Answer:

C. cos E

Step-by-step explanation:

We have been given a right triangle DEF. We are asked to find the trigonometric ratio, which has the same value as sin D.

We know that measure of angle F is 90 degrees as all angles of triangle add up-to 180 degrees. The side DE is hypotenuse of triangle DEF.

Let us find sin D for our given triangle.

\text{Sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

\text{Sin(D)}=\frac{\text{FE}}{\text{DE}}

We know that cosine relates adjacent side of right triangle to hypotenuse.

\text{Cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}

We can see that FE is adjacent side of angle E, so:

\text{Cos(E)}=\frac{\text{FE}}{\text{DE}}

Therefore, cos E has the same value as sin D and option 'C' is the correct choice.

Find the factorization of the polynomial
makvit [3.9K]
There is only one real root, at x=-2, so the polynomial describing this parabola has factors of (x+2) with multiplicity 2. The y-intercept tells you the vertical stretch is 1.

The factorization is y = (x +2)².

A line passes through the point (-1,-5) and has a slope of -5.
Anna71 [15]
<h3>hello!</h3>

We're given a point that the line intersects and its slope.

Let's use Point-slope:-

\boxed{y-y1=m(x-x1)}

y1 = -5

m=-5

x1=-1

\boxed{y-(-5)=-5(x-(-1)}

\boxed{y+5=-5(x+1)}

Convert to slope-intercept:-

\boxed{y+5=-5x-5}

\boxed{y=-5x-5-5}

Finally,

\bigstar{\boxed{\pmb{y=-5x-10}}

<h3>note:-</h3>

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
