Randy's swimming coach kept track of his average 50-meter lap times during the first 3 weeks of training. How much greater was the percent of change from Week 1 to Week 2 than from Week 2 to Week 3? Round to the nearest tenth of a percent.

The true statements are: (A), (D), (E) and (F).

Statement A is true. A triangle is said to be isosceles if its two sides are of equal length. Considering the triangle STU, the sides ST and TU are the radius of the same circle centered at T and hence of same length. So triangle STU is isosceles.

Statement B is false. In triangle STU, ST and TU being radii of circle T, are equal. But the third side SU is not a radius of any circle in the diagram and so not equal to ST and TU. Since three sides are not of same length, triangle STU is not an equilateral triangle.

Statement C is false. In Triangle STU two sides are composed of a single radii and not of two radii. The third side is not composed of radii.

Statement D is true. In triangle STU, two sides are radii of circle T but the third side, segment SU, is not a radius of any circle shown in the diagram.

Statement E is true. In triangle VWZ, each side is composed of 2 radii which are of same length. Hence three sides are equal and so it is an equilateral triangle.

Statement F is true. Each side of triangle VWZ is composed of two radii that have the same length.

Answer:

Step-by-step explanation:

The value of x is 8.366, y is 4.582 and z is 5.477.

Using Pythagoras theorem in both Triangle as

Triangle 1:

H² = P² + B²

z²= y² + 3²

z² = y² + 9

Triangle 2:

x² = y² + 7²

x² = y² + 49

and, x² = z² - 9 + 49

x² = z² + 40.............(1)

Now, In big Triangle

x² + z² = 10²

x² + z² = 100

Now, from equation (1) we get

z² + 40 + z² = 100

2z² = 60

z² = 30

z = 5.477

and, x²= 30+40 = 70

x= 8.366

and, y²= z² - 9

y² = 21

y= 4.582

The statements are not valid syllogisms.

The term syllogism has to do with the reasoning in which a premise must lead to a conclusion. In other words, the conclusion must logically follow from the premise that has been given.

Let us now see if the statements follows the laws of syllogism;

Statement 1 - If you interview for a job, then you wear a suit.

Statement 2 - If you interview for a job, then you will update your resume.

Looking at these statements it is easy to see that they are not valid syllogism. This is because, not every job requires you to wear a suit for interview. You could have a CV that does not need to be updated and still use it for an interview.

The value of x from the figure shown is 2.19

According to the Pythagoras theorem, the square of the hypotenuse is equivalent to the sum of the square of other two sides.

From the given diagram, the expression below is true;

6^2 = 3^2 + (3+x)^2

Determine the value of x

36 = 9 + (9+6x + x^2)

36 = 18 +6x+x^2

x^2 + 6x - 18 = 0

On factorizing, the value of x is expressed as;

x = -3 + 3√3
x = -3 + 3(1.732)

x = 2.19
