ANSWER
EXPLANATION
To find a positive angle that is coterminal with
We add multiples of 2π until we get a positive angle that is less than one revolution,
We add to obtain,
This simplifies to,
This is the first positive angle that is coterminal with
and is less than one revolution.
Let
x---------> first positive integer
x+1------> second positive integer
x+2-----> third positive integer
we know that
(x+1)*(x+2)=72-------> x² +2x+x+2=72 -------> x² +3x-70=0
using a graph tool-------> <span>I solve the quadratic equation
</span>see the attached figure
the roots are
x1=-10
x2=7
the answer is
first positive integer is x=7
second positive integer is x+1=8
third positive integer is x+2=9
Answer:
50
Step-by-step explanation:
quanto é 50% de 200 and this the right answer
7th grade: 62/120 of the class is made up of girls; (120-62)/120 of boys.
8th grade: 58/120 of the class is made up of boys; (120-58)/120 of girls.
Looking at the info for boys only: Compare (120-62)/120 with 58/120. What do you see?
When you multiple a whole number times itself the resulting product is called a square number or a perfect square or simply a square so 1,4,9,16,25,36,49,64,81,100.121,144 and so are all square number
