How to find area of parallelogram with coordinates of verticles?

Mathematics
1 answer:
ExtremeBDS [4]3 years ago
5 0
You find a parallelogram area by this formula:
A=b\cdot h
Where b is its base and h, its height.
You get b's value applying distance between two points formula.
If A and B points form the base:
A(x_1,y_1)\;\;\;\;B(x_2,y_2) \\  \\ 
d_{AB}= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} =b

And h is the perpendicular distance between both bases.
You can visit next link to know further about it:

And in attached picture you can find an example in progress you may want to finish.

Can someone please help asap?<br> find f(-4) if f(x) = x2 - x
Marianna [84]

Answer:

20

Step-by-step explanation:

Given function f(x)=\[x^{2}-x\]

We need to find f(-4) which means we need to find the value of the function when x=-4 .

On substituting x=-4 in the given function:

f(-4)=\[-4^{2}-(-4)\]

Square of -4 is 16.

Hence, f(-4)=\[16+4\]

=20

Hence the value of the given function f(x)=\[x^{2}-x\] when x=-4 is 20.

If the volume of a cube is increased by a factor of 10 (so that the new volume is 10 times the size of the original volume), by
Alexeev081 [22]

Answer:

surface area of cube 10^{\frac{2}{3} } time

Step-by-step explanation:

given data

new volume =  10 time original volume

to find out

what factor surface area change

solution

we consider here side of cube is a

and volume is V

we consider here a is 2

then volume will be v1 = a³ = 2³ = 8

and surface area = 6a²    = 6(2)² = 24    ..........1

so if volume increase 10 time

than

V = 10 × v1

a³ = 10 × 8

a³= 80

a = 2 × ∛10

and

surface area increase here

surface area = 6a²

surface area = 6( 2 × ∛10 )²

surface area = 24 × 10^{\frac{2}{3} }    ............2

so from equation 1 and 2

surface area / surface area = 24 × 10^{\frac{2}{3} }  / 24

surface area = 10^{\frac{2}{3} }

so here surface area of cube will be 10^{\frac{2}{3} } time

I need step by step explanation for this!
damaskus [11]

Answer:

61

Step-by-step explanation:

  1. 13 - 1 = 12
  2. 12 ÷ 2 = 6
  3. Put 6 and 1 together: 61

Therefore, the number is 61

Let's check:

  1. 6 × 2 = 12
  2. 12 + 1 = 13

The sum of the two digits is 13, and we got that, so we are correct. The number is 61.
