Answer:
980 Km
Step-by-step explanation:
Calculate the speed of the car from the table
speed =
Using any value from the table , say distance = 140 , time = 2 hours , then
speed = = 70 Km per hour
distance = speed × time
= 70 × 14
= 980 Km

Step-by-step explanation:
From the question we are told that
The concentration of HF is [HF] = 0.6 M
The concentration of NaF is
The Ka of HF is
Generally HF(Hydrogen fluoride ) is ionized as follows
Generally NaF(Sodium fluoride ) is ionized as follows
Generally the from Henderson-Hasselbalch equation the pH of the buffer is mathematically represented as

Domain are all the possible x values of a function. When you look at a cosine graph you can see that it goes on into infinity in the x or horizontal direction. This means that all x values are included in cosine. Because of this the domain is:
all real numbers
or
(-∞,∞)
^^^ It can be written both ways

Answer:
Step-by-step explanation:
1. Convert the decimal into a fraction by doing this. Take 1.8 and write it above a fraction line without the decimal sign.
2. Count the decimal places and below the fraction line write the multiple of 10 with that many zeros so that would
3. Simplify the fraction so that would be .
4. Now in order to divide a fraction, multiply by the reciprocal of that fraction so that would be .
5. Now reduce the number with the gcf (greatest common factor) which would be 5. So now we have 9*
6. Reduce the numbers again using the gcf which now would be 9. Now you have the answer which should
