Increase.

1/4 can be translated to 25%

1/2 can be translated to 50%

25% to 50% is an increase.

Increase because 1/4 can be known as 25 percent and 1/2 known as 50 percent

I assume you mean -x^3 + 4x + 3
so what you need is 4x + 3 > x^3
the only whole number it could be is 2 because 2x2x2 +3 > 2x2x2

A new 2006 Honda head was values at $25000. It depresides at a rate of 13% a year.

CaHeK987 [17]

Answer:

1. It's value in 2009 was $16,462.575

2. It's value in 2020 will be $3,558.

Step-by-step explanation:

The equation for the value of car after t years has the following format.

$V(t) = V(0)(1-r)^{t}$

In which V(t) is the value after t years, V(0) is the initial value and r is the ratio of depreciation.

In this problem, we have that:

$V(0) = 25000, r = 0.13$

$V(t) = V(0)(1-r)^{t}$

$V(t) = 25000(1-0.13)^{t}$

$V(t) = 25000(0.87)^{t}$

1. What was its value in 2009

2009 is 3 years after 2006, so this is V(3)

$V(t) = 25000(0.87)^{t}$

$V(3) = 25000(0.87)^{3}$

$V(3) = 16462.575$

It's value in 2009 was $16,462.575

2.What will be its value in 2020?

2020 is 14 years after 2006, so this is V14)

$V(t) = 25000(0.87)^{t}$

$V(14) = 25000(0.87)^{14}$

$V(14) = 3558$

It's value in 2020 will be $3,558.

Ayla saves up $204 and spends $35.50 on books. She wants to purchase more books, which are on sale for $8.25 each. How many more

pogonyaev

Answer:

20 more books

Step-by-step explanation:

£204 - £35.50 = £168.50

168.50/8.25 = 20.42

We obviously can't buy 0.42 of a book, so you round down and get 20 books
