Answer:

x = 5

Step-by-step explanation:

since the work is already done for you, all you have to do is divide 20 by 4, which gives you 5.

you can also check this answer by multiplying 4 by 5, which would give you 20, further proving the answer.

n the month of June, the temperature in Johannesburg, South Africa, varies over the day in a periodic way that can be modeled ap

Sveta_85 [38]

T = - 7.5 Cos π/12( t - 4 ) + 10.5 varies over the day in a periodic way that can be modeled approximately by a trigonometric function.

<h3>What is trigonometric function?</h3>

The trigonometric functions are actual functions that relate a right-angled triangle's angle to side length ratios. They are extensively employed in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many more.

<h3>According to the given information :</h3>

Maximum temp. = 18 degree Celsius

Minimum temp. = 3 degree Celsius

The half way between 10 am and 10 pm is 4 am

Temperature data changes throughout the year can be modeled using the sine and cosine functions. The following form of equation can be used to model these data:

T = A cos B(t - C) + D, where A,B,C,D, are constants, T is the temperature in °C and t is the hour (1–24)

A = amplitude = (Tmax - Tmin)/2

A = (3 - 18)/2 = - 15/2 = -7.5

B = 2π/24 = π/12

C = units translated to the right

C = 4

D = ymin + amplitude = units translated up

D = 7.5 + 3 = 10.5

The formula of the trigonometric function that models the temperature T in Johannesburg t hours after midnight we be

T = - 7.5 Cos π/12( t - 4 ) + 10.5

When an object falls due to gravity on Earth, the acceleration is 9.8 m/s. A student drops a rock

Aneli [31]

Answer:

29.4 m/s

Step-by-step explanation:

Use v = at with a = 9.8 m/s^2 and t = 3.00 sec

v = 9.8 * 3.00 = 29.4 m/s

<h3>What is the fair value of an investment?</h3>

The fair value of an investment is the current value and not the historical cost when the investment was made.

Fair value refers to the intrinsic worth of an asset or security.

<h3>Data and Calculations:</h3>
