If a_1 = 3 and a_n = 2a_n-1 the value of a_6 is 96.

To find the value of a_6, we can use the given recursive formula a_n = 2a_n-1. We know that a_1 = 3, and we can apply the formula repeatedly to find the subsequent terms:

The second term is:

a_2 = 2a_1 = 2(3) = 6

The third term is:

a_3 = 2a_2 = 2(6) = 12

The fourth term is:

a_4 = 2a_3 = 2(12) = 24

The fifth term is:

a_5 = 2a_4 = 2(24) = 48

The six term is:

a_6 = 2a_5 = 2(48) = 96

Hence, based on the provided information, the value of a_6 is 96.

Answer:

y=-2x-3.

Step-by-step explanation:

y=mx+b

First, find the slope:

points: (0,-3)(1,-5)

RISE OVER RUN: y2-y1 divided by x2-x1 = slope

-5--3=-2

1-0= 1

-2/1 = -2

SLOPE = -2

For the y-intercept (b) we look at where x=0, whatever value y is when x=0, is our y-intercept. In this case, our y-intercept is -3.

Therefore, y=-2x-3

Step-by-step explanation:

To check this answer, you could obviously graph the points, but without graphing, you can tell the line would be straight because each x value is multiplied by the same number to get the corresponding y value.

3 x 5 = 15, 4 x 5 = 20, etc. This shows linear growth. If each x value were multiplied by twice itself (3 x 6, 4 x 8, and so on), you wouldn't have a straight line because the number that x is multiplied by changes depending on the value of x.

Answer:

Below in bold.

Step-by-step explanation:

Vertex form.

y = a(x - h)^2 + k

The point (h, k) is the vertex so from the graph:

y = a(x - 1)^2 - 8

From the x -interesect we see that x = 6 when y = 0 so

0 = a(6 - 1)^2 - 8

25a - 8 = 0

a = 8/25

So the vertex form is

y = (8/25)(x - 1)^2 - 8.

Factored form:

y = (8/25)(x + 4)(x - 6)  

- as -4 and 6 are the zeros of the equation.

Standard form:

From the factored form we have

y = (8/25)(x^2 - 2x - 24)

y = 8/25 x^2 - 16/25 x - 192/25

or (in decimal form):

y = 0.32x^2 - 0.64x - 7.68.

Circle: Graph upwards/down wards

The given equation is in the form of a quadratic function y = ax^2 + bx + c, where a = -1/2, b = 0, and c = 8. This is a downward-opening parabola since the coefficient of x^2 is negative.

the graph of the function is shaped like a "U" and opens downwards.

Vertical Axis of Symmetry

The vertical axis of symmetry is given by the equation x = -b/2a. Here, b = 0 and a = -1/2. Therefore, the axis of symmetry is x = 0.

Vertex (plug in axis of symmetry)

To find the vertex of the parabola, we need to plug in the value of the axis of symmetry into the equation for x and solve for y. Since the axis of symmetry is x = 0, we have:

x = 0

y = -1/2x^2 + 8

y = -1/2(0)^2 + 8

y = 8

Therefore, the vertex of the parabola is (0, 8).

Y-intercept (plug in 0)

To find the y-intercept, we need to plug in x = 0 into the equation and solve for y. Therefore, we have:

x = 0

y = -1/2x^2 + 8

y = -1/2(0)^2 + 8

y = 8

Therefore, the y-intercept is (0, 8).

X-intercepts (Solve by Square Rooting)

To find the x-intercepts, we need to set y = 0 in the equation and solve for x. Therefore, we have:

0 = -1/2x^2 + 8

1/2x^2 = 8

x^2 = 16

x = ±4

Therefore, the x-intercepts are (-4, 0) and (4, 0).

Graph the equation below:

The graph of the equation y = -1/2x^2 + 8 is a downward-opening parabola with vertex at (0, 8) and x-intercepts at (-4, 0) and (4, 0). The y-intercept is (0, 8). The vertical axis of symmetry is x = 0. The graph would look like:

          8 |

            |    

            |        

            |    /\    

            |   /  \  

            |  /    \  

            | /      \

       ---- + ------- + ----

          -4      0      4

Note that the points (0, 8), (-4, 0), and (4, 0) are on the graph, and the axis of symmetry is a vertical line passing through the vertex.

The rate of memorization of a subject with forgetfulness taken into account can be described as a declining function over time.

When forgetfulness is taken into account, the rate of memorization of a subject will no longer be a constant, but rather a declining function over time.

As time passes and new information is acquired, the previous information will start to fade from memory, leading to a decline in the overall rate of memorization.

This decline in the rate of memorization can be described mathematically as a function of time, where the rate of memorization decreases as time passes. This can be modeled using a variety of mathematical functions, such as exponential decay or logistic growth, depending on the specifics of the situation.

