Mathematics
1 answer:
professor190 [17]2 years ago
3 0

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

  arc = 2πr × \frac{60}{360}

        = 2π × 18 × \frac{1}{6}

        = 36π × \frac{1}{6}

        = 6π ≈ 18.8 cm ( to 1 dec. place )

4. 10. 4 Test (CST):
kompoz [17]

Based on the value of the annuity, the amount it earns, and the compounding period, the money paid to Nathan each month will be B. $5,840.62.

<h3>How much will Nathan be paid monthly?</h3>

The amount Nathan will be paid is an annuity because it is constant.

First find the monthly interest and the compounding period in months:
= 4.8/12 months

= 0.4%

Number of compounding periods:

= 20 x 12

= 240 months

The monthly payment is:

Present value of annuity = Annuity x ( 1 - (1 + rate) ^ -number of periods) / rate

900,000 = A x ( 1 - (1 + 0.4%)⁻²⁴⁰) / 0.375%

900,000 = A  x 154.0932

A = 900,000 / 154.0932

= $5,840.62.

A.
-1: 
2(2)^{-1}  \\ 2( \frac{1}{2}) \\  \frac{2}{2}  \\ 1
(-1,1)

0:
2(2)^{0} \\ 2(1) \\ 2
(0, 2)

1:
2(2)^{1}  \\ 2(2) \\ 4
(1, 4)

2:
2(2)^{2} \\ 2(4) \\ 8
(2, 8)

3:
2(2) ^{3}  \\ 2(8) \\ 16
(3,16)

b.
To graph the equation, simply go through the points (-2, 0.5), (-1, 1), (0,2), (1,4), (2,8), and (3,16). Make sure you never go below 0 on the x-axis, because there's an asymptote there.

Hope this helps!
