Which is the best approximation to a solution of the equation e^x = 2x + 3?

TiliK225 [7]

The correct question is
Which is the best approximation to a solution of the equation
e^(2x) = 2e^{x) + 3?

we have that

e^(2x) = 2e^{x) + 3-----------> e^(2x)- 2e^{x) - 3=0
the term
e^(2x)- 2e^{x)----------> (e^x)²-2e^(x)*(1)+1²-1²------> (e^x-1)²-1

then
e^(2x)- 2e^{x) - 3=0--------> (e^x-1)²-1-3=0------> (e^x-1)²=4
(e^x-1)=2--------> e^x=3
x*ln(e)=ln(3)---------> x=ln(3)
ln(3)=1.10
hence
x=1.10

the answer is x=1.10

an image of a right triangle is shown with an angle labeled y If sin y° = 7 divided by q and tan y� = 7 divided by r, what is th

trapecia [35]

Answer:

cos y = r/q

Step-by-step explanation:

Sine is opposite divided by hypotenuse. Here, since sin y = 7/q, we can say that the opposite side length is 7 and the hypotenuse side length is q.

Tangent is opposite divided by adjacent. Here, since tan y = 7/r, we can say that the opposite side is 7 (just like above with sine) and the adjacent side is r.

Now, we have a triangle with its two legs labelled 7 and r and its hypotenuse labelled q.

Cosine is adjacent over hypotenuse. Because the adjacent side has a length of r and the hypotenuse has length q, we know that cos y must be r/q.

Hope this helps!

How does the graph of f(x) = (x − 8)3 + 4 compare to the parent function g(x) = x3?

USPshnik [31]

Answer:

Hi there!

The difference between f(x) = 3(x-8) +4 and its parent function is: the function has been shifted right eight units and shifted up four units.

Step-by-step explanation:

---anytime there is a number within a parenthesis for example (x-a) or (x+a) means there is a horizontal shift

*subtracting means you shift to the right, adding means you shift to the left.

----The number outside of the parenthesis for example (x)+a or (x)-a means there is a vertical shift

*subtracting means you are shifting down, adding means you are shifting up

On a snow day, Nolan created two snowmen in his backyard. Snowman A was built to a height of 31 inches and Snowman B was built t

ratelena [41]

Answer:

An equation for each situation

A = 31 - 4t

B = 52 - 7t

The interval of time, t,, when Snowman A is taller than Snowman B is t > 7 hours i.e

The interval of time, t, when Snowman A is taller than Snowman B is from

7.01 hours and above.

Step-by-step explanation:

Let t represent the number of hours at which the snow melts

Let A represent the height of Snowman A t hours after sunrise

Let B represent the height of Snowman B tt hours after sunrise.

An equation for each situation

A = 31 - 4(t)

B = 52 - 7(t)

The interval of time, t, when Snowman A is taller than Snowman B.

A > B

31 - 4t > 52 - 7t

Collect like terms

-4t + 7t > 52 - 31

3t > 21

t > 21/3

t > 7

This means after 7 hours, Snowman A is taller Snowman B

The interval of time, t, when Snowman A is taller than Snowman B is from

7.01 hours and above.
