PLEASE HELP!!!!!!!!!!!!!

If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula.  m= \frac{4-(-3)}{4-(-1)}= \frac{7}{5}.  So our slope is 7/5.  The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is  y= \frac{7}{5}x- \frac{3}{2},  choice D from above.

What is the area of the regular polygon?
BartSMP [9]

Answer:

You could use the polygon area formula OR here's an easier solution

We draw the lines DC and DE

Angle ADC = 120°

Triangle ADC is a 30 60 90 triangle

In such a triangle Line AE = hypotenuse * sq root (3) /2

Line AE = 3 * 0.8660254038  = 2.5980762114

Line DE = 1.5

Area of Triangle ADE = .5 * 1.5 * 2.5980762114 =

1.9485571586   square meters and entire area of Triangle

ABC = 6 * 1.9485571586

which equals 11.6913429513  square meters

What is the length of BD?
I am Lyosha [343]

Answer:

10\sqrt{3}

Step-by-step explanation:

<u>Trigonometric Ratios </u>

This problem will be solved by the use of a trigonometric ratio called sine because it relates the opposite side of a given angle with the hypotenuse of the triangle.

Selecting the angle of 60° in triangle ABD:

<em>Sine Ratio </em>

\displaystyle \sin 60^\circ=\frac{\text{opposite leg}}{\text{hypotenuse}}

\displaystyle \sin 60^\circ=\frac{BD}{20}

Solving for BD:

\displaystyle BD=20\sin 60^\circ

Since

\sin 60^\circ=\frac{\sqrt{3}}{2}

\displaystyle BD=20\frac{\sqrt{3}}{2}

Simplifying:

\boxed{\displaystyle BD=10\sqrt{3}}

What does -5 subtract by positive 5
AVprozaik [17]

(-5) - 5

Is the same as -5 + -5

You can use K.C.C, keep, change, change, you keep the first number, change the equation sign, and change the second number.

The answer would be -10
