Calculate the area of triangle ABC with altitude CD, given A (−3, −4), B (−6, 2), C (0, 0), and D (−4, −2). a. 14 square units b
babymother [125]

Answer:

  b. 15 square units

Step-by-step explanation:

We notice from the graph that AB is the hypotenuse of a right triangle 3 units wide and 6 units high. The Pythagorean theorem tells you the length of that will be ...

  AB = √(3^2 +6^2) = √45 = 3√5

Similarly, altitude CD is the hypotenuse of a right triangle 4 units wide and 2 units high, so its length will be ...

  CD = √(4^2 +2^2) = √20 = 2√5

The area is given by the formula ...

  A = 1/2bh

  A = 1/2(3√5)(2√5) = 15 . . . square units

Write the equation of a circle with center (-2, 0) and area = 64 pi
kozerog [31]

Answer:

The required equation in standard form is (x+2)^2+y^2=64

Step-by-step explanation:

The equation of a circle with center (h,k) an radius, r units is given by the formula;

(x-h)^2+(y-k)^2=r^2

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 64\pi

\pi r^2=64\pi

\implies r^2=64

We substitute these values into the formula to obtain;

(x--2)^2+(y-0)^2=64

We simplify to get;

(x+2)^2+y^2=64
