Answer:
1 1/3
Step-by-step explanation:
When dividing, fractions, flip the second fraction. So, 8/9 divided by 2/3 will equal 8/9 times 3/2. Then, cross multiply and you will get 24/18. After that, simplify to get 4/3. At last, make it into a mixed number.
Answer:
$105.
Step-by-step explanation:
After one year her annual rate (AR) will have been $5 (5 percent of her savings (s))
S+AR(5%) --> $100+5 --> $150 after one year.
Consider the two functions as
<span>y1(x) =3x^2 - 5x,
y2(x) = 2x^2 - x - c
The higher the value of c, father apart the two equations will be.
They will touch when the difference, i.e. y1(x)-y2(x)=x^2-4*x+c has a discriminant of 0.
This happens when D=((-4)^2-4c)=0, or when c=4.
(a)
So when c=4, the two equations will barely touch, giving a single solution, or coincident roots.
(b)
when c is greater than 4, the two curves are farther apart, thus there will be no (real) solution.
(c)
when c<4, then the two curves will cross at more than one location, giving two distinct solutions.
It will be more obvious if you plot the two curves in a graphics calculator using c=3,4, and 5.
