Gretchen computed the geometric mean of two numbers. One of the
alina1380 [7]

9514 1404 393

Answer:

  7

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.

The sum of three consecutive integers is greater than 66. What is the smallest possible product of the largest and smallest of t
AysviL [449]

Answer:

528

Step-by-step explanation:

So naturally at first sight for this question we would think -->

Oh 3 consecutive integers = 66 --> 66/3 = 22 (n-1), (n+1) so --> 21, 22, and 23.

But no. At second look it is the sum of 3 consecutive integers is greater than 66. So we find the next possible pair since it says smallest possible product.

We get the set (22, 23, 24). => Multiply the least and greatest integers together respectively 22 and 24 which amounts to => 528

And thus, we have out answer of 528

Hope this helps!

PLEASEEE HELP<br> Questions 4 and 5
Ilya [14]

Answer:

  • Given and explained below.

question 4

using sine rule:

\sf sinx = \frac{opp}{hyp}

\sf sinx = \frac{11}{13}

\sf x = sin^{-1}(\frac{11}{13} )

\sf x = 57.8

question 5

using cosine rule:

\sf cosx =\frac{adj}{hyp}

\sf cos(31) =\frac{x}{17}

\sf cos(31)*17 =x

\sf x = 14.6
