The cost of purchase of the employee for a shirt worth $46.99 is $42.30 .

In the question , It is given that

amount of discount  employee receives = 10%

Price of the shirt = $46.99        ...(i)

amount of discount the employee got for the shirt = 10% of 46.99

= 0.10*46.99             ...(as 10%=0.10 )

= 4.699           ...(ii)

So the amount of discount the employee got for the shirt = $4.699

The cost of purchase = Price of shirt - discount

Substituting the values from equation (i) and equation (ii) we get,

cost of purchase = 46.99 - 4.699

= 42.291

≅ 42.30

Therefore , the cost of purchase of the employee for a shirt worth $46.99 is $42.30 .

The velocity of the particle, in meters per second is 0.78 m/s

The position function is given as:

x(t) = e-(t - 3)2

Rewrite properly as

x(t) = e^-(t - 3)^2

Next, we differentiate the above function to determine the velocity function.

Using a graphing calculator, we have:

x'(t) = -2(t - 3) * e^-(t - 3)^2

At t = 2.5 s, we have:

x'(2.5) = -2(2.5 - 3) * e^-(2.5 - 3)^2

Evaluate

x'(2.5) = 0.78

Hence, the velocity of the particle, in meters per second is 0.78 m/s

Answer:

12/6 but if you simplify it's 2

Step-by-step explanation:

4+8 = 12

6-3 = 3

2 x 3 = 6

12/6 = 2

x = 1, y = -1 and z = -2.

Here, we are given 3 equations-

4x+12y+4z = -16 ...(1)

12x-12y+8z = 8   ...(2)

4x+12y-4z = 0    ...(3)

Firstly, we add equations 1 and 2, we get,

4x + 12y + 4z + 12x - 12y + 8z = -16 + 8

16x + 12z = -8

4x + 3z = -2 ...(4)

Adding 2 and 3, we get,

12x - 12y + 8z + 4x + 12y - 4z = 8

16x + 4z = 8

4x + z = 2 ...(5)

Now, subtracting equation 4 from 5, we get-

4x + z - 4x - 3z = 2 + 2

-2z = 4

z = 4/-2

z = -2

Thus, 4x - 2 = 2

4x = 4

x = 4/4

x = 1

and 4(1) + 12y + 4(-2) = -16

4 + 12y -8 = -16

12y = -16 + 4

12y = -12

y = -12/12

y = -1

Thus, x = 1, y = -1 and z = -2.

Step-by-step explanation:

We need to calculate the surface square of the cylinder. The formula for that is S=2*pi*r*(r+h). r is radius of the cylinder which is diameter/2=3/2=1.5. The formula becomes: S=2*pi*1.5(1.5+11)=37.5pi=~117.5 which is approximated to 118 since if the decimal you're approximating is 5 or higher it just increments the previous one, so here we just add 1 to 117

The coordinates of point P on the number line are 16 or 21.

In this question we find a line segment set on a number line and whose endpoints and segment ratio are known. Then, we can determine the location of the point P by using the line segment formula:

P(x) = A(x) + k · [B(x) - A(x)]

Where k is the partition ratio.

If we know that A(x) = 6, B(x) = 31 and k = 3 / 5, then the location of the point P is:

P(x) = 6 + (3 / 5) · (31 - 6)

P(x) = 6 + (3 / 5) · 25

P(x) = 6 + 15

P(x) = 21

P(x) = 6 + (2 / 5) · (31 - 6)

P(x) = 6 + (2 / 5) · 25

P(x) = 6 + 10

P(x) = 16

Answer:

The function is exponential

Its equation is [tex]y = \frac{7}{3} \cdot(\frac{1}{3} )^x[/tex]

Step-by-step explanation:

We can see that, as x increases by a constant y increases by a factor of [tex]\frac{1}{3}[/tex]

So the table represents an exponential equation

The form of the equation is [tex]a\cdot(\frac{1}{3})^{x}[/tex]

All we have to do is determine a

Take the entry for x = 0

At x = 0, the equation becomes y = [tex]a\cdot(\frac{1}{3}) ^ 0[/tex]

Any number raised to the power 0 is 1

So at [tex]x = 0, y = a\cdot1 = a[/tex]

