(8,-9) = 4\cdot \:8+5\left(-9\right)=-13\quad :\quad \mathrm{True}

(-2,-1) = 4\left(-2\right)+5\left(-1\right)=-13\quad :\quad \mathrm{True}

(6,3) = 4\cdot \:6+5\cdot \:3=-13\quad :\quad \mathrm{False}

(-7,4) = 4\left(-7\right)+5\cdot \:4=-13\quad :\quad \mathrm{False}

21. If the area of the plane shape below is<br>36cm, find its height.​
mariarad [96]

Answer:

4 cm

Step-by-step explanation:

The figure is a parallelogram with area (A) calculated as

A = bh ( b is the base and h the perpendicular height )

Here A = 36 and b = 9 , thus

9h = 36 ( divide both sides by 9 )

h = 4 cm

After a storm, two street lights with the same length are leaning against each
Ray Of Light [21]

Answer:

c = 4.79 feet

Step-by-step explanation:

Given question is incomplete without a picture; find the question with the attachment.

Two poles AD and DB of same length are leaning against each other.

Distance between the poles (AB) = 45 feet

m(∠ADB) = 180°- (60 + 50)°

               = 70°

By sine rule,

\frac{sin50}{AD}=\frac{sin70}{45}=\frac{sin60}{DB}

AD=\frac{45\times (sin50)}{sin70}

      = 36.68 ft

Similarly,

DB = \frac{45\times sin60}{sin70}

     = 41.47 ft

Now c = DB - AD

           = 41.47 - 36.68

           = 4.79 feet
