Let f(x) = 8x3 − 28x + 61 and g(x) = 2x + 5. Find f of x over g of x.

Answer:

$4x^2-10x+11+\frac{6}{2x+5}$

Step-by-step explanation:

The given functions are:

$f(x)=8x^3-28x+61$ and $g(x)=2x+5$

By algebraic properties of functions;

$\frac{f(x)}{g(x)}=\frac{8x^3-28x+61}{2x+5}$

We perform the long division of the two polynomials as shown in the attachment.

Therefore:

$\frac{8x^3-28x+61}{2x+5}=4x^2-10x+11+\frac{6}{2x+5}$

The last choice is correct

Evaluate in 5. A.) 0.62 B.) 0.70 C.) 1.61 D.) 1.95

Len [333]

Answer:

option C) 1.61

Step-by-step explanation:

The question is to evaluate the natural logarithm of 5. Natural logarithms are logarithms with base e.

e is the irrational number equal to 2.71828182845904523536028747 ... (being irrational the decimals do not end and do not have a repetition period).

Logarithms are evaluated using tables or scientific calculators.

ln (5) = 1.6094379... it is also an irrational number, so it has infinite decimals with no repetition period.

So, rounding to two decimal numbers, ln (5) = 1.61, which is the option C).
