The greater unit rate of the two functions is . The greater y intercept of the two functions is

Step-by-step explanation:

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

(x₁, y₁) - point on a line

We have the point (3, -3) and the slope m = -2. Substitute:

[tex]y-(-3)=-2(x-3)[/tex]

[tex]y+3=-2(x-3)[/tex] - point-slope form

Convert to the slope-intercept form (y = mx + b):

[tex]y+3=-2(x-3)[/tex]        use the distributtive property

[tex]y+3=-2x+(-2)(-3)[/tex]

[tex]y+3=-2x+6[/tex]      subtract 3 from both sides

[tex]y=-2x+3[/tex] - slope-intercept form

Convert to the standard form (Ax + By = C):

[tex]y=-2x+3[/tex]        add 2x to both sides

[tex]2x+y=3[/tex] - standard form

Convert to the general form (Ax + By + C = 0):

[tex]2x+y=3[/tex]      subtract 3 from both sides

[tex]2x+y-3=0[/tex] - general form

For this case we must simplify the following expression:

[tex](4a^{ - 6} * b ^ 2)^{ - 3}[/tex]

By definition of power properties we have:[tex]a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

Then, rewriting the expression:

[tex](\frac {4} {a ^ 6} * b ^ 2) ^ {- 3} =\\\frac {1} {(\frac {4} {a ^ 6} * b ^ 2)^3} =\\\frac {1} {(\frac {4b ^ 2} {a ^ 6})^3} =[/tex]

By definition we have to:

[tex](a ^ n) ^ m = a ^ {n * m}[/tex]

[tex]\frac {1} {\frac {64b ^ 6} {a^{18}}}\\\frac {a^{18}} {64b ^ 6}[/tex]

Answer:

[tex]\frac {a^{18}} {64b ^ 6}[/tex]

Step-by-step explanation:

The x-intercepts are x = -1 and x = 5, so:

y = k (x + 1) (x − 5)

The vertex is (2, -3), so:

-3 = k (2 + 1) (2 − 5)

-3 = -9k

k = 1/3

y = 1/3 (x + 1) (x − 5)

Simplifying:

y = 1/3 (x² − 4x − 5)

y = 1/3 x² − 4/3 x − 5/3

f(x) =  1 / 3 x² - 4 / 3 x - 5 / 3

using the form:

f(x) = a(x - h)² + k

The vertex coordinates are 2 and -3.

h = 2

k = - 3

therefore,

f(x) = a(x - 2)²  - 3

f(x) = a(x - 2)² - 3

let's use the coordinates (-1, 0) to find a. Therefore,

0 = a(-1 - 2)² - 3

0 = 9a - 3

3 = 9a

a = 3 / 9

a = 1 / 3

let's insert the value of a in the equation.

f(x) = a(x - 2)² - 3

f(x) = 1 / 3 ( x - 2)² - 3

f(x) = 1 / 3 (x - 2)(x -2) - 3

f(x) = 1 / 3 (x² - 4x + 4) - 3

f(x) = x² / 3 - 4x / 3 + 4 / 3 - 3

f(x) =  1 / 3 x² - 4 / 3 x - 5 / 3

Answer:

1) yes

2) Option B

3) 9200

Step-by-step explanation:

1) yes

The exponential function is: y=-(x)^3

Putting the values of x in the given function we get the values of y.

x =1 , y= -(1)^3, y=-1

x= 2, y= -(2)^3, y = -8

x= 3, y= -(3)^3,y = -27

x= 4, y= -(4)^3,y = -64

2) f(x) = 160.2^x

if value of x = 2

then f(2) = 160.2^(2)

f(2) = 160.4

f(2) = 640

So, Option B is correct.

3) f(x) = 2300.2^x

if value of x = 2 decades then

f(2) = 2300.2^2

f(2) = 2300.4

f(2) = 9200

Since all options are not visible, so correct answer is 9200

Answer: the length is 13

Step-by-step explanation:

one side is 26 ft. and y is half of one side so by dividing 26 by 2 you would get 13

To solve this you must use Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 48

b = x

c = 50

^^^Plug these numbers into the theorem

[tex]48^{2} +x^{2} =50^{2}[/tex]

simplify

2304 + [tex]x^{2}[/tex] = 2500

Isolate x^2 by subtracting 2304 to both sides

[tex]x^{2}[/tex] = 196

To remove the square from x take the square root of both sides to get you...

