Naomi's bill for breakfast at a restaurant was $82.She left a15% tip.What was the amount of the tip?

Answer:

distributive property says x(a+b)

= xa+xb

so 5(n-3)

= 5n-15

Answer: 5n-15

Step-by-step explanation: 5(n-3). multiply n by 5 and -3 by 5 to get 5n-15

a) The piecewise function is:

[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]

[tex]C(n) = 15 + 1.1n, n > 20[/tex]

b) Applying the piecewise function, it is found that it will cost $40.

A piecewise function is a function that has different definitions based on the input.

Item a:

[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]

[tex]C(n) = 15 + 1.1n, n > 20[/tex]

Then, the piece-wise function is:

[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]

[tex]C(n) = 15 + 1.1n, n > 20[/tex]

Item b:

Then:

[tex]C(20) = 12 + 1.4(20) = 12 + 28 = 40[/tex]

It will cost $40.

[tex]99\sqrt{15} \thickapprox \:383.42535[/tex]

Step-by-step explanation:

[tex]11\sqrt{1215}[/tex]

Factor [tex]1215[/tex] [tex]=9^{2} \times 15[/tex]. Rewrite the square root of the product [tex]\sqrt{9^{2} } \sqrt{15}[/tex], than take the square root of [tex]9^{2}[/tex].

[tex]11\times 9\sqrt{15}[/tex]

Multiply 11 and 9 which will give you 99.

[tex]99\sqrt{15}[/tex]

Step-by-step explanation:

[tex]\large\underline{\sf{Solution-}}[/tex]

[tex]\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]

Let assume that

[tex]\rm :\longmapsto\:y = {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]

We know,

[tex]\boxed{\tt{ {cosec}^{ - 1}x = {sin}^{ - 1}\bigg( \dfrac{1}{x} \bigg)}}[/tex]

So, using this, we get

[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2x}{1 + {x}^{2} } \bigg)[/tex]

Now, we use Method of Substitution, So we substitute

[tex] \red{\rm :\longmapsto\:x = tanz \: \rm\implies \:z = {tan}^{ - 1}x}[/tex]

So, above expression can be rewritten as

[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2tanz}{1 + {tan}^{2} z} \bigg)[/tex]

[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( sin2z \bigg)[/tex]

[tex]\rm\implies \:y = 2z[/tex]

[tex]\bf\implies \:y = 2 {tan}^{ - 1}x[/tex]

So,

[tex]\bf\implies \: {cosec}^{ - 1}\bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = 2 {tan}^{ - 1}x[/tex]

Thus,

[tex]\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]

[tex]\rm \:  =  \: \dfrac{d}{dx}(2 {tan}^{ - 1}x)[/tex]

[tex]\rm \:  =  \: 2 \: \dfrac{d}{dx}( {tan}^{ - 1}x)[/tex]

[tex]\rm \:  =  \: 2 \times \dfrac{1}{1 + {x}^{2} } [/tex]

[tex]\rm \:  =  \: \dfrac{2}{1 + {x}^{2} } [/tex]

Hence,

[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ \dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = \frac{2}{1 + {x}^{2} }}}}[/tex]

Hence, Option (d) is correct.

Answer:

[tex] - 23x(x + 3) \\ { - 23x}^{2} - 69x \\ \\ \\ \\ \\ \\ hope \: it \: helps \\ stay \: safe \: healthy \: nd \:and \: happy[/tex]

Answer:

[tex]-23x^{2} -69x[/tex]

Step-by-step explanation:

Using the distributive property:

[tex]-23x(x+3)[/tex]

You will multiply both the x and the 3 inside the parantheses by the -23x outside.

[tex]-23x[/tex] · [tex]x = -23x^{2}[/tex]

Then:

[tex]-23x[/tex] · [tex]3 = -69x[/tex]

If you combine both you will recieve:

[tex]-23x^{2} -69x[/tex]

Answer:

x = 9.47 degrees  ( in first quadrant.

Step-by-step explanation:

sin2x + sinx cos x = 1/2

Now sinx cos x = 1/2sin2x so:

3/2sin2x = 1/2

sin2x = 1/2 / 3/2

sin2x = 1/2 * 2/3 = 1/3

2x = arcsin 1/3 = 19.47 degrees

x = 9.74 degrees to nearest hundredth.

Answer:

280 men; 80 women.

Step-by-step explanation:

this task can be solved used system of two equation (note, it is not the only and shortest way):

1) if number of men is 'm', women is 'w' and ratio is 7:2, then it is possible to write the first equation: m/w=7/2;

if together there are 360, then it is possible to write the second equation of the system: m+w=360.

2) after item 1 it is possible to make up and solve the system:

[tex]\left \{ {{m/w=7/2} \atop {m+w=360}} \right. \ => \ \left \{ {{7w=2m} \atop {m+w=360}} \right. \ => \ \left \{ {{m=280} \atop {w=80}} \right.[/tex]
