Answer: x=31.25

Step-by-step explanation: a'2 + b'2 = c'2. 5'2+ b'2=7.5'2. 25+b'2=56.25. 56.25-25=b'2.

Some four-digit numbers, such as 3003 and 6226, read the same forward and backward. If a boy selects a number from all four-

Norma-Jean [14]

Answer:

The probability of selecting such number = $\frac{90}{9000} = \frac{1}{100}$

Explanation:

4-digit numbers start from 1000 and ends at 9999

So, there are 9000 4-digit numbers present

There are 90 palindrome numbers (which reads the same forward and backward) present between 1000-9999. They are 1001; 1111; 1221; 1331; ... 1001; 1111; 1221; 1331; ... to 9669; 9779; 9889; 9999; 9669; 9779; 9889; 9999

Therefore, the probability of selecting such number = $\frac{90}{9000} = \frac{1}{100}$

How are discontinuities and zeros created in rational expressions, and in what ways can they be accounted for graphically?

pshichka [43]

Discontinuities can be recognized by observing at asymptotes. An asymptote is a line where the space between the curve and the line go to zero as single or both of the x or y coordinates inclines to infinity. Graphically, they're holes in the graph. Zeroes are points wherever the graph hits the x axis.
