Find the nth term of this number sequence
15, 12, 9, 6, ..

Answer:

Step-by-step explanation:

To be parallel the slopes must be equal

4x-3y=15

3y=4x-15

y=(4x-15)/3

so m=4/3

Only line D. has a slope of 4/3

Answer:

D. y = (⁴/₃)x – 1

Step-by-step explanation:

To find the answer to this problem, we need to find the slope of 4x – 3y = 15 . Why? A line that is parallel to another line has the same slope as the other line.

The question gives the line in standard form, but all the options are in slope-intercept form. In addition, standard form is the only type of linear equation that does not explicitly give the slope. The slope is the change in the dependent variable, y, over the change in the independent variable, x. This means we need to solve the equation for y and so:

4x – 3y = 15  — original equation

4x – 3y – 4x = 15 – 4x  — subtracting 4x on each side to isolate 3y and reverse the addition of 4x

–3y = 15 – 4x  — simplifying; the 4x on the left cancels out

–3y ÷ –3 = (15 – 4x) ÷ –3  — dividing both sides by –3 to isolate y

–3y ÷ –3 = (15 ÷ –3) + (–4x ÷ –3)  — distributing the division by –3 on the right side to make it easier to understand

y = (⁴/₃)x – 5  — simplifying; this is our expression for y, and it gives us the slope

Now, which line has a slope of ⁴/₃? That would be Option D, y = (⁴/₃)x – 1, so that's our answer.

Of course, you could have just found two points on the graph and then used point-slope form to solve for the slope, but that takes more time…

I hope this makes it easier to understand the concept! Have a great day!

The probability that the remaining bill is a $2 bill is approximately 0.2857 or 28.57%.

To solve this problem, we can use conditional probability. Let's denote the events as follows:

A: The wallet initially contains a $2 bill.

B: The wallet initially contains a $20 bill.

C: The bill drawn from the wallet is a $2 bill.

We want to find the probability of Provenience is the horizontal and vertical position of an artifact within the matrix.  A occurring given that event C has occurred, P(A|C).

To begin, let's analyze the given information:

- The wallet either contains a $2 bill or a $20 bill, with equal likelihood. So, P(A) = P(B) = 0.5.

- If the wallet initially contains a $2 bill (event A), the probability of drawing a $2 bill (event C) is 2/3, since there are two $2 bills and one $20 bill in the wallet.

- If the wallet initially contains a $20 bill (event B), the probability of drawing a $2 bill (event C) is 1/2, as there is only one $2 bill left in the wallet.

Now, let's calculate the probability using Bayes' theorem:

P(A|C) = (P(C|A) * P(A)) / P(C)

P(C|A) = 2/3 (probability of drawing a $2 bill given that the wallet initially contains a $2 bill)

P(C) = P(C|A) * P(A) + P(C|B) * P(B) (total probability of drawing a $2 bill)

P(C|B) = 1/2 (probability of drawing a $2 bill given that the wallet initially contains a $20 bill)

P(C) = (2/3 * 0.5) + (1/2 * 0.5) = 1/3 + 1/4 = 7/12

P(A|C) = (2/3 * 0.5) / (7/12)

      = 4/6 / 7/12

      = (4/6) * (12/7)

      = 2/7

Therefore, the chances that the remaining bill in the wallet is a $2 bill, given that a $2 bill was drawn, is 2/7 or approximately 0.2857 (or 28.57%).

So, the probability that the remaining bill is a $2 bill is approximately 0.2857 or 28.57%.

The correct answer is B) y - 20 = 12(x - 1). It matches the equation of the line Donovan drew, where the slope is 12 and the y-intercept is 20.

To determine the equation of the line Donovan drew, we need to find the slope and the y-intercept of the line.

Given information:

After 1 day, Donovan sold 20 copies (x = 1, y = 20).

After 2 days, Donovan sold 32 copies (x = 2, y = 32).

To find the slope of the line, we can use the formula:

slope (m) = (change in y) / (change in x).

Change in y = 32 - 20 = 12.

Change in x = 2 - 1 = 1.

Therefore, the slope (m) = 12/1 = 12.

Now, we can use the slope-intercept form of a linear equation (y = mx + b) to find the y-intercept (b).

Using the point (1, 20) on the line:

y = mx + b

20 = 12(1) + b

20 = 12 + b

b = 20 - 12

b = 8.

Therefore, the equation of the line Donovan drew is:

y = 12x + 8.

Comparing this equation to the answer choices:

A) Ay - 2 = 12(x - 1)

B) y - 20 = 12(x - 1)

C) y - 20 = 12(x - 2)

D) y - 32 = 12(x - 20)

We can see that the correct answer is B) y - 20 = 12(x - 1). It matches the equation of the line Donovan drew, where the slope is 12 and the y-intercept is 20.

False. In cubic closest packing (CCP) or face-centered cubic (FCC) structure, the unit cell is not body-centered cubic (BCC). The unit cell in CCP/FCC is composed of a cube with lattice points at the corners and an additional lattice point at the center of each face.

The term "cubic closest packing" refers to the arrangement of atoms or spheres in a cubic lattice where the spheres touch each other along their faces.

This arrangement is achieved by stacking layers of spheres in an ABCABC... pattern. Each sphere is in contact with 12 surrounding spheres, resulting in a coordination number of 12.

On the other hand, the body-centered cubic (BCC) structure has a different arrangement. In BCC, the unit cell consists of a cube with lattice points at the corners and an additional lattice point at the center of the cube. Each atom or sphere in BCC is in contact with eight neighboring atoms.

