The parabola y-- (x – 3)2 + 6 has its focus at (3, 1). Determine and state the equation of the directrix.
Answer: you got to Find the focus of a parabola given its equation. If you have the equation of a parabola in vertex form , then the vertex is at and the focus is . Notice that here we are working with a parabola with a vertical axis of symmetry, so the -coordinate of the focus is the same as the -coordinate of the vertex.

A company makes 100 bags.
41 of the bags have buttons but no zips.
32 of the bags have zips but no buttons.
22 of the bags have neither zips nor buttons.
How many bags have zips on them?
Answer:
37
Step-by-step explanation:
Bags that zips and no button = 32
Bags that have both zips and bags = 100-(41+32+22) = 5
Total bags that have zipz = 32+5 = 37

Step-by-step explanation:
You have 24 coins valued at $3.00. Some of the coins are dimes and some are quarters. Find the number of each coin that you have.
Answer:
10 Quarters and 5 dimes
Step-by-step explanation:
10 Quarters = $2.50
5 dime = $0.50
Answer:
20 dimes and 4 quarters
Step-by-step explanation:
So, a dime is 10 cents and a quarter is 25
So, let's say you have x dimes and y quarters
X+Y=24 (total amount of coins)
Also,
10x+25y= 300 (cents)
I just put the 3 dollars into cents
Now, you have a system of equations and we should solve it:
X+y=24 ----x=24-y
10x+25y=300
So substitute x in the 2nd equation
10(24-y)+25y=300
240-10y+25y=300
240+15y=300
15y=60
y=4
Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20
So, 4 quarters and 20 dimes
Check:
20 dimes=2 dollars
4 quarters= 1 dollar
correct

Answer:
A.)555 in.^2
Step-by-step explanation:
When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.
You can cut that trapezoid into two triangles and one rectangle.
Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work).
We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.
44 - 30 = 14
14/2 = 7
Now that we filled in the information not listed, we can finally solve:
The base of one triangle is 7 inches, and the height is 15 inches.
Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).
But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).
7 x 15 = 105
The area of both triangles combined: 105 in.^2
Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).
15 x 30 = 450
The area of the rectangle: 450 in.^2
Now, the final step. Addition. All you need to do is add up all the sums, and you're done.
450 + 105 = 555
The area of entire figure: 555 in.^2
NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)
