Find the 6th term of the geometric sequence represented below. 3. 1, 0.5, 0.25, ...

Answers

Answer: Hi I  Can not seem to calculate the answer but I can give you a way to find 6th term or the geomatric sequence.

By substituting the values for a, r and n we can find the desired term that we want. r=7525, cancelling out the common factors, we get r=3. As we want the 6th term to find, substituting n=6,r=3&a=25 in the above equation, we get (25)(3)6−1. Simplifying this expression, we get 6075.

Graph y=6x−7
Identify the x-intercept.

Answers

9514 1404 393

Answer:

  x-intercept: 7/6

Step-by-step explanation:

The x-intercept is found by solving for x when y=0.

  0 = 6x -7

  7 = 6x . . . . . add 7 to both sides of the equation

  7/6 = x . . . . divide both sides by 6

The x-intercept is 7/6 = 1 1/6 ≈ 1.167.

__

The y-intercept is the constant in the given equation: -7. The slope of 6 tells you the line rises 6 units for 1 unit to the right. So, the point (1, -1) is another point on the graph. The line through those two points, (0, -7) and (1, -1), will intersect the x-axis at x=7/6.

D the Radius, r

Answers

The base of the parallelogram formed from the circle is half the circumference or πr .

A circumference is the length of the circle which is the perimeter of the circle.

The circumference of the circle can be given by the formula C = 2πr , where r is the radius of the circle.

If a circle is divided into equal sectors then the approximate size of the polygon formed by rearranging the sectors is a parallelogram.

The base of the parallelogram will be half of the circumference , or

base = 0.5 × 2 πr = πr

And the height will be the radius r of the circle.

Now area of a parallelogram is given by  base × height

Now area = πr × r = πr²

Therefore the area of the circle is πr² .

Hence the base of the parallelogram formed from the circle is half the circumference or πr .

The number of points, Jaden scored in a game is less than 45, and is also a multiple of 7. How many points could Jaden have scored?

Answers

Answer:

Jaden could have scored 0, 7, 14, 21, 28, 35 or 42 points.

Step-by-step explanation:

Multiples of 7 less than 45:

7*0 = 0

7*1 = 7

7*2 = 14

7*3 = 21

7*4 = 28

7*5 = 35

7*6 = 42.

7*7 = 49(above 49 so does not count in the context of this question).

Answers

Answer:

-1/2, 7

Step-by-step explanation:

Given the expression

(x -7)(-4x -2)=0

This means that;

x - 7  = 0 and -4x - 2 = 0

x = 0+7 snd -4x = 2

x = 7 and x =  -2/4

x = 7 and -1/2

The expression 3t gives the number of tickets a player wins if he shoots the ball in the hoop t times. How many tickets would a player win if he shoots the ball in the hoop 16 times

Answers

Answer: 48 tickets

Step-by-step explanation:

Since the expression that gives the number of tickets a player wins if he shoots the ball in the hoop t times is expressed as 3t.

Therefore, the number of tickets that a player wins if he shoots the ball in the hoop 16 times will be:

= 3t

where,

t = 16

Therefore, 3t = 3 × 16 = 48

The player wins 48 tickets.

Shift 4 units to the right.
• Shift 6 units up.
A. g(x) = 5x + 6 + 4
B. g(x) = x - 41 + 6
C. g(x) = 1x - 61 + 4
D. g(x) = 5x + 4 + 6

Answers

Answer:

B

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Here f(x) is shifted 4 units to the right , so

g(x) = | x - 4 |

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here f(x) is shifted 6 units up , so

g(x) = | x - 4 | + 6 → B

The simplified equation for the new function is g(x) = |x - 4| + 6.

What is translation?

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

The absolute value parent function is f(x) = |x|.

To shift 4 units to the right, we replace x with (x - 4) since we want the graph to move 4 units to the right.

To shift 6 units up, we add 6 to the entire function since we want the graph to move 6 units up.

So the equation of the new function g(x) is:

g(x) = |x - 4| + 6

Thus,

The simplified equation for the new function is g(x) = |x - 4| + 6.

So what is slope?

Slope is the change in y over the change in x.

You find the change in y and x when you compare two points on the line.

In this case, lets chose the two points they give us:

(1, -4) and (6, 1)

What is the difference of y? That looks like 5(1+4) or (1--4).

What is the difference of x? That looks like 5(6-1=5)

So we can tell the slope is y/x, or 5/5.

This can simpfly to 1.

So 1 is your slope!
