Toilet rolls are sold in packs of 4.

How many toilet rolls are there in 9 packs?​

Answer:

Please check explanations

Step-by-step explanation:

Using the difference of two squares, the lowest common multiple becomes;

1-sin^2 a

Thus, we have that;

cos a (1-sin a) + cos a (1 + sin a) /1 - sin^2 a

1 - sin^2 a = cos^2 a

That means;

{cos a - cos a sin a + cos a + cos a sin a}/ cos^2 a

= 2cos a / cos^2 a

= 2/cos a

but 1/cos a = sec a

Thus;

2/ cos a = 2 sec a

Answer:

a)  cosθ  = [tex]\frac{-2\sqrt{85} }{85}[/tex]

Step-by-step explanation:

Step(i):-

Given point ( x , y ) = ( - 2 , 3 )

We know that the polar co-ordinates

  x = r cos θ and y = r sinθ

where   [tex]r = \sqrt{x^{2} +y^{2} }[/tex]  

            [tex]r = \sqrt{(-2)^{2} +(9)^{2} } = \sqrt{4+81} = \sqrt{85}[/tex]

Step(ii):-

           x = r cos θ

          cosθ   [tex]= \frac{x}{r}[/tex]

      cosθ  = [tex]\frac{-2}{\sqrt{85} } = \frac{-2}{\sqrt{85} } X \frac{\sqrt{85} }{\sqrt{85} }[/tex]

       cosθ  = [tex]\frac{-2\sqrt{85} }{85}[/tex]

Answer: 2x +3y ≤ 12

Step-by-step explanation:

Given: Lynn's mom has 12 eggs to use for this purpose..

i.e. she can use maximum 12 eggs.

A batch of cookies requires two eggs and a batch of brownies requires 3 eggs.

Let x= Number of batches of cookies , y= Number of batches of brownies

Then, 2x +3y ≤ 12 (maximum eggs = 12)

hence, the required inequality :  2x +3y ≤ 12

The possible values of the expression 2 - a are -5, -6, and -7.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

To find all possible values of the expression 2 - a, we need to use the information that is given in the inequality 6 < a < 10.

We know that a is a value between 6 and 10, but not equal to 6 or 10. So, we can substitute each of the values between 6 and 10 (excluding 6 and 10) into the expression 2 - a and find the result.

We can start with the smallest possible value for a, which is 6 + 1 = 7.

So, 2 - 7 = -5

Next, we can use the value of a = 8,

so, 2 - 8 = -6

And, we can use the value of a = 9,

so, 2 - 9 = -7

Therefore, the possible values of the expression 2 - a are -5, -6, and -7.

Answer:

0

Step-by-step explanation:

tan0 •sin 0+ cot0 •sin0 =

tan(0) • sin(0) + cot(0) • sin(0) =

(tan(0) × sin(0)) + (cot(0) × sin(0)) =

(0 × 0) + (0 × 0) = 0 + 0 = 0

Step-by-step explanation:

Answer:

87.5%

Step-by-step explanation:

The answer would be 87.5 because there are a total of 26 students and 14 of them like chocolate. So, you would set up the fraction of 14/26 and x/100. You would then multiply 14 times 100 and divide that by 26. The answer would be 87.5. And that would be 87.5%.

[tex]\boxed{\boxed{\pink{\bf \leadsto Hence \ the\ correct \ option \ is \ B \ \bigg\{ x | x \in R , x \leq 7\dfrac{5}{6}\bigg\} }}}[/tex]

A inequality is given to us and we need to find the solution set . The inequality given to us is :-

[tex]\bf \implies x - 6\dfrac{1}{3} \leq 1\dfrac{1}{2} \\\\\bf\implies x \leq 6\dfrac{1}{3} + 1\dfrac{1}{2} \\\\\bf\implies x \leq \dfrac{19}{3} + \dfrac{3}{2}\\\\\bf\implies x \leq \dfrac{38+9}{6} \\\\\bf\implies x \leq \dfrac{47}{6} \\\\\bf\implies\boxed{\red{\bf x \leq 7\dfrac{5}{6}}} [/tex]

This means that x belongs to Real Numbers. Hence final answer would be :-

[tex]\boxed{\red{\bf \bigg\{ x | x \in R , x \leq 7\dfrac{5}{6}\bigg\}}}[/tex]

The equation of the line that goes through points (1,1) and (3,7) is [tex]\mathbf{y=3x-2}[/tex]

Step-by-step explanation:

Determine the equation of the line that goes through points (1,1) and (3,7)

We can write the equation of line in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding Slope

Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=1, y_1=1, x_2=3, y_2=7[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{7-1}{3-1}\\Slope=\frac{6}{2}\\Slope=3[/tex]

We get Slope = 3

Finding y-intercept

y-intercept can be found using point (1,1) and slope m = 3

[tex]y=mx+b\\1=3(1)+b\\1=3+b\\b=1-3\\b=-2[/tex]

We get y-intercept b = -2

So, equation of line having slope m=3 and y-intercept b = -2 is:

[tex]y=mx+b\\y=3x-2[/tex]

The equation of the line that goes through points (1,1) and (3,7) is [tex]\mathbf{y=3x-2}[/tex]

Step-by-step explanation:

Answer:

[tex]\sin \left(90^{\circ \:}-x\right)=\cos \left(x\right)[/tex]

Hence, option D is correct.

Step-by-step explanation:

Given the expression

[tex]sin\:\left(90^{\circ }\:-\:x\right)[/tex]

Using the angle difference identity

[tex]\sin \left(s-t\right)=\sin \left(s\right)\cos \left(t\right)-\cos \left(s\right)\sin \left(t\right)[/tex]

so the expression becomes

[tex]sin\:\left(90^{\circ }\:-\:x\right)=\sin \:\left(90^{\circ \:\:}\right)\cos \:\left(x\right)-\cos \:\left(90^{\circ \:\:}\right)\sin \:\left(x\right)[/tex]

as sin 90° = 1

so sin 90° cos x = cos x

also

cos 90° = 0

so con (90°) sin x = 0

Thus, the expression becomes

[tex]\sin \:\left(90^{\circ \:\:}\right)\cos \:\left(x\right)-\cos \:\left(90^{\circ \:\:}\right)\sin \:\left(x\right)=\cos \:\left(x\right)-0[/tex]

                                                           [tex]= cos (x)[/tex]      ∵ [tex]\cos \left(x\right)-0=\cos \left(x\right)[/tex]

Therefore,

[tex]\sin \left(90^{\circ \:}-x\right)=\cos \left(x\right)[/tex]

Hence, option D is correct.
