which equation represents the tape diagram?

Answer: an=2(-2)ⁿ⁻¹    a₉=512     a₆=-64

Step-by-step explanation:

Since we have an alternating minus sign in this sequence, therefore the first multiplier of the following sequence will be (-1)ⁿ.

And since the first term of the following sequence is positive, the first multiplier of the following sequence is (-1)ⁿ⁻¹.

The second multiplier of the following sequence is 2ⁿ because the sequence has the form: 2, 4, 8, 16, ..., 2ⁿ .

[tex]Thus,\ a_n=(-1)^{n-1}(2^n)\\\\ a_n=2(-2)^{n-1}\ \ \ (1)[/tex]

Find the 9th and 6th terms of the sequence by formula (1):

a₉=2(-2)⁹⁻¹

а₉=2(-2)⁸

a₉=2(256)

a₉=512

a₆=2(-2)⁶⁻¹

а₆=2(-2)⁵

a₆=2(-32)

a₆=-64

What is Piecewise function?

A piecewise function is used to relate multiple functions at different intervals

The cost for 9 people

This means that:

n=9

When n = 9, the cost function is:

C(9)=150

Hence, it will cost #150 to have a party with 9 people

The cost for 20 people

This means that:

The weight of container will be 20 kg

Let x be the number of car toys packed into container. Toy cars weigh 3 kilogram apiece and are shipped in a container that weighs 5 kilograms when empty, then the total weight of container with toy cars is

x.3 + 5 = 3x + 5

The number of toy trucks is also x. Toy trucks, which weigh 2 kilograms apiece, are shipped in a container weighing 10 kilograms, then the total weight of container with toy trucks is

x.2 + 10 = 2x +10

When packed with toys and ready for shipment, both kinds of containers have the same weight. Thus,

3x + 5 = 2x + 10

x = 15

The weight of container = x + 5

= 15 + 5

= 20 kg

Hence, the weight of container will be 20 kg

The slope-intercept form of a straight line of equation 5x + 2y = 10 is y = (-5/2)x + 5.

The slope-intercept form of a line is:

y = mx + b

where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

To put the equation 5x + 2y = 10 in slope-intercept form, we need to solve for y. We can do this by rearranging the terms and isolating y:

2y = -5x + 10

y = (-5/2)x + (10/2)

Thus, the slope-intercept form of the equation 5x + 2y = 10 is:

y = (-5/2)x + 5

This means that the slope of the line is (-5/2) and the y-intercept is (0,5).

The end behavior of the graph of f(x) = x^5 + 8x^4 + 16x^3 is asymptotic: it goes towards positive infinity as x approaches positive infinity, and negative infinity as x approaches negative infinity.

The end behavior of the graph of a polynomial function with degree 5 is determined by the leading term, which in this case is x^5. Since the degree of the leading term is odd and the coefficient is positive, the graph of f(x) = x^5 + 8x^4 + 16x^3 will approach positive infinity as x approaches positive infinity, and negative infinity as x approaches negative infinity. This is known as an asymptotic end behavior. As the x-values get larger and larger, the magnitude of the y-values will also get larger and larger, approaching infinity in either direction. This can be seen by looking at the graph of the function, which will have an "S" shape that curves up and to the right (positive infinity) for large positive x-values, and down and to the left (negative infinity) for large negative x-values.

For x > 0, the end behavior is:

f(x) = x5 + 8x4 + 16x3

lim x→∞ f(x) = lim x→∞ x5 + 8x4 + 16x3

lim x→∞ f(x) = lim x→∞ x5

lim x→∞ f(x) = +∞

For x < 0, the end behavior is:

f(x) = x5 + 8x4 + 16x3

lim x→−∞ f(x) = lim x→−∞ x5 + 8x4 + 16x3

lim x→−∞ f(x) = lim x→−∞ x5

Answer:

Step-by-step explanation:

The y-intercept of g(x) is 3 * 2 = 6.

To find the x-intercepts of g(x), we need to find the values of x that make g(x) equal to 0. Since g(x) = 2f(2x + 3), this means we need to find the values of x that make f(2x + 3) equal to 0. Therefore, we can find the x-intercepts of g(x) by solving the equation f(2x + 3) = 0 for x.

