What are the solutions to the equation<br><br>x^2+14x=-130<br><br>please do a step by step
Serjik [45]

Answer:

The answer to your question is:  x1 = - 7 + 9i      x2 = -7 - 9i

Step-by-step explanation:

                                             x² + 14x = - 130

                                            x² + 14x + (7)² = -130 + (7)²

                                           (x + 7)² = -81

                                            x + 7 = ± √-81

         i² = -1,  then                x + 7 = ±√ 81i²

                                            x + 7 = ± 9i

                          x1 = -7 + 9i                         x2 = -7 - 9i

Simplify sine squared theta divided by the quantity 1 minus sine squared theta..
timama [110]
Answer: tan^2ø
(i’m gonna use ø as theta because i can’t find it)

explanation:
sin^2ø-1=cos^2ø because of one of the pythagorean identities

sin^2ø/cos^2ø is tan^2ø because sin/cos is tan- opposite/hypotenuse divided by adjacent/hypotenuse is opposite/adjacent

hope that helps- you can comment if you need any more explanation :)

You buy 1 1/4 yards of fabric and $8 clothing pattern. Your total cost with a 6% sales tax added is $18.55. What is the cost per
Anna35 [415]

Answer: The fabric costs $7.60 per yard.

Step-by-step explanation: First we can divide it by 106 then multiply it by 100 to get rid of the 6% sales tax, which now the cost of the stuff is $17.50. 

Next, we subtract 8 from this to represent the clothing pattern cost. Now it is $9.50.

The last stap to this is to divide it by 1 1/4 to get the final cost per yard: 

The fabric costs $7.60 per yard.
