The set of two-digit primes is {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97}

Of that list, the following primes are mirror images of each other
13 and 31
17 and 71
37 and 73
79 and 97
Note: we ignore 11 since 11 flips to 11 which is not distinct from its original

If you're looking for the largest prime of this form, then its 97
If you're looking for the largest gap, then subtract each pair
31-13 = 18
71-17 = 54
73-37 = 36
97-79 = 18
We see that 71 and 17 have the largest gap

The digits cannot be 2, 4, 6, 5, 8, because those numbers in the one's place do not make a prime number.
of the numbers 1, 3, 7, 9, and largest is 97, and 79 is also a prime number, so the answer is 97

Look at the graphs and their equations below. Then fill in the information about the leading coefficients A overline B Cand D
Tresset [83]

Explanation

,the leading term is the term containing the highest power of x. The coefficient of the leading term is called the leading coefficient.

\begin{gathered} ax^2+bx+c=0 \\ a\text{ is the leading coefficient} \end{gathered}

Step 1

a)

an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

therefore

\begin{gathered} graph\text{ A}\Rightarrow open\text{ downward}\Rightarrow negative \\ graphB\operatorname{\Rightarrow}open\text{upwards}\operatorname{\Rightarrow}pos\imaginaryI t\imaginaryI ve \\ graphC\operatorname{\Rightarrow}\text{ open upwards}\Rightarrow positive \\ graphD\operatorname{\Rightarrow}open\text{downward}\operatorname{\Rightarrow}negat\imaginaryI ve \end{gathered}

Step 2

b)the leading coefficient "a" indicates how "fat" or how "skinny" the parabola will be.

for

\begin{gathered} \lvert{leading\text{ coefficent}}\rvert>1,\text{ the parabola will be ''skinny''} \\ \lvert{\text{leadin coefficien}}\rvert

hence, more the skinny the graph is, the more closet to zero

therefore,the coefficient closest to 0 is C

Step 3

c)simiary, the graph with the leading coefficient with the grates value will be

graph B

because the coefficient is greater than zero and this graph is the more "fat"

I hope this helps you
