After Jeremy runs across the width of the building, he must run down a ramp to the next building. Use the following portion of t

sp2606 [1]

Answer:

$b.\ cos 70 =\dfrac{4}x$ is the correct answer.

Step-by-step explanation:

First of all, let us label the diagram as shown in the attached figure.

OR = 20'

QS = 16'

$\triangle OPQ$ is the right angled triangle that we get.

$\angle P=90^\circ$

$\angle O =70^\circ$

From the given figure symmetry, we can clearly see that:

Side OP = OR - QS

OP = 20 - 16 = 4'

Now, let us use trigonometric identity of cosine in $\triangle OPQ$ .

$cos\theta = \dfrac{Base}{Hypotenuse}$

$cosO= \dfrac{OP}{OQ}\\\Rightarrow cos70^\circ= \dfrac{4}{OQ}$

Let the distance of ramp, OQ = x'

So, the above ratio becomes:

$cos70^\circ= \dfrac{4}{x}$

So, the correct answer is:

$b.\ cos 70 =\dfrac{4}x$

The price of gasoline rose from $1.54 to $3.85.

Pavel [41]

Answer:

Step-by-step explanation:

dollar amount of increase = $3.85 - $1.54 = $2.31

percentage increase = (amount of increase)/(original price) = $2.31/$1.54 = 1.5 = 150%

The question is in the picture.

Nuetrik [128]

Answer:

x = 7 $\sqrt{3}$

Triangle area formula: base * height * 1/2

We are given:

Base - 14 cm

Height - x

Using the pythagorean theroem (a^2 + b^2 = c^2) we can figure out the height.

We are given:

Side a - 14 / 2 = 7 cm

Side b - the height (x)

Side c - 14 (it's an equilateral triangle)

Now, substitute the given values:

7^2 + x^2 = 14^2

49 + x^2 = 196

x^2 = 147

x = $\sqrt{147}$

x = 7 $\sqrt{3}$

Given f(x)=arctan(2x), find f’(x) in simplest form

Lostsunrise [7]

Answer:

Step-by-step explanation:

$f(x)=tan^{-1} 2x\\let f(x)=y\\y=tan^{-1}2x\\tan y=2x\\diff. w.r.t.x\\sec^2y(\frac{dy}{dx} )=2\\\frac{dy}{dx} =\frac{2}{sec^2 y} =\frac{2}{1+tan^2y} =\frac{2}{1+(2x)^2} \\f'(x)=\frac{2}{1+4x^2}$
