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

7x+5=6x I don’t get this because I have no idea what to subtract by, and I know the answer is -5 but I have no idea how to get there
Answer:
Step-by-step explanation:
7x + 5 = 6x Subtract 6x from both sides
7x - 6x +5 = 6x -6x
x + 5 = 0 Subtract 5 to both sides
x + 5 - 5 = 0 - 5

Michael drives 50 miles per hour. Stephen drives 49 miles per hour. They started at the same spot, and drove
in opposite directions. After some time, they were 999.9 miles apart. How much time has passed?
Answer:
See below
Step-by-step explanation:
When you see PER think fractions. Miles PER hour is
[tex] \frac{miles}{hour} [/tex]
We are given miles and told to solve for time. Use your knowledge of fractions to get what you need
The reciprocal of mi/hr would get what we need
[tex]miles \times \frac{hours}{miles} [/tex]
Miles cancels out here. So that means you can do this
[tex] \frac{1hour}{50miles} \times 999.9 \: miles[/tex]

The position of the particle as a function of time is given by x(t) = e-(t - 3)2, where x is in meters and t is in seconds. What is the velocity of the particle, in meters per second, at t = 2.5 s?
The velocity of the particle, in meters per second is 0.78 m/s
How to determine the velocity of the particle, in meters per second?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

[tex] \displaystyle \rm \sum_{n = 1}^ \infty \sum_{m = 1}^{ \infty } \frac{ \Gamma(n) \Gamma(m) \Gamma(x)}{ \Gamma(n + m + x)} [/tex]
Recall the beta function definition and gamma identity,
[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]

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)

12x - 12y + 8z + 4x + 12y - 4z = 8
16x + 4z = 8
4x + z = 2 ...(5)
Now, subtracting equation 4 from 5, we get-

-2z = 4
z = 4/-2
z = -2
Thus, 4x - 2 = 2
4x = 4

A regular pentagon has a side length of 2x+9. A square has a side length of 3x
The possible solution for x can be 22.5.
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:

Step-by-step explanation:
The required probability that exactly 3 out of 8 workers drive to work alone is 0.0165.
What is probability?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.

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.
How to locate the point that partitions a line segment lying on a number line
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
