The set of points that form a hyperbola are inversely related.

Two variables, A and B are inversely proportional if A is equal to a constant, K, divided by B, i.e. A = K/ B. That, of course is equivalent that B = K/A, which means that if the two variables are inversely related, A in inverselty proportional to A and B is inversely proportional to A, with the same inverse proportion constat.

Then, if you have two points of the hyperpola, you can find the constant of proportion K, by using K = A*B.

Once you have the constat K, you can find all the points of the hyperbola by plugging any value of B' to determine A, by doing A' = K / B'.

If you know that the points 4 and 12 are inversely related, you find the constant k , by doing k = 4-12 = 48, and now you can generate the points of the parabola by doing>

A = 48/B or B = A/48

So, using A = 48/B, you can find all the values of A for any value of B and those points form a hyperboly.

B              A
1              48/1 = 48
2              48/2 = 24
3              48/3 = 16
4              48/4 = 12

-1                -48
-2                -24
-3                -16
-4                -12

Draw those points in a coordinate system and you will see a hyperbola.

Answer:

The unique relationships that conic sections represent between two variables can be then seen as examples of direct and inverse relationships [y = k over x]. Hyperbolas, for example, are relationships where the two related variables are related inversely.

Hope this helps!!

Megan’s TV had a base price of $189 and the sales tax was 6.88%. Over the next four years, the TV consumed an average of $0.06 o
Leni [432]

Answer:

Step-by-step explanation:

price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00

4 years = 3×365 days + 366 days = 1461 days

cost of electricity = 1461 days × $0.06/day = $87.66

lifetime cost = purchase price + electricity + repairs

= $202.00 + $87.66 + 2·$29

= $347.66

A physician wants to develop criteria for determining whether a patient's pulse rate is atypical, and she wants to determine whe
valkas [14]

Answer:

a) 66.1 < μ < 82.7

b) 71.9 < μ < 97.7

c) D. No, because the two confidence intervals overlap, we cannot conclude that the two population means are different.

Step-by-step explanation:

Confidence interval is given by the formula

M±t×(\frac{s}{\sqrt{N} }) where

  • M is the sample mean
  • t is the corresponding t value for 95 confidence level
  • s is the sample standard deviation
  • N is the sample size

<u>a. Construct a 95% confidence interval estimate of the mean pulse rate for males.</u>

For men:

M=74.4 t=2.262 s=11.6207 N=10 then confidence interval is:

74.4±2.262×(\frac{11.6207}{\sqrt{10 } }) ≈ 74.4±8.3

<u>b. Construct a 95% confidence interval estimate of the mean pulse rate for females.</u>

For women:

M=84.8 t=2.262 s=18.0488 N=10 then confidence interval is:

84.8±2.262×(\frac{18.0488 }{\sqrt{10 } }) ≈ 84.8±12.9

<u>c. Compare the preceding results. Can we conclude that the population means for males and females are different?</u>

Difference of Population means for males and females are not statistically significant, since confidence intervals overlap.

Slick Slack is a downloadable app that can be used to automatically generate excuses for being late to work based on the weather
Greeley [361]

Answer:

(x_1,y_1) = (1,5840)

(x_2,y_2) = (2,13090)

y = 1812.5x + 4027.5

y_0 = 4027.5 --- y intercept

Step-by-step explanation:

Given:

x = weeks; y = copies

The right parameters are:

After 1 week, 5840 copies were downloaded

After 5 weeks, 13090 copies were downloaded

So, the (x,y) forms are:

(x_1,y_1) = (1,5840)

(x_2,y_2) = (5,13090)

Next, we calculate the slope (m) using:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{13090 - 5840}{5 - 1}

m = \frac{7250}{4}

m = 1812.5

The equation is then calculated using:

y = m(x - x_1) + y_1

y = 1812.5(x - 1) + 5840

y = 1812.5x - 1812.5 + 5840

y = 1812.5x + 4027.5

To calculate the y intercept, substitute 0 for x

y_0 = 1812.5*0 + 4027.5

y_0 = 0 + 4027.5

y_0 = 4027.5

What is the 15th term in the sequence...pt.1​
Blababa [14]
This is a geometric progression

so first term a = 3

common ratio r = 12/3 or 48/12 = 4

so in GP n term is given as

t_{n} \: = a {r}^{n - 1} \\ so \: \\ t_{1} \: = a {r}^{1 - 1} = 3 \times {r}^{0} = 3 \times 1 = 3 \\ t_{2} \: = a {r}^{2 - 1} = 3 \times {r}^{1} = 3 \times {4}^{1} = 3 \times 4 = 12 \\ t_{15} \: = a {r}^{15 - 1} = 3 \times {r}^{14} = 3 \times {4}^{14} = 3 \times 268435456 = 805306368 \\

so answer is 805306368
