Answer:

-2sqrt(3)) + 2(sqrt(15)

Step-by-step explanation:

sqrt(12) * (-1 + sqrt(5)) = -sqrt(12) + sqrt(12 * 5) = -sqrt(4 * 3) + sqrt(4 * 15) =

= -2sqrt(3)) + 2(sqrt(15)

use natural logarithms to solve the equation. round to the nearest thousandth. show work!! 5e^(2x+11) =30

rosijanka [135]

Answer:

x = -4.604

Step-by-step explanation:

Here, we want to get the value of x

We start by dividing through by 5

e^(2x + 11) = 30/5

e^(2x + 11) = 6

Writing this in natural logarithm form, we have;

ln 6 = 2x + 11

2x + 11 = 1.792

2x = 1.792-11

2x = -9.208

x = -9.208/2

x = -4.604

A car travels 32 miles for each gallon of gas.How many gallons of gas does it need to travel 192 miles

gladu [14]

Hi there! :)

Answer:

The car needs 6 gallons of gas to travel 192 miles.

Step-by-step explanation:

In order to answer your question, you'll need to use the cross product method:

32 miles → 1 gallon

192 miles → X gallons

(1 × 192) ÷ 32 = X gallons

192 ÷ 32 = X gallons

6 = X gallons

There you go! I really hope this helped, if there's anything just let me know! :)

Choose the number pair that has digits of 4 that differ in place by a factor of 1000. 4 A. 49,823 and 81,540 B. 83,419 and 46,85

Ne4ueva [31]

Answer:

The correct option is D) 47,063 and 54,722.

Step-by-step explanation:

Consider the provided information.

Here we need to find the number pair that has digits of 4 that differ in place by a factor of 1000.

Now consider the option A) 49,823 and 81,540

The place value of 4 in 49,823 and 81,540 is 40,000 and 40 respectively.

So the difference=40,000-40=39960 which is not a multiple of 1000.

Consider the option B) 83,419 and 46,859

The place value of 4 in 83,419 and 46,859 is 400 and 40,000 respectively.

So the difference=40,000-400=39600 which is not a multiple of 1000.

Consider the option C) 54,890 and 81,745

The place value of 4 in 54,890 and 81,745 is 4000 and 40 respectively.

So the difference=4000-40=3960 which is not a multiple of 1000.

Consider the option D) 47,063 and 54,722

The place value of 4 in 47,063 and 54,722 is 40,000 and 4000 respectively.

So the difference=40000-4000=36000 which is a multiple of 1000.

Hence, the correct option is D) 47,063 and 54,722.
