Answer:

r=3 ft

Step-by-step explanation:

it is similarity of two triangles

one

perpendicular side=10 ft

base=10/2=5 ft

second

perpendicular side=10-4=6 ft

Base r=?

$\frac{r}{5}=\frac{6}{10}\\r= \frac{6}{10} \times 5=3~ft$

1. The amount of extension in an elastic spring varies directly as the weight hung on it. If a weight of 150 gm produces an exte

gregori [183]

Answer:

900 g

Step-by-step explanation:

let e be extension and w be weight

given e varies directly as w then the equation relating them is

e = kw ← k is the constant of variation

to find k use the condition w = 150 , e = 2.9 , then

2.9 = 150k ( divide both sides by 150 )

$\frac{2.9}{150}$ = k , that is

k = $\frac{29}{1500}$

e = $\frac{29}{1500}$ w ← equation of variation

when e = 17.4 , then

17.4 = $\frac{29}{1500}$ w ( multiply both sides by 1500 )

26100 = 29w ( divide both sides by 29 )

900 = w

What is the effect on the graph of the function f(x) =5x when f(x) is replaced with f(x) + 9?

Nimfa-mama [501]

Answer:

When we add 9 to the function we are shifting the function up 9 units.

Step-by-step explanation:

If it were added inside the function, it woulds shift it left or right.

But since it is outside the function, we will shift it up or down

When we add 9 to the function we are shifting the function up 9 units.