But we know the y value at x = 0 is [tex]\frac{7}{3}[/tex]

So [tex]a = \frac{7}{3}[/tex]

The equation of the function is

[tex]y = \frac{7}{3} \cdot(\frac{1}{3} )^x[/tex]  

We can verify by plugging in a few values for x into the above equation and seeing if the corresponding calculated values concur with the one in the table

For [tex]x = - 1, y = \frac{7}{3}\cdot (\frac{1}{3})^{-1} = \frac{7}{3}\cdot 3 = 7[/tex]

You can try the other x values and see that computed and given y values concur

We are given that the side of the regular pentagon = 2 x + 9

So, the perimeter will be:

P ( Regular pentagon) = 5 × ( 2 x + 9 )

P ( Regular pentagon) = 10 x + 45

Also, we are given that the side of a square is 3 x

Perimeter will be:

P ( square) = 4 × 3 x

P ( square) = 12 x

Now, we are given that P ( Regular pentagon) = P ( square)

So, we get that:

10 x + 45 = 12 x

12 x - 10 x = 45

2 x = 45

x = 45 / 2

Step-by-step explanation:

After the expansion of the series represented by -

∑ r(r + 1)   [r = 0 to r = 5] , we can say that the -

1st term of series = 0

2nd term of series = 2

3rd term of series = 6

Last term = 30

A series is the sum of a few or all elements of the sequence in which the elements are arranged according to some specific pattern.

Given in the question is a series represented by -

∑ r(r + 1)    [r = 0 to r = 5]

We can determine any term of this series by replacing it with r. The series given to us however only contains six terms. So, we will write the complete series in numeral form and then determine the terms.

We have -

∑ r(r + 1)    [r = 0 to r = 5]

Expanding the series, we get -

∑ r(r + 1)    [r = 0 to r = 5] = (0 x 1) + (1 x 2) + (2 x 3) + (3 x 4) + (4 x 5) + (5 x 6).

∑ r(r + 1)    [r = 0 to r = 5] = 0 + 2 + 6 + 12 + 20 + 30.

Hence, the numeral form of the series with elements position is -

0 + 2 + 6 + 12 + 20 + 30.

[1]   [2]  [3]   [4]   [5]     [6]

Therefore, after the expansion of the series represented by -

Answer: Step-by-step explanation:X= number of driver that drive to work alone  the probability that at most 7 drove to work alone is equal to 1 - probability that exactly 8 drive to work alone  P(x<=7)= 1 - P(x>7) = 1- P(x=8)  Probability of driving to work alone = 0.77  Probability of not driving to work alone = 0.23Total number of workers = 8  

Step-by-step explanation:

The required probability that exactly 3 out of 8 workers drive to work alone is 0.0165.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have to find the probability that exactly 3 of the workers drive to work alone.

Using the binomial probability formula:

[tex]P(X = k) = (^nC_k) \times p^k \times (1-p)^{(n-k)}[/tex]

where X is the number of workers who drive to work alone, k is the number of successes, n is the sample size, p is the probability of success, and (n choose k) is the binomial coefficient.

As per the question, k = 3, n = 8, p = 0.77

Substitute the given values, and we get:

[tex]P(X = 3) = (^8 C_3) \times 0.77^3 \times (1-0.77)^{(8-3)}[/tex]

= 0.0165

Therefore, the probability that exactly 3 out of 8 workers drive to work alone is 0.0165.

[tex]\displaystyle \mathrm{B}(x,y) = \int_0^1 t^{x-1} (1-t)^{y-1} \, dt = \frac{\Gamma(x) \Gamma(y)}{\Gamma(x+y)}[/tex]

Consider the sum

[tex]\displaystyle S(x) = \sum_{m=1}^\infty \frac{\Gamma(m) \Gamma(x)}{\Gamma(m+x)}[/tex]

Compute it by converting the gammas to the beta integral, interchanging summation with integration, and using the sum of a geometric series.

