Where is the vertex of the parabola?
RideAnS [48]

Answer:

ABOVE the x-axis

Step-by-step explanation:

Please use "^" to denote exponentiation:  y = x^2 + 2x + 3

To find the vertex, we must complete the square of y = x^2 + 2x + 3, so that we have an equivalent equation in the form f(x) = (x - h)^2 + k.

Starting with  y = x^2 + 2x + 3,

we identify the coefficient of x (which is 2), take half of that (which gives

us 1),  add 1 and then subtract 1, between "2x" and "3":

y = x^2 + 2x + 1 - 1 + 3

Now rewrite x^2 + 2x + 1 as (x + 1)^2:

y = (x + 1)^2 - 1 + 3, or y = (x + 1)^2 + 2.  Comparing this to f(x) = (x - h)^2 + k, we see that h = 1 and k = 2.  This tells us that the vertex of this parabola is at (h, k):  (1, 2), which is ABOVE the x-axis.

Write your own word problem and share it with the group. Then translate your problem into its resulting math equation. What step
Ainat [17]

Step-by-step explanation:

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example:

A certain number is divided by half, the result is added to itself to give 6, what is the number?

Solution:

- Let the number be x

- Divide x by half:

In word problem, extra caution is to be taken, as misinterpretation can be very chaotic. Dividing a number by 2, is totally different from dividing the number by half.

4 divided by 2 is 4÷2 = 2

4 divided by half is 4÷½ = 4×2/1 = 8

2 and 8 are different, reason to be cautious.

So dividing x by half, we have:

x ÷ 1/2 = x × 2/1 = 2x.

- Now, what we have is

2x + x = 6

Solving this equation, we can obtain the value of x.

2x + x = 6

3x = 6

Dividing both sides by 3

3x/3 = 6/3

x = 2.

Therefore, the solution to the word problem is x = 2.

HELP......................................
djyliett [7]

Answer:

The equation's result: 32,000 (Rounded)

Goal: Find the closest or equivalent result in another expression

Step-by-step explanation:

<h3>A)</h3>

(1.5^{15})/(0.7^{12})\\(1.5^{15})/(0.7^{12}) = (437.894)/(0.7^{12})\\437.894/(0.014)\\31636.79

How we got to 31,636 was by dividing from left to right.

Remember: When dividing decimals, it's like multiplying whole numbers in a way. The number(the quotient, also) ends up bigger instead of being smaller like when dividing whole numbers. If you multiply decimals, they(the product) end up smaller.

Therefore, A is the correct answer.