Therefore, the statement that the unit cell in cubic closest packing is body-centered cubic is false. The correct unit cell for cubic closest packing or face-centered cubic packing is the face-centered cubic (FCC) structure.

Answer:

The correct answer is: 2. t=0.45a

Step-by-step explanation:

Let t be the price of apples

and a be the number of apples

The price and quantity are directly proportional

\(t \propto a\)

Removing the proportionality symbol introduces a proportionality constant in the equation

\(t = ka\)

So far we know that cost of 6 apples is $2.70

Putting in the equation

\(2.70 = k (6)\\k = \frac{2.70}{6}\\k = 0.45\)

Putting the values of k will give us:

\(t = 0.45a\)

Hence,

The given equations of planes are: 15x - 3y + 12z = 2  & 2y = 10x - 8z

To determine whether these planes are parallel, perpendicular or neither, we need to compare the normal vectors of the planes. The normal vector of a plane is given by the coefficients of x, y and z in the equation of the plane.

The normal vector of the first plane (1) is [15, -3, 12] and the normal vector of the second plane (2) is [10, 2, -8/2] = [10, 2, -4].

Now, to check if the planes are parallel or perpendicular, we can take the dot product of the normal vectors. If the dot product is 0, then the planes are perpendicular, and if it is non-zero, then the planes are parallel.

The dot product of the normal vectors of the given planes is:

[15, -3, 12] · [10, 2, -4] = (15)(10) + (-3)(2) + (12)(-4) = 0

Since the dot product is zero, the planes are perpendicular to each other.

Answer:

Samir would need to invest about $6,644.96, rounded to the nearest ten dollars, for the value of the account to reach $14,000 in 16 years.

Step-by-step explanation:

We can use the formula for compound interest:

A = P(1 + r/n)^(n*t)

where:

A = final amount (in this case, $14,000)

P = initial principal (what Samir needs to invest)

r = interest rate (2.5% or 0.025)

n = number of times the interest is compounded per year (365, since it's compounded daily)

t = time (16 years)

Substituting these values into the formula, we get:

14000 = P(1 + 0.025/365)^(365*16)

Simplifying the right side, we get:

14000 = P(1.00006849315)^5840

Dividing both sides by (1.00006849315)^5840, we get:

P = 14000/(1.00006849315)^5840

Using a calculator, we get:

P ≈ 6,644.96

So Samir would need to invest about $6,644.96, rounded to the nearest ten dollars, for the value of the account to reach $14,000 in 16 years.

The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

The area of the shaded region between x=y^(2)-7 y=1 x=e^y y=-1 is e + 1/e + 12 square units.

To find the area shaded region, we need to first graph the curves and determine the boundaries of the region.

The given equations are:

x = y^2 - 7 (equation 1)

y = 1 (equation 2)

x = e^y (equation 3)

y = -1 (equation 4)

From equation 2, we know that the line y = 1 is a horizontal line passing through (0, 1).

From equation 4, we know that the line y = -1 is a horizontal line passing through (0, -1).

To graph equation 1, we can rewrite it as x + 7 = y^2 and complete the square:

x + 7 = (y - 0)^2 + 0

(y - 0)^2 = x + 7

This is the equation of a parabola with vertex at (-7, 0) and axis of symmetry parallel to the y-axis. Since the parabola opens to the right, we only need to graph the part of the parabola to the right of the vertex.

To graph equation 3, we note that e^y is always positive, so the curve will be to the right of the y-axis. Also, since e^y increases rapidly as y increases, the curve will approach the x-axis asymptotically.

The shaded region is bounded by the curves x = y^2 - 7, x = e^y, y = 1, and y = -1. We can find the boundaries of the region by finding the intersection points of the curves.

To find the intersection of equations 1 and 2, we substitute y = 1 into equation 1:

x = 1^2 - 7 = -6

So the point of intersection is (-6, 1).

To find the intersection of equations 1 and 4, we substitute y = -1 into equation 1:

x = (-1)^2 - 7 = -6

So the point of intersection is also (-6, -1).

To find the intersection of equations 2 and 3, we substitute y = 1 into equation 3:

x = e^1 = e

So the point of intersection is (e, 1).

Therefore, the boundaries of the shaded region are x = -6, x = e, and the curves y = 1 and y = -1.

We can now set up the integral to find the area of the shaded region:

A = ∫[-1,1] ∫[-6,e^y] dx dy

Integrating with respect to x first, we have:

A = ∫[-1,1] (e^y + 6) dy

Integrating with respect to y, we have:

A = [e^y + 6y]_[-1,1]

A = (e + 6) - (1/e + (-6))

A = e + 6 + 1/e + 6

A = e + 1/e + 12

Therefore, the area of the shaded region is e + 1/e + 12 square units.

Step-by-step explanation:

The company charges an initial fee of $45.00

The cost increases by $8.50 for each person who attends the event.

The correct options are B and C

As per the given data:

The equation y = 8.50x + 45.00 can be used to predict the cost of the meals if x people attend the event.

By comparing this equation with the slope intercept form y = mx + c

x = 0 {zero people}

y = 8.50(0) + 45.00

y = $45.00

For increase in cost with each person attending the event:

Cost for 2 persons - Cost for 1 person

= 8.50(2) + 45.00 - [8.50(1) + 45.00]

= 8.50(2) - 8.50(1)

= $8.50

This is the slope of the line
