Does anyone know what that number would be?

Does Anyone Know What That Number Would Be?

Answers

Answer 1

Step-by-step explanation:

The new c term be 49 for completing the square.

x² - 14x + 49

= x² - 2 * x * 7 + 7²

= ( x - 7) ²

Hope it will help :)

Answer 2

Answer:

49

Step-by-step explanation:

What two numbers add to the middle term and multiply to the last term? 49 doesnt fit in to 14 at all so we know that one of the factors is 7. since the middle term is -14, you would add -7 to -7 to get that. so we know the factors of the middle term are -7 and -7, so all you have to do is multiply them together. It would be positive 49.

Which correlation coefficient represents the strongest downward trend in a data set? -0.83 -0.23 0.12 0.92

Answers

Answer: -0.83

Step-by-step explanation:

A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.

-1 ≤ r ≤1

For downward trend r is negative.

For strong correlation r should be closer to 1 or -1.

From the given correlation coefficients  -0.83 is both negative and closer to -1.

Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83

The measure of two side of a triangle are given if p is the perimeter and p=18x+9y find the measure of the third side

Answers

Answer:

10x + 6y

Step-by-step explanation:

Let t = length of the third side

3x + 4y + 5x - y + t = 18x + 9y

8x + 3y + t = 18x + 9y

t = 10x + 6y

Step-by-step explanation:

So basically it's divided into 3 similar triangles and using ratios we can try to find x

long side/short side = long side/short side

(20)/(x) = (x)/(15)

[tex]x^{2}[/tex] = 300

Answer:

y = x + 5

1 would be the slope AKA m

Step-by-step explanation:

y = mx + b

mx is change of y to the change in x.

m is the slope

As you can see in the problem above, everytime y moves up 1, x moves to the right 1.

b is the y intercept - where is y when x is at 0?

This will help you find the slope of future problems hopefully. :)

The other person is correct

Answer:

[tex]y = 2(2) {}^{x} [/tex]

Step-by-step explanation:

It ask us to create a exponential function. A exponential function is represented by a equation like this

[tex]y = ab {}^{x} [/tex]

where a is the vertical stretch, b is the constant rate of growth, and x is the nth exponet.

Using the point 0,2

we can plug that in to find a part of the equation above.

let x=0 and y=2

[tex]2 = ab {}^{0} [/tex]

[tex]b {}^{0} = 1[/tex]

[tex]2 = a \times 1[/tex]

[tex]a = 2[/tex]

Let update the equation now since a equal 2

[tex]y = 2b {}^{x} [/tex]

Now let use point 2,8 to find the b value

let x=2 and y=8

[tex]8 = 2b {}^{2} [/tex]

Divide both sides by 2

[tex]4 = {b}^{2} [/tex]

take the sqr root of 4

[tex]b = 2[/tex]

Let update the equation

[tex]y = 2(2) {}^{x} [/tex]
