since there are 2 girls and 6 boys the ratio right now is 1/3 and to solve the number of girls we subtract 5 from 8 to get 3 we then do 6/3 to get 2 and that means it has to be 2 times so the number of girls must be 10 and we want how much we add so we get 10-2=8.Now we get that we need to add 8 more girls

so it is basically \(3(x+2)^2(x-1)\)but when we siplify it we get \(3x^3+9x^2−12\) and that is \(3(x^3+3x^2-4)\)

Translation of the problem here: 2. Knowing that a line has slope m = -2 and that it passes through point D (-3, - 1), Determine the equation of the line. 3. Given point A (-2, 3), calculate the coordinates of point B (3k, k + 1) so that the coefficient angle of the line AB is m = 1/2

We get the graph when the slope of the line=-2

For pitcher A  the probability to strike out is 3/10,0.3, or 30% since it strikes out 3 times in 10 times

For pitcher B the probability to strike out is 4/7,0.571428571..., or 57.1428571...% since it strikes out 4 times in 7 times

we can obviously see that  0.571428571... is greater than 0.3 and 57.1428571...% is bigger than 30% so Pitcher B is more likely to get a strike

a)

  i)3600 since it is 60*60

  ii)when we round it it is still 3600 or if we round 1/3600 it is about 0.00027777777... 

b)so it is 1/212 and it is about 0.00471698113 to 0.0 hours or 0.283018868 to 0.3 minutes or 16.9811321 to 17.0 seconds

c)hours(underestimate) minutes(overestimate) seconds(overestimate)

We get about 14.1086909 since 20/4=5 and x=3 we simplify it into the equation 5e+3^0.6 and e is about 

2.71828182 also 3^-0.6 is about 0.517281858 so we get 13.591409+0.517281858 which is about 14.1086909

so we get y=4 and  x=3since the only integer for x^2+y^2=25 is 3,4,5 since \(\sqrt{25} \)=5 and by the pythagorean theorem either x or y=3 or 4 but to be specific we must check and ony 4=3^2-5 works so x=3 , y=4

a=3 b=5and c=-8 since we dd them all and get 0 so (a+b+c)*2=0 and 0/2=0 we do 0-8=-8 to get c,0-(-3)=3 to get a, and 0-(-5)=5 to get b.

so the product of abc=3*5*-8 and there is 1 negative number so the product is a negative number it is -(15*8)=(-120)

so a*b*c=-120

so you start the opposite way to make the equation ((((x-10)*2-10-10)*2-10)-10)*2-10=0  we make that (((x-10)*2-10-10)*2-10)-10=5 then it becomes (((x-10)*2-10-10)*2=25 and ((x-10)*2-10-10)=12.5 which is (x-10)*2=32.5 so that is x-10=16.25 so x=26.25 and he got 26.25 gold coins when he started
