Answer:

3 = 0.25 + 0.5d

Step-by-step explanation:

Given that:

Amount charged per hour = $2

Time left before inserting $d = 15 minutes

Total time after inserting $d = 3 hours

Total time of 3 hours = time left by previous driver + hours purchased with $d

$2 = 1 hour

$d = x

2x = d

x = d/2 ; 0.5d

Since 15 minutes is left before inserting $d

15 minutes to hour ; 15/60 = 0.25

Total time of 3 hours = time left by previous driver + hours purchased with $

3 = 0.25 + 0.5d

We have to find the area under the graph but since we are not given the graph ,So let's learn how it is done. To estimate the area under the graph of function f from x, you can use rectangles. Here's how you can do it:

Step 1: Divide the interval [a, b] into six equal subintervals.
Step 2: Calculate the width of each rectangle by dividing the total width of the interval [a, b] by the number of rectangles (in this case, 6).
Step 3: For each subinterval, find the value of the function f at the right endpoint of the subinterval.
Step 4: Multiply the width of the rectangle by the value of the function at the right endpoint to find the area of each rectangle.
Step 5: Add up the areas of all six rectangles to estimate the total area under the graph of f from x.

The graph of the line represents the total cost for a month as a function of the number of visits made.

To graph the function y = 20 + 2x, we can plot several points and then connect them with a straight line. Here are a few points we can use:

When x = 0 (no visits), y = 20

When x = 1 (one visit), y = 22

When x = 2 (two visits), y = 24

When x = 3 (three visits), y = 26

We can plot these points on a coordinate plane with x on the horizontal axis and y on the vertical axis. After this, we can then connect the dots with a straight line. This line represents the total cost for a month as a function of the number of visits made.

The probability of selecting all three purple balls is 0.1429 or approximately 14.29%.

To find the probability that all three balls are purple, we need to use the formula for the probability of the intersection of three events:

P(A and B and C) = P(A) x P(B|A) x P(C|A and B)

where A, B, and C are the events of drawing a purple ball from the bag on the first, second, and third draws, respectively.

The probability of drawing a purple ball on the first draw is:

P(A) = number of purple balls / total number of balls = 9 / 15

After drawing a purple ball on the first draw, there are now 8 purple balls left in the bag out of a total of 14 balls, so the probability of drawing a purple ball on the second draw, given that a purple ball was drawn on the first draw, is:

P(B|A) = number of purple balls left / total number of balls left = 8 / 14

After drawing two purple balls, there are now 7 purple balls left in the bag out of a total of 13 balls, so the probability of drawing a purple ball on the third draw, given that two purple balls were drawn on the first two draws, is:

P(C|A and B) = number of purple balls left / total number of balls left = 7 / 13

Therefore, the probability of drawing three purple balls in a row is:

P(A and B and C) = P(A) x P(B|A) x P(C|A and B) = (9 / 15) x (8 / 14) x (7 / 13) = 0.1429 or approximately 14.29%

So, the probability of selecting all three purple balls is 0.1429 or approximately 14.29%.

Answer:

y = 3/5x - 5

Step-by-step explanation:

y intercept is -5

slope is rise / run = 3/5

Answer:

y = - 3x² + 6x + 9

Step-by-step explanation:

given the zeros of a parabola x = a , x = b , then the factors are

(x - a) , (x - b)

here the zeros are x = - 1 and x = 3 , then

factors are (x + 1) and (x - 3)

the equation of the parabola is then the product of the factors, that is

y = a(x + 1)(x - 3) ← a is a multiplier

to find a substitute the point (0, 9 ) into the equation

9 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )

- 3 = a

then equation is

y = - 3(x + 1)(x - 3) ← expand factors using FOIL

  = - 3(x² - 2x - 3) ← distribute parenthesis by - 3

y = - 3x² + 6x + 9

Explanation:

The given function is

f(x) = x^2 - 2x - 3

The first step is to graph the function. We would substitute values of x into the function and find corresponding values of y or f(x). We have

For x = - 1, y = (- 1)^2 - 2(- 1) - 3 = 1 + 2 - 3 = 0

For x = 0, y = (0)^2 - 2(0) - 3 = 0 + 0 - 3 = - 3

For x = 1, y = (1)^2 - 2(1) - 3 = 1 - 2 - 3 = - 4

The linear function for this problem is defined as follows:

y = x + 50.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b

In which:

The graph touches the y-axis at y = 50, hence the intercept b is given as follows:

b = 50.

When x increases by 10, y also increases by 10, hence the slope m is given as follows:

m = 10/10

m = 1.

Hence the function is given as follows:

y = x + 50.

Answer:

\(a_{14} = 10496\)

Step-by-step explanation:

A geometric sequence is of the form:

\(ar^0, ar^1, ar^2, ar^3, \cdot \cdot \cdot\)

So the given values can be represent as:

\(1. \quad ar^5 = \frac{41}{256}\\2. \quad ar^{10} = -164\)

So you have a system of equations with two unknows \(a\) and \(r\). Then you can find one unknow in terms of the other.

\(a = \frac{-164}{r^{10}}\)

Now replace \(a\) in the first equation

\(\frac{-164}{r^{10}}r^5 = \frac{41}{256}\\\frac{-164}{r^{5}} = \frac{41}{256}\\r^5 = \frac{256 \cdot -164}{41} = -\frac{41984}{41}\\r = \sqrt[5]{-\frac{41984}{41}}\\\)

You don't have to worry about the negative number inside the root, because is a odd root then you can find odd negative numbers that give me the desire result.

\(r = -\frac{4\sqrt[5]{41} }{\sqrt[5]{41}} \\r = -4\)

For find \(a\) only replace \(r\) in whatever of the two equations.

\(-a4^5 = \frac{41}{256}\\-a1024 = \frac{41}{256}\\a = -\frac{41}{262144}\)

After find \(a\) and \(r\) use the next formula for find the \(14^{th}\) term.

\(ar^{13} = x\\-\frac{41}{262144} \cdot -4^{13} = x\\\\10496 = x\)
