Identify the zeros for the function and sketch a graph. y=x(x-2)(x+3)

Mathematics

damaskus [11]3 years ago
5 0

The product is equal to zero if one of the factors is equal to zero.

Therefore:

y=x(x-2)(x+3)\\\\x(x-2)(x+3)=0\iff x=0\ \vee\ x-2=0\ \vee\ x+3=0\\\\\boxed{x=0\ \vee\ x=2\ \vee\ x=-3}

Can someone help me with this math problem? I have no idea where to begin.<br> Solve: |y + 8| ≥ 3
lorasvet [3.4K]
Since y+8 is positive, you don't have to find the absolute value since the absolute value is y+8. all you have to do is find a number that makes the statement true for y. the symbol between next to the 3 asks for a number that is greater or equal to 3. So your answer would be

≥-5

Fernando needs a total of 6
Fantom [35]

Answer:

Equation: 6f = 5

Result: 6/5 cup of flour is needed for each batch of bread

Step-by-step explanation:

Given

6 cups of flour makes 5 batches of bread

Required

His much flour is needed for each batch.

Let f represent a cup of flour.

The statement "total of 6 cups of flour to make 5 batches of bread." means that

f + f + f + f + f + f = 5 batches of bread

f * 6 = 5

6f = 5

The above equation will give the number of cup needed for 1 batch of bread.

To do that, we simply divide both sides by 5

6f/5 = 5/5

6f/5 = 1

Hence,

The equation is represented by: 6f = 5

And the result is: 6/5 cup of flour is needed for each batch of bread

Can someone please help me I really need help please help me thank you

Hey there! :)

Answer:

SA = 144 cm².

Step-by-step explanation:

Find the surface area by calculating the areas of each of the lateral sides and bases:

In this instance, the bases are triangles, so the formula A = 1/2(bh) will be used:

Bases:

A = 1/2(bh)

A = 1/2(4·3)

A = 1/2(12)

A = 6 cm².

There are two bases, so:

6 × 2 = 12 cm²

Find the areas of the lateral sides using A = l × w:

5 × 11 = 55 cm²

4 × 11 = 44 cm²

3 × 11 = 33 cm²

Add up all of the areas:

12 + 55 + 44 + 33 = 144 cm².