To make a 20 pound blend of coffee that costs $9.50 per pound using Kenyan French Roast coffee ($10 per pound) and Sumatran coffee ($9 per pound), you should use 10 pounds of each type.

To solve this problem, we can set up a system of equations to represent the given information. Let x represent the amount of Kenyan French Roast coffee and y represent the amount of Sumatran coffee. We have the following equations:

x + y = 20 (equation 1 - representing the total weight of the blend)

10x + 9y = 9.50 * 20 (equation 2 - representing the total cost of the blend)

To solve this system, we can first multiply equation 1 by 10 to get:

10x + 10y = 200 (equation 3)

We can then subtract equation 3 from equation 2 to eliminate the variable x:

10x + 9y - (10x + 10y) = 9.50 * 20 - 200

9y - 10y = 190 - 200

-y = -10

y = 10

Substituting this value back into equation 1 gives us:

x + 10 = 20

x = 10

Therefore, we should use 10 pounds of Kenyan French Roast coffee and 10 pounds of Sumatran coffee to make the 20 pound blend.

Final answer:

The sequence 13, 29, 427, 881 is not geometric because each term is not obtained by multiplying the previous term by a constant ratio. The ratios between successive terms vary, so there is no common ratio.

Explanation:

Is the sequence 13, 29, 427, 881 geometric? To determine if a sequence is geometric, each term should be obtained by multiplying the previous term by a constant number, known as the common ratio.

Let's calculate the ratios between successive terms:

Since the ratios are not the same, the sequence is not geometric. Therefore, there is no common ratio.

[tex]w=\dfrac{1+i+i}{i(1+i)+2}\\\\w=\dfrac{1+2i}{i-1+2}\\\\w=\dfrac{1+2i}{1+i}\\\\w=\dfrac{(1+2i)(1-i)}{1+1}\\\\w=\dfrac{1-i+2i+2}{2}\\\\w=\dfrac{3+i}{2}\\\\w=\dfrac{3}{2}+\dfrac{1}{2}i[/tex]

To find the value of w, substitute the given value of z into the equation for w. Simplify the expression to obtain the value of w in the form x + iy, where x and y are real numbers.

To find the value of w, we first substitute the given value of z into the equation for w.

Given z = 1 + i, we have:

w = (1 + i + i) / (i(1 + i) + 2)

Simplifying the numerator:

w = (1 + 2i) / (i + i^2 + 2)

Since i^2 = -1, we can rewrite the equation as:

w = (1 + 2i) / (-1 + i + 2)

Simplifying further:

w = (1 + 2i) / (1 + i)

To divide complex numbers, we multiply the numerator and denominator by the conjugate of the denominator.

w = ((1 + 2i)(1 - i)) / ((1 + i)(1 - i))

w = (1 - i + 2i - 2i^2) / (1 - i^2)

Using i^2 = -1 again:

w = (1 + i + 2i + 2) / (1 - (-1))

Simplifying the numerator:

w = (3 + 3i) / 2

Dividing both terms by 2:

w = 3/2 + 3/2i

Therefore, w = 3/2 + 3/2i in the form x + iy, where x = 3/2 and y = 3/2 are real numbers.

namely, what is the leftover amount when the decay rate is 2% for an original amount of 75 grams after 10 years?

[tex]\bf \qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &75\\ r=rate\to 2\%\to \frac{2}{100}\dotfill &0.02\\ t=\textit{elapsed time}\dotfill &10\\ \end{cases} \\\\\\ A=75(1-0.02)^{10}\implies A=75(0.98)^{10}\implies A\approx 61.28\implies \stackrel{\textit{rounded up}}{A=61~grams}[/tex]

Answer with explanation:

The exponential decay function is written as :-

[tex]f(x)=A(1-r)^x[/tex], where f (x) is the amount of material left after x years , A is the initial amount of material and r is the rate of decay.

Given : The amount of original item remained now = 75 grams

The rate of decay = 2% = 0.02

Now, the amount of original artifact would there be left if they had not discovered it for another 10 years is given by :-

[tex]f(10)=75(1-0.02)^{10}[/tex]

Solving the above exponential equation , we get

Hence only 61 grams original artifact would there be left if they had not discovered it for another 10 years .

Answer:

f(x) = (x+2)(x+3)(x-(3-6i))(x-(3+6i))

f(x) = 270 + 189 x + 21 x^2 - x^3 + x^4

Step-by-step explanation:

First of all, we must know that complex roots come in conjugate pairs.

