What is the recursive formula for this geometric sequence? -3. -21, -147, -1029, …

Answers

Answer 1

Answer:

[tex]a_{n}[/tex] = 7[tex]a_{n-1}[/tex]

Step-by-step explanation:

A recursive formula allows a rem in the sequence to be found by multiplying the previous term by the common ratio r

For this sequence

r =  [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-21}{-3}[/tex] = 7 , then recursive formula is

[tex]a_{n}[/tex] = 7[tex]a_{n-1}[/tex]

You are able to walk uphill at a speed of 2 miles per hour and downhill at a speed of 3 miles per hour. What does the graph represent?

Answers

Using a piece-wise function, the representation of the graph is given as follows:

Walking uphill for 3 hours and downhill for 1 hour.

What is a piece-wise function?

A piece-wise function is a function that has multiple definitions, depending on the input.

In this problem, we have that:

For the first 3 hours, the slope is of 2 miles per hour, equivalent to walking uphill.For the final hour, the slope is of 3 miles per hour, equivalent to walking downhill.

Hence the meaning of the graph is:

Walking uphill for 3 hours and downhill for 1 hour.

Through how many degrees does the hour hand of a clock travel between 3:00pm and 3:15pm?

Answers

Answer: 90 degrees

Explanation: A clock is a circle, so overall it’s 360 degrees. It is divided by 60 separate minute marks. So to find the degree for each minute we divide 360 by 60 and get 6. This means each minute is work 6 degrees. Now we see that the time change between 3:00 and 3:15 is 15 minutes. So we need to multiply 15 by 6. This gives us 90 which is the final answer.

Answer:

90 degrees

Step-by-step explanation:

the clock is a circle so the entire # of degrees is 360.

there are 12 sections on the clock so 360 /12 =30

so each section is 30 degrees.

if you go from 3:00 to 3:15, that is 3 sections.

so 3 times 30 is 90

Based on a poll, 867 of 1050 randomly selected adult said that they always wear seat belts. Construct and interpret a 97% confidence interval for the proportion of adults who always wear seat belts.

Answers

The 97% confidence interval for the proportion of adults is 0.801<P<0.851.

Given that 867 adults are randomly selected from 1050 who always wear seat belts.

A confidence interval refers to the probability that a population parameter will fall between a set of values for a certain proportion of times.

Let's assume n=1050 and x=867

Find the sample proportion by dividing the given proportion with sample size as,

[tex]\begin{aligned}\hat{p}&=\frac{x}{n}\\\hat{p}&=\frac{867}{1050}\\ \hat{p}&=0.826 \end[/tex]

Find the α by subtracting the given confidence interval that is 97% from 1 as

α=1-(97÷100)

α=1-0.97

α=0.03

To find the critical value that is [tex]Z_{\frac{\alpha}{2}}[/tex] by dividing alpha with 2,

[tex]\begin{aligned}Z_{\frac{\alpha}{2}}&=Z_{\frac{0.03}{2}}\\ Z_{\frac{\alpha}{2}}&=Z_{0.015}\end[/tex]

From this table which is shown in the figure it says that the critical value is

[tex]Z_{crit}=\pm 2.17[/tex]

Use this formula to find the confidence interval [tex]P=\hat{p}\pm Z_{Crit}\times \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]

Substitute the values in the formula,

[tex]\begin{aligned}P&=0.826\pm 2.17\times \sqrt{\frac{0.826(1-0.826)}{1050}}\\ P&=0.826\pm 2.17\times \sqrt{\frac{0.826\times 0.174}{1050}}\\ P&=0.826\pm 2.17\times 0.0116995\\ P&=0.826\pm 0.025\end{aligned}[/tex]

Hence, a 97% confidence interval for the proportion of adults who always wear seat belts is 0.801<P<0.851.

Answer:

Step-by-step explanation:

I am going to answer this question in slope-intercept form, which is y = mx + b (m is the slope, b is the y-intercept). The question already gives us the y-intercept, or the point at which the graph crosses the y-axis. It is (0, 0). Now, all we have to do is find the slope, which we can do using the following formula:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

In this formula, (x1, y1) and (x2, y2) are two points that are given to us [the first point is (0,0) and the second point is (2,-3). We can solve for the slope by plugging in:

[tex]m=\frac{-3-0}{2-0}=\frac{-3}{2}[/tex]

Now that we have m and b, we can plug into slope-intercept form to get our equation: y = (-3/2)x + 0 or y = (-3/2)x

By the vertex form of the parabola, the equation of the parabola shown in the diagram is equal to the quadratic equation y - 1 = (2/3) · (x - 3)².

How to determine the equation of the parabola in vertex form

Parabolae are represented mathematically by second order polynomials, which can be described either in standard form or in vertex form. In accordance to the picture, we have a parabola with a vertical axis of symmetry. The formula in vertex form is described by this expression:

y - k = C · (x - h)²

Where:

(h, k) - Coordinates of the vertex.C - Vertex constant

Please notice that vertices represent the absolute extreme of the parabola. We can determine the equation by knowing the vertex and another point. Let be (h, k) = (3, 1) and (x, y) = (0, 7), then we find that the vertex constant is:

7 - 1 = C · (0 - 3)²

6 = 9 · C

C = 2/3

How can you quickly determine the number of roots a polynomial will have by looking at the equation?

Answers

One can determine the number of roots by seeing the degree of the given polynomial.

The number of roots can be determined by just seeing the highest power of the given equation.

1) for the equation  x-4=0

here, the highest power of the equation is one. So, it will have one root.

What is the polynomial?

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtract multiplication, on,  and non-negative integer exponentiation of variables.

Let's check it by simplifying x-4=0  which implies x=4

Hence, the equation has only one root namely x = 4.

2) Consider a quadratic equation,

10t^2-t-3=0

here, the highest power of the equation is two. So, it will have two roots.

Let's check it by simplifying using the middle term splitting method,

10t^2+5t-6t-3=0

5t(2t+1)-3(2t+1)=0

(5t-3)(2t+1)=0

t=-3/5 or t=-1/2

Thus, the equation has two roots.

Hence, one can determine the number of roots by seeing the degree of the given polynomial.
