Find the arc length of the partial circle..

Mathematics
1 answer:
Gala2k [10]4 years ago
5 0

Answer:

The arc length of the partial circle is 6\pi\ units

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

In this problem we have a 3/4 of a circle

so

the circumference is equal to

C=(\frac{3}{4})2\pi r

C=\frac{3}{2}\pi r

we have

r=4\ units

substitute

C=\frac{3}{2}\pi (4)

C=6\pi\ units

A man purchased a car selling for RM12,750 by making instalment payments. If he was charged 4% based on the reducing balance and
a_sh-v [17]

Answer:

48 months

Step-by-step explanation:

Cost of car = RM12,750

interest charged = 4% = 0.04

total interest paid = RM1,041.25

Now,

Using the Constant Ratio formula

r = \frac{24\times\textup{i}}{\textup{P(n+1)}}

here,

i is the interest paid

P is the principle

n is the number of monthly installments

r is the interest rate

on substituting the respective values, we get

0.04 = \frac{24\times\textup{1041.25}}{\textup{12,750(n+1)}}

or

n + 1 = 49

or

n = 48 months

Suppose y varies jointly as x & z. If y = -180 when z = 15and x = -3,then find y when x = 7 and z = -5. 1 point
sweet [91]

Answer:

y = - 140

Step-by-step explanation:

The statement

y varies jointly as x & z is written as

<h3>y = kxz </h3>

to find y when x = 7 and z = -5 we must first find the relationship between the variables

when y = - 180

z = 15

x = - 3

- 180 = k(15)(-3)

-180 = - 45k

Divide both sides by - 45

k = 4

The formula for the variation is

<h2>y = 4xz</h2>

when

x = 7

z = -5

y = 4(7)(-5)

y = 4(-35)

<h3>y = - 140</h3>

Hope this helps you
