ICE Princess25 [194]2 years ago
6 0

Answer:

There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.

For example

10:18,

15:27

Rewrite the following quadratic function in vertex form. Then, determine if it has a maximum or minimum and say what that value
alexira [117]

Discussion

1. Put brackets around the first two terms

y = (-x^2 + 6x) + 5

2. Take out the common factor of -1

y = -(x^2 - 6x) + 5

3. Inside the brackets, take 1/2 of - 6 and square it

y = -(x^2 - 6x + ( - 6 / 2)^2 )  + 5

y = -(x^2 - 6x +  (- 3)^2 )  )  + 5

y = -(x^2 - 6x + 9 ) + 5

Note: Step 3 is very long. Make sure you work your way through it

4. You have added 9 inside the brackets. <em><u>It is actually - 9. So add 9 outside to balance the equation out. </u></em> This is the key step. Make sure you understand it.

y = - (x^2 - 6x + 9) + 5 + 9

5. Express the brackets as a square.

y = - (x + 3)^2 + 14

Discussion

The equation is now in vertex form. The minus tells you that the equation is a maximum. The maximum is located at ( - 3, 14 )

A graph follows to show the results.

Explain how you determined the length of segment LM using 2-3 sentences or explain your steps used to find the value for y.
anastassius [24]
<h2>Explanation:</h2><h2 />

The question is incomplete so I'll assume the segment LM is defined by these two points:

L(4,3) \\ \\ M(5,8)

So we can find the length of the segment by using the distance formula:

d=\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2} \\ \\ \\ So, \ if \ we \ call: \\ \\ L(x_{1},y_{1}) \ and \ M(x_{2},y_{2}) \\ \\ \\ Then: \\ \\ \overline{LM}=\sqrt{(4-5)^2+(3-8)^2} \\ \\ \overline{LM}=\sqrt{(-1)^2+(-5)^2} \\ \\ \overline{LM}=\sqrt{1+25} \\ \\ \boxed{\overline{LM}=\sqrt{26}}

I will name brianliest if correct.
Black_prince [1.1K]

Answer:

C. or 3 1/4

Step-by-step explanation:

First, turn all of the amount of fruits (Grapes, Melon, and Pineapple) into an improper fraction.  

Grapes: 11/3

Melon: 9/4

Pineapple: 11/4

Then, make a common denominater for each fraction, which is 12, add all of them up. Since you know that the amount of strawberries that Maria uses is 3/8 TIMES the amount of the other fruits, so you multiply the fruits by 3/8.

Grapes: 44/12

Melon: 27/12

Pineapple: 33/12

44/12 + 27/12 + 33/12 times 3/8

= 104/12 times 3/8

= (if you simplify) 13/4 times 1/1 (1/1 = 1)

= 13/4

= 3 1/4

So, the answer is C. 3 1/4

(I hope this helped. Sorry if I was too slow.)
