numerical answers expected/only whole numbers

Answer:

Question 1: Option B

Question 2: Option A

Step-by-step explanation:

Question #1:

Options are:

10¹¹ = 100000000000

10¹⁴ = 100000000000000

10¹⁵ = 1000000000000000

10¹² = 1000000000000

The power that exceeds the given quantity would be:

10¹⁴ ⇒ There are more digits.

Question #2:

We have the following expression:

981 44/51 = 61*981+44/61 = 981.72

We have to 10³ = 1000
So, the correct option is 10³

Answer:

Whenever finding a rule, figure out what x+1 relates to in terms of y (aka the slope). Also, figure out the y-intercept (0,y)

Example:

x+1 = y+2.

Slope: 2 ÷ 1 = 2.

The y-intercept is (0,9)

This would make the rule y=2x+9

Answer:

1. y=x 2. y=x-2 3. y=2x+10 4. y=5x 5. y= x+21

Answer:

A

Step-by-step explanation:

In this example, Emily is adding 9 to both sides of the equation. Doing so keeps the equation equal since the operation was done to both sides, so this must be the addition property of equality.

Given:

radius(R) = 12 units

arc = 134°

Find: area of sector

Plan: if you think about it, a sector area is a fractional part of the full area of the circle. It’s a pie piece.

A(circle) = π R^2

134° is 134°/360° = 67/180 That is 67/180 th of the full circle

area (S) = 67/180 (π R^2)

S = 67/180 (π )(12^2) = 67/180(144 π) = 54 π units^2 or

≈ 54(3.1416) ≈ 168.389 units^2

Double Check: ✅ ✅

Answer: 18 π units^2 or 168.39 units^2 approximately

The required trigonometric identity is 1/2[sin(x + y) - sin(x - y)] = cosxsiny

To answer the question, we need to know what trigonometric identities are

Trigonometric identities are relationships between the trigonometic ratios.

Since we require cosxsiny

Given that

So, subtracting both expressions, we have

sin(x + y) - sin(x - y) = sinxcosy + cosxsiny - (sinxcosy - cosxsiny)

= sinxcosy + cosxsiny - sinxcosy + cosxsiny

= sinxcosy - sinxcosy + cosxsiny  + cosxsiny

= 0 + 2cosxsiny

= 2cosxsiny

sin(x + y) - sin(x - y) = 2cosxsiny

Dividing through by 2, we have

1/2[sin(x + y) - sin(x - y)] = cosxsiny

So, the required trigonometric identity is 1/2[sin(x + y) - sin(x - y)] = cosxsiny

(y+2) / y

Step-by-step explanation:

Just do what is says     f(x ) = (y+2) / y

Answer:

x=13

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    (2*x+14)-((3*x+1))=0

1.1      Solve  :    -x+13 = 0

Subtract  13  from both sides of the equation :

                     -x = -13

Multiply both sides of the equation by (-1) :  x = 13

Answer:

vertex = (0, -4)

equation of the parabola:  [tex]y=3x^2-4[/tex]

Step-by-step explanation:

Given:

Vertex form of a parabola:  [tex]y=a(x-h)^2+k[/tex]

(where (h, k) is the vertex and [tex]a[/tex] is some constant)

Substitute point (0, -4) into the equation:

[tex]\begin{aligned}\textsf{At}\:(0,-4) \implies a(0-h)^2+k &=-4\\ah^2+k &=-4\end{aligned}[/tex]

Substitute point (-2, 8) and [tex]ah^2+k=-4[/tex] into the equation:

[tex]\begin{aligned}\textsf{At}\:(-2,8) \implies a(-2-h)^2+k &=8\\a(4+4h+h^2)+k &=8\\4a+4ah+ah^2+k &=8\\\implies 4a+4ah-4&=8\\4a(1+h)&=12\\a(1+h)&=3\end{aligned}[/tex]

Substitute point (1, -1) and [tex]ah^2+k=-4[/tex] into the equation:

[tex]\begin{aligned}\textsf{At}\:(1.-1) \implies a(1-h)^2+k &=-1\\a(1-2h+h^2)+k &=-1\\a-2ah+ah^2+k &=-1\\\implies a-2ah-4&=-1\\a(1-2h)&=3\end{aligned}[/tex]

Equate to find h:

[tex]\begin{aligned}\implies a(1+h) &=a(1-2h)\\1+h &=1-2h\\3h &=0\\h &=0\end{aligned}[/tex]

Substitute found value of h into one of the equations to find a:

[tex]\begin{aligned}\implies a(1+0) &=3\\a &=3\end{aligned}[/tex]

Substitute found values of h and a to find k:

[tex]\begin{aligned}\implies ah^2+k&=-4\\(3)(0)^2+k &=-4\\k &=-4\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]\implies y=3(x-0)^2-4=3x^2-4[/tex]

So the vertex of the parabola is (0, -4)

It can be solved through some shortcut tricks of parabola

It passes through (-2,8) and (1,-1)

The minimum equation of the parabola (as it's quadratic) for vertex at (0,0)

whatever our required parabola be it's translated from the above one

So

Let a be 0

So it has vertex as well as y inetrcept at (0,0)

For x=-2

For x=1

It wasn't negative but in translation it's negative so something is subtracted

Take a =2 and subtract (-2)² i.e 4 as it's minimal value of y=x² where x≠y

For

(-2,8)

No try a=3

Yes satisfied

Take (1,-1)
