Answer:

Step-by-step explanation:

Given f(x) = 4 - 7x^5

Note the ^5 on x and the -7 in front of x^5

f(x) is a polynominal function. The degree is 5 and the leading coefficient is -7.

Given x -> ∞, f(x) -> ∞ and x -> -∞, f(x) -> -∞

Because (-x)^(2n) = x^(2n), the polynominal's degree cannot be an even number.

If the lead coefficient ax^n is negative, x -> ∞, f(x) -> -∞. So the lead coefficient cannot be negative.

Among the choice, the only correct answer is f(x) = 7x^9 - 3x^2 - 6

From the graph, the polynominal reaches its max at x=1 and mini at x=-2 and x=3.

Of the three extrema, only the one at x=-2 is the global mini while at x=3 is a local mini and at x=1 is a local max.

So the last two statements are correct.

Answer:

Step-by-step explanation:

ans is c) f(x) is a polynominal function. The degree is 5 and the leading coefficient is -7.

x -> ∞, f(x) -> ∞; x -> -∞, f(x) -> -∞

the only ans that follows the above is a) f(x)=7x^9-3x^2-6

correct statments are:  c)  (1, 6.08) and (3, 0.75) are local extrema for the function and  d)  (-2, -9.67) is the global minimum for the function.

Suppose a family has three children of different ages. We assume that all combinations of boys and girls are equally likely. (a)
Ivan

Answer:

a) There are 8 possible combinations and each probability is 1/8.

b) The probability that it is a boy given that there are two girls is 3/8

Step-by-step explanation:

a) The sample space is given by:

BBB (3 boys)

BBG (Boy, boy, girl)

BGB (Boy, girl, boy)

BGG (Boy, girl, girl)

GBB (girl, boy, boy)

GBG (girl, boy, girl)

GGB (girl, girl, boy)

GGG (3 girls)

The probability of each combination is the same:

P(BBB)=P(B∩B∩B)=\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{1}{8}

2) There are three possible combinations in which there are 2 girls and 1 boy:

BGG, GBG, GGB

So the probability is given by:

P(BGG ∪ GBG ∪ GGB)=\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{3}{8}

When producing hydrogen iodide, the energy of the reactants is 581 kJ/mol, and the energy of the products is 590 kJ/mol. The equ
dimaraw [331]

The energy of the reaction is 9 kJ/mol and the reaction is endothermic.

<h3>What is the total energy of the reaction?</h3>

We know that in a reaction, there could be loss or gain of energy. If there is a loss of energy in a reaction, it means that the reaction is exothermic and heat is given out. If heat is gained in the reaction, it means that the reaction is endothermic and heat is absorbed.

Given that;

Energy of the products =  590 kJ/mol

Energy of the reactants = 581 kJ/mol

Using;

Energy of products - Energy of reactants

= 590 kJ/mol - 581 kJ/mol

= 9 kJ/mol
