Hello :
<span>g(x) = 5x² - 50x + 128
= 5(x²-10x +128/5)
= 5 (x²-10x+5²-5² +128/5)
= 5 ((x-5)² +128/5 -125/5)
y = 5 ((x-5)² - 3/5)
y= 5(x-5)² +3.....vertex form
the vertex is : (5,3)</span>

Find Number of strawberry cakes
--------------------------------------------------------------------
1 part = 24 cakes
5 parts = 24 x 5 = 120
--------------------------------------------------------------------
Find number of apple cakes
--------------------------------------------------------------------
1 part = 24 cakes
4 parts = 24 x 4 = 96
--------------------------------------------------------------------
Total number of cakes
--------------------------------------------------------------------
120 + 96 + 144 = 360

Answer:
- <u>It is a combination</u>
<u></u>
Explanation:
This is a combination because the order does not matter: the Beagle - Collie couple is the same as the Collie - Beagle couple, so it is only counted once.
The formula for combinations is:
For five diffferent dogs to be put in pairs, the number of different pairs is:
Answer:
The answer will be: C: 2<em>t </em>+ 10
Step-by-step explanation:
You can check the answer by replacing <em>t </em>with any number.
Example:
I want to find the perimeter for 3 triangles. Here's how I would write the equation.
2(3) + 10 = 6 + 10 = 16
We can check by adding all the sides for three triangles.
2 + 2 + 2 + 5 + 5 = 16
Hope this helped :)
Answer:
1728/ 125
Step-by-step explanation:
The ratio of corresponding lengths of the figures = ratio of the square root of their areas.
So ratio of lengths = 12/5.
Now volume is 3 dimensional so the ratio is the cube of the lengths
= 12^3/5^3
= 1728/ 125.
