Answer:

proportional relationship does not exist.

proportional relationship does exist.

proportional relationship does not exist.

proportional relationship does exist.

Step-by-step explanation:

To establish proportionality :

For data 1:

y α x

y = kx ; k = proportionality constant

Take x = 1 ; y = 5

5 = k

k = 5

Hence, to obtain other data points :

y = 5x (if data is proportional ; if otherwise, the data isn't proportional).

Take ; x = 2

y = 5* 2 = 10

10 ≠ 9

Hence, data isn't proportional.

2.)

Data 2:

y α x

y = kx ; k = proportionality constant

Take x = hours 2 ; y = miles = 110

110 = 2k

k = 110/2

k = 55

Take ; x = 5

y = 55*5 = 275

275 = 275 (proportional relationship exist)

3.)

For the graph:

First graph isn't proportional

4 = 2k ; k = 4/2 = 2 ; k = 2

At x = 6

y = 6*2 = 12

From graph ; y = 8 at x = 6

Hence, proportional relationship does not exist.

4.)

For the 2nd graph:

4 = 2k ; k = 4/2 = 2 ; k = 2

At x = 6

y = 6*2 = 12

From graph ; y = 12 at x = 6

Hence, proportional relationship does exist.

Points A and B have the same x-coordinates but opposite y-coordinates. How many units away are each of the points from the y-axis?
3
4
6
7

Answers

Answer:

Each point is 4 units away from the y-axis.

Step-by-step explanation:

Coordinates of point (x, y) defines the distance of the point from y-axis and x-axis.

x-coordinate → distance from the y-axis

y-coordinate → distance from x-axis

Coordinates of A → (-4, 3)

Coordinates of B → (-4, -3)

So both the points have same x-coordinates but opposite y-coordinates.

Therefore, each point is 4 units away from the y-axis.

Element X is a radioactive isotope such that every 5 years, its mass decreases by half.
Given that the initial mass of a sample of Element X is 590 grams, how much of the
element would remain after 23 years, to the nearest whole number?

Answers

Answer: 24 grams of element would remain.

Step-by-step explanation:

Exponential function for decay:

[tex]f(x)=Ab^{\frac{x}{n}}[/tex] ....(i) , where A = initial value , b = decay factor, x = time , n= time per period

As per given,

A = 569 grams , [tex]b=\dfrac12[/tex]

n= 5 years, t = 23 years

Put all values in (i) , we get

[tex]f(23)=590(\dfrac12)^{\frac{23}{5}}\\\\\\=590\times 0.0412346222117\\\\=24.3284271049\approx 24[/tex]

Hence, after 23 years , 24 grams of element would remain.

From the graph, derive the best fit equation :

Using the points ;

(0,2.5)  (100 ,35)

x1 = 0 ; y1 = 2.5 ; x2 = 100 ; y2 = 35

Slope formula, m = (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = 0.325

The y intercept, value on the graph where best fit line crosses the y axis = 2.5

The equation :

y = mx + c

c = intercept ; m = slope

y = 0.325x + 2.5

y = Number of cars

x = number of customers

The number of customers if there are 10 cars parked :

10 = 0.325x + 2.5

10 - 2.5 = 0.325x

7.5 = 0.325x

x = 7.5 / 0.325

x = 23.076

x = 23

Jacob Bearint decides to pick one card at random from a standard deck of 52 cards. What is the probability that the card Jacob chooses is either a four or a six? P ( 4 ∪ 6 ) =

Answers

Answer:

2 / 13

Step-by-step explanation:

Number of cards in a standard deck = 52

Number of 4's = 4 ( 1 for each suit)

Number of 6's = 4 (1 for each suit)

Probability, P = required outcome / Total possible outcomes

P(a 4) = 4 / 52 = 1/ 13

P(a 6) = 4 /52 = 1/13

Probability of either a 4 or a 6

P(a 4) + P(a 6)

1/13 + 1/13

= 2 / 13

SHOW STEPS PLS

Answers

Answer:

[tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex]

Step-by-step explanation:

Given expression is,

f(x) = 8x³ - 6x² - 36x + 27

For zeros of the function,

f(x) = 0

8x³ - 6x² - 36x + 27 = 0

2x²(4x - 3) - 9(4x - 3) = 0

(2x² - 9)(4x - 3) = 0

(2x² - 9) = 0

x² = [tex]\frac{9}{2}[/tex]

x = [tex]\pm\frac{3}{\sqrt{2}}[/tex]

x = [tex]\pm \frac{3\sqrt{2}}{2}[/tex]

Or (4x - 3) = 0

x = [tex]\frac{3}{4}[/tex]

Therefore, all zeros of the given functions are  [tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex].
