Serhud [2]

Answer:

$P^{-1} (x)=\sqrt{\frac{x-1}{2} }$

Step-by-step explanation:

1. $P(x)=2x^{2} +1$

2. $y=2x^{2} +1$

3. $x=2y^{2} +1$

4. $2y^{2} =x-1$

5. $y^{2} =\frac{x-1}{2}$

6. $y=\sqrt{\frac{x-1}{2} }$

7. $P^{-1} (x)=\sqrt{\frac{x-1}{2} }$

gladu [14]

Answer:

Question 7: Distance = 237.6 km

Question 8: Distance = 399.3 km

Step-by-step explanation:

Question 7:

Given:

Minimum speed (s) = 72 km/hr

Time taken (t) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Minimum speed × Time

Distance = $s\times t$

Distance = $72\times 3.3 = 237.6\ km$

Therefore, distance traveled at this speed is 237.6 km.

Question 8:

Maximum speed (S) = 121 km/hr

Time taken (T) = 3.3 hours.

We know that, distance traveled is equal to the product of speed and time.

Therefore using distance formula, we get:

Distance = Maximum speed × Time

Distance = $S\times T$

Distance = $121\times 3.3 = 399.3\ km$

Therefore, distance traveled at this speed is 399.3 km.
