Answer:

The value of x is 55.6 unit.

Option (A) is correct .

Step-by-step explanation:

Now by using the trigonometric identity

sin \theta = \frac{Perpendicular}{Hypotenuse}

\theta = 20^{\circ}

Perpendicular = 19

Hypotenuse = x

Put in the identity

sin\ 20^{\circ}= \frac{19}{x}

sin 20° = 0.342

Put in the above equation

x= \frac{19}{0.342}

x = 55.6

Therefore the value of x is 55.6 unit.

Option (A) is correct .

Answer:

Step-by-step explanation:

We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 5655

r = 1.4% = 1.4/100 = 0.14,

a) Therefore, the equation that estimates the population t years after 2010 is

A = 5655(1 + 0.14)^t

A = 5655(1.14)^t

b) in 2022, the number of years t = 2022 - 2010 = 12

Therefore,

A = 5655(1.14)^12

A = 27245

Write the edge of the cube in terms of its volume​
Elanso [62]

Answer:

Step-by-step explanation:

The formula for the volume is given by

(side)3=volume

Since we have the volume, we must take the cube root of the volume to find the length of any one side (since it is a cube, all of the sides are equal).

(side)3−−−−−−√3=side=volume−−−−−−√3

Plugging in 216 for the volume, we end up with

side=6 cm
