The circumference of Fis 120 cm. What is the length of DË (the minor arc)?

Afina-wow [57]

Answer:

15cm

Step-by-step explanation:

Let x be the arc circumference.

The circumference of a circle usually subtends to 360°, that is, one complete revolution is 360°.

#Given the arc angle as 45° and the circumference as 120cm, the arc circumference can be obtained as:

#Apply proportions to find x:

$360\textdegree=120cm\\45\textdegree=x\\\\x=(120/360)\times 45\\\\x=15cm$

Hence, the arc circumference is 15cm

8. Suppose y varies directly as x. If y = -4 when x = 32, find x when ys -0.

Nata [24]

Answer:

$x=0$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

in this problem

For x=32, y=-4

Find the value of the constant of proportionality k

$k=y/x$

substitute

$k=-\frac{4}{32}$

simplify

$k=-\frac{1}{8}$

The linear equation is

$y=-\frac{1}{8}x$

Find x when the value of y=0

Remember that

In a proportional relationship the line passes through the origin

If y=0

then

the value of x must be equal to zero

therefore

$x=0$
