Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving

Zarrin [17]

Answer: The function that models the distance they drive is

f(x) = 50x + 20 where x is the time in hours

reasonable domain: 0 ≤ x ≤ 3

Step-by-step explanation:

examples:

95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.

120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.

There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t

20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.

120 = 5(2.4) The whole trip took 2.4 hours.

Please help me I’m struggling :’(

Vesna [10]

Answer:

B. $x = \sqrt{40}$

Step-by-step explanation:

Using Pythagorean theorem, find the value of x.

Pythagorean theorem is given as $c^2 = a^2 + b^2$

Where,

c is the longest side of a right angled ∆ = the hypotenuse = x

a and b are legs of the right angled ∆ = 2 and 6

Plug in the values into the equation and solve for x

$x^2 = 2^2 + 6^2$

$x^2 = 4 + 36$

$x^2 = 40$

$x = \sqrt{40}$

Rewrite the logarithm as a ratio of common logarithms and natural logarithms. log4 45

tiny-mole [99]

Answer:

Common logarithm

$log_451= \frac{log_1_045}{log_1_08}$

Natural logarithms

$log_445= \frac{log_e45}{log_e4}$

$log_445= \frac{In45}{In4}$

Step-by-step explanation:

From the question we are told that

$Log_445$

Generally converting log from base x to base 10 si mathematically represented as

$log_xa=log_1_0a *log_x10$

$log_xa= \frac{log_1_0a}{log_1_0x}$

Therefore

Common logarithm

$log_451= \frac{log_1_045}{log_1_08}$

Generally Natural logarithms $log_ex\ or\ inx$ is mathematically represented as

$log_xa= \frac{log_ea}{log_ex}$

Therefore

Natural logarithms

$log_445= \frac{log_e45}{log_e4}$

$log_445= \frac{In45}{In4}$
