Answer:

Option D: - 6; $\textbf{-5}\frac{\textbf{5}}{\textbf{2}}$ ; $\textbf{-4}\frac{\textbf{1}}{\textbf{5}}$ .

Step-by-step explanation:

The sequence is defined by:

$A(n) = -6 + (n - 1)\bigg( \frac{1}{5} \bigg )$

To find the first term of the sequence simply substitute n = 1.

First term of the sequence:

$A(1) = -6 + (1 - 1)\bigg( \frac{1}{5} \bigg )$

$= - 6$

Fourth term of the sequence:

$A(2) = -6 + (4 - 1) \bigg ( \frac{1}{5} \bigg)$

$= - 6 + 3\bigg( \frac{1}{5} \bigg)$

$= \frac{- 30 + 3}{5}$

$= \frac{-27}{5}$

$= \frac{-25 - 2}{5}$

$= - 5 - \frac{2}{5}$

$= -5\frac{2}{5}$ is the required answer.

Tenth term of the sequence:

$A(10) = - 6 + (10 - 1) \bigg( \frac{1}{5} \bigg)$

$= - 6 + 9\bigg( \frac{1}{5} \bigg)$

$= \frac{-30 + 9}{5}$

$= \frac{-21}{5}$

$= \frac{-20 - 1}{5}$

$= - 4 - \frac{1}{5}$

$= -4\frac{1}{5}$ is the required answer.

Vlada [557]

The problem can be represented by the the exponential growth formula which is :
$P(t) = A * r^{t}$
Where: t ⇒ time , A ⇒ initial amount , r ⇒ rate of increase
P(t) ⇒ predicted amount at the end of t.

For the given problem:
initial amount = A = $278,640
predicted increase in value per year = 4% =0.04

∴ r = 1 + 0.04 = 1.04

for t = 18 years

∴ $P(t) = A * r^{t} =278,640 * 1.04^{18}=\framebox{564,473.5}$ 
Rounding to the nearest dollar ⇒ ∴ P(t) = 564,474


So, the predicted value of David's home in 18 years = $564,474

So, The correct option is $564,474

The tires of a go-cart are 1 m in circumference. The tires revolve 15 times per second. What is the distance the go-cart travels

Likurg_2 [28]

Answer:

600 m

Step-by-step explanation:

The circumference of a tire is the distance around it. The distance around these tires is 1 m.

Since the tires revolve 15 times per second, this means every second the tires travel 15 m.

This means that in 40 seconds, the tires travel

15(40) = 600 m.
