What is the solution to……………………ASAP

Mathematics
1 answer:
leonid [27]3 years ago
5 0

Answer:

first option

Step-by-step explanation:

Using the rules of logarithms

log x - log y = log (\frac{x}{y} )

logx^{n} ⇔ n log x

ln e = 1

Given

4 + 5e^{x+2} = 11 ( subtract 4 from both sides )

5e^{x+2} = 7 ( divide both sides by 5 )

e^{x+2} = \frac{7}{5} ( take ln of both sides )

ln e^{x+2} = ln (\frac{7}{5} )

(x + 2) lne = ln (\frac{7}{5} )

x + 2 = ln (\frac{7}{5} ) ( subtract 2 from both sides )

x = ln(\frac{7}{5} ) - 2

An opaque cylindrical tank with an open top has a diameter of 3.25 m and is completely filled with water. When the afternoon Sun
kicyunya [14]

Answer:

10.69

Step-by-step explanation:

We must first know that the angle of refraction is given by the following equation:

n_water * sin (A_water) = n_air * sin (A_air)

where n is the refractive index, for water it is 1.33 and for air it is 1.

The angle (A) in the air is 22.8 °, and that of the water is unknown.

Replacing these values we have to:

1.33 * sin (A_water) = 1 * 0.387

sin (A_water) = 1 * 0.387 / 1.33

A_water = arc sin (0.2907) = 16.9 °

now for the tank depth:

h = D / tan (A_water)

D = 3.25

Replacing

h = 3.25 / tan 16.9 °

h = 10.69

Therefore the depth is 10.69 meters.
