Bob and Mark talk about their families. Bob says he has 3 kids, the product of their ages is 72. He gives another clue: the sum
DaniilM [7]
I have answered this question before. 

Given:
Bob has three kids whose ages has the product of 72. I will only be able to give you a set of 3 numbers to represent the ages. Had the sum of the ages been given, the specific ages would be provided.

I just did a prime factorization of 72.

72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 =   9
  9 ÷ 3 =   3
  3 ÷ 3 =   1

1 x 2 x 2 x 2 x 3 x 3 = 72   ⇒ 2³ x 3²

There are a lot of possible combinations, here are a few.

1 x 8 x   9 = 72      ⇒ 1 + 8 + 9 = 18
1 x 4 x 18 = 72      ⇒ 1 + 4 + 18 = 23
<span>2 x 4 x   9 = 72      ⇒ 2 + 4 + 9 = 15</span>

WHERE DO THE NUMBERS GO? help!!!!!!
Marat540 [252]

Answer:

Other: \frac{3}{4} , 0.25

Whole Numbers: -20, -6

Natural Numbers: 532, 10, 0, \frac{6}{2}

Step-by-step explanation:

Natural numbers have to be positive whole numbers such as 10 and 0

Whole numbers are similar, but you can have negative numbers here. You just can't put fractions in there.

The 3rd section is a little odd, Integers don't use fractions or decimals, same as whole numbers. The fractions and decimal numbers would go outside of that section.

Extra note: \frac{6}{2} might be a tricky one because it is in fraction form but it is also written as 3. This means it is a natural number. The reason numbers such as \frac{3}{4}  and 0.25 are not natural numbers is because they cannot be put as whole numbers.

Find an ordered pair to represent a in the equation<br> a=2b+c if b=(6,3) and c=(-4,8)
zaharov [31]

Answer:

The ordered pair to represent a in the equation a=2b+c if b=(6,3) and c=(-4,8) is: a=(8,14)

Step-by-step explanation:

b=(6,3)

c=(-4,8)

a=2b+c

Replacing b and c in the equation above:

a=2(6,3)+(-4,8)

Multiplying:

a=(2*6,2*3)+(-4,8)

a=(12,6)+(-4,8)

Adding:

a=(12+(-4),6+8)

a=(12-4,14)

a=(8,14)

Please help!! If y = sin x, then dy/dx =
Citrus2011 [14]

Answer:

the answer is option B

Step-by-step explanation:

To find dy/dx the equation here is

first multipled by derivative of second + second multipled by derivative of first

y = x*sinx

dy/dx = x * derivative of sinx + sinx * derivative of x

derivative of x with respect to x is 1

derivative of sinx with respect to x is cosx

therefore

dy/dx = x * cosx + sinx * 1

= x * cosx + sinx
