Find the area

A= l*w

A = (6 1/2) * (5 3/4)

6 1/2 =  (2*6+1)/2 =13/2

5 3/4 = (4*5+3)/4 = 23/4

A = 13/2 * 23/4

Find the distance between the two points in simplest radical form.
sweet-ann [11.9K]

Answer:

3\sqrt{13}

Step-by-step explanation:

Calculate the distance using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 9, 8) and (x₂, y₂ ) = (- 3, - 1)

d = \sqrt{(-3-(-9))^2+(-1-8)^2}

  = \sqrt{(-3+9)^2+(-9)^2}

  = \sqrt{6^2+81}

   = \sqrt{36+81}

   = \sqrt{117}

   = \sqrt{9(13)}

   = \sqrt{9} × \sqrt{13}

   = 3\sqrt{13}

Doss [256]

Answer:

Step-by-step explanation:

<em>First step is that you need to have the same denominators so 1/3=2/6</em>

<em>If she spent 1/6 on snacks and 2/6 on a book which means she spent 3/6</em>

<em>so the fraction of what she saved is 3/6 or 1/2</em>

Is sqrt(1 - sin^2 θ) = cos θ true? if so, in which quadrants does angle θ terminate?​
jonny [76]

Answer:

  I and IV

Step-by-step explanation:

Since 1-sin(θ)² = cos(θ)², the given equation is equivalent to ...

  √(cos(θ)²) = |cos(θ)| = cos(θ)

This will be true where the cosine is non-negative, in the first and fourth quadrants.

Answer:

Area of circle: 1662.57 cm

Circumference of circle: 144.57 cm

Step-by-step explanation:

Formula of area of circle:

pi x r2 or radius x radius

So, it's 22/7 x 23 x 23 = 1662.571429

Formula of circumference of circle:

2 x pi x radius OR

pi x diameter

Let's use the second method, to find diameter it is radius x 2 = 46

So,

46 x 22/7 = 144.5714286
