Answer:

Step-by-step explanation:

When the mean of two numbers is the same as one of the numbers, then the other number also has that same value. This is true for any kind of mean:

arithmetic, geometric, harmonic.

The other number would be 7.

The geometric mean (m) of a and b is ...

m = √(ab)

We have ...

7 = √(7b)

49 = 7b . . . . . square both sides

7 = b . . . . . . . .divide by 7

a = b = m = 7 in this case.

If Taylor has 2 times as many nickels as quarters and they have a combined value of 245 cents, how many of each coin does he hav

Goryan [66]

Answer:

Taylor has 14 Nickels and 7 Quarters

Step-by-step explanation:

A nickel is equivalent to 5 cent while a quarter is equivalent to 25 cents.

If the number of nickels Taylor has is 2x then the number of quarters is x

Given that the total value is 245 cents,

5(2x) + 25x = 245

10x + 25x = 245

35x = 245

x = 7, 2x = 2 × 7 = 14

It means Taylor has 14 Nickels and 7 Quarters

Find and sketch the domain of the function. f(x,y)=√(4-x^2-y^2) +√(1-x^2)<br>

elena55 [62]

Answer:

Hello

Step-by-step explanation:

The domain is limited with 2 lines parallel: -1 ≤ x ≤ 1

and the disk ? (inside of a circle) of center (0,0) and radius 2

$dom\ f(x,y)=\{(x,y) \in \mathbb{R} ^2 | \ -1\leq x \leq -1\ and \ ( -\sqrt{4-x^2} \leq \ y \leq \sqrt{4-x^2}\ ) \ \}\\$
