The base of a ladder is 25 meters due west of a burning building. If the angle of elevation of the ladder is 51°, how long is th

Andru [333]

Distance from the building where the fireman is standing = 25 m due yo the west pointed angle of elevation of the ladder = 51 degrees You then aquire the length of the ladder equals...
x ThenCos 51 degree = 25/x0.6293
= 25/xx = 25/0.6293 = 39.72 meters≈40 meters from the above deduction, so the correct answer is D, because it is the closest, and that it is correct.

Ksivusya [100]

Answer:

See below

Step-by-step explanation:

$\bf \mu(x)$ is the average

$\bf \mu(x)=\frac{4*0+33*1+39*2+12*3+8*4+4*5}{100}=\frac{199}{100}=1.99\;radios/week$

$\bf \sigma^2(x)$ is the variance

$\bf \sigma^2(x)=\frac{4*(0-1.99)^2+33*(1-1.99)^2+39*(2-1.99)^2+12*(3-1.99)^2+8*(4-1.99)^2+4*(5-1.99)^2}{100}=\frac{128.99}{100}=1.2899$

$\bf \sigma(x)$ is the standard deviation

$\bf \sigma(x)=\sqrt{variance}$

$\bf \sigma(x)=\sqrt{1.2899}=1.1357\;radios/week$

How many solutions does the equation sin(4x)= 3/4?

MAVERICK [17]

$sin(4x)= \dfrac{3}{4}$

$4x=sin^-^1( \dfrac{3}{4}), \pi -sin^-^1( \dfrac{3}{4})$

<span>Since sin is a periodic function, add the periodicity.
</span>
$4x=2\pi n+sin^-^1 ( \dfrac{3}{4} ) ,nEZ 

$

$4x=2\pi n-sin^-^1 ( \dfrac{3}{4} ) ,nEZ$

$x= \dfrac{2\pi n+sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$

$x= \dfrac{2\pi n+ \pi -sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$
