Answer:

14.5 =x

Step-by-step explanation:

Since this is a right triangle we can use trig functions

sin theta = opposite side/ hypotenuse

sin A = BC / AB

sin 65 = x /16

Multiply each side by 16

16 sin 65 =x

14.50092459 =x

14.5 =x

Please help, Describe the transformation of the graph of the parent function y = √x for the function y = √x + 7 + 5.
Setler79 [48]

Answer:

C. Up.

Step-by-step explanation:

We have been given that the parent function y=\sqrt{x} is transformed to the function y=\sqrt{x+7}+5. We are asked to describe the given transformation.

Let us recall the transformation rules.

f(x+a)=\text{Graph shifted to left by a units},

f(x-a)=\text{Graph shifted to right by a units},

f(x)+a=\text{Graph shifted upwards by a units},

f(x)-a=\text{Graph shifted downwards by a units}.

Upon comparing our transformed function with the parent function, we can see that the graph is shifted to left by 7 units and upwards by 5 units.

Therefore the correct choice is option C.

The rectangle below has an area of x^2-7x+10x square meters and a width of x-5x meters. What expression represents the length of
sergey [27]

Answer:

The area of a rectangle is:

\sf A=lw

Plug in what we know:

\sf x^2-7x+10=l(x-5)

Factor the left side:

\sf (x-2)(x-5)=l(x-5)

Divide (x - 5) to both sides:

\sf l=\boxed{\sf x-2}

So the length is x - 2 meters.