[tex]\displaystyle S(x) = \sum_{m=1}^\infty \mathrm{B}(m,x) \\\\ ~~~~ = \sum_{m=1}^\infty \int_0^1 t^{m-1} (1-t)^{x-1} \, dt \\\\ \int_0^1 (1-t)^{x-1} \sum_{m=1}^\infty t^{m-1} \, dt \\\\ ~~~~ = \int_0^1 (1-t)^{x-2} \, dt \\\\ ~~~~ = \int_0^1 t^{x-2} \, dt \\\\ ~~~~ = \frac1{x-1} = \frac{(x-2)!}{(x-1)!} = \frac{\Gamma(x-1)}{\Gamma(x)}[/tex]

It follows that

[tex]\displaystyle S(n+x) = \sum_{m=1}^\infty \frac{\Gamma(m) \Gamma(n+x)}{\Gamma(m+n+x)} = \frac{\Gamma(n+x-1)}{\Gamma(n+x)}[/tex]

Now we compute the sum of interest. It's just a matter of introducing appropriate gamma factors to condense the double series into a single hypergeometric one.

Recall the definition of the generalized hypergeometric function,

[tex]\displaystyle {}_pF_q \left(\left.\begin{array}{c} a_1,a_2,\ldots,a_p\\b_1,b_2,\ldots,b_q\end{array}\right\vert z\right) = \sum_{n=0}^\infty \frac{(a_1)_n (a_2)_n \cdots (a_p)_n}{(b_1)_n (b_2)_2 \cdots (b_q)_n} \frac{z^n}{n!}[/tex]

where [tex](a)_n[/tex] denotes the Pochhammer symbol, defined by

[tex]\begin{cases}(0)_n = 1 \\ (a)_n = a(a+1)(a+2)\cdots(a+n-1) = \frac{\Gamma(a+n)}{\Gamma(a)}\end{cases}[/tex]

We'll be needing the following identities later.

[tex](1)_n = n! = \dfrac{\Gamma(n+1)}{\Gamma(1)}[/tex]

[tex](x)_n = \dfrac{\Gamma(n+x)}{\Gamma(x)}[/tex]

[tex](x+1)_n = \dfrac{\Gamma(n+x+1)}{\Gamma(x+1)}[/tex]

The [tex]m[/tex]-sum is

[tex]\displaystyle \sum_{m=1}^\infty \frac{\Gamma(m)}{\Gamma(n+m+x)} = \frac1{\Gamma(n+x)} \sum_{m=1}^\infty \frac{\Gamma(m)\Gamma(n+x)}{\Gamma(n+m+x)} \\\\ ~~~~~~~~ = \frac{S(n+x)}{\Gamma(n+x)} \\\\ ~~~~~~~~ = \frac{\Gamma(n+x-1)}{\Gamma(n+x)^2}[/tex]

Then the double sum reduces to

[tex]\displaystyle \sum_{n=1}^\infty \sum_{m=1}^\infty \frac{\Gamma(n)\Gamma(m)\Gamma(x)}{\Gamma(n+m+x)} = \sum_{n=1}^\infty \frac{\Gamma(n)\Gamma(x)\Gamma(n+x-1)}{\Gamma(n+x)^2}[/tex]

Rewrite the summand. We use the property [tex]\Gamma(x+1)=x\Gamma(x)[/tex] to convert to Pochhammer symbols.

[tex]\displaystyle \frac{\Gamma(n)\Gamma(x)\Gamma(n+x-1)}{\Gamma(n+x)^2} = \frac{\Gamma(n)\Gamma(x)^2\Gamma(n+x-1)}{\Gamma(n+x)^2 \Gamma(x)}[/tex]

[tex]\displaystyle . ~~~~~~~~ = \frac1{x^2} \frac{\Gamma(n)\Gamma(x+1)^2\Gamma(n+x-1)}{\Gamma(n+x)^2\Gamma(x)}[/tex]

[tex]\displaystyle . ~~~~~~~~ = \frac1{x^2} \frac{\Gamma(n) \frac{\Gamma(n+x)}{\Gamma(x)}}{\frac{\Gamma(n+x-1)^2}{\Gamma(x+1)^2}}[/tex]

[tex]\displaystyle . ~~~~~~~~ = \frac1{x^2} \frac{(n-1)! (x)_{n-1}}{\left[(1+x)_{n-1}\right]^2}[/tex]

Now in the sum, shift the index to start at 0, and introduce an additional factor of [tex]n![/tex] to get the hypergeometric form.
