Answer:

Step-by-step explanation:

B represents a union. All numbers between -2.5 and 2 satisfy two different requirements: x > -2.5 AND x < 2.

A represents an intersection x < -2.5 OR x > 2

X - m = p + n solve for x

Eva8 [605]

<em><u>Answer: ⇒ x=m+n+p</u></em>

____________________________________________________

Step-by-step explanation:

First you had to add by m from both sides of equation.

$-m+x+m=n+p+m$

$x=m+n+p$

Given: KLMN is a trapezoid, KL = MN

Lina20 [59]

Answer:

m∠LNK = 86.8°

Step-by-step explanation:

∵ LH ⊥ KN at H

∵ LK = MN

∵ LM = 3

∴ HN = (13 - 3) ÷ 2 + 3 = 8 ⇒ isosceles trapezium

∵ LN = 89

∴ LH = √(89² - 8²) = 88.64

∵ KH = (13 - 3) ÷ 2 = 5 ⇒ isosceles trapezium

∵ tan ∠LKN = LH/KH = 88.64/5

∴ m∠LKN = 86.77° ≅ 86.8°

Use l'Hôpital's Rule to find the following limit. ModifyingBelow lim With x right arrow 0StartFraction 3 sine (x )minus 3 x Ove

steposvetlana [31]

Answer:

$\lim_{x \to 0} \frac{3sinx-3x}{7x^3}=-\frac{1}{14}$

Step-by-step explanation:

The limit is:

$\lim_{x \to 0} \frac{3sinx-3x}{7x^3}=\frac{0}{0}$

so, you have an indeterminate result. By using the l'Hôpital's rule you have:

$\lim_{x \to 0} \frac{a(x)}{b(x)}= \lim_{x \to 0} \frac{a'(x)}{b'(x)}$

by replacing, and applying repeatedly you obtain:

$\lim_{x \to 0} \frac{3sinx-3x}{7x^3}= \lim_{x \to 0}\frac{3cosx-3}{21x^2}= \lim_{x \to 0}\frac{-3sinx}{42x}= \lim_{x \to 0}\frac{-3cosx}{42}\\\\ \lim_{x \to 0} \frac{3sinx-3x}{7x^3}=\frac{-3cos0}{42}=-\frac{1}{14}$

hence, the limit of the function is -1/14

Circles M and K are congruent, QR is congruent to LN and OP is congruent to VW. Find x and y.

nexus9112 [7]

Given, arc QR is congruent to arc LN and arc OP is congruent to arc VW.

And the expressions for each arc in the diagram also given as:

Arc QR = 2x - y, arc LN = 11 , arc OP= 10 and arc VW=5x+y.

Hence, we will get the system of equations as following:

Arc QR = Arc LN

2x - y = 11 ...(1)

Arc OP = Arc VW

5x + y = 10 ...(2)

Next step is to add the two equation to eliminate y so that we can solve the equations for x. Therefore,

2x+5x = 11 + 10

7x = 21

$\frac{7x}{7} =\frac{21}{7}$ Divide each sides by 7.

So, x= 3

Now plug in x=3 in equation (2) to get the value of y.

5(3) + y = 10

15 + y =10

15 + y - 15 = 10 - 15 Subtracting 15 from each sides.

y = -5

So, x=3 and y =-5
