( \frac{f}{g} )(4) =  \frac{f(4)}{g(4)}  =  \frac{ {4}^{2} + 2 \times 4 - 3 }{ {4}^{2}  - 9}  =  \\  =  \frac{16 + 8 - 3}{16 - 9}  =  \frac{21}{7}

(f + g)(4) = f(4) + g(4) = 21 + 7 = 28

artcher [175]
To solve this problem you must apply the proccedure shown below:

 1. You have:

 Sinα=opposite/hypotenuse

 α=62°
 opposite=x
 hypotenuse=15 ft

 2. When you substitute the values into  Sinα=opposite/hypotenuse, you obtain:

 Sinα=opposite/hypotenuse
 Sin(62°)=x/15

 3. You must clear "x", as below:

 x=(15)(Sin(62°))
 x=13.24 ft

 The answer is. 13.24 ft

P and a are both prime numbers. Find the values of p and q so that 6*54*p/q is a perfect cube.
daser333 [38]

6x54= 324

6x50=300

6x4=24

300+24=324

The previous nearest cube root is 216 and the next cube root would be 343.

p/q could be any prime number which there are a lot of.

im going to say p is 1 and q is 3

next you would divide 1 by 3

1/3=0.666666667

324x0.666666667=216 exact

  • 13 + 7 = 20 which is greater than 5
  • 5 + 7 = 12 which is not greater than 13
