A doctor estimates that a particular patient is losing bone density at a rate of 3% annuallythe form f(x)=ab^ x , where f(x) represents the bone density after x years ?

Answers

The question above is incomplete

Complete Question

A doctor estimates that a particular patient is losing bone density at a rate of 3% annually. The patient currently has a bone density of 1,500 kg/mg³. The doctor writes an exponential function to represent the situation. Which values should the doctor use for a and b in a function written in the form f(x) = ab^x, where f(x) represents the bone density after x years?

Answer:

a = 1500

b = 0.97

f(x) = ab^x

f(x) = 1500(0.97)^x

f(x) = 1500 × 0.97^x

Step-by-step explanation:

We are to find a and b

This question has to do with exponential decay.

This is written as

y = a(1 - r)^x

f(x) = ab^x

r = rate of exponential decay

f(x) = y

a = a

b^x = (1 - r)^x

a = current bone density of the patient = 1500kg/m³

b = (1 - r)

r = 3% = 0.03

b = (1 - 0.03)

b = 0.97

Therefore,

a = 1500

b = 0.97

Hence:

f(x) = ab^x

f(x) = 1500(0.97)^x

f(x) = 1500 × 0.97^x

Which equation represents a line that is parallel to the x-axis, is perpendicular to the y-axis, and has a slope of 0?

B.
[tex]y = \frac{5}{4} x[/tex]

C.
[tex]y = \frac{4}{5} [/tex]

D.
[tex]x = \frac{5}{4} [/tex]

Answers

Answer:

C

Step-by-step explanation:

The equation of a line parallel to the x- axis ( slope of 0 ) and perpendicular to the y- axis has equation

y = c

where c is the value of the y- coordinates the line passes through.

The only equation in this form is

y = [tex]\frac{4}{5}[/tex] → C

Answer:

8 < x < 16

Step-by-step explanation:

Consider an angle slightly less than 180 between the 4 and 12 ft sides.  The measure between the 2 end points is slightly less than the total of the two sides.  So the greatest length is 16.

Consider an angle slightly more than 0 between the 4 and 12 ft sides.  The measure between the 2 end points is slightly more than the difference between the two sides.  So the lowest length is 8.

Find the simple interest earned, to the nearest cent, for the principal, interest rate, and time.



$530, 6%, 1 year

Answers

The simple interest earned on $530 at 5.5% rate for 1 years is $31.80.

How to calculate simple interest?

The formula for simple interest is expressed mathematically as;

I = P × r × t

Where I is interest, P is principal, r is interest rate and t is time period.

Given the data in the question;

Principal P = $530Interest rate r = 6%Time period t = 1 yearInterest I = ?

First, convert the rate from percent to a decimal form

Rate r = 6%

Rate r = 6/100

Rate r = 0.06

To determine the simple interest earned, plug the given values into the simple interest formula and solve for I.

I = P × r × t

I = $530 × 0.06 × 1

I = $530 × 0.06

I = $31.80

Therefore, the simple interest accumulated after 1 years is $31.80.

What is the equation of the line that passes through the point(6,4) and has a slope of -2/3

Answers

Answer:

y=-2/3x+8

Step-by-step explanation:

first, find the y intercept, or b.

write your equation so far: y = -2/3x + b

Now substitute in your given point (6,4)

so now we got: 4 = -2/3(6) + b

which gives you: 4 = -4 + b

Now, we find b.

4 = -4 + b  

+4    +4      < isolating b...

8 = b

now put it back in..

y=-2/3x+b

write a function using the graph ​

Answers

Answer:

[tex]\displaystyle f(x)=-\frac{2}{3}(x+2)(x-3)^2[/tex]

Step-by-step explanation:

The graph corresponds to a cubic function of the form:

[tex]f(x)=a(x-p)(x-q)(x-r)[/tex]

Where p, q, and r are the zeros of f(x).

We can clearly see there are only two crossings through the x-axis. That is because one of the roots is repeated (multiple).

Thus, the roots are p=-2, q=r=3

Substituting into the function:

[tex]f(x)=a(x+2)(x-3)(x-3)[/tex]

[tex]f(x)=a(x+2)(x-3)^2[/tex]

The value of a can be found by using the y-intercept seen on the graph (0,-12):

[tex]-12=a(0+2)(0+3)^2[/tex]

Operating:

[tex]-12=18a[/tex]

Thus:

[tex]a = -12 / 18 = -2/3[/tex]

The function is now complete:

[tex]\mathbf{\displaystyle f(x)=-\frac{2}{3}(x+2)(x-3)^2}[/tex]

Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

Answer:

The points (0, 0) and (1, 20) can be used to create the line that represents the situation.

If t is the x-coordinate and r is the y-coordinate, then any point that satisfies the equation r = 20t for t > 0 can be used to graph the line. So, any two points that satisfy the equation, such as (0, 0), (1, 20), (2, 40), (3, 60), (4, 80), (5, 100), and so on, can be used to create the line that represents the situation. The line is the same in each case.
