Given that sine= 21/29, what is the value of cos 0, for 0° <0<90°? A -square root of 20/29 B -20/29 C 20/29 D square root
Stolb23 [73]

Answer:

Step-by-step explanation:

sin=y/r

cos=x/r

sin=21/29

cos=x/29

x^2+y^2=r^2

x^2+21^2=29^2

x^2+441=841

x=sqrt(841-441)

x=20

cos=20/29

                       

  Only              |

   sin +             |     All Positive

See the step-by-step

Step-by-step explanation:

How do you factor trinomials? -

You factor trinomials by using methods like FOIL multiplication and simple factoring patterns.

How can we check the binomial factors to verify that they are truly factors?

We can multiply the binomial factors out to see that they are truly factors.

Create an example of a trinomial and factor it to its binomial factors.

x^{2}+5x+6 factors into

(x+2)(x+3).

Sorry for the trashy answer.

A line through (-4,6) with slope-3/2 and graph
marin [14]

Answer:

y = -\frac{3}{2}x

Step-by-step explanation:

Given

Passes through: (-4,6)

Slope: -3/2

Required

The equation and graph

The equation is calculated as:

y = m(x - x_1) + y_1

Where

m = -\frac{3}{2}

(x_1,y_1) = (-4,6)

So, we have:

y = -\frac{3}{2}(x --4) + 6

y = -\frac{3}{2}(x +4) + 6

Open bracket

y = -\frac{3}{2}x -6 + 6

y = -\frac{3}{2}x
