A recursive rule for a sequence is given. Find the first four terms of the sequence.
f(1) = 2
f(n) = 4. f(n – 1), where n is an integer and n > 2.

Answers

Answer 1

Answer:  

So...

   a0 = -2

   a1 = (a0)2 - 4  =  4 - 4  =  0

   a2 = (a1)2 - 4 = ((a0)2-4)2 - 4 =...=  02 - 4  = -4  

       For an+1, you may use the previous term (an) if you have just calculated it, rather than calculating it recursively again

   a3 = (-4)2 - 4 = 12

 

The first four terms in the sequence are -2, 0, -4, 12.

Step-by-step explanation:

This recursive sequence is defined as follows:

 a0 = -2      [the first term]

 an+1 = an2 - 4     [for all other terms, n≥0; note that you cannot find a0 using this line]

 

Note that this is not "BASE" for a number base, but it is "SUB" for subscript, indicating the term.  Sometimes, sequences are written with the first term being a1 and sometimes sequences are written with the first term being a0.  This is because there are situations that make one or the other more convenient (for example, starting with elapsed time t=0 makes sense).

 

To find the value of later terms, a recursive definition requires that you find the value of the previous term, which requires that you find the value of the previous term, which requires that you find the value of the previous term, which requires that you find the value of the previous term, ... which requires that use the value of the first term.

 

That's why (joke) that the dictionary definition of "recursive" is "see recursive."

Your answer would be B: 30 ft squared

Step-by-step explanation:

Find the area of the circle: 5.5 (radius) multiply it by itself then multiply that by 3.14 which gets you 94.985. Now find the area of the square which is 8*8 = 64. Subtract 64 from 94.985 and your answer will be 30.985. The questions asks for the approximate (estimate), so the closest one would be 30 ft squared

Write equations for the vertical and horizontal lines passing through the point (0, -3).

Answers

Answer:

Vertical line will be x=0, and horizontal line will be y=-3

Step-by-step explanation:

Draw a vertical line through point (0,-3). You will see it's on the y-axis. The equation of the line on y-axis is always x=0, because no matter what point you choose on the line, the x coordinate will be 0. (0,-3), (0, -2), etc.

Next draw a horizontal line through (0,-3). It's parallel to the x axis, and no matter what point on the line you choose, the y coordinate will be -3. (0,-3), (1, -3), etc

The equation for the vertical line is x=8 and the horizontal line is y=−7.

The given coordinate point is (0, -3).

What are the vertical and horizontal lines?

A vertical line is a line, parallel to the y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to the x-axis and goes straight, left and right.

Now,

For a vertical line the value of x, in this case, 8, will never change. This will be true for any value of y. Therefore the equation for a vertical line passing through this point is: x=8

Likewise, for a horizontal line the value of y, in this case, −7, will never change. This will be true for any value of x. Therefore the equation for a horizontal line passing through this point is: y=−7

Therefore, the equation for the vertical line is x=8 and the horizontal line is y=−7.

What is the slope of a line represented by 3x-14y=28

Answers

Answer:

3/14

Step-by-step explanation:

3x-14y=28

solve

add -3 both sides

3x−14y+−3x=28+−3x

−14y=−3x+28

divide both sides by -14

y= 3 /14 x−2

y=mx+b

so 3/14 is the slope

Answer:

[tex] y = -\frac{10}{3}x - 23 [/tex]

Step-by-step explanation:

Find slope (m) using of the line that passes through (-9, 7) and (-6, -3).

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 7}{-6 -(-9)} = \frac{-10}{3} = -\frac{10}{3} [/tex]

Find y-intercept (b) by substituting m = -10/3, x = -6, and y = -3 in y = mx + b.

Thus:

-3 = (-10/3)(-6) + b

-3 = 20 + b

Subtract 20 from each side

-23 = b

b = -23

substitute m = -10/3, and b = -23 in y = mx + b, to get the equation.

The equation of the line would be:

✅ [tex] y = -\frac{10}{3}x + (-23) [/tex]

[tex] y = -\frac{10}{3}x - 23 [/tex]

There are 125 people on a mountain trail. If 84% of the people on the trail are on a hiking tour, how many people are on the tour

Answers

Answer:

Total people on the tour will be: 105 people

Step-by-step explanation:

Total people on a mountain trail = 125

Given that 84% of the people on the trail are on a hiking tour.

We need to determine how many people are on the tour.

All we need is to multiply 84% or 0.84 by 125.

i.e.

People are on the tour = 84% × 125

                                      = 84/100 × 125

                                      = 0.84 × 125

                                      = 105 people

Therefore, total people on the tour will be: 105 people

According to a survey in one U.S. city, 53% of women between the ages and 25 of 35 are married, 45% are working full time, and 21% are married and working full time. If a woman between the ages of 25 and 35 is picked at random from the city, what is the probability that she is working full time or married but not both

Answers

Answer: 56%

Step-by-step explanation:

given data:

married women between 25 and 35 = 53%

working full time = 45%

married  and working full time = 21%

Solution:

= 53% - 21%

= 32%

= 45% - 21%

= 24%

probability that she is working full time or married but not both

= 32% + 24%

= 56%

When a fair 6 sided dice is rolled, what is the probability that is will land on the five?

Answers

Answer:

1/6

Step-by-step explanation:

Only one of the six sides is a 5 on the die. So there is a 1/6 chance that it will land on it

It would be 1/6 chance of it rolling on 5 because the dice has 6 sides, so if a dice has 8 sides then it would be a 1/8 chance to roll on any number
