What is the answer to 2log3(x)=4?

Mathematics
1 answer:
Marysya12 [62]4 years ago
8 0

Answer:

x ≈ 4.19180

Step-by-step explanation:

2 log 3(x) = 4

2 log(3)(x) = 4

Divide both sides by 2log (3) to isolate x by itself

\frac{2log(3)(x)}{2log(3)} = \frac{4}{2log(3)}

x = \frac{4}{2log(3)}

or x ≈ 4.19180

using a calculator you can write the answer as a rounded number

Solve for x. Show steps.<br><br>1. 3x = 2x + 2<br><br>2. 3x + 5 = 4x + 1<br><br>3. 6x + 3 = 3x + 12​
nignag [31]

Step-by-step explanation:

  1. 3x = 2x + 2

3x - 2x = 2

x = 2

2. 3x + 5 = 4x + 1

4x - 3x = 5 - 1

x = 4

3. 6x + 3 = 3x + 12

6x - 3x = 12 - 3

3x = 9

x = 3

A car travels a distance on a road of 12.42 miles at a slope of 6.4%. The car has a maximum speed of 203 mph. Assume the car wil
Neko [114]

Answer:

4 mins 31 seconds

Step-by-step explanation:

Maximum speed is 203 mph equivalent to

203*\frac {5280}{3600}=297.73 ft/s

Time taken to attain maximum speed, t=\frac {v}{a} where v is velocity and a is acceleration hence

t=\frac {297.73}{2.93}=101.6155 s

The distance traveled when at top speed

d=\frac {v^{2}}{2a}=\frac {(297.73)^{2}}{2*2.93}=15127.16 \approx 15127.2 ft

Total distance is provided as 12.42 miles converted to ft is 12.42*5280=65577.6 ft

Total distance-distance moved to attain maximum speed will be

65577.6 ft-15127.2 ft=50450.44 ft

Time taken during maximum speed

t=\frac {50450.44}{297.73}=169.45 s

Total time=101.6155 s+169.45 s=271.06 s

271.06/60=4 mins 31 seconds

8. Aaron and Zelly want to rent a tandem bike so that
ololo11 [35]

Answer:

80 = 18.50h + 6

Step-by-step explanation:

Given

Amount = \$80

Rent = \$18.50 per hour

Helmet = \$3.0

Individuals =2

Required

Derive an expression for the scenario

A tandem bike allows 2 individuals to ride on it at a time.

So, they will only pay for one rental fee because both can ride on it at the same time.

However, they need to get separate helmets.

For Helmets, they will spend:

\$3 * 2 =\$ 6

For Rental, they will spend

\$18.50 * h = \$18.50h for h hours.

Total = Rentals + Helmets

Total = 18.50h + 6

Recall that they have just $80 to spend

So, substitute 80 for total

80 = 18.50h + 6

Hence, option C answers the question.
