The predicted height for someone with a femur length of 55 cm is of:

175 cm.

The linear function in this problem is obtained using the point-slope format, which is given as follows:

y - y' = m(x - x').

In which:

From the image given at the end of the answer, two points on the line are given as follows:

(35, 139) and (40, 151).

Given two points the slope is calculated as the change in y divided by the change in x, hence:

m = (151 - 139)/(40 - 35) = 2.4.

Considering the first point, the definition of the line is given as follows:

y - 139 = 2.4(x - 40).

The predicted height for someone with a femur length of 55 cm is y when x = 55, hence:

y - 139 = 2.4(x - 40).

y - 139 = 2.4(55 - 40)

y = 175 cm.

Answer: the correct anserw is A.!

Step-by-step explanation:

the slope of the line is zero, as change in y cordintae is 0.

What is the slope of line?

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1). x1 and y1 are represented by the first point's coordinates. The second points are located at x2, y2, and their locations. Whichever point you choose to classify as the first and which as the second doesn't matter.

In the given line in the graph, the change in y coordinate is 0.

We know that slope = change in y / change in x

As the change in y coordinate is 0.

The slope of the line will be zero.

Hence, the slope of the line is zero.

1) The annual decay rate of the exponential function is given as follows: 12.94%.

2) The number of people who started the rumor is of 10.

3) The number of people who will have heard the rumor after 3 days is given as follows: 96 people.

For item 1, the format of the exponential function is given as follows:

A(t) = A(0)(1 - r)^t.

In which r represents the annual decay rate.

The half-life of Radium-228 is 5.75 years, hence:

A(5.75) = 0.5A(0).

Thus the annual decay rate of the exponential function is given as follows:

0.5A(0) = A(0)(1 - r)^5.

(1 - r)^5 = 0.5

Applying the fifth root to both sides:

1 - r = (0.5)^(1/5)

1 - r = 0.8706

r = 1 - 0.8706

r = 0.1294 = 12.94%.

Then for items 2 and 3 we just obtain the numeric values.

The number of people who started the rumor is N(0), hence:

N(0) = 600/(1 + 59e^(-0.7 x 0)) = 600/60 = 10 people.

The number of people who heart the rumor after three days is N(3), hence:

N(3) = 700/(1 + 69e^(-0.8 x 3)) = 96 people.

The solution is

A) The vertical asymptote of the function f ( x ) is = -3

B) The holes in the graph of f ( x ) = ( 0 , 6 )

C) The horizontal asymptote of the function f ( x ) is = 6

What are Asymptotes?

An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote. When graphing functions, asymptotes are typically not required

There are 3 types of asymptotes

Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k. Horizontal Asymptote is when the function f(x) is tending to zero

Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero

Slanting asymptote (Oblique asymptote) - It is a slanting line and hence its equation is of the form y = mx + b

Given data ,

Let the function be f ( x ) = ( 6x² + 6x - 36 ) / ( x² + 3x )

A)

Now , to find the vertical asymptote

To find the vertical asymptote of a rational function, we simplify it first to lowest terms, set its denominator equal to zero, and then solve for x values

So , when x² + 3x = 0

x ( x + 3 ) = 0

So , x + 3 = 0

x = 0 is a hole in the graph

x = -3 is the vertical asymptote

B) The hole in the graph is ( 0 , 6 )

C)

Now , to find the horizontal asymptote

If both the polynomials have the same degree, divide the coefficients of the leading terms

So , 6x² and x² are the polynomials having the same degree

So , the coefficients are 6 and 1

y = (leading coefficient of numerator) / (leading coefficient of denominator)

y = 6 is the horizontal asymptote

Hence ,

A) The vertical asymptote of the function f ( x ) is = -3

B) The holes in the graph of f ( x ) = ( 0 , 6 )

C) The horizontal asymptote of the function f ( x ) is = 6

⇒ dx = [tex]\sqrt{2}[/tex] du

= [tex]\frac{2^{\frac{5}{2}} }{2u^2+2}du[/tex]

On simplifying

= [tex]2^{\frac{3}{2} }[/tex][tex]\int\limits\frac{1}{u^2+1} \, du[/tex] .........(1)

Now  [tex]\int\limits\frac{1}{u^2+1} \, du[/tex] = [tex]tan^{-1} (u)[/tex]

Substitute this value in equation (1)

= [tex]2^{\frac{3}{2} }tan^{-1}(u)[/tex]

Substitute the value of u here

Step-by-step explanation:

calculate the slope m through the 2 points using the slope formula and equate to - 5

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (7, 3 ) and (x₂, y₂ ) = (s, - 7 )

What is the definition of the limit?

A point or level beyond which something does not or may not extend or pass.

We have to check for continuity by evaluating 2ˣ and -x² - 4x + 1

at the breakpoint x = 0

2⁰ is 1 and -x² - 4x + 1 is also 1,

So these two functions approach the same value as x approaches 0.

Now do the same thing with

-x² - 4x + 1  and (1/2)x + 3 at x = 2;

The first comes out to -11 and the second to 4.  

Thus, this function is not continuous at x = 2.  

We must reject statement A.

for D we have as x increases without bound,

(1/2)x  + 3

also increases without bound.  

Therefore the statement D is true statement.

Statement C is  False,

because the quadratic has a maximum -x² - 4x + 1 has a maximum at

x = -b/[2a],

x = -(-4) / [-2],

x = -2

Answer:

slope=3/2 y- intercept=9

Answer:

Slope: 3/2

y-intercept: 9

Step-by-step explanation:

Slope-Intercept Form is given in the form: [tex]y = mx+b[/tex], where [tex]m = \text{slope and }b=\text{y-intercept}[/tex].

So it's very convenient to have a linear equation in this form to identify the slope and y-intercept. To get into this form, we simply need to isolate the y-value.

We start with the initial equation:

[tex]-3x+2y=18[/tex]

The first step to isolating "y" is to move any terms on the same side as the "y" variable to the other side. So let's move the 3x term to the other side, by adding 3x to both sides.

[tex](-3x+3x)+2y=18+3x\implies 2y=18+3x[/tex]

From here, the only thing that is with the "y" variable is the coefficient. The [tex]2y[/tex] is the same thing as: [tex]2\ *\ y[/tex]. We want to get rid of the 2, which we do by dividing by 2, to cancel out the multiplication by 2.

[tex]\frac{2y}{2} = \frac{18 + 3x}{2} \implies y = \frac{18 + 3x}{2}[/tex]

Now from here we want to distribute the division by 2 as such:

[tex]y = \frac{18 + 3x}{2} \implies y = \frac{3}{2}x + \frac{18}{2} \implies y= \frac{3}{2}x + 9[/tex]

So now we have the equation:

[tex]y= \frac{3}{2}x + 9[/tex]

this is in the slope-intercept form:

[tex]y=mx+b[/tex]

in this form the coefficient of x is the slope, so 3/2 is the slope. The constant is the y-intercept, so 9 is the y-intercept.
