Answers:

10) 30\°

11) 30\°

12) 45\°

Step-by-step explanation:

In this problem we have to find the angle of each expression:

10) cos(x)=\frac{\sqrt{3}}{2}

x=cos^{-1}(\frac{\sqrt{3}}{2})

x=30\°

11) sin(x)=\frac{1}{2}

x=sin^{-1}(\frac{1}{2})

x=30\°

12) tan(x)=1

x=tan^{-1}(1)

x=45\°

Write an equation of the parallel to 5x-6y=10 through the point (-6,-1) show all work
ioda

5x-6y=10

-5x       -5x

-6y=-5x + 10

y-yV1=m(x-xV1)

y+1 = -5 (x+6)

destribute the -5 to the parinthease.

y+1 = -5x - 30

 -1            -   1

y= -5x -31

The sum of the first 6 terms of a geometric series is 15,624 and the common ratio is 5. What is the first term of series?
Shalnov [3]

Answer:

<h2>4</h2>

Step-by-step explanation:

Suppose

  • S = sum of the six terms
  • a1 = the first term

\left. { S = a _ { 1 } \frac { 1 - 5 ^ { 6 } } { 1 - 5 } } \\\\ { \Leftrightarrow S = \frac { a _ { 1 } } { 4 } ( 5 ^ { 6 } - 1 ) } \\\\ { \Leftrightarrow a _ { 1 } = \frac { 4 S } { 5 ^ { 6 } - 1 } } \right.

then a1 = (4×15 624)÷(5^(6)-1)

            = 4
