Answer:

I believe its true

Step-by-step explanation:

You have to find circumference of a circle. Pi comes here because of its ratio. 2 and r comes because it equals the diameter. So pi times 2 times r is basically circumference over diameter times diameter which gives circumference.

Two sides of a right triangle have the lengths 4 and 5. What is the product of the possible lengths of the third side? Express t

marishachu [46]

Answer:

19.2

Step-by-step explanation:

1st Case:

4 and 5 are legs of the right triangle.

Using the pythagorean therom: a^2+b^2=c^2

We can say that 4^2+5^2=x^2

16+25=x^2

41=x^2

x=√41

√41 is about 6.4

x=6.4

2nd Case

5 is the hypotenuse of the right triangle and 4 is the legs.

Using the pythagorean therom: a^2+b^2=c^2

We can say that 4^2+x^2=5^2

16+x^2=25

x^2=9

x=3

Final Step

We need to multiply the two possible lengths for x. So for case 1 the length of x was 6.4 and for case two the length was 3. 6.4*3=19.2

The water temperature at the beach was 75°F every day for the past 2 weeks. The water temperature at the beach will be 75°F today.

Step-by-step explanation:

Inductive reasoning is a logical reason in which multiple premises which are believed to be true or found true most of the time, are combined to form a particular conclusion.

Therefore, the second and the fourth are the examples of inductive reasoning.