So the zeros of your equation would be

x = -2

x = -3

x = 3 - 6i

x = 3 + 6i

Your polynomial is of fourth degree.

f(x) = (x-(-2))(x-(-3))(x-(3-6i))(x-(3+6i))

f(x) = (x+2)(x+3)(x-(3-6i))(x-(3+6i))

Please , see attached image below for full expression

f(x) = 270 + 189 x + 21 x^2 - x^3 + x^4

Answer:

The required polynomial is [tex]P(x)=a\left(x^4-x^3+21x^2+189x+270\right)[/tex].

Step-by-step explanation:

The general form of a polynomial is

[tex]P(x)=a(x-c_1)^{m_1}(x-c_2)^{m_2}...(x-c_n)^{m_n}[/tex]

where, a is a constant, [tex]c_1,c_2,..c_n[/tex] are zeroes with multiplicity [tex]m_1,m_2,..m_n[/tex] respectively.

It is given that  –2, –3,3 – 6i are three zeroes of a polynomial.

According to complex conjugate root theorem, if a+ib is a zero of a polynomial, then a-ib is also the zero of that polynomial.

3 – 6i is a zero. By using complex conjugate root theorem 3+6i is also a zero.

The required polynomial is

[tex]P(x)=a(x-(-2))(x-(-3))(x-(3-6i))(x-(3+6i))[/tex]

[tex]P(x)=a(x+2)(x+3)(x-3+6i)(x-3-6i)[/tex]

[tex]P(x)=a\left(x^2+5x+6\right)\left(x-3+6i\right)\left(x-3-6i\right)[/tex]

On further simplification, we get

[tex]P(x)=a\left(x^3+6ix^2+2x^2+30ix-9x+36i-18\right)\left(x-3-6i\right)[/tex]

[tex]P(x)=a\left(x^4-x^3+21x^2+189x+270\right)[/tex]

Therefore the required polynomial is [tex]P(x)=a\left(x^4-x^3+21x^2+189x+270\right)[/tex].

To find the probability that Jenny will be called on twice, we multiply the probabilities of picking her on the first and second calls, which is 1/992.

To find the probability that Jenny will be called on twice, we need to consider the total number of possible outcomes and the number of favorable outcomes.

There are 32 students in Jenny's class, so the total number of possible outcomes is 32.

For the first call, the probability of picking Jenny is 1/32. After the first call, there are now 31 students left, with 1 of them being Jenny. So, the probability of picking Jenny again on the second call is 1/31.

To find the probability of both events happening, we multiply the probabilities together: (1/32) x (1/31) = 1/992.

The probability that Jenny will be called on twice is 1/992.

The probability that Jenny will be called twice in a class of 32 students is 0.00098. This rounds to 0.00 when rounded to the nearest hundredth.

To determine the probability that Jenny is called on twice when there are 32 students in the class, we start by finding the probability for one instance and then consider the repeated scenario.

To find the combined probability of both events happening (Jenny being called twice), we multiply the probabilities of each individual event:

(1/32) * (1/32) = 1/1024

Thus, the probability that Jenny will be called on twice is approximately 0.00098 when rounded to the nearest hundredth.

Answer:

9* 3 ^ (x-2)

Step-by-step explanation:

g(x) = 3^x

We know a^ (b) * a^(c) = a^ (b+c)

 9* 3 ^ (x+2) = 3^2 * 3 ^(x+2) = 3^(2+x+2) = 3^x+4  not equal to 3^x

3*(9^(x+2)) = 3*3^2(x+2) = 3^1 * 3^(2x+4) =3^(2x+4+1) = 3^(2x+5) not equal  

9* 3 ^ (x-2) = 3^2 * 3 ^(x-2) = 3^(2+x-2) = 3^x  equal to 3^x    

3*(9^(x-2)) = 3*3^2(x-2) = 3^1 * 3^(2x-4) =3^(2x-4+1) = 3^(2x-3) not equal        

Answer:

The midpoint of the line segment is (9,3).

Step-by-step explanation:

To find the midpoint of a line segment, we use the midpoint formula, ( (x1 + x2)/2, (y1+y2)/2).  This means that to find the midpoint, we must add together both of the x-values of the endpoints and divide by 2 and do the same with the y values, basically finding the average of the two endpoints, or the middle.

x1 + x2 = 10 + 8 = 18

18/2 = 9

y1 + y2 = 2 + 4 = 6

6/2 = 3

Therefore, the midpoint of the line segment is (9,3).

