The key calculation in this problem is figuring out <em>how many times 80 goes into 1,000,000</em>. I'll build up in steps here.
80 x 5 = 400. This gives us a building block on our way to 1,000,000. From here, we can go further and say that 400 x 5 = 2,000; that 2,000 x 5 = 10,000; and finally that 10,000 x 100 = 1,000,000. Altogether, starting from 80, that's
80 x 5 x 5 x 5 x 100 = 80 x 25 x 500 = <em>80 x 12,500</em>
So, since 80 goes into one million 12,500 times, it takes 12,500 minutes for the animal's heart to beat that 1,000,000 times.
The answer to number 18 is - 0.25 or 1/4

Answer:
The polynomial will be P(x) = - 5 (x + 2)²(x - 3)
Step-by-step explanation:
The degree of the polynomial P(x) is 3 and it has zeros at x = - 2 with multiplicity 2 and at x = 3 with multiplicity 1.
Therefore, (x + 2)² and (x - 3) are the factors of the equation.
Let the polynomial is
P(x) = a(x + 2)²(x - 3) ........... (1)
Now, the polynomial passes through the point (2,80).
So, from equation (1) we gat,
80 = a(4)²(-1)
⇒ a = - 5
Therefore, the polynomial will be P(x) = - 5 (x + 2)²(x - 3) (Answer)

$24.5
Answer:
shown below
explanation:
<em>first</em><em> </em><em>off</em><em>,</em><em> </em><em>you</em><em> </em><em>get</em><em> </em><em>the</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em> </em><em>and</em><em> </em><em>1</em><em>3</em><em>4</em>
12x=134+10
12x=144
<em>then</em><em> </em><em>you</em><em> </em><em>simplify</em><em> </em><em>which</em><em> </em><em>will</em><em> </em><em>look</em><em> </em><em>like</em><em> </em><em>this</em><em>:</em>
12x. 144
___ = ___
12. 12
144÷12=12
so the answer is option c.12
