Answer:
<h3>A. </h3>- log
= log 3
- x³ log x = log 3
- 3x³ log x = 3 log 3
- x³ log x³ = log 3³
= 3³
- x³ = 3
- x =
- 4ˣ + 6ˣ = 9ˣ
- 2²ˣ + 2ˣ3ˣ = 3²ˣ
<u>Divide both sides by 2²ˣ</u>
- 1 + (3/2)ˣ = (3/2)²ˣ
<u>Substitute (3/2)ˣ = t</u>
- t² - t - 1 = 0
<u>Solve for t:</u>
- t = (1 ± √5)/2
<u>Positive root is considered as (3/2)ˣ can't be negative.</u>
- (3/2)ˣ = (1 + √5)/2
- x = log [(1 + √5)/2] / log (3/2)
- x = 1.18681439028
The distance of a vehicle travel is 150 km, at a moving rate of 60 km/h for 150 minutes.
Step-by-step explanation:
The given is,
Moving rate, r = 60 km/h
Time, t = 150 minutes
Step:1
We need to find the distance traveled by the vehicle,
From given the formula is
D = rt
Where,
D = Distance in Km
r = Moving rate in Km/h
t = Time in hours
Step:2
We need to convert the time minutes to hours
t = hours
t = 2.5 hours
Step:3
Distance traveled by the vehicle is,
D = 60 × 2.5
= 150
D = 150 Km
Result:
The distance traveled by the vehicle is 150 Km at a moving rate of 60 km/h for 150 minutes.
