Determine 7th term in the geometric sequence whose first term is 5 and whose common ratio is 2
The 7th term in the geometric sequence with a first term of 5 and a common ratio of 2 is found using the formula for the nth term of a geometric sequence. The 7th term is calculated to be 320.
The student has asked to determine the 7th term in a geometric sequence whose first term is 5 and whose common ratio is 2. To find this, we can use the formula for the nth term of a geometric sequence, which is an = a1 times rⁿ⁻¹, where a1 is the first term, r is the common ratio, and n is the term number.
To find the 7th term:
Identify that the first term (a1) is 5
The common ratio (r) is 2
Insert these values into the formula to get a7 = 5 times 2⁷⁻¹
Calculate the exponent: 2⁶ = 64
Multiply by the first term: 5 times 64 = 320
Therefore, the 7th term in the geometric sequence is 320.
at the Middleton school festival, a test covers a rectagularspace 30 1/2 yards long and 9 1/3 yards wide. what is the area, in square yards,covered by the tent?
Answer:
Multiply the length times width:
30 1/2 x 9 1/3= 284.6
Hence, the area of the rectangular space is:
284.6667 square yards.
Step-by-step explanation:It is given that the length(l) of the rectangular space is: [tex]30\frac{1}{2}\ yard[/tex] .
which in improper fraction is: [tex]\dfrac{61}{2}\ yard[/tex]
Similarly, the width(b) of the rectangular space is: [tex]9\frac{1}{3}\ yard[/tex]
which in improper fraction is: [tex]\dfrac{28}{3}\ yard[/tex]
As we know that the area of the rectangular space is calculated as:
[tex]Area=l\times b\\\\\\Area=\dfrac{61}{2}\times \dfrac{28}{3}\ \text{square\ yards}\\\\\\Area=284.6667\ \text{square\ yards}[/tex]
Hence, Area is: 284.6667 square yards.
Solve the equation.
4x – 6 = 2x – 2
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
Given: [tex]4x-6=2x-2[/tex]
To solve for x, we need to isolate the x values on one side of the equation. Let's start by subtracting 2x from both sides.
[tex]2x-6=-2[/tex]
To further isolate x on one side of the variable, we should add 6 to both sides.
[tex]2x=4[/tex]
Finally, we need to take the coefficient of 2 off of the x to solve for x. To do this, divide both sides by the coefficient, 2.
[tex]\frac{2x}{2} = \frac{4}{2}[/tex]
[tex]x=2[/tex]
Answer: x=2

one positive integer is 5 less than another. the product of the two integers is 24. what are the integers?
Final answer:
The two positive integers in question are 8 and 3, as they satisfy both conditions: one integer is 5 less than the other and their product equals 24.
Explanation:
The problem asks us to find two positive integers where one is 5 less than the other and their product equals 24. Let's denote the larger integer as 'x'. Then, the other integer would be 'x - 5'. We can set up the equation:
x(x - 5) = 24
Which simplifies to:
x² - 5x - 24 = 0
By factoring this quadratic equation, we end up with:
(x - 8)(x + 3) = 0
We are given the numbers are positive integers, so we take the positive root which is:
x = 8
Subsequently, the smaller integer would be:
8 - 5 = 3
So the two integers are 8 and 3.
the numbers 30 to 74 are in a hat. If the probability of drawing a multiple of 2 is 23/45. What is the probability of not drawing a multiple of two?
Answer:
22/45
Step-by-step explanation:
Let A be the event of drawing a multiple of 2,
So,
p(A)= 23/45
Now, let A' be the opposite(complementary) event which means not drawing a multiple of 2
From the properties of probability, the sum of an event’s probability and its opposite(complementary) event’s probability is equal to 1.
p(A)+p(A')=1
We have to find the probability of not drawing a multiple of two i.e. p(A')
p(A')=1-p(A)
=1 - 23/45
= (45-23)/45
=22/45
So the probability of not drawing a multiple of 2 from the hat is 22/45.
Final answer:
The probability of not drawing a multiple of two from the numbers 30 to 74, given the probability of drawing a multiple of two is 23/45, is computed by subtracting 23/45 from 1, resulting in a probability of 22/45.
Explanation:
The probability of not drawing a multiple of two is simply calculated by subtracting the probability of drawing a multiple of two from 1, as these probabilities are complementary.
Given that the probability of drawing a multiple of 2 is 23/45, we can find the probability of not drawing a multiple of two by doing the following:
1 - (probability of drawing a multiple of 2) = 1 - (23/45) = 22/45.
Therefore, the probability of not drawing a multiple of two is 22/45.
What is the equation of the graph below?
The equation of the graph is y= -(x+3)^2 +1
Choice A is the correct answer
The equation of the given graph is:
[tex]y=-(x-3)^2+1[/tex]
Step-by-step explanation:We know that the general equation of a downward parabola with vertex at (h,k) is given by the formula:
[tex]y=a(x-h)^2+k[/tex]
where a<0
Here in each of the options we have a= 1 or -1
but as a has to be less than 1 this means that a= -1
Also, we have: (h,k)= (3,1)
i.e. h=3 and k=1
Hence, putting the values of h,k and a in the general equation we get:
Hence, the equation of parabola is:
[tex]y=-(x-3)^2+1[/tex]
A bicylcle shop designs a new gear system for their bikes.They use a 4-inch gear for the bikes with a 22-inch wheel diameter. If the ratio of the gear to wheel diameter remains constant, what is the size of the gear for a bike with a 26-inch wheel?
Answer:
8
4 --
11
Step-by-step explanation:
The gear ratio for the original gear system was 4/22. To get the 22 inch wheel to 26 inches, you have to multiply it by 26/22, so to keep the same ratio, you will also need to multiply 4 by 26/22. You get 104/22, which simplifies to 52/11 which simplified further to 4+8/11. You can check your answer by comparing the original ratio to the new ratio.
Using the principle of constant proportion, the new gear size for a bike with a 26-inch wheel while maintaining the original gear-to-wheel diameter ratio is approximately 4.73 inches.
Explanation:The student asked about the gear size for a bike with a 26-inch wheel if the existing bike uses a 4-inch gear with a 22-inch wheel diameter, and the ratio of the gear size to the wheel diameter is constant.
To find the new gear size, we set up a proportion using the given gear and wheel sizes:
4 inches (gear) / 22 inches (wheel) = x inches (new gear size) / 26 inches (new wheel size).Cross-multiplying to solve for x gives us:
4 inches * 26 inches = 22 inches * x inches
104 = 22x
x = 104 / 22
x = 4.727272... inches
So, the new gear size would be approximately 4.73 inches if we maintain the same ratio for a bike with a 26-inch wheel.

