<h3>Daylight time June trough to December</h3>

Question Parameters:

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days).

Generally the equation for the Amplitude and vertical shift is mathematically given as

$A=\frac{Max+min}{2}\\\\A=\frac{10+14}{2}$

A=2

vertical shift = $\frac{Max-min}{2}$

vertical shift = $\frac{14-10}{2}$

vertical shift =1

Therefore, the time is given as

$t=\frac{2\pi}{b}$

Where

$b=\pi/6\\\\t=\frac{2\pi}{\pi/6}$

Hence,The graph will have a solution

y=12sin(6t-\pi)+2

Does the following equation determine y to be a function of x? y square=x+3

Phantasy [73]

Answer:

∴ y² = x + 3 is not a function

Step-by-step explanation:

* Lets explain how to solve the problem

- The definition of the function is every input (x) has only one

output (y)

- Ex:

# y = x + 1 where x ∈ R , is a function because every x has only

one value of y

# y² = x where x ∈ R , is not a function because y = ±√x, then one

x has two values of y

* Lets solve the problem

∵ y² = x + 3

- Find y by taking √ for both sides

∴ y = ± √(x + 3)

- That means y = √(x + 3) and y = - √(x + 3)

∵ (x + 3) must be greater than or equal zero because there is no

square root for negative number

∴ x + 3 ≥ 0 ⇒ subtract 3 from both sides

∴ x ≥ -3

∴ x must be any number greater than or equal -3

- Let x = 0

∴ y = √(0 + 3) = √3 and y = - √(0 + 3) = -√3

∴ x = 0 has two values of y ⇒ y = √3 and y = -√3

- Any value of x greater than or equal 3 will have two values of y

∴ y² = x + 3 is not a function

Kelly drew a circle with a diameter of 8cm Paige drew a circle with a radius of 3cm approximately how much larger is the area of

nlexa [21]

Answer:

15.7

Step-by-step explanation:

d = 2r

d = 8 thus r = 4

area (kelly) = 4 x4 x $\pi$ = 16 $\pi$

area (paige) = 3 x 3 x $\pi$ = 9 $\pi$

difference = 16 $\pi$ - 9 $\pi$ = 5 $\pi$ = 15.7
