Juan is three times as old as Gabe and Gabe is six years older than Catherine. If the sum of their ages is 149, how old is each
cestrela7 [59]

Answer:

Juan = 93 years.

Gabe = 31 years.

Catherine = 25 years.

Step-by-step explanation:

Let the age of Juan = J

Let the age of Gabe = G

Let the age of Catherine = C

<em>Translating the word problem into an algebraic equation, we have;</em>

J = 3G ..........equation 1

G = C + 6 ........equation 2

J + G + C = 149 ........equation 3

<em>We would solve the linear equations by using the substitution method; </em>

<em>Substituting equation 2 into equation 1;</em>

J = 3(C + 6)

J = 3C + 18 ........equation 4

<em>Substituting equation 2 and equation 4 into equation 3;</em>

(3C + 18) + (C + 6) + C = 149

<em>Simplifying the equation, we have;</em>

5C + 24 = 149

5C = 149 - 24

5C = 125

C = \frac {125}{5}

C = 25 years.

To find G; from equation 2

G = C + 6

Substituting the value of "C" into equation 2, we have;

G = 25 + 6

G = 31 years.

To find J; from equation 1

J = 3G

Substituting the value of "G" into equation 1, we have;

J = 3 * 31

J = 93 years.

<em>Therefore, Juan is 93 years old, Gabe is 31 years old and Catherine is 25 years old. </em>

Is there a relationship between the degree of a polynomial and how "steep" it is on the left and right edges? If so, what is it
victus00 [196]

Answer:

The larger the degree, the steeper the graph's branches towards the right and left edges.

Step-by-step explanation:

Yes, there is a relationship between the degree of a polynomial and how steep its branches are at their end behavior (for large positive values of x, and to the other end: towards very negative values of x).

This is called the "end behavior" of the polynomial function, and is dominated by the leading term of the polynomial, since at very large positive or very negative values of the variable "x" it is the term with the largest degree in the polynomial (the leading term) the one that dominates in magnitude over the others.

Therefore, larger degrees (value of the exponent of x) correspond to steeper branches associated with the geometrical behavior of "power functions" (functions of the form:

f(x)=a_n\,x^n

which have characteristic end behavior according to even or odd values of the positive integer "n").

Recalling the behavior of such power functions, the larger the power (the degree), the steeper the graph.

2. The functions ???? and ???? represent the population of two different kinds of bacteria, where x is the time (in hours) and ?
klio [65]

Answer:

(a) Bacterial 1 had a faster rate of growth.

(b) The population of f(x) always exceed the population of g(x). In other words, population of g(x) cannot exceed the population of f(x).

Step-by-step explanation:

Consider the given functions are

f(x)=2x^2+7

g(x)=2x

where, x is the time (in hours) and f(x) and g(x) are the number of bacteria (in thousands).

(a)

The rate of change of a function f(x) on [a,b] is

m=\frac{f(b)-f(a)}{b-a}

Rate of change between third and sixth hour of first function is

m_1=\frac{f(6)-f(3)}{6-3}

m_1=\frac{(2(6)^2+7)-(2(3)^2+7)}{6-3}

m_1=\frac{79-25}{3}

m_1=\frac{54}{3}

m_1=18

Rate of change between third and sixth hour of second function is

m_2=\frac{g(6)-g(3)}{6-3}

m_2=\frac{2(6)-2(3)}{6-3}

m_2=\frac{12-6}{3}

m_2=\frac{6}{3}

m_2=2

Since m_1>m_2, therefore bacterial 1 had a faster rate of growth.

(b)

The initial population of f(x) is 7 and it increases exponentially.

The initial population of g(x) is 0 and it increases linearly.

It means population of f(x) always exceed the population of g(x).

In other words, population of g(x) cannot exceed the population of f(x).
