Answer: x^3 + 2x^2

Explanation:

when we divide polynomial x^3 +3x^2 +x  by  x+2

we will first consider polynomial  with  one degree less than the numerator that will  be x^{2} and as when we multiply x^{2} by x+2 by the rule of long division we get x^3 +2x^2

Hence, x^3 +2x^2  will be the first term we will divide from the dividend.

use a numerical method to estimate the value of the limit (if it exists.) Lim e^5t -1 /t as x tends to 0 from both sides​
charle [14.2K]

Hello from MrBillDoesMath!

Answer:

5

Discussion:

Consider the expansion of e^x:

e^x = 1 + x + x^2/2 + x^3/6 +......            =>      replace x by 5t

e^(5t) = 1 + (5t)  + (5t)^2/2 + ....              =>      subtract 1 from both sides

e^(5t) - 1 = (5t) + (5t)^2/2+....                  =>      divide both sides by t

(e^(5t) -1)/ t = 5 + (25/2)  t +....

so as t ends to 0  the quotient tends to    

5 + (25/2)0 + (other terms) *0   ->   5

Thank you,

MrB

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 36 m, Find t
Korvikt [17]

Applying the Pythagorean theorem, the height of the building is: 24.9 m.

<h3>How to Apply the Pythagorean Theorem?</h3>

Where c is the length of the hypothenuse of a right triangle, and a and b are the legs of the right triangle, the Pythagorean theorem states that:

c = √(a² + b²).

The diagram of the building and its shadow form a right triangle as shown in the image below, where:

a = height of the building

b = 26

c = 36

Applying the Pythagorean theorem, we will have:

a = √(36² - 26²)

a = √(36² - 26²)

a = 24.9 m
