36 and 38<br><br>Steps and explaination please

Answer:

36. Limit = 2/3.

Step-by-step explanation:

36.

(∛ x- 1) / (√x - 1)

Rationalise the expression:-

Multiply top and bottom by (√x + 1):-

(∛x - 1)(√x + 1) / (√x - 1)(√x + 1)

= x^5/6 + ∛x - √x - 1 / (x - 1)

Applying L'hopital's rule ( differentiating top and bottom of the fraction) we have:

Limit as x ----> 1 of [5/6 x^-1/6 + 1/3 x^(-2/3) - 1/2x^-1/2] / 1

= 5/6(1) + 1/3(1) - 1/2(1) = 2/3 (answer).

Which of the following statements are the same? (A) x -= x + 4 (B) x = x + 4 - x (C) x = x - (x + 4) (A) and (B) are the same (A

Nesterboy [21]

Answer: (A) and (B) are the same

Step-by-step explanation:

for (A)

x-=x+4

x=x-(x+4)

x=x-x-4

x=4

for (B)

x=x+4-x

x=4

for (C)

x=x-(x+4)

x=x-x-4

x=-4

so (A) and (B) are the same because the value of their x is +4

The base of a solid oblique pyramid is an equilateral triangle with an edge length of s units.

Assoli18 [71]

Answer:

Option B is correct.i.e.,

Step-by-step explanation:

Given: Pyramid with equilateral triangle as base

Length of side of equilateral triangle = s unit

to find: height of equilateral triangle

Here we use a property of equilateral triangle.

Perpendicular from a vertex on a side and median of that side of a triangle is same in equilateral triangle.

All heights are of equal length. So, we just need to find one height or length of 1 altitude.

Figure of base triangle is attached

In Δ ABC

AB = BC = AC = s unit

AD is height

BD = $\frac{BC}{2}\:=\:\frac{s}{2}\:units$

Now, In Δ ABD

using pythagoras theorem

BD² + AD² = AB²

$(\frac{s}{2})^2+AD^2=s^2$

$\frac{s^2}{4}+AD^2=s^2$

$AD^2=s^2-\frac{s^2}{4}$

$AD^2=\frac{4s^2-s^2}{4}$

$AD^2=\frac{3s^2}{4}$

$AD=\sqrt{\frac{3s^2}{4}}$

$AD=\frac{\sqrt{3}s}{2}$

$AD=\frac{s}{2}\sqrt{3}$

Therefore, Option B is correct.i.e., $\frac{s}{2}\sqrt{3}$