58.5, 59, 59, 59.5, 60, 60, 60.5, 61, 63, 72
Mrs. Blackwell's class is getting a new student next week. The current students want to predict the height of the new student. They record the height of everyone in the class. Which measure of center should they use to make the prediction and what should be their prediction?
A) the mean and they should predict 59 inches
B) the mean and they should predict 58.5 inches
C) the median and they should predict 59 inches
D) the median and they should predict 58.5 inches
Answer: D. The Median and they should predict 58.5 inches.
Step-by-step explanation: Before we start, we want to use median. This is because there is an outlier, 72, and that would mess up the mean by a small yet noticeable margin.
Since the median picks both numbers 58.5 and 58.5, that means that the answer will be D. The Median and they should predict 58.5 inches.
Answer:
D The median and they should predict 58.5
Step-by-step explanation:
If you count from the outsides and go to the inside with a pencil or you're fingers then you get 58.5 :D

Which of the following functions best represents the graph?
f(x) = x3 + x2 − 4x − 4
f(x) = x3 + 4x2 − x − 4
f(x) = x3 + 3x2 − 4x − 12
f(x) = x3 + 2x2 − 4x − 8
Answer:
[tex]f(x)=x^3+x^2-4x-4[/tex]
Step-by-step explanation:
From the graph, the x-intercepts are;
[tex]x=-2[/tex]
[tex]x=-1[/tex]
[tex]x=2[/tex]
These are root of the polynomial function represented by the given graph.
By the remainder theorem;
[tex]f(-2)=0,f(-1)=0,f(2)=0[/tex]
According to the factor theorem, if [tex](x-a)[/tex] is a factor of [tex]f(x)[/tex], then [tex]f(a)=0[/tex]
This implies that;
[tex](x+2),(x+1),(x-2)[/tex] are factors of the required function.
Hence; [tex]f(x)=(x+1)(x-2)(x+2)[/tex]
We expand using difference of two squares to obtain;
[tex]f(x)=(x+1)(x^2-4)[/tex]
We expand using the distributive property to get;
[tex]f(x)=x^3-4x+x^2-4[/tex]
Rewrite in standard form to obtain;
[tex]f(x)=x^3+x^2-4x-4[/tex]
Answer:
Choice A: f(x) = x^3 + x^2 − 4x − 4
Step-by-step explanation:
Here's a great and simple answer.
Ok first we need to take the x intercepts to solve.
If we look at the graph we see the x ints are -2,+1 and +2.
To solve we need to put them into factor form
= (x-2) (x+2) and (x+1)
Simplify: (x-2) (x+2) = (x^2-4) and (x+1)
Now we take (x^2-4) and (x+1) and multiply them to find our answer
(x^2-4) (x+1)
= x^2(x) and x^2(1) = x^3 and x^2.
now the other: -4(x) and -4(+1) = -4x and -4
We have nothing common here so we just join them
= x^3 + x^2 - 4x - 4, and that is the same as choice A.

B. 360 miles in 7 hours
C. 111 miles in 2 hours
D. 283 miles in 5 hours
Answer:
D - 56.6 MPH is the faster
Step-by-step explanation:
Find the unit rate by dividing the miles by hours
A. 589/11 = 53.55 MPH
B. 360/7 = 51.43 MPH
C. 111/2 = 55.5 MPH
D. 283/5 = 56.6 MPH
After calculating the speed for each option by dividing the distance by time, option D is found to be the fastest with a speed of 56.6 mph.
Explanation:To find out which rate is the fastest, we need to calculate the speed for each option by dividing the distance by the time.
The speed is the distance traveled per unit of time, typically expressed in miles per hour (mph).
For option A, the speed is 589 miles / 11 hours = 53.55 mph.For option B, the speed is 360 miles / 7 hours = 51.43 mph.For option C, the speed is 111 miles / 2 hours = 55.5 mph.For option D, the speed is 283 miles / 5 hours = 56.6 mph.Comparing the calculated speeds, option D is the fastest with a speed of 56.6 mph.

The equation that represents an inverse variation with a constant of 56 is:
Option: D
D. [tex]\dfrac{xy}{2}=28[/tex]
Step-by-step explanation:Inverse Variation--
It is a relationship between two variables such that it is given in the form that:
If x and y are two variables then they are said to be in inverse variation if there exist a constant k such that:
[tex]y=\dfrac{k}{x}[/tex]
i.e.
[tex]xy=k[/tex]
Here the constant of variation is 56
i.e. k=56
Hence, we have:
[tex]xy=56\\\\i.e.\\\\xy=28\times 2\\\\i.e.\\\\\dfrac{xy}{2}=28[/tex]
Hence, option: D is the correct answer.
