^2+b(-1)+7  and

12=a-b+7  so

5 = a - b

Now we have a system of equations (the 2 bold font equations) that we will solve by elimination:

 12  =  4a  -  2b

  5  =   a   -    b

Multiply the bottom equation by -4 to get a new system:

 12  =  4a  -  2b

-20  = -4a  +  4b

Add those together to get rid of the a terms and end up with

-8 = 2b so

b = -4

Now we can sub in -4 for b to solve for a.  I'm using the second bold type equation to do this:

5 = a - (-4) and

5 = a + 4 so

a = 1 and the equation for the quadratic function is

y=x^2-4x+7