The exact form of the function will depend on factors such as the rate of forgetfulness, the intensity of memorization, and the time frame over which the information is being acquired and forgotten.

In a random sample of 300 adults, how many consume at least 320 mg of caffeine Daily. Of the 300 adults, approximately_________ adults consume at least 320 mg of caffeine daily.

The formula for a z-score is

\(z = (X - μ) / σ,\)

where X is the score you are interested in, μ is the mean of the population, and σ is the standard deviation.

μ = 250, σ

= 47, and X

= 320z

= (X - μ) / σ

= (320 - 250) / 47

= 1.4893

To find the probability of a z-score, we can look it up on a standard normal distribution table. Because we want the probability of a value greater than 320, we will use the right-tail probability, which can be found by subtracting the z-score from 1.

P(z > 1.4893)

= 1 - 0.9319

= 0.0681

The probability that an adult consumes at least 320 mg of caffeine is 0.0681, or 6.81%.

Answer: I think it would be C.. not sure tho

Step-by-step explanation:

The temperature at the start of the experiment is 10 degrees Celsius.

The rate of change of temperature during the first three seconds is -12 degrees Celsius per second.

The rate of change of temperature remains constant at -12 degrees Celsius per second after three seconds.

It can be inferred that the liquid does not reach a maximum temperature.

The temperature decreases over time, and there is no highest point or peak temperature mentioned in the given equation.

We have,

The given equation is T(t) = -12t + 10, where t represents time in seconds and T represents the temperature in degrees Celsius.

1)

The temperature at the start of the experiment (t = 0):

To find the temperature at the start of the experiment, substitute t = 0 into the equation:

T(0) = -12(0) + 10

T(0) = 0 + 10

T(0) = 10

2)

Rate of change of temperature during the first three seconds (0 ≤ t ≤ 3):

The rate of change of temperature can be determined by finding the derivative of the equation with respect to time, t. The derivative of -12t + 10 is -12.

3)

Rate of change of temperature after three seconds (t > 3):

Since the derivative of -12t + 10 is a constant (-12), the rate of change of temperature remains constant at -12 degrees Celsius per second after three seconds.

4)

Time at which the liquid reaches the maximum temperature:

The given equation T(t) = -12t + 10 represents a linear function where the temperature decreases over time. Since there is no maximum temperature mentioned in the equation, it can be inferred that the liquid does not reach a maximum temperature.

5)

The maximum temperature reached:

As stated above, the liquid does not reach a maximum temperature.

The temperature decreases over time, and there is no highest point or peak temperature mentioned in the given equation.

Thus,

The temperature at the start of the experiment is 10 degrees Celsius.

The rate of change of temperature during the first three seconds is -12 degrees Celsius per second.

The rate of change of temperature remains constant at -12 degrees Celsius per second after three seconds.

It can be inferred that the liquid does not reach a maximum temperature.

The temperature decreases over time, and there is no highest point or peak temperature mentioned in the given equation.

The expression that can be used to show how much money Rich earns in 8 weeks is: 8 * $35.

Rich earns $35 per week mowing lawns in his neighborhood.

We want to find out how much money he earns in 8 weeks.

To find the total amount of money Rich earns in 8 weeks, you can multiply the amount he earns per week ($35) by the number of weeks (8). This is because each week, Rich earns $35, so in 8 weeks, he will earn 8 times that amount.

So, the expression to calculate how much money Rich earns in 8 weeks is 35 dollars/week * 8 weeks.

By multiplying the amount earned per week by the number of weeks, we can determine the total earnings over the given period. In this case, Rich would earn a total of $280 in 8 weeks by mowing lawns in his neighborhood.

The slope of the tangent line to the curve at the point where t = 1 is 9.

To determine the slope of the tangent line to the curve defined by the parametric equations x(t) = 2t^3 - t^2 + 6t and y(t) = 9e^(6t - 6) at the point where t = 1, we can use the concept of differentiation.

First, let's find the derivative of x(t) and y(t) with respect to t:

dx(t)/dt = d/dt (2t^3 - t^2 + 6t)

= 6t^2 - 2t + 6

dy(t)/dt = d/dt (9e^(6t - 6))

= 54e^(6t - 6)

Next, we need to evaluate these derivatives at t = 1:

dx(1)/dt = 6(1)^2 - 2(1) + 6

= 6

dy(1)/dt = 54e^(6(1) - 6)

= 54e^0

= 54

Now, we have the slope of the tangent line at t = 1, which is given by dy(1)/dx(1). So, let's calculate that:

dy(1)/dx(1) = dy(1)/dt / dx(1)/dt

= 54 / 6

= 9

Therefore, the slope of the tangent line to the curve at the point where t = 1 is 9.

It's important to note that the slope represents the rate of change of y with respect to x at that specific point on the curve.
