Since you're starting off with a bone density of 1,500 kg/mg3, that should be your a value. Anything in the form of abb^{x} will be arranged as follows: Your a value is your starting value, whereas the b value is the rate at which your starting value will change every x years. In this case, that would mean that f(x)=1,500*0.97^x. A=1,500 and B=0.97

Answer:

a = 1500 and b = 0.97

Step-by-step explanation:

A patient is losing bone density at a rate of 3% annually.

Present bone density of the bones is 1500 kg/mg³

Doctor writes an exponential function to represent the situation.

The exponential function will be f(x) = a(b)^{x} which is an explicit formula for exponential sequence.

Here a = initial bone density of the patient

b = common ratio of the sequence formed in x years

x = time in years

Then the values of a and b in the formula will be

a = 1500

b = (1 - 0.03) = 0.97

and the function will be f(x)=1500(0.97)^{x}

Therefore, a = 1500 and b = 0.97 will be the answer.

2x=-95-1

2x=-96

x=-96/2

x=-48

x=-48

x=-48x+1=-48+1=-47

-48 and -47 are the two consecutive integers

Find the 14th term of the geometric sequence 5 -10 20
Anna [14]

Answer:

  a14 = -40,960

Step-by-step explanation:

The sequence has a first term of 5 and a common ratio of -10/5 = -2, so the n-th term is given by ...

  an = a1·r^(n-1)

  an = 5·(-2)^(n-1)

The 14th term is then ...

  a14 = 5·(-2)^(14-1) = -5·2^13 = -5·8192

  a14 = -40,960

Please help! Find the equation of the line and I will mark as brainliest IF answer is right. <3
Hoochie [10]
<h3>Answer:  y = (3/4)x + 13/4</h3>

This is the same as writing y = 0.75x + 3.25

slope is 3/4 = 0.75

y intercept is 13/4 = 3.25

==========================================================

Explanation:

One marked point on this line is (-3,1)

Another point is at (1,4)

Let's find the slope of the line through these two points.

m = (y2-y1)/(x2-x1)

m = (4-1)/(1-(-3))

m = (4-1)/(1+3)

m = 3/4

m = 0.75

Now let's use point slope form to find the equation of the line

y - y1 = m(x - x1)

y - 1 = 0.75(x - (-3))

y - 1 = 0.75(x + 3)

y - 1 = 0.75x + 2.25

y = 0.75x + 2.25 + 1

y = 0.75x + 3.25

If you wanted, you can convert those decimal values to fraction form

  • 0.75 = 75/100 = 3/4
  • 3.25 = 325/100 = 13/4

That means the equation

y = 0.75x + 3.25

is the same as

y = (3/4)x + 13/4
