Answer:

The 3rd option Summation(4^i-4)

Step-by-step explanation:

Summation(4^i-4)

When i = 1

4^I-4 = 4^1-4 = 4^-3 = 1/64

When i = 2

4^i-4 = 4^2-4 = 4^-2 = 1/16

When i = 3

4^i-4 = 4^3-4 = 4^-1 = 1/4

When i = 4

4^i-4 = 4^4-4 = 4^0 = 1

When i = 5

4^i-4 = 4^5-4 = 4^1 = 4

Answer:

\sum _{i=1}^54^{i-4}

Step-by-step explanation:

a_{1} \\ = First term

In this case, our first term is \frac{1}{64}

The ratio of all of the adjacent terms is 4

a_{1} \\ = 4^1^-^4

a_{1}=\frac{1}{64}

~Hope this helps!~

Write each expression as an algebraic​ (nontrigonometric) expression in​ u, u > 0.
max2010maxim [7]

Answer:

\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)=\frac{20\sqrt{u^2-100}}{u^2}\text{ where } u>0

Step-by-step explanation:

We want to write the trignometric expression:

\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)\text{ where } u>0

As an algebraic equation.

First, we can focus on the inner expression. Let θ equal the expression:

\displaystyle \theta=\sec^{-1}\left(\frac{u}{10}\right)

Take the secant of both sides:

\displaystyle \sec(\theta)=\frac{u}{10}

Since secant is the ratio of the hypotenuse side to the adjacent side, this means that the opposite side is:

\displaystyle o=\sqrt{u^2-10^2}=\sqrt{u^2-100}

By substitutition:

\displaystyle= \sin(2\theta)

Using an double-angle identity:

=2\sin(\theta)\cos(\theta)

We know that the opposite side is √(u² -100), the adjacent side is 10, and the hypotenuse is u. Therefore:

\displaystyle =2\left(\frac{\sqrt{u^2-100}}{u}\right)\left(\frac{10}{u}\right)

Simplify. Therefore:

\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)=\frac{20\sqrt{u^2-100}}{u^2}\text{ where } u>0

You are a landlord, and your tenant complains that you are in violation of the ADA because your wheelchair ramp is too steep. An
Savatey [412]

Answer:

  Not justified

Step-by-step explanation:

ADA requirements are for a slope of 1 in 12 or less, an 8.3% grade, or an angle of 4.8° (actually, 4.764° when rounded to 3 decimal places). The ramp angle found by the assessor is compliant.

  The tenant complaint does not seem justified.
