Step-by-step explanation:

The solution is, the nth term of the sequence is: an = 250 * 0.4(n-1)

To find a formula for the nth term of the sequence 250, 100, 40, we need to first determine the pattern or rule that generates the sequence. If we divide each term by the previous term, we get the following ratios:

100/250 = 0.4

40/100 = 0.4

We can see that each term is obtained by multiplying the previous term by the common ratio of 0.4.

So, the formula for the nth term of the sequence is:

an = a1* r(n-1)

where a1= 250 is the first term, r = 0.4 is the common ratio, and n is the term number.

The solution is, the nth term of the sequence is: an = 250 * 0.4(n-1)

A circle with Centre [tex](a,b)[/tex]  has the general equation:

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]

where [tex]r[/tex] is the radius and [tex](a,b)[/tex] is the Centre.

Given that the Centre is at [tex](0,9)[/tex], the equation is as follows:

[tex](x-0)^2 + (y-9)^2 = r^2[/tex]

If we simplify, we get:

[tex]x^2 + (y-9)^2 = r^2[/tex]

The fact that the circle comprises the coordinates  [tex](65,12)[/tex]  is also provided. Therefore, we may change these values into the equation and find [tex]r[/tex]:

[tex]65^2 + (12-9)^2 = r^2[/tex]

[tex]4225 + 9 = r^2[/tex]

[tex]r^2 = 4234[/tex]

When we square the two sides, we obtain:

The factorization of p(x) is p(x) = (x + 5)^2 (x - 3).

There are different methods to find the zeros of a polynomial, but one common approach is to use the Rational Root Theorem to test possible rational roots and then use polynomial division to factor out the roots found.

The Rational Root Theorem states that if a polynomial with integer coefficients has a rational root p/q (where p and q are integers with no common factors other than 1), then p must divide the constant term and q must divide the leading coefficient.

In the case of p(x) = x³ + x² + 8x - 60, the constant term is -60 and the leading coefficient is 1, so the possible rational roots are of the form p/q, where p is a factor of -60 and q is a factor of 1. Therefore, the possible rational roots are ±1, ±2, ±3, ±4, ±5, ±6, ±10, ±12, ±15, ±20, ±30, ±60.

Since the remainder is not zero, x = 1 is not a root of p(x). We can repeat this process with each possible root until we find all the actual roots.

Using this method, we find that the zeros of p(x) are:

x = -5 (with multiplicity 2) and x = 3.

Therefore, the factorization of p(x) is:

p(x) = (x + 5)² (x - 3)

Answer:

The correct answer is (D) 4/5.

Step-by-step explanation:

First, we need to find the number of cars that are neither red nor have a backup camera.

Number of cars that are not red = 50 - 12 = 38

Number of cars that do not have a backup camera = 50 - 10 = 40

Number of cars that are neither red nor have a backup camera = 38 + 10 - 50 = 8

Therefore, the probability of selecting a car that is not red and does not have a backup camera is:

P(not red and no backup camera) = 8/50

Simplifying:

P(not red and no backup camera) = 4/25

So the correct answer is (D) 4/5.

A. Since the remainder is zero, (x+2) is indeed a factor of f(x).

B. So, f(x) is completely factored as (x+2)(x-1)(x-3).

C. The zeros of F(x) are: -2, 1, and 3.

To determine if (x+2) is a factor of f(x) = x³-3x²-7x+6 can use synthetic division or long division.

Using synthetic division:

-2 | 1  -3  -7  6

   -2   10  -6

    1  -5   3  0

Using the result from part A we can write:

f(x) = (x+2)(x²-5x+3)

The quadratic factor can be factored further using the quadratic formula or factoring by grouping:

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

So, f(x) is completely factored as (x+2)(x-1)(x-3).

The zeros of f(x) are the values of x that make f(x) equal to zero.

From the factored form of f(x) we can see that the zeros are -2, 1 and 3. So:

After 4 years of saving $315 per month at 7% annual interest rate, Bernard will have saved approximately $10,864.11.

To calculate the amount that Bernard will have saved after 4 years, we can use the formula for compound interest:

A = P(1 + r/n[tex])^{(nt)[/tex]

Where:

A = the amount of money Bernard will have saved after 4 years

P = the amount of money Bernard is putting into savings each month = $315

r = the annual interest rate = 7% = 0.07

n = the number of times interest is compounded per year (monthly compounding in this case) = 12

t = the number of years = 4

Substituting the given values into the formula, we get:

A = 315(1 + 0.07/12[tex])^{(12\times 4)[/tex]

A = 315(1.00583333[tex])^{48[/tex]

A = 315(1.31564)

Answer:

The option that the margin of error accounts for in the given interval is sampling variation.

Step-by-step explanation:

Answer:

To calculate the distance around the outside of the circular fire pit (circumference), we can use the formula:

Circumference = π × diameter

Given that the diameter of the pit is 3 feet, we can substitute this value into the formula:

Circumference = π × 3 feet

For the exact distance, we can use the value of π (pi) as 3.14159 (approximately):

Circumference ≈ 3.14159 × 3 feet

Circumference ≈ 9.42477 feet

For the approximate distance, we can round π to 3:

Circumference ≈ 3 × 3 feet

Circumference ≈ 9 feet

To calculate the area inside the circular fire pit, we can use the formula:

Area = π × (radius)^2

The radius is half of the diameter, so in this case, the radius is 1.5 feet.

For the exact area, using π as 3.14159:

Area ≈ 3.14159 × (1.5 feet)^2

Area ≈ 7.06858 square feet

For the approximate area, rounding π to 3:

Area ≈ 3 × (1.5 feet)^2

Area ≈ 6.75 square feet

Therefore, the homeowner would need to buy approximately 9 bricks to outline the pit, and approximately 7.07 square feet of sand to cover the space inside the pit (or approximately 6.75 square feet if rounding to a whole number).

The line with the equation y = -x - 2 will pass through the points (0, -2) and (2, -4) and continue infinitely in both directions.

We have,

To graph the line with the equation y = -x - 2, we can follow these steps:

- Step 1:

Plot two points on the graph.

Select any x-value and substitute it into the equation to find the corresponding y-value.

Repeat this process for a different x-value to find another y-value.

Let's choose x = 0:

y = -(0) - 2

y = -2

So we have the point (0, -2).

Let's choose x = 2:

y = -(2) - 2

y = -4

So we have the point (2, -4).

- Step 2:

Plot the points on a coordinate plane.

Plot the points (0, -2) and (2, -4) on a graph.

Step 3: Draw a line passing through the two plotted points.

Using a straightedge or by hand, draw a line that connects the two points.
