Quadrilateral ABCD has vertices A (-3, 0), B (2, 4), C (3, 1), and D (-4, -3). Calculate the perimeter of the quadrilateral. Rou
Andru [333]

Answer:

Perimeter of the Quadrilateral=20.78

Step-by-step explanation:

Perimeter of the Quadrilateral= AB+BC+CD+AD

Finding the sides of the quadrilateral using the Distance formula:

A(-3,0), B(2,4), C(3,1) and D(-4,-3)

AB=\sqrt{(2-(-3))^2+(4-0)^2}\\\\ =\sqrt{(2+3)^2+4^2}\\\\ =\sqrt{5^2+4^2} \\\\=\sqrt{25+16}\\\\ =\sqrt{41}\\

=6.40

BC=

         \sqrt{(3-2)^2+(1-4)^2} \\\\=\sqrt{1^2+(-3)^2} \\\\=\sqrt{1+9}\\\\ =\sqrt{10}

          =3.16

      CD=\sqrt{(-4-3)^2+(-3-1)^2} \\\\=\sqrt{(-7)^2+(-4)^2} \\\\=\sqrt{49+16}\\\\=\sqrt{65}\\\\ =8.06

AD=\sqrt{(-4-(-3))^2+(-3-0)^2} \\\\=\sqrt{(-4+3)^2+(-3)^2} \\\\=\sqrt{(-1)^2+(-3)^2} \\\\=\sqrt{1+9}\\\\=\sqrt{10} \\\\ =3.16

Perimeter of the quadrilateral= AB+BC+CD+AD

             =6.40+3.16+8.06+3.16

              =20.78

Solve the given equation. If necessary, round to four decimal places. log2 3 + log2 a = log2 10
cestrela7 [59]

Answer:

3.333 if the equation is: \log_2(3)+\log_2(a)=\log_2(10)

Step-by-step explanation:

Looks like you are saying those are base logarithms.

I think you have the equation:

\log_2(3)+\log_2(a)=\log_2(10)

Use product rule, that is, \log(uv)=\log(u)+\log(v).

\log_2(3\cdot a)=\log_2(10)

Both sides are the same except the insides.  If we want the left hand side to be the same as the right hand side, then we need 3a and 10 to be the same.

When are those the same?

Set them equal and find out!

3a=10

Divide boht sides by 3:

a=10/3

Perform the division in your calculator:

10 division sign 3

gives you 3.333333333(repeating).

Write a rule for the linear function in the table
Flauer [41]
We can use slope , point formula
y-y1=m(x-x1)
m is  a slope=(y2-y1)/(x2-x1)=(-10-(-7))/(2-1)=-3
for example, we take the point (1, -7)
y-(-7)=-3(x-1)
y+7=-3x+3
y=-3x-4
