Answer:
The difference of squares is (a - b)(a + b) = a² - b². Since a = x and b = 2, the answer is x² - 4.
<u>Answer:</u> 100
<u>Reasoning:</u> The median is the "middle value" and to find it put the numbers in order from least to greatest.
22, 43, 100, 102, 108.
now take a number from both sides
43, 100, 102
Once again.
100
So 100 is the median.
Answer:
r = 5sec(θ)
Step-by-step explanation:
The usual conversion is ...
y = r·sin(θ)
x = r·cos(θ)
__
The second of these can be used here.
r·cos(θ) -5 = 0
r·cos(θ) = 5
r = 5/cos(θ) = 5sec(θ)
A suitable polar equation is ...
r = 5sec(θ)
<h3><u>Answer :- </u></h3>
168 km ...
<h3><u>Explanation :- </u></h3>
It is given that the car travels 14km in 25 minutes..
Now , assume that the distance the car travel in 5 hours be x..
- Since 1 hour = 60 minutes..
- 5 hours = 300 minutes ..
• Thus , The two given statements are :-
- 14km -----------------> 25 minutes..
- And, x km -------------> 300 minutes..
<h3><u>We know that , </u></h3>
- The distance travelled by car and the time taken by the car is directly proportional to each other....
<h3>So , </h3>


• Hence , Car can travel 168km in 5 hours ..
Hope this helps you :)
