Step-by-step explanation:

Answer:

2.3

Step-by-step explanation:

In this case we are going to use the 'Babylonian Method' to get the square root of any positive number.

We must set an error for the final result. Say, smaller than 0.01. In other words we will try to find the square root value with at least 1 correct decimal places.

Step 1:

Divide the number (5.29) by 2 to get the first guess for the square root .

First guess = 5.29/2 = 2.645.

Step 2:

Divide 5.29 by the previous result. d = 5.29/2.645 = 2.

Average this value (d) with that of step 1: (2 + 2.645)/2 = 2.3225 (new guess).

Error = new guess - previous value = 2.645 - 2.3225 = 0.3225.

0.3225 > 0.01. As error > accuracy, we repeat this step again.

Step 3:

Divide 5.29 by the previous result. d = 5.29/2.3225 = 2.2777179763.

Average this value (d) with that of step 2: (2.2777179763 + 2.3225)/2 = 2.3001089882 (new guess).

Error = new guess - previous value = 2.3225 - 2.3001089882 = 0.0223910118.

0.0223910118 > 0.01. As error > accuracy, we repeat this step again.

Step 4:

Divide 5.29 by the previous result. d = 5.29/2.3001089882 = 2.299891017.

Average this value (d) with that of step 3: (2.299891017 + 2.3001089882)/2 = 2.3000000026 (new guess).

Error = new guess - previous value = 2.3001089882 - 2.3000000026 = 0.0001089856.

0.0001089856 <= 0.01. As error <= accuracy, we stop the iterations and use 2.3000000026 as the square root.

So, we can say that the square root of 5.29 is 2.3 with an error smaller than 0.01 (in fact the error is 0.0001089856). this means that the first 3 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math.sqrt(5.29)' is 2.3.

Note: There are other ways to calculate square roots. This is only one of them.

Normal:

The square root of 5.29 is defined as the only positive real number such that, multiplied by itself, it is equal to 2.3.

The square root of 5.29 can be written as (5.29)1/2. So,

(5.29)1/2 = (2.3 × 2.3)1/2

(5.29)1/2 = [(2.3)2]1/2

(5.29)1/2 = (2.3)2/2

(5.29)1/2 = (2.3)1

Thus,

√5.29 = 2.3

Answer:

20 laps

The length of TU in the right triangle is  156.15 m.

The area of the rectangle is 12335.85 m²

The length of GH in the right triangle is 182.33 m

The area of the triangle is 8934.17 m²

Right angle triangle are triangle that has one of its angle as 90 degrees. The sides of the triangle can be found using Pythagoras theorem. Therefore, using Pythagoras theorem,

TU² = 175² - 79²

TU² = 30625 - 6241

TU² = 24384

TU = √24384

TU = 156.153770368

TU = 156.15 m

area of rectangle = lw

area of rectangle =  156.15 × 79

area of rectangle =  12335.85 m²

GH² = 207² - 98²

GH² = 33245

GH = √33245

GH = 182.33211456

GH = 182.33 m

Area of the triangle = 1 /  2 bh

Area of the triangle = 1 /  2 × 98 × 182.33

Area of the triangle = 17868.34 / 2

[tex]\frac{1}{14}[/tex]

Step-by-step explanation:

[tex]\frac{1}{4} + \frac{23}{28} - 1 = ?[/tex]

First off, let's change everything to a common denominator. This will allow us to add the fractions!

To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.

Let's change the first fraction into a number with a denominator of 28!

[tex]\frac{1}{4} * \frac{7}{7} = \frac{7}{28}[/tex]

[tex]\frac{7}{7}[/tex] = 1. Multiplying a number by one doesn't change its value.

The second fraction, [tex]\frac{23}{28}[/tex], already has a denominator of 28, so we don't have to do anything with it.

Now to the third number, -1:

[tex]-1 = -\frac{1}{1} * \frac{28}{28} = -\frac{28}{28}[/tex]

Now, let's add them all up!

[tex]\frac{7}{28} + \frac{23}{28} - \frac{28}{28} = \frac{7 + 23 - 28}{28} = \frac{2}{28}[/tex]

One last step, to simplify:

[tex]\frac{2}{28} = \frac{1}{14}[/tex]

Step-by-step explanation:

arithmetic sequence : every new item of the sequence is created by adding a constant term to the previous item - in this case 195.

a1 = 3087 (that's our starting value)

a2 = a1 + 195

a3 = a2 + 195 = a1 + 2×195

an = a1 + (n-1)×195

a)

when he is 45 years old, that is 20 years (and 20 annual increments) plus to our starting value.

so, n = 1+20 = 21

a21 = a1 + 20×195 = 3087 + 20×195 = 6987

so, when he is 45 years old, his monthly salary will be RM6,987

b)

how many years (= how big is n) until he gets 8937 ?

8937 = a1 + (n-1)×195 = 3087 + (n-1)×195 =

= 3087 + n×195 - 195 = 2892 + n×195

6045 = n×195

n = 6045/195 = 31

so, a31 = 8937

and that means, he has to work 30 additional years (31 minus the starting level 1) to earn monthly RM8,937.

that means he will be 25+30 = 55 years old.