Since the x-intercepts of f(x) are at 2 and -4, this means that the equation f(x) = 0 has solutions at x = 2 and x = -4. Substituting these values into the equation f(2x + 3) = 0, we get:

f(2(2) + 3) = 0

f(4 + 3) = 0

f(7) = 0

and

f(2(-4) + 3) = 0

f(-8 + 3) = 0

f(-5) = 0

Therefore, the x-intercepts of g(x) are at x = 7/2 and x = -5/2. These are the only intercepts of g(x) that we can determine for certain.

Step-by-step explanation:

Solving the inequality  [tex]\frac{2x + 4}{2}[/tex] < 6, we get x < 4.

Linear Inequalities are mathematical expressions which consist of a left hand side and a right hand side connected with inequality signs like <, >, ≤, ≥ and ≠.

They are almost like linear equations when we see it, but the '=' sign in linear equations are substituted with inequality signs like those mentioned earlier.

The expression given here is,

[tex]\frac{2x + 4}{2}[/tex] < 6

Multiplying both sides with 2, we get,

2x + 4 < 6 × 2

2x + 4 < 12

Subtracting both sides with 4, we get,

2x + 4 - 4 < 12 - 4

2x < 8

Dividing both sides by 2,

2x / 2 < 8 / 2

x < 4

Hence the inequality [tex]\frac{2x + 4}{2}[/tex] < 6 results in x < 4.

The absolute value of a number is the non-negative distance between the number and zero on a number line, regardless of sign.

This means that the absolute value of a negative number is always positive. Therefore, if a and b both are negative numbers, their absolute values will be positive numbers. If a is greater than b, then the absolute value of a must be greater than the absolute value of b. This can be expressed mathematically as follows:

|a| > |b|

This equation states that the absolute value of a is greater than the absolute value of b. In other words, the distance between a and zero is greater than the distance between b and zero on a number line.

To illustrate this, let’s take an example of two negative numbers, a=-3 and b=-5. The absolute values of these two numbers are 3 and 5 respectively. Since 3 is greater than 5, the absolute value of a is greater than the absolute value of b. This holds true regardless of the sign of the numbers, as long as a is greater than b.

The time t at which the population is 500 is 45 hours.

The equation gives the rate of change of the population at time t:

dP/dt = kP

where P is the population at time t and k is the constant of proportionality.

We can use this equation to find the value of k by substituting the known values of P and t at time t=24 hours:

dP/dt = kP

1000 = k*300

k = 1000/300

k = 10/3

Now that we know the value of k, we can use the equation to find the time t at which the population is 500:

dP/dt = kP

500 = (10/3)P

P = 500*3/10

P = 150

Since the population at time t=0 hours is 300, the population has decreased by 150 over the 24 hours, so t = -150/(-10/3) = 45 hours.

Therefore, the time t at which the population is 500 is 45 hours.

Since the population at time t=0 hours is 300, the population has decreased by 150 over the 24 hours, so t = -150/(-10/3) = 45 hours.

Find the factors of the constant term (15) that add up to the coefficient of the middle term (7). The factors of 15 are 1 and 15, 3 and 5, and 5 and 3. The only pair that adds up to 7 are 3 and 5.

Set the coefficients of the two binomials to 3 and 5, respectively. The expression becomes: [tex](2x^2 + 3x + 5)(5x + 3)[/tex]

Rewrite the binomials using the distributive property: [tex](2x^2 + 3x + 5)(5x + 3) = (2x^2 + 5x + 3x + 15) = 2x(x + 5) + 3(x + 5) = (2x + 3)(x + 5)[/tex]

A unique array value is a value that appears only once among all the other values in the given array. Hence the name unique.

An array is a set of items, images, or numbers arranged in rows and columns. Arrays are practical illustrations of multiplication ideas.

Arrays are needed in cases where you need  to store and manipulate large amounts of data efficiently.

Some of the benefits of using arrays include:

1. Arrays allow you to store a large number of items in a single data structure, which makes it easier to work with large datasets.

2. Arrays allow you to access and modify the items in the array quickly, using the index of the item.

A data structure called an array is used to hold a number of elements together. Each item in an array is recognized by its index, or place within the array. A value that only appears once in an array is considered to be unique array value. Think about the following array, for instance:

[1, 2, 3, 4, 5, 6]

Because each value only occurs once in this array, each value is distinct.

Contrarily, think about the following array:

Since it appears twice in this array, the number 3 is not unique. Since they only exist once, each of the other values is distinct.
