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

Answers

Answer:

Step-by-step explanation:

Pythagorean theorem,

Base² + altitude² = hypotenuse²

x² + 3² = 6²

x² + 9 = 36

     x² = 27

x = √27

Answer:

D) x=sq rt 27

Step-by-step explanation:

using the Pythagorean theorem

6^2=3^2+x^2

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

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

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]

Answers

Answer:

1

[tex]\frac{1}{1} =1[/tex]

therefore the slope is 1

plz mark me brainliest. :)

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. :)

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
