Use the definitions for the sets given below to determine whether each statement is true or false:
ella [17]

Answer:

(a) false

(b) true

(c) true

(d) true

(e) false

(f) true

(g) false

(h) true

(i) true

Step-by-step explanation:

(a) 15 ⊂ A, since 15 is not a set, but an element, we cannot say of an element to be subset of a set. False

(b) {15} ⊂ A The subset {15} is a subset of A, since every element of {15}, that is 15, belongs to A.

15 ∈ {15} and 15 ∈ { x ∈ Z: x is an integer multiple of 3 } 15 is  an integer multiple of 3. since 15/3=5. True

(c)∅ ⊂ A

∅ is a subset of any set. True

(d) A ⊆ A

A is a subset of itself. True

(e)∅ ∈ B

∅ is not an element, it is a subset, so it does not belong to any set. False

(f)A is an infinite set.

Yes, there are infinite integers multiple of 3. True

(g)B is a finite set.

No, there are infinite integers that are perfect squares. False

(h)|E| = 3

The number of elements that belong to E are 3. True

(i)|E| = |F|

The number of elements that belong to F are 3. So is the number of elements of E. True

Since the area of the circle is I the area of the square, the
Dovator [93]

Answer:

(b)

V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}] or V_2 = \frac{1}{3}\pi r^2h

Step-by-step explanation:

Given

Ratio = \frac{\pi}{4}

See attachment for complete question

Required

Determine the volume of the cone

The volume of a square pyramid is:

V = \frac{a^2h}{3}

Where

a = base dimension

From the attachment, the base dimension of the square pyramid is 2r.

So:

a = 2r

The volume becomes;

V = \frac{(2r)^2h}{3}

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.

So, we have:

V_2  = Ratio * V

V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]

V_2 = \frac{\pi}{4} * \frac{(2r)^2h}{3}

Open bracket;

V_2 = \frac{\pi}{4} * \frac{4r^2h}{3}

Cancel out 4

V_2 = \pi * \frac{r^2h}{3}

The above can be written as:

V_2 = \frac{1}{3} * \pi r^2h

V_2 = \frac{1}{3}\pi r^2h

So, we have:

V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]

or

V_2 = \frac{1}{3}\pi r^2h

What is 8.57x10-⁴ in standered form ?
marusya05 [52]

Kaleerain5,

In order to get your answer you must remember that if the exponent is negative move to the left and if the exponent is positive you have to move to the right.

  • 8.57 \times 10^{-4}
  • The exponent is negative so move to the left:
  • 8. = .8 = .08 = .008 = .0008
  • = .000857

Therefore your answer is ".000857."

Hope this helps!
