the Function h(x)=1/2(x+3)^2+2. How is the graph of h(x) translated from the parent graph of a qaudratic function, f(x)=x^2
Kay [80]

Answer:

Translation of h(x) is 2 unit down, 3 unit right and vertical stretch by 2

Step-by-step explanation:

Given function: h(x)=\dfrac{1}{2}(x+3)^2+2

Parent function: f(x)=x^2

It is parabolic function.

h(x)=\dfrac{1}{2}(x+3)^2+2

Shift 2 unit down

g(x)=\dfrac{1}{2}(x+3)^2+2-2

g(x)=\dfrac{1}{2}(x+3)^2

Shift 3 unit right

g(x)=\dfrac{1}{2}(x+3-3)^2

g(x)=\dfrac{1}{2}x^2

Vertical stretch by factor 2

g(x)=2\cdot dfrac{1}{2}x^2

g(x)=x^2=f(x)

So, Translation of h(x) is 2 unit down, 3 unit right and vertical stretch by 2

Suppose Cotangent (theta) = StartFraction 5 Over 12 EndFraction, where Pi less-than theta less-than StartFraction 3 pi Over 2 En
Agata [3.3K]

Answer:

Sin theta = 12/13

Step-by-step explanation:

From the question;

Cot theta = 5/12

Kindly recall;

Cot theta = 1/ tan theta

Hence, tan theta = 12/5

Mathematically

tan theta= opposite/adjacent

to get hypotenuse, we will use Pythagoras’ theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides

let hypotenuse be h

h^2 = 12^2 + 5^2

h^2 = 144 + 25

h^2 = 169

h = √169

h = 13

But sine theta = opposite/ hypotenuse = 12/13
