The degree of the equation is 12 which means it's even. The leading coefficient is 7 which means it's positive. According to the these, the end behavior of the graph is:

f(x)→+∞, as x→−∞
As x approaches negative infinity, the value of f(x) approached positive infinity

f(x)→+∞, as x→+∞
As x approaches positive infinity, the value of f(x) approached positive infinity

The population of grand island, nebraska, grew by 600,000 people between 1995 and 2005, one fifth more than the town council ori

IgorLugansk [536]

Answer:

500000 people

Step-by-step explanation:

The population grew by 600,000 which is 120% the earlier prediction by the town council.

Using direct proportion

600,000 -------- 120%

X --------- 100%

X = (600000 × 100) ÷ 120 = 500000

Therefore the earlier prediction by the town council is 500000 people

Find the x-intercepts and y-intercept of the following function (x−5)(x−3)(4x+8)

Sergio [31]

X-intercepts:
(x-5)(x-3)(4x+8)=0

x-5=0 x-3=0 4x+8=0
x=5 x=3 x=-8/4
x=-2

Y-intercept:
sub x=0
(0-5)(0-3)(4(0)+8)=y

(-5)(-3)(8)=y

y = 120

Dave is considering two loans. Loan U has a nominal interest rate of 9. 97%, and Loan V has a nominal interest rate of 10. 16%.

Vsevolod [243]

Loan U will have a lower effective interest rate, and 0.0713 lower percentage points lower than Loan V and it can be determined by using the rate of interest formula.

Given that,

Dave is considering two loans.

Loan U has a nominal interest rate of 9.97%, and Loan V has a nominal interest rate of 10.16%.

If Loan U is compounded daily and Loan V is compounded quarterly.

We have to determine,

Which loan will have the lower effective interest rate, and how much lower will it be?

According to the question,

<h2>Effective Interest Rate;</h2>

The effective interest rate is determined by the formula;

$= \left(1+\dfrac{r}{t} \right )^t$
