Answer:

Jaylen was 16 years old. She's the oldest.

Step-by-step explanation:

16  Jaylen

15  sibling 1

14  sibling 2

13  sibling 3

12 sibling 4

11  sibling 5

10  sibling 6

____________

91  Total

My thinking was that I started out dividing 91 by 7. That came out 13. So I knew the oldest one had to be older than 13.

How is a greater number a factor of a smaller number?
Eduardwww [97]

Explanation:

It depends on the definition of "factor" that you use.

One dictionary defines "factor" to be ...

  "a number or quantity that when multiplied with another produces a given number or expression"

In that sense, 7 can be a factor of 3, because 7 × (3/7) = 3.

___

Often we use the term "factor" when we mean "integer divisor", or "positive integer divisor". Using this last definition, the only factors of 3 are 1 and 3.

Other times, we use the term "factor" to mean "prime factor." By this definition, the only factor of 3 is 3 itself.

Determine if the given functions are even, odd or neither. f(x) = -2x2 - 7 and g(x) = 2x2 + 3
Anettt [7]
Answer:

It's odd.

Explanation:

A function is odd when <span><span>f<span>(−x)</span></span>=−<span>f<span>(x)</span></span></span>

<span><span>f<span>(−x)</span></span>=6<span><span>(−x)</span>3</span>−2<span>(−x)</span></span>

<span>=−6<span>x3</span>+2x</span>

<span>=−<span>(6<span>x3</span>−2x)</span></span>

<span>=−<span>f<span>(x)</span></span></span>

Thus, the function is odd.

If a function is odd, then it is symmetric over the x-axis.

Find the surface area of the cylinder in terms of pi.<br><br> Height = 8 in<br> Diameter = 4in
irga5000 [103]
1) the area of the "side" of the cylinder is A1= pi (4 in).
2) the total area of the circular ends of the cyl. is A2 = 2 pi (2 in)^2 (since the radius of the cyl. is 2 in).

The desired total surface area is A = A1 + A2.  Keep "pi;" do not substitute a numerical value for "pi."
