1953-1944=9 years (that's the years)
9 months between them
thus she was 9 years and 9 months
Find the lengths AB, BC and AC.
length AB= √(4²+(-4)²) = √32
length BC = √(4²+7²) = √65
length AC = √(8²+3²) = √73
From the lengths of this triangle it can be seen that no side is equal to the other and also it is not a right triangle.
So, triangle ABC is a scalene.
<span>Gymnast Clothing manufactures expensive hockey jerseys for sale to college bookstores in runs of up to 300. Its cost (in dollars) for a run of x hockey jerseys is
C(x) = 3000 + 10x + 0.2x2 (0 ? x ? 300)
Gymnast Clothing sells the jerseys at $105 each. Find the revenue function.</span>
Multiply both sides by 10 to clear the fractions.
2[10-5(x-2)]=x+1
distribute the 2 on the left hand side
20-10(x-2)=x+1
distribute the 10
20-10x-20=x+1
cancel out the 20
-10x=x+1
collect like terms
-11x=1
divide both sides by -11 to solve for x
x=-1/11
