Answer:

The value of function at x = 2 is 8.

Step-by-step explanation:

Given : Function $f(x)=2x^2+5\sqrt{x-2}$

We have to find the value of given function at x = 2 , that is f(2)

Consider the given function $f(x)=2x^2+5\sqrt{x-2}$

To find the value f(2) put x = 2 in given function ,

We have,

$f(2)=2(2)^2+5\sqrt{2-2}$

Simplify, we have,

$f(2)=8+5\sqrt{0}$

Simplify further, we have,

$f(2)=8$

Thus, the value of function at x = 2 is 8.

Find the equation of a line that passes through the given points (-6,-5) and (6,-13)

NeTakaya

Answer:

y+5=-3/4(x+6)

or in slope intercept

y= -3/4x-38/4

Step-by-step explanation:

To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-5--13}{-6-6}=\frac{-5+13}{-6+-6}=\frac{8}{-12}=\frac{-3}{4}$

Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y--5)=-3/4(x--6)

y+5=-3/4(x+6)

y+5=-3/4x-18/4

y=-3/4x-18/4-20/4

y= -3/4x-38/4

A graph has a constant of proportionality of 2.54. Let y represent centimeters and x represent inches. What is the unit rate of

Helga [31]

Answer: 2.54 is the rate of the given equation.

Step-by-step explanation:

Let x is the independent variable and y is the dependent variable.

Since, By the definition of proportionality,

y = k x

Where k is the constant of proportionality.

And, Here k = 2.54

Thus, the equation of line is,

y = 2.54 x

since, rate of the equation is the slope of the line.

And, the general equation of line

y = m x +c

Where, m is the slope of the line.

By comparing the equation of line y = 2.54 x with this.

The slope of the line = 2.54

Therefore, 2.54 is the rate of the given equation.

If log(base4)x=2.5 and log(base Y)125=-3/2, find the numerical value of x/y, in simplest form.

Naya [18.7K]

X = (2^2)^(2.5)
x = 2^(2 * 2.5) 
x = 2^5 
x = 32
y^(-3/2) = 125
y^(-3) = 125^2 
y^(-3) = (5^3)^2 
y^(-3) = (5^2)^3 
y^(-3) = 25^3 
y = 25^(-1) 
y = 1/25 

x/y => 
32 / (1/25) => 
32 * 25 => 
800 is the simplest form of above
