son4ous [18]
Alvin's age + Elga's age = 84
2R + R                             = 84 
3 R                                   = 84
3/ 3 R = 84/ 3 
R = 28 
Elga's age is 28

2. What is the effective annual rate of an investment that pays 6% for 5 years, compounded semiannually?
Ede4ka [16]

Answer:

effective annual rate is 6.16 %

Step-by-step explanation:

given data

rate = 6 % = 0.06

time 5 year = 10 semi annually

to find out

effective annual rate

solution

we know formula for annual effective rate of interest is

rate of  interest = (1+ r/n)^{n} -1

put here all value

rate of interest = (1+ 0.06/10)^{10} -1

rate of  interest = (1+ 0.06/10)^{10} -1

rate of interest = 0.061646

so effective annual rate is 6.16 %

State the degree and end behavior of f(x) = 2x3 – 3x – x2 + 1. Explain or show<br> your reasoning
Olin [163]

Answer:

Answer:

As x→∞ , f(x)→-∞

As

x→-∞ , f(x)→∞

Step-by-step explanation:

End behavior is determined by the degree of the polynomial and the leading coefficient (LC).

The degree of this polynomial is the greatest exponent, or

3

.

The leading coefficient is the coefficient of the term with the greatest exponent, or

2

.

For polynomials of even degree, the "ends" of the polynomial graph point in the same direction as follows.

Even degree and positive LC:

As x→∞ , f(x)→∞ As x→∞, f(x)→∞

Even degree and negative LC:

As x→−∞ , f(x)→−∞

As

x→∞ , f(x)→−∞
