Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?

Oxana [17]

Answer:

D. $h(x)=-3x+4$

Step-by-step explanation:

we are given

$f(x)=3x$

Firstly, it is reflected over x-axis

we know that for reflection about x-axis , we can replace y as -y

we get

$g(x)=-f(x)$

$g(x)=-3x$

now, it is vertical shift up by 4 units

so, we can add 4 to y-value

we get

$h(x)=g(x)+4$

$h(x)=-3x+4$

The flagpole in front of VHS 50 feet tall. The angle of elevation from the end of its shadow to the top of the flagpole is 46°.

mamaluj [8]

Answer:

The length of the shadow is 48.28 feet.

Step-by-step explanation:

The flagpole at its shadow form a 46, 44, 90 triangle.

Let AB be the flagpole. AC is the shadow.

Let's use the sine law to calculate AC.

$\frac{AC}{sin(44)}=\frac{50}{sin(46)}\\AC=\sin(44)*\frac{50}{sin(46)}AC=48.28$
