A triathlon athlete swims at an average rate 2.4 miles per hour, and bikes at an average rate of 16.1 miles per hour. At the end of one training session, she has swum and biked
more than 20 miles in total.

The inequality 2.4s + 16.16 > 20 and this graph represent the relationship between
the hours of swimming, s, the hours of biking, h, and the total distance the athlete could
have traveled in miles.

Mai said, "I'm not sure the graph is right. For example, the point (10,3) is in the shaded
region, but it's not realistic for an athlete to swim for 10 hours and bike for 3 hours in a
training session! I think triathlon athletes generally train for no more than 2 hours a day."

Question 4

Write an inequałty for the time constraints (using the hours of swimming s and the
hours of bikingh as your variables) to represent Mai's last statement, "...I think triathlon
athletes generally train for no more than 2 hours a day."

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
