Answer:D. 36 m

Step-by-step explanation: Use the Pythagorean Theorem, which is a^2 + b^2 = c^2 to find the missing side. C is the hypotenuse. Plug in the numbers.

15^2 + b^2 = 39^2

Simplify.

225 + b^2 = 1521

Subtract 225 from each side.

b^2 = 1296

Square root each side to isolate b.

b = 36

The height of the support beam is 36 m.

Which describes the type of sequence...pt.1

Dimas [21]

Answer:

neither arithmetic nor geometric

Step-by-step explanation:

The given sequence is

$99,89.9,78.8,68.7,...$

$89.9-99=-9.1$

$78.8-89.9=-11.1$

The differences are not the same so this cannot be an arithmetic sequence.

$\frac{89.9}{99}=\frac{899}{990}$

$\frac{78.8}{89.9}=\frac{788}{899}$

The ratios are not the same so it can also not be geometric.

The sequence is neither arithmetic nor geometric.
