Evaluate e^4 to one decimal place.

Answers

Answer 1

Answer:

Answer:

The $e^(4)$ to one decimal is 54.6

Step-by-step explanation:

we need to calculate $e^(4)$ to one decimal.

Since, $e^(x)=1+(1)/(x!)+(x^(2))/(2!)+(x^(3))/(3!)+......$ ....(1)

To calculate $e^(4)$ , put x=4 in equation (1)

$e^(4)=1+(1)/(4!)+(4^(2))/(2!)+(4^(3))/(3!)+......$

$e^(4)=1+(1)/(24)+(16)/(2)+(64)/(6)+......$

simplify the above expression

$e^(4)=1+(1)/(24)+(16)/(2)+(64)/(6)+(256)/(24)+(1024)/(120)......$

calculate with the scientific calulator

< 0.1 =54.6

Hence, $e^(4)$ to one decimal is 54.6

Answer 2

Answer: The answer is going to be the general form for e^x = 1 + x/(1!) + + x^2/(2!) + x^3/(3!) +.....,. till infinity so : e^4 = 1 + 4/1 + 16/ 2 + 64/6 + 256/24 + 1024/ 120 + 4096/720 + 16384/5040 +...till the fraction is<0.1 = 54.6

I hope this helps!

What two whole numbers is the quotient between? 38\div438÷438, divided by, 4 Choose 1 answer: Choose 1 answer: (Choice A) A 333 and 444 (Choice B) B 555 and 666 (Choice C) C 888 and 999 (Choice D) D 999 and 101010

Answers

Answer:

(D) 9 and 10

Step-by-step explanation:

Given the quotient: 38÷4

$(38)/(4)=9 (2)/(4)=9 (1)/(2)$

Since $9 (1)/(2)$ is greater than 9 but less than 10,

$9<9 (1)/(2)<10$

It therefore lies in between 9 and 10.

If 4x - 3 = 5, then x=

Answers

Answer:

x=2

Step-by-step explanation:

4x-3=5

4x-3 plus 3 and 5 plus 3

4x=8

Divide both sides by 4

x=2

Answer:

X = 2

Step-by-step explanation:

This is how I got the answer:

Move constant to the right-hand + change signs

4x = 5 + 3

add

4x =5 + 3

4x = 8

Divide by both sides to get the answer of;

X = 2

Are the angles with the given measures complementary, supplementary, or neither? m∠J = 63° and m∠K = 27°

Answers

They're complementary.
Complementary angles are a pair of two angles that add up to a sum of 90 degrees
Supplementary angles add up to 180 degrees
63 + 27 = 90

well if the total is 90 so its complementary...
