Let's recall that , the equation of line that passes through the point [tex]{\bf (x_{1},y_{1})}[/tex] and has a slope m is [tex]{\bf y-y_{1}=m(x-x_{1})}[/tex]

Now using the same concept in our question , we have ;

[tex]{:\implies \quad \sf Y-(-1)=-3(x-2)}[/tex]

[tex]{:\implies \quad \sf Y+1=-3x+6}[/tex]

[tex]{:\implies \quad \sf Y=-3x+6-1}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{Y=-3x+5}}}[/tex]

Hence , Option B) Y = -3x + 5 is correct :D

Answer:

In line 4, he did the mistake. He should have square rooted the other side as changing sides changes square to square root.

explanation:

line 1:   [tex]\sf p^2 - 10p - 11 = 0[/tex]

[tex]\sf p^2 - 10p = 11[/tex]

line 2:   [tex]\sf p^2 - 10p + 25 = 11 + 25[/tex]

[tex]\sf p^2 - 5p -5p+ 25 = 36[/tex]

[tex]\sf p(p-5)-5(p-5) = 36[/tex]

line 3:   [tex]\sf (p-5)^2 = 36[/tex]

line 4:   [tex]\sf p - 5 = \pm \sqrt{36}[/tex]

[tex]\sf p-5 = 6[/tex]   or   [tex]\sf p-5 = -6[/tex]

line 5: [tex]\sf p = 11[/tex]  or   [tex]\sf p = -1[/tex]

line 6: The solution is p = 11 or p = -1

Answer:

x = 3

Step-by-step explanation:

This is a slightly special case because x = 4. That means that there is no slope to the line.

Since our parallel line goes through the point (3, 4) the equation will be x = 3 to "match" the slope, or lack of, to the original line.

area = l x w

w = area : l

w = 5.612 x 10¹⁴ : 9.2 x 10⁷

w = 6.1 x 10⁶

the perimeter: 2(l+w)

= 2(9.2 x 10⁷ + 6.1 x 10⁶)

=1.84 x 10⁸ + 1.22 x 10⁷

=10⁷(18.4+1.22)

= 1.962 x 10⁸ cm

Answer:

P = 2.0 × 10⁸ cm

Step-by-step explanation:

5.612 × 10¹⁴ = 9.2 × 10⁷ · x

6.1 × 10⁶ = x
9.2 × 10⁷ + 9.2 × 10⁷ + 6.1 × 10⁶ + 6.1 × 10⁶ = 1.962 × 10⁸ cm

Answer:

(a) Independent variable:  b (number of bags sold)

    Dependent variable:  p(b)  (profit)

(b) 25

(c) 84700

(d) 70

(e) b < 25

Step-by-step explanation:

(a) Independent variable:  b (number of bags sold)

    Dependent variable:  p(b)  (profit)

(b) To break even, set p(b) to zero and solve for b:

⇒ 350b - 8750 = 0

⇒ 350b = 8750

⇒ b = 8750 ÷ 350

⇒ b = 25

(c) Substitute b = 267 into equation and solve for p(b):

⇒ 350(267) - 8750 = 84700

(d) Set p(b) to 15750 and solve for b:

⇒ 350b - 8750 = 15750

⇒ 350b = 15750 + 8750

⇒ 350b = 24500

⇒ b = 24500 ÷ 350

⇒ b = 70

(e) If she breaks even when she sells 25 bags, if she sells less than 25 bags she will have a negative profit. So b < 25

Answer:

[tex]2\sin(\theta)[/tex]

Step-by-step explanation:

[tex]\csc(\theta)=\dfrac{1}{\sin(\theta)}[/tex]

[tex]\sin^2(\theta)+\cos^2(\theta)=1\implies \sin^2(\theta)=1-\cos^2(\theta)[/tex]

[tex]2\csc(\theta)- 2cos^2(\theta)\times csc(\theta)[/tex]

[tex]=\dfrac{2}{\sin(\theta)}-\dfrac{ 2cos^2(\theta)}{\sin(\theta)}[/tex]

[tex]=\dfrac{ 2[1-cos^2(\theta)]}{\sin(\theta)}[/tex]

[tex]=\dfrac{ 2sin^2(\theta)}{\sin(\theta)}[/tex]

[tex]=2\sin(\theta)[/tex]

[tex]\\ \rm\Rrightarrow 2cscA-2cos^2A(cscA)[/tex]

[tex]\\ \rm\Rrightarrow 2(1/sinA)-2cos^2A(1/sinA)[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{2}{sinA}-\dfrac{2cos^2A}{sinA}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{2-2cos^2A}{sinA}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{2(1-cos^2A)}{sinA}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{2sin^2A}{sinA}[/tex]

[tex]\\ \rm\Rrightarrow sinA[/tex]

Answer:

C

Step-by-step explanation:

the equation of relationship between x and y in item ll is: y = -x -3

the rate of change of it is -1 that is equal to the rate of change of items l.

Answer:

r = [tex]\frac{12\pi }{\pi }[/tex] / 2 = 6

volume = 1/3 * π * r² * h

h = 3 * V/π * [tex]r^{2}[/tex]

h = [tex]\frac{3 * 264\pi }{\pi * 6^{2} }[/tex] = 22

The height of the right cone is 22 units.

'A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.'

According to the given problem,

Radius of the right cone = [tex]\frac{\frac{12\pi }{\pi } }{2}[/tex]

                                         = 6 units

Volume of the right cone = [tex]\frac{\pi r^{2}h }{3}[/tex]

Solving for h,

       h =  [tex]\frac{3*264\pi }{\pi *6^{2} }[/tex]

   ⇒ h = 22 units

Hence, we can conclude that the height of the right cone is 22 units.

Answer: y=-2x+6

Step-by-step explanation:

[tex]m=\frac{6-2}{0-2}=\frac{4}{-2}=-2[/tex]

So [tex]y=2x+b[/tex]. We can substitute (0, 6) to get:

6 = 2(0)+b

b=6.

Meaning y=-2x+6.

2(8a + 5)

Step-by-step explanation:

Hi there!

16a + 10

The two terms here are 16a and 10. Both of them are divisible by 2. Factor 2 out of the terms:

= 2(8a + 5)

Now, there are no more common factors between 8a and 5. Therefore, this expression is now fully factored.

Answer/Step-by-step explanation:

A double prime is a symbol used to distinguish a third quantity x^('') ("x double prime") from two other related quantities x and x^' ("x prime). Double primes are most commonly used to denote transformed coordinates, conjugate points, and derivatives. A double prime is also used to denote the number of arc seconds in an angle measure, or the number of inches in a length.
