Answer:

h = 2.25 m

Step-by-step explanation:

<u><em>Given:</em></u>

Speed = v = 12 ft/sec

Acceleration due to gravity = g = 32 ft/sec²

<u><em>Required:</em></u>

Height = h = ?

<u><em>Formula:</em></u>

v = \sqrt{2gh}

<u><em>Solution:</em></u>

For h, the formula will be:

=> h = \frac{v^2}{2g}

=> h = \frac{(12)^2}{2(32)}

=> h = \frac{144}{64}

=> h = 2.25 m

Write an explicit furmula for the question below <br> 40 points!!!!!!!!!!!!!
Usimov [2.4K]

Answer:

aₙ = a₁ . 5⁽ⁿ⁻¹⁾

Step-by-step explanation:

The first term in the sequence is a₁ = 6.

a₂ = 30. a₃ = 150.

We see that each consecutive term is multiplies by 5 to arrive at the next term.

That is: a₂ = 30 = a₁ . $ 5^{2 - 1}  = 5 $ = 6.5 = 30.

Similarly, a₃ = 150 = 6 $ \times $ $ 5^{3 - 1} = 5^2 = 25 $

Generalizing this, we have:

aₙ = a₁ . $ 5^{n - 1} $

This is called the recursive formula of the sequence.

In which graph does y vary directly as x? It’s not C, I got it wrong.
Ludmilka [50]
Hello there!

Based on my research and information, I really believe that (option a) would actually be your correct answer. I believe this basically because sense the letter k is always constant, we would only divide this by what it is, which is y, and from these, your solution would always look like your (option a). Please inform if correct.

Happy to help!

What is the axis of symmetry of -2x^2+12x-3
Zanzabum

Answer:

x = 3

Step-by-step explanation:

The formula for the axis of symmetry is x = -b/(2a).

Here, a = -2 and b = 12, so the axis of symmetry is

       -12

x = --------- = 3                 =>           x = 3

      2(-2)

Ooh ok these are fun. So these triangles are similar, meaning they are in proportion. In triangle LMN, line LM is 21. To find the corresponding line on the other triangle, we need to find the corresponding letters in the names. Because L and M are the first two letters, we need to use the first two letter s in the other name, so FG. Line FG is 9, so our first proportion is 9/21
