Arrange the given polynomial in descending order. 9x? + 9x +3+2x

1 answer:

7 0

20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!

Oxana [17]

Answer:

time is 6.76 years

Step-by-step explanation:

given data

amount = $150

payment = $100

rate r = 6% = 0.06

to find out

time period t

solution

we know it is compounding continuous

so we will apply here formula that is

amount = payment × $e^{rt}$ ..........1

put here all value we get

amount = payment × $e^{rt}$

150 = 100 × $e^{0.06t}$

take ln both side

ln 1.5 = $e^{0.06t}$

0.40546 = 0.06t

t = 0.40546 / 0.06

t = 6.76

so time is 6.76 years

Ratling [72]

Answer:

$(10.3(2.5)+3.1(2))\div 110$

Step-by-step explanation:

$A_1$ = Area of 1st rectangle = $(10.3\times 2.5)\ \text{ft}^2$

$A_2$ = Area of 2nd rectangle = $(3.1\times 2)\ \text{ft}^2$

$1\ \text{pound of grout}=110\ \text{ft}^2$

$\Rightarrow 1\ \text{ft}^2=\dfrac{1}{110}\ \text{pound of grout}$

The number of pounds required for the counter top is

$\text{Total area}\times \text{The amount of grout used in 1 ft}^2$

$=A_1+A_2\times \dfrac{1}{110}=(10.3(2.5)+3.1(2))\times \dfrac{1}{110}\\ =(10.3(2.5)+3.1(2))\div 110$

The required expression is $(10.3(2.5)+3.1(2))\div 110$ .
