<h3>________________________________________________</h3>

<u>Step by Step Solution for Part-1:</u>

<u>We know that:</u>

  • The successor of a number defines one to be added to a number
  • The predecessor of a number defines one being subtracted to a number

<u>Solution:</u>

  • ⇒ (-5 + 1) + (6 - 1)
  • ⇒ (-4) + (5)
  • ⇒ 1
<h3>________________________________________________</h3>

<u>Step by Step Solution for Part-2:</u>

<u>We know that:</u>

  • b - 1 = a
  • To solve: a - b

<u>Solution:</u>

  • ⇒ a - b
  • ⇒ (b - 1) - b
  • ⇒ (-b + 1) + b
  • ⇒ -b + 1 + b
  • ⇒ 1
<h3>________________________________________________</h3>

<u>Step by Step Solution for Part-3:</u>

  • (42 - 66) - (100 - 24)
  • => (-24) - (76)
  • => -100

#1

  • Successor of -5=-4
  • Predecessor of 6=5

\\ \tt\hookrightarrow -4+5=1

#2

  • Let one be x and other be x-1

\\ \tt\hookrightarrow a-b=x-x+1=+1

#3

\\ \tt\hookrightarrow 42-66-(100-24)

\\ \tt\hookrightarrow -24-76

\\ \tt\hookrightarrow -100

Csc x= -√2 for π≤x≤3π/2
love history [14]

Answer:

A

Step-by-step explanation:

We can write this as Sinx by "flipping" the -\sqrt{2}.

So we will have:  Sin(x)=-\frac{1}{\sqrt{2} }

From basic trigonometry, we know the value of  \frac{1}{\sqrt{2}}  of sine is of the angle \frac{\pi}{4}

<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and  \frac{3\pi}{2}, <em>so we disregard 4th quadrant.</em>

<em />

<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>

\frac{\pi}{4}+\pi\\=\frac{\pi +4\pi}{4}\\=\frac{5\pi}{4}

A is the right answer.

Are -4 ( x - 6) and -4 • x - 4 • 6 equivalent
tekilochka [14]

Answer:

 no

Step-by-step explanation:

Lets solve the first half.

-4 ( x - 6) = -4x + 24

Second one:

-4 times x - 4 times  6 = -4x -24

Now compare.....Not the same right??

So your answer is:  no

Hope this helps :)

Help pls..................
Triss [41]

Answer:

Area = 152ft²

Step-by-step explanation:

Simpifly:

A = 13(13-6) + 9(13-6)

A = 13(7) + 9(7)

A = 22(7)

A = 22(7)

A = 20(7)+2(7)

A = 140 + 14

A = 152

Please help me with this please and thank you
Alina [70]

Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

so, the fitting equation is

y = 2x² + 1
