Answer:

625, 125, 25, 5

Step-by-step explanation:

390625, 78125, 15625, 3125

We need to find out the relationship between a number and the previous number.

We can tell that there is no common difference since 78125 - 390625 cannot possibly equal 3125 - 15625.

We can try to check if this is a geometric sequence.

78125/390625 = 0.2

15626/78125 = 0.2

3125/15625 = 0.2

Each number is 1/5 of the previous number.

3125/5 = 625

625/5 = 125

125/5 = 25

25/5 = 5

Answer: 625, 125, 25, 5

The time it takes Timothy to drive to his friend's house does not proportional to the distance. Because all ordered pairs do not pass through a straight line.

What is the ordered pair?

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), with two values, expressed between parenthesis in a predetermined order. It aids visual comprehension by locating a point on the Cartesian plane. An ordered pair's numeric values can be integers or fractions.

Given ordered pairs are (5,10), (11,15), and (18,20).

The ordered pairs are plotted on the graph.

A line can not draw through the ordered pairs.

Thus, time is not proportional to distance.

Answer: A C A B

Step-by-step explanation:

(a) We know that 30% of the members of the club are female and 20% of these females own cars, and 30 female members own cars.

We can use this information to calculate the total number of female members in the club.

If 30% of the members are female and 20% of these females own cars,

then 20/100*30 female members = 6% of the total members own cars.

This means that 6% of the total members are female members who own cars.

Therefore, 30 female members / 6% = 500 female members.

So there are 500 female members in the club.

(b) If 30% of the members are female, then the total number of members is (100/30)*500 female members = 1666.67 members

(c) To increase the percentage of female members to 37.5%, we need to calculate the number of additional female members required to reach this goal. The current percentage of female members is 30% and we want to increase it to 37.5%. Therefore, we need an additional 37.5-30 = 7.5%. If the current number of female members is 500, to increase the percentage by 7.5%, we need an additional of 7.5/100*1666.67 = 125 additional female members.

At 2.5 seconds the ball reach its maximum height.

And, Its maximum height will be 25 feet.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation that describes the height (h) of a ball that is thrown straight up as a function of the (t) that the ball has been in the air is,

⇒ h = 40t - 16t²

So, For the time does the ball reach its maximum height, we can put h = 0, so we get;

⇒ h = 40t - 16t²

⇒ 40t - 16t² = 0

⇒ 16t² - 40t = 0

⇒ t (16t - 40) = 0

⇒ 16t - 40 = 0

⇒ 16t = 40

⇒ t = 40/16

⇒ t = 2.5 seconds

Now, The height function is a quadratic function which has the zeroes at  t = 0 and t = 2.5.

So, It has the maximum at x = midpoint between the roots 0 and 2.5, i.e. 1.25 seconds.

Hence, Substitute this value t = 1.25 seconds into the given height function, we get;

⇒ h = 40t - 16t²

⇒ h = 40 × 1.25 - 16 (1.25)²

⇒ h = 50 - 25

⇒ h = 25 feet

The requried dimension of the original rectangle is given as length = 25 cm, width = 10 cm.

The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.

Let the length and width of the original rectangle be x and y,
According to the quesiton,

The perimeter of a rectangle is 70 cm.
2 [x + y] = 70
x  + y = 35 - - - -(1)

Now,
its length is decreased by 5 cm and its width is increased by 5 cm, its area will increase by 50 cm².
Area of the new rectangle = area of the original rectangle + 50
(x  - 5)(y + 5) = xy + 50

from equation 1,

(x - 5)(35 - x + 5) = x(35 - x) + 50
-x² - 200 + 40x + 5x = 35x - x² + 50
45x - 35x = 50 + 200
10x = 250
x = 25

Now,
y = 35 - 25
y = 10

Answer:

x<4

Step-by-step explanation:

To solve and make the problem less intimidating, it is easier to just imagine that the < is a = sign. The only difference when solving a inequality versus an equation is that you flip the inequality sign when multiplying or dividing by a negative, which we won't need to worry about in this problem. Now, hopefully, this will make more sense when we are solving.

The first step is to add 20 to both sides:

15x - 20 < 40 (Add 20 to both sides)

15x < 60

Now, divide both sides by 15, so we are juts left with x:

15x < 60 (Divide both sides by 15)

x < 4

So, the inequality is true for any x value that is less than 4, or x<4.

Answer: To find point Q on the line segment PR that partitions it into the segments PQ and QR in the ratio 4:5, we need to use the concept of proportion.

We can set up the proportion as:

PQ / QR = 4 / 5

To find the actual point Q on the line segment PR, we need to know the coordinates of points P and R. Without them, it is not possible to find the point Q. Once we have the coordinates of P and R, we can use the proportion above to find the coordinates of Q.

Alternatively, we can use the concept of a "partitioned ratio" which is a way to split a line segment into a certain ratio. It is found by adding the two ratios together and then dividing the length of the line segment by that number. In this case (4+5 =9) and then PQ = (4/9) * PR and QR = (5/9) * PR.

No, these measurements do not form a triangle. The sum of any two sides of a triangle must be greater than the third side. In this case, 7 cm + 8 cm = 15 cm, which is not greater than the third side, 9 cm.

A triangle is a three-sided polygon, and all three sides must meet certain criteria in order to form a triangle. Specifically, the sum of any two sides must be greater than the third side. In this case, the given measurements are 7 cm, 8 cm, and 9 cm. When adding the 7 cm and 8 cm together, the sum is 15 cm, which is not greater than the third side, 9 cm. Therefore, these measurements do not form a triangle. To determine if a triangle can be formed with any given measurements, one must sum any two sides and ensure that the sum is greater than the third side. If the sum is not greater than the third side, then the measurements do not form a triangle.

The graph of the reflected function: g(x) = 3^(-x) can be seen in the image at the end.

First, for any function y = f(x), a reflection across the y-axis is written as:

g(x) = f(-x)

So we only change the sign of the argument of the function.

The graphed function is the parent function:

f(x) = 3^x

A reflection across the y-axis, will give the new function:

g(x) = f(x) = 3^(-x)
