<h3>Answer:  false</h3>

Work Shown:

s = false

p = true

r = false

-p = false, which is the opposite of statement p

s or -p = false or false = false

The result of an 'or' operation is false only when both parts are false; otherwise, it is true

(s or -p) or r = false or false = false

(s or -p) or r = false

Pavlova-9 [17]

Answer:  22 meters

<u>Step-by-step explanation:</u>

Draw a picture of a right triangle and label the height as 30 meters and the hypotenuse as 37 meters.  Use the Pythagorean Theorem to find the base (the length of the shadow).

a² + b² = c²

x² + 30² = 37²

x²          = 37² - 30²

x²          = 1369 - 900

x²          = 469

√x²       = √469

        x = 21.656

        x ≈ 22

An arithmetic sequence has this recursive formula:
horsena [70]

Answer:

\text{\bf{C.}}\quad a_n=4+(n-1)(-7)

Step-by-step explanation:

An arithmetic sequence that is described by the explicit formula ...

  a_n=a_1+(n-1)d

can also be described by the recursive formula ...

  \left \{\begin{array}{l}a_1=\text{(first term)}&a_n=a_{n-1}+d&\end{array}\right.

Matching parts of the formulas, we see that a1 = 4, d = -7. Putting these values into the explicit formula gives ...

a_n=4+(n-1)(-7)
