Find the 7th term of the geometric progression which begins -6250, 1250, -250....

Answers

Answer 1

Answer:

a(7) = -0.4

Step-by-step explanation:

The general formula for a geometric progression is a(n) = a(1)*r^(n - 1), where r is the common ratio.  In this problem, a(1) = -6250.  To find r, we divide 1250 (the 2nd term) by -6250 (the 1st term), obtaining r = -0.2.

Then the formula for THIS geometric progression is

a(n) = -6250*(-0.2)^(n - 1).

Thus, the 7th term of THIS progression is

a(7) = -6250*(-0.2)^(7 - 1), or -6250*(-0.2)^6, or -0.4

Answer 2

Answer:

a₇ = - [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

The nth term of a geometric progression is

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 6250 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{1250}{-6250}[/tex] = - [tex]\frac{1}{5}[/tex] , then

a₇ = - 6250 × [tex](-\frac{1}{5}) ^{6}[/tex] = - 6250 × [tex]\frac{1}{15625}[/tex] = [tex]\frac{-6250}{15625}[/tex] = - [tex]\frac{2}{5}[/tex]

Draw the following triangle after a 90° clockwise rotation about the origin.

Answers

Answer:

Its gonna be in the same spot but just on the left

Step-by-step explanation:

The graph is attached with the solution

What is rotation?

Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.

The coordinates of the vertices of the given triangle are (3,-2), (1,-5), and (5,-4).

The coordinate rule for 90° clockwise rotation about the origin is:

(x,y)→(y,-x)

Therefore, the vertices of the triangle are transformed as follows:

(3,-2) → (-2, -3)

(1,-5) → (-5,-1)

(5,-4) → (-4,-5)

Now, plot the image points (-2,-3), (-5,-1), and (-4,-5) and connect them to draw the required triangle.

The graph is attached with the solution.

2. A kitten is gaining 0.6 pounds per week. The kitten is currently seven pounds. After how many weeks will the kitten be at least 10 pounds?

Answers

Answer:

Here is the answer

Step-by-step explanation:

The kitten weighs_____pounds every week                    -0.6 pounds

Weight of the kitten at current time                                    -7 pounds

Weeks it will take for the kitten to reach 10 pounds         -0.6+7=7.6

                                                       now round it off and you will get 7

                            ∴the kitten will take 7 more weeks for getting to 10 pounds            

The kitten will be at least 10 pounds after 5 weeks. Let's set up an equation to solve for the number of weeks needed for the kitten to reach at least 10 pounds.

Let "w" represent the number of weeks.

The weight of the kitten after "w" weeks can be calculated as:

Weight = Initial weight + (Weight gained per week * Number of weeks)

Weight = 7 + (0.6 * w)

We want to find the number of weeks when the weight is at least 10 pounds:Weight ≥ 10

Substituting the equation for weight:

7 + (0.6 * w) ≥ 10

Subtracting 7 from both sides:

0.6 * w ≥ 3

Dividing both sides by 0.6:

w ≥ 3 / 0.6

w ≥ 5

Therefore, the kitten will be at least 10 pounds after 5 weeks.

Quadrilateral ABCD is inscribed In a circle.
What is the measure of angle A?

Answers

Answer:

[tex] m\angle A = 133\degree [/tex]

Step-by-step explanation:

Quadrilateral ABCD is inscribed In a circle.

So, ABCD is a cyclic Quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

(4x + 5)° + (x + 15)° = 180°

(4x + 5 + x + 15)° = 180°

(5x + 20)° = 180°

5x + 20 = 180

5x = 180 - 20

5x = 160

x = 160/5

x = 32

[tex] m\angle A = (4x + 5)\degree [/tex]

[tex] m\angle A = (4\times 32+ 5)\degree [/tex]

[tex] m\angle A = (128+ 5)\degree [/tex]

[tex] m\angle A = 133\degree [/tex]
