The length is 5 units more than the width. The perimeter is 9 times the width. Find the length and width of the rectangle. Can you also include the steps thanks!
The length, width, and perimeter of the rectangle are 7 units, 2 units, and 18 units.
What is the perimeter?Perimeter is the sum of the length of the sides used to make the given figure.
Let the width of the rectangle be represented by x. The length is 5 units more than the width. The perimeter is 9 times the width. Therefore, we can write,
Width = x
Length = 5 + x
Perimeter = 9x
Now, the length, width, and perimeter of the rectangle together can be written as,
Perimeter = 2(Length + Width)
9x = 2[(5+x) + x]
9x = 2(5 + x + x)
9x = 2(5 + 2x)
9x = 10 + 4x
9x - 4x = 10
5x = 10
x = 10/5
x = 2
Further, the dimensions can be written as,
Width = x = 2 units
Length = 5 + x = 2 + 5 = 7 units
Perimeter = 9x = 9(2) = 18 units
Hence, the length, width, and perimeter of the rectangle are 7 units, 2 units, and 18 units.

A golf ball is dropped from a height of 30 ft to the pavement, and the rebound is one fourth the distance it drops. if after each descent it continues to rebound one fourth the distance dropped, what is the distance the ball has traveled when it reaches the pavement on its tenth descent?
The question deals with a sequence of movements of a golf ball falling and rebounding, which forms a geometric series. To find the total distance traveled by the ball on its 10th descent, we calculate the sum of the first 19 terms of this geometric progression.
Explanation:The student is asking about a geometric series problem, which involves a golf ball being dropped from a height and rebounding to a fraction of that height. The sequence of the distances covered by the ball forms a geometric progression.
Let's denote the initial height the ball is dropped from as a, which is 30 ft. The rebound height is one-fourth of the descent, so the rebound ratio, or common ratio r, is 1/4. The ball travels the initial height a plus the rebound distance each time it hits the pavement. This series continues with each rebound being one-fourth of the previous fall. We want to find the total distance traveled by the ball as it hits the pavement on its 10th descent.
The total distance traveled D after the ball hits the pavement for the 10th time is the sum of the first 10 terms of this geometric sequence. Using the formula for the sum of the first n terms of a geometric series, [tex]S_n = a(1-r^n)/(1-r)[/tex], where n is the number of terms, we can calculate the total distance.
For 10 descents, we have n = 19 since each descent and rebound except
the last descent counts as two movements:
[tex]S_{19} = 30(1-(1/4)^{19})/(1-(1/4))[/tex]
[tex]S_{19} = 30(1-(1/4)^{19})/(3/4)[/tex]
By calculating [tex]S_{19[/tex], we find the total distance traveled when the ball hits the pavement on its 10th descent.

1996 gail devers won the 100-meter dash in the olympic games. her times was 10.94 seconds. what was her speed in meters per second?
Solving this problem is just pretty straight forward. We simply have to get the ratio of distance and time to get the speed. that is:
speed = distance / time
speed = 100 m / 10.94 s
speed = 9.14 m/s
Final answer:
Gail Devers' average speed during her Olympic win in the 100-meter dash with a time of 10.94 seconds is calculated to be approximately 9.14 meters per second using the formula speed = distance/time.
Explanation:
In 1996, Gail Devers won the 100-meter dash in the Olympic Games with a time of 10.94 seconds. To find her average speed in meters per second, we use the formula:
s = d / t
where s is speed, d is distance, and t is time. Given that the distance (d) is 100 meters and the time (t) is 10.94 seconds, we can calculate the average speed:
s = 100 m / 10.94 s ≈ 9.14 m/s
Therefore, Gail Devers' average speed during her Olympic 100-meter dash victory was approximately 9.14 meters per second.

1. If x-1 is a factor of p(x)=x^3-7x^2+15x-9, which of the following represents the complete factorization for p(x)?
A. (x-3)(x+4)(x+1)
B. (x-3)(x-3)(x-1)
C. (x-3)(x+3)(x-1)
D. (x-3)(x+3)(x+1)
2. The point (1,0) lies on the graph of p(x)=x^4-2x^3-x+2
True or false
Answer:
1. Option B is the correct answer.
2. The point (1,0) lies on the graph of p(x)=x⁴-2x³-x+2.
Step-by-step explanation:
1. Dividing x³-7x²+15x-9 with (x-1).
[tex]\frac{x^3-7x^2+15x-9}{x-1}=x^2-6x+9[/tex]
Factorizing x²-6x+9 we will get
x²-6x+9 = (x - 3)(x-3)
x³-7x²+15x-9 = (x-1)(x - 3)(x-3)
Option B is the correct answer.
2. We have p(x)=x⁴-2x³-x+2
That is y = x⁴-2x³-x+2
We have coordinates (1,0), substituting
y = 1⁴-2 x 1³-1+2 = 0
So when we are substituting x value as 1 we are getting y as zero, so the point lies in curve.

What is the solution to the system of linear equations?
6x+7y=59
4x+5y=41 how do you do it
Answer:
The correct answer is 4, 5 :)
Step-by-step explanation:
A system of linear equations can be solved by elimination, substitution or using graphs.
The values of x and y for [tex]6x + 7y= 59[/tex] and [tex]4x + 5y =41[/tex] are 4 and 5, respectively.
Given
[tex]6x + 7y= 59[/tex]
[tex]4x + 5y =41[/tex]
Make x the subject in [tex]4x + 5y =41[/tex]
[tex]4x = 41 - 5y[/tex]
Divide by 4
[tex]x = \frac 14(41 - 5y)[/tex]
Substitute [tex]x = \frac 14(41 - 5y)[/tex] in [tex]6x + 7y= 59[/tex]
[tex]6 \times \frac 14(41 - 5y)+ 7y = 59[/tex]
[tex]\frac 32(41 - 5y)+ 7y = 59[/tex]
Multiply through by 2
[tex]2 \times \frac 32(41 - 5y)+ 2 \times 7y = 2 \times 59[/tex]
[tex]3(41 - 5y)+ 14y = 118[/tex]
Open brackets
[tex]123 - 15y+ 14y = 118[/tex]
Collect like terms
[tex]- 15y+ 14y = 118 - 123[/tex]
[tex]-y = -5[/tex]
[tex]y = 5[/tex]
Substitute [tex]y = 5[/tex] in [tex]x = \frac 14(41 - 5y)[/tex]
[tex]x = \frac 14(41 - 5 \times 5)[/tex]
[tex]x = \frac 14(41 - 25)[/tex]
[tex]x = \frac 14(16)[/tex]
[tex]x = 4[/tex]
Hence, the solution to the system of linear equations is:
[tex]x = 4[/tex]
