Answer:

$a_{n}$ = 8 $(-3)^{n-1}$

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = 8 and r = - 24 ÷ 8 = - 3, thus

$a_{n}$ = 8 $(-3)^{n-1}$

If p(x)=2x^3+cx^2+16x+84 and x+2 is a factor of p(x),find the value of c.

Nuetrik [128]

Answer:

c = -9

Step-by-step explanation:

Knowing that -2 is a root, you can do the synthetic division with an unknown value for c. Then solve for the value of c that makes the remainder be zero. See the attachment for the work.

The second attachment shows that (x+2) is a factor of the resulting cubic.

if Angela's house is assessed valuation of $61,200 and the tax rate per 100 is $3.78 what will she pay in annual real estate tax

poizon [28]

Answer:

$\boxed{\text{\$2313.40}}$

Step-by-step explanation:

The tax rate is $3.78/$100 assessed

$\text{Tax} = \text{\$61 200 assessed} \times \dfrac{\text{\$3.78}}{\text{\$100 assessed}}$

Cancel the $100 assessed.

612 × $3.78 = $2313.40

Angela's real estate tax will be $\boxed{ \textbf{\$2313.40}}$

Susan will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $70 and costs an ad

swat32

Answer:

350 miles

Step-by-step explanation:

Let x represent the miles driven

The cost with the first plan will be represented by 0.40x + 70

The second plan will be represented by 0.60x

Set these 2 expressions equal to each other and solve for x:

0.40x + 70 = 0.60x

70 = 0.20x

350 = x

So, Susan will have to drive 350 miles for the cost to be the same