We have two parallel lines. The intersection point does not exist.

Therefore, this system of equations has no solution.

I guess one more does not hurt.

Notice that choice D is equivalent to the given equation y = -4x - 12.

The only equation that does not cross the given equation is y = -4x.

They have THE SAME SLOPE. This means they are parallel and thus lead to NO SOLUTION.

ANSWER: y = -4x

Answer:

[tex]y=-4x[/tex]

Step-by-step explanation:

A Linear System with no solution, therefore inconsistent, is graphically represented by a pair of parallel lines.

According to Analytic Geometry, a parallel line shares the same slope.

Given the options, the only parallel line to [tex]y=-4x-12[/tex] is [tex]y=-4x[/tex] Since [tex]y=-4(x+3)[/tex] despite having the same slope, is actually the same line [tex]y=-4x+12[/tex]

So [tex]y=-4x[/tex] will form a system that has no solution.

Answer:

The solution set is the interval (-∞ , 6] OR {x : x ≤ 6}

Step-by-step explanation:

* Lets explain how to find the solution set of the inequality

- The inequality is 5x - 9 ≤ 21

∵ 5x - 9 ≤ 21

- At first add 9 to both sides of the inequality to separate x in one

 side and the numbers in the other sides

∴ 5x - 9 + 9 ≤ 21 + 9

∴ 5x ≤ 30

- Lets divide both sides of the inequality by 5 to find the values of x

∴ (5x ÷ 5) ≤ (30 ÷ 5)

∴ x ≤ 6

- The solutions of the inequality is all real numbers smaller than

  or equal to 6

∴ The solution set is the interval (-∞ , 6] OR {x : x ≤ 6}

- We can represent this inequality graphically to more understand

 for the solution

- From the graph the solution set is the purple area

Answer:

the correct answer is D. Funtion 1 and 3 have the same rate of change but funtion 1 has greater y intercept

Step-by-step explanation:

If we organize the funtion 1, we have y= 2x+8

Funtion 2 the need to calculate the slope m = (y2-y1)/(x2-x1) the point on the y represent (y2,x2) and is (4,0) the point onn the x axis is (x1,y1) and is (-2,0)

So, m=(4-0)/(0-(-2) => m=(4/2) => m=2

Then, y=m(X-Xo) + Yo  . From the plot, I choose (x2,y2) as (Xo,Yo) So, (0,4)

y=2(X-0) +4 then y= 2x+4

From 3 equation the choose the value x=o and g(x)= 5 and x=1 and g(x)=7 and following the same m=(7-5)/(1-0) the slope is m=2. Following the same procedure before I choose x=0 and y=5

Then the equation is: y=2(x-0) + 5

So, opcion D is true

Answer:

Second table.

Step-by-step explanation:

A function has an additive rate of change if there is a constant difference between any two consecutive input and output values.

The additive rate of change is determined using the slope formula,

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

From the first table we can observe a constant difference of -6 among the y-values and a constant difference of 2 among the x-values.

[tex]m = \frac{ - 9- - 3}{4-2} = - 3[/tex]

For the second table there is a constant difference of 3 among the y-values and a constant difference of 1 among the x-values.

The additive rate of change of this table is

[tex]m = \frac{ - 1 - - 4}{3 - 1} = 3[/tex]

Therefore the second table has an additive rate of change of 3.

Step-by-step explanation:

The total volume is the volume of the rectangular prism at the bottom plus the volume of the pyramid on top.

The volume of the prism is width times length times height.

V = wlh

V = (3)(7)(4)

V = 84

The volume of the pyramid is one third the area of the base times the height.

V = ⅓ Ah

The base of the pyramid is a rectangle.  Its area is the width times length.  The height of the pyramid is the total height minus the height of the prism.

V = ⅓ (3)(7)(12−4)

V = 56

So the total volume is:

V = 84 + 56

V = 140

y=800 km

Step-by-step explanation:

Let the distance traveled by train be y and by bus be x.

Bus -x

Train -y

y=x+150 (since they traveled by train for a distance of 150 km more than by bus.)

The sum of the two is equal to 1450

x+y=1450

The two equations form simultaneous  equations which when solved simultaneously give the values of x and y.

y+x=1450

y-x=150

Adding the two we get:

2y=1600

Divide both sides by two:

y=800 km

Y is the distance traveled by train= 800 km
