What is a transformation of a point?

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

A polygon on a coordinate grid was transformed using the rule given below.

(x, y) ⇒ (x - 4, y - 3)

The new coordinate of the coordinate (1, 2) will be

(x, y) ⇒ (1 - 4, 2 - 3)

(x, y) ⇒ (-3, -1)

The new coordinate of the coordinate (2, 3) will be

(x, y) ⇒ (2 - 4, 3 - 3)

(x, y) ⇒ (-2, 0)

The new coordinate of the coordinate (3, 1) will be

(x, y) ⇒ (3 - 4, 1 - 3)

(x, y) ⇒ (-1, -2)

The new coordinate of the triangle will be (-3, -1), (-2, 0), and (-1, -2).

Find 3 consecutive numbers who sum is 216

Answers

Answer:

the three consecutive numbers be 71, 72 and 73 respectively

Step-by-step explanation:

The computation of the 3 consecutive numbers is shown below:

Let us assume the three consecutive numbers be x , x+1 and x + 2

Now their sum is

x + x + 1 + x+ 2 = 216

3x + 3 = 216

3x = 216 -3

3 = 213

x = 71

x + 1 = 71 + 1 = 72

x + 2 = 71 + 2 = 73

Hence, the three consecutive numbers be 71, 72 and 73 respectively

Answers

Complete Question

Environmental engineers are using data collected by weather data centers to learn how climate affects the sea ice. Of 526  ice melt ponds studied in a certain​ region, 84 were classified as having​ "first-year ice". The researchers estimated that about 16% of melt ponds in the region have​ first-year ice.​ Estimate, with​ 90% confidence, the percentage of all​ ice-melt ponds in the region that have​ first-year ice. Give a practical interpretation of the results.

Answer:

The 90% confidence interval is [tex] 0.1337   <  p < 0.1857   [/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  526  

   The  number that were classified to having a 'first-year ice ' is  k =  84

    The population proportion is  p  = 0.16

Generally the sample proportion is mathematically represented as

         [tex]\^ p = \frac{k}{ n }[/tex]

=>      [tex]\^ p = \frac{ 84}{ 526 }[/tex]

=>      [tex]\^ p = 0.1597[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{ p (1-  p)}{n} } [/tex]

=>   [tex]E =  1.645 * \sqrt{\frac{0.16 (1- 0.16)}{ 526} } [/tex]

=>  [tex]E =  0.026 [/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>   [tex]0.1597  -0.026  <  p < 0.1597  -0.026  [/tex]

=>   [tex] 0.1337   <  p < 0.1857   [/tex]

Write the equation of the line that passes through the given point and is parallel to the given line.
Keep all fractions in improper form

Answers

(Note: this answer is assuming that the equation has to be put in slope-intercept format.)

Answer:

[tex]y = \frac{1}{2} x - \frac{5}{2}[/tex]

Step-by-step explanation:

1) Let's use the point-slope formula to determine what the answer would be. To do that though, we would need two things: the slope and a point that the equation would cross through. We already have the point it would cross through, (-3,-4), based on the given information. So, in the next step, let's find the slope.

2) We know that the slope has to be parallel to the given line, [tex]y = \frac{1}{2}x - 8[/tex]. Remember that slopes that are parallel have the same slope - so, let's simply take the slope from the given equation. Since it's already in slope-intercept form, we know that the slope then must be [tex]\frac{1}{2}[/tex].

3) Finally, let's put the slope we found and the x and y values from (-3, -4) into the point-slope formula and solve:

[tex](y- (-4)) = \frac{1}{2} (x - (-3))\\y + 4 = \frac{1}{2} (x + 3))\\y + 4 = \frac{1}{2}x+ \frac{3}{2} \\y = \frac{1}{2}x + \frac{3}{2} - 4\\y = \frac{1}{2}x + \frac{3}{2} - \frac{8}{2} \\y = \frac{1}{2}x - \frac{5}{2}[/tex]

Therefore, [tex]y = \frac{1}{2}x - \frac{5}{2}[/tex] is our answer. If you have any questions, please do not hesitate to ask!

le Gianna just started a running plan where she runs 20 miles the first week and then increases the number of miles she runs by 5% each week. If she keeps up this plan for 17 weeks, how many total miles would Gianna have run, to the nearest whole number?​

Answers

Answer:

Gianna ran 40 miles over the course of 17 weeks.

Step-by-step explanation:

20 miles in the first week.

5% increase each week.

17 weeks.

5% * 20 = 1

1 mile increase each week.

17 * 1 = 17

17 mile increase over the course of 17 weeks.

20 + 17 = 37

37 miles over the course of 17 weeks.

Round 37 to the nearest whole number.

37 ^ 40

The number of total miles that would Gianna have run, to the nearest whole number should be considered as the 40.

Calculation of the number of miles:

Since

20 miles in the first week.

5% increase each week.

And, then there is 17 weeks

So, if 5% of 20 = 1

So here the total miles be like

= 20 + 17

= 37

= 40

hence, The number of total miles that would Gianna have run, to the nearest whole number should be considered as the 40.

A scuba diver has a rope connecting the dive boat to an anchor on the ocean floor. The rope is 13ft long. The water is 5ft deep. How far is the anchor from a point directly below the boat?

Answers

Answer:

The anchor is 12 feet far from the point directly below the boat.

Step-by-step explanation:

Given that:

Length of rope connecting the dive boat to an anchor = 13 feet

Depth of water = 5 feet

Here,

The rope connecting the dive boat to the anchor will serve as hypotenuse of a right angle triangle, depth of water will be the height of triangle and distance from anchor to point directly below the boat will be base of triangle.

Using Pythagorean theorem;

[tex]a^2+b^2=c^2[/tex]

a = 5 , c = 13

[tex](5)^2+b^2=(13)^2\\25+b^2=169\\b^2=169-25\\b^2=144[/tex]

Taking square root on both sides

[tex]\sqrt{b^2} =\sqrt{144}\\b=12[/tex]

Hence,

The anchor is 12 feet far from the point directly below the boat.
