If x³ + 2x and x³ − 7x² + 4x +2 + k have a common linear polynomial factor, then the value of k is what?

Georgia [21]

Answer:

k = -2

Step-by-step explanation:

<u>Factor x³ + 2x:</u>

x³ + 2x = x(x² + 2)

1. <u>The common factor is x, then</u>:

2 + k = 0 ⇒ k = -2 (all the rest are divisible by x)

2. Factor x² + 2 is not linear therefore we discard it.

Compound interest . A student get a grant of $10000 a year assuming her grant is increased by 7% each year what will her grant b

Klio2033 [76]

Answer:

Her grant in four years time will be of $13108.

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

$A(t) = A(0)(1+r)^t$

In which A(0) is the initial value and r is the growth rate, as a decimal.

A student get a grant of $10000 a year assuming her grant is increased by 7% each year

This means that $A(0) = 10000, r = 0.07$

$A(t) = A(0)(1+r)^t$

$A(t) = 10000(1+0.07)^t$

$A(t) = 10000(1.07)^t$

What will her grant be in four years time?

This is A(4). So

$A(t) = 10000(1.07)^t$

$A(4) = 10000(1.07)^4 = 13108$

Her grant in four years time will be of $13108.
