First, put your polynomial in standard form(ax²+bx+c=0). Then plug the a,b and c for x=(-b+-√b²-4ac)÷2a. As a result, you can either get one, two or no real answers.
Answer:60.58
Step-by-step explanation:add the first numbers 64.67 take that from 125.25 and u got 60.58
(-2,3) (3,0)
find slope
m= 0-3/(3+2) = -3/5
point slope is y-y1=m (x-x1)
point is (3,0) and m=-3/5
plug and chug
y-0=-3/5(x-3)
y=-3/5x+9/5
hope that helps
The answer is 3.
A period is the length that it takes the graph to repeat in behavior. You'll notice that every 3 units, it hits the axis and repeats the same pattern.
Answer:
Add 7 black beads
Step-by-step explanation:
Since we can only change the number of black beads, decide how many black beads you will add based on how many white beads there are.
There are three white beads in the picture.
Total beads we will have (<em>b</em> meaning black) b : 3
Ratio black : white beads 3 : 1
Use the common ratio, which is a number that both sides of the original ratio multiply by to get to the new ratio.
Find common ratio by dividing total by ratio white beads: 3/1 = 3
Multiply ratio black beads by common ratio. 3 X 3 = 9
<u>We need 9 black beads in total</u>.
Check answer
9 : 3 Both sides divisible by 3; reduce ratio
= 3 : 1 Correct ratio
There will be a total of 9 black beads, but we already have 2 black beads:
(9 total) - (2 original) = (7 to add)
Therefore we need to add 7 black beads.
