Area of the triangle defined by the coordinates (-3, -4), (-7, 0), and (-3, 4).
qwelly [4]
Here: (Aₓ, Ay) = (-3,-4), (Bₓ, By) = (-7,0), (Cₓ, Cy) = (-3, 4)
Now, Formula of area of triangle is:

area = [Aₓ(By - Cy) + Bₓ(Cy - Ay) + Cₓ(Ay - By)] / 2

Substitute the values in to the expression, 
area = [-3(0-4) - 7(-4-(-4)) - 3(-4-0)] / 2
area = [-3(-4) -7(0) -3(-4)] / 2
area = [12-0+12] / 2
area = 24 / 2
area = 12

Final answer would be 12 units.

Hope this helps!

Determine whether the situation involves permutations or combinations. Then solve. How many ways are there to place an algebra b
Nikitich [7]

Answer:

<h2>The situation involves permutation</h2><h2>The number of arrangement is 120</h2>

Step-by-step explanation:

Given that

Algebra book=1  

Geometry book=1

Chemistry book= 1

English book= 1

Health book= 1

Total number of books N = (1+1+1+1+1)= 5

      Permutation is used to  determines the number of possible arrangements in a set when the order of the arrangements is crucial.

Number of arrangements = N!

Number of arrangements= 5*4*3*2*1=  120

(10.4)2 =<br> to the second power is the 2
Elden [556K]

Answer:

10.4^2 = 108.16

Step-by-step explanation:

10.4^2 = 10.4 * 10.4

10.4 * 10.4 = (10 * 10.4) + (0.4 * 10.4)

(10 * 10.4) + (0.4 * 10.4) = (104) + (4.16)

(104) + (4.16) = 108.16

What are the zeros of the function y = x2 + 10x – 171, and why?
vagabundo [1.1K]
To find the zeros, you have to factor the equation.
y=(x+19)(x-9)
This is because 19*-9=-171 and 19-9=10.
Now to make x=0, you have to make the equation
x+19=0
and x-9=0
To solve, isolate x on both equations.
This makes x=-19 and x=9.
