A pole that is 3.2 m tall casts a shadow that is 1.45 m long. At the same time, a nearby building casts a shadow that is 36.5 m

Usimov [2.4K]

To solve this, use proportions. The height of the pole corresponds to the height of the building; the shadows are corresponding: 3.1/x =1/45.5
3.1 times 45.5=1x
141.05=x
The building is 141 meters tall

Given h(x) =1/2 x + 4 find h(-4) + 2.

Lynna [10]

Hi there! :)

$\large\boxed{h(-4) + 2 = 4}$

h(x) = 1/2x + 4

Substitute in -4 for "x" to solve for h(-4):

h(-4) = 1/2(-4) + 4

h(-4) = -2 + 4

h(-4) = 2

Since we are solving for h(-4) + 2, add:

2 + 2 = 4.

slavikrds [6]

Answer:

$g(5x)=0$

Step-by-step explanation:

Given that $g(x)=4$

From the graph when $x=-2 \ then \ g(x)=4$

Hence $5x=-10$

Now from the graph

$g(-10)=0$
