A variable is any characteristics, number, or quantity that can be measured or counted.
A unit is measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

romanna [79]
(2x+6)/10 = (x+6)/8
10(x+6) = 8(2x+6)
10x + 60 = 16x  + 48
6x = 12
x = 2

so
AE = 2(2) +6
AE = 4 + 6
AE = 10

Write the equation of the graph shown below in factored form. the graph starts at the bottom left and continues up through the x
netineya [11]

For each x intercept the corresponding factor can be deduced. For x intercepts given at 1,2,3 , the equation can be written as

y= (x-1) (x-2) (x-3)

Because x=1 therefore x-1=0 , similarly x=2 , x-2=0 and , x=3 , x-3=0

or

y= x²+2x-3 (x-3)

or

y= x³+2x²-3x-3x²-6x+9

y= x³-x²-9x+9

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
