Answers

Answer 1
c. neither arithemtic nor geometric
Answer 2
ANSWER

C)neither arithmetic nor geometric

EXPLANATION

The given sequence is

[tex]99,89.9,78.8,68.7,...[/tex]

Let us check to see if there is a constant difference.

[tex]89.9 - 99 = - 9.1[/tex]

[tex]78.8 - 89.9 = - 11.1[/tex]


The two difference are not the same.

Since there is no constant difference, the sequence is not arithmetic.


Let us check to see if there is a common ratio,

[tex] \frac{89.9}{99} = \frac{899}{990} [/tex]


[tex] \frac{78.8}{89.9} = \frac{788}{899} [/tex]

Since the ratio is not the same,the sequence is not geometric too.


The sequence is neither arithmetic nor geometric.


The correct answer is C

Answers

1. A
Two triangles are said to be in perspective (or as some would call it, homologous) from a point if their corresponding vertices form three lines that intersect in that single point (called a colinear point). Desargues' theorem asserts that if two triangles are in perspective from a point, then they are also perspective from a line (called the perspectrix); for this reason perspective triangles are also calles coplanar triangles.

a volleyball reaches its maximum height of 13 feet, 3 seconds after its served. Which of the following quadratics could model the height of the vollyball over time after it is served. Select all that apply.

A: f(x)=2x^2+12x+5

B: f(x)=-2x^2+12x-5

C: f(x)=-2x^2-12x+5

D: f(x)=-2(x-3)^2+13

E: f(x)=-2(x+3)^2+13

Answers

Only selections B and D give a maximum height of 13 at t=3. However, both of those functions have the height be -5 at t=0, meaning the ball was served from 5 ft below ground. This does not seem like an appropriate model.

We suspect ...
• the "correct" answers are probably B and D
• whoever wrote the problem wasn't paying attention.

Answer:

D.

Step-by-step explanation:

Intuitively it's a volleyball game reaching its maximum height, then we must discard the 1st option because of its parameter a >0, and whenever a>0 the parabola makes a curve, rather different than in a volleyball game.

Also, considering Vertex of this parabola by (-b/2a, -Δ/4a) given the fact that the question says the maximum height.

Taking

y= height in feet

x= time in second

Function Vertex (-b/2a, -Δ/4a)=(-3, -13)

A: f(x)=2x²+12x+5 False

B: f(x)=-2x²+12x-5 Function Vertex (-b/2a, -Δ/4a) = (3,23) False

C: f(x)=-2x²-12x+5  Function Vertex (-b/2a, -Δ/4a) = (-3,23) False

D: f(x)=-2(x-3)²+13 Function Vertex (-b/2a, -Δ/4a) = (3,13) True

Peter is 2 years older than Winnie. Peter's age is 16 years less than seven times Winnie's age. The equations below model the relationship between Peter's Age (p) and Winnie's age (w):

p=w+2
p=7w-16

Which is a possible correct method to find Peter's and Winnie's ages?

A. Solve w+2 = 7w-16 to find the value of w
B. Solve p+2 =7p-16 to find the value of p
C. Write the points where the graphs of the equations intersect the x axis
D. Write the points where the graphs of the equations intersect the y axis

Answers

Given equations:
P=w+2
p=7w-16
Compare both equations
7w-16=w+2
Add 16 to both sides.
7w=w+18
Subtract w from both sides.
6w=18
Divide both sides by 6.
w=3, which is the age of Winnie.
Now Peter's age=3+2=5 years

Option A is the correct method to find the age of Peter and Winnie.

Answer:

A. Solve w+2 = 7w-16 to find the value of w.

Step-by-step explanation:

Here p represents the age of Peter and w represents the age of Winnie,

Given,

Peter is 2 years older than Winnie.

⇒ p = w + 2 -----(1)

Also, Peter's age is 16 years less than seven times Winnie's age.

⇒ p = 7w - 16 -----(2),

By equating right sides of equation (1) and (2),

We get,

w + 2 = 7w - 16,

Since, this equation is only in the variable w,

Thus, we can find the value of w with help of the above equation,

After putting this value in either of equation (1) or (2),

We can find the value of p.

Hence, option A is correct.

Note : From equation (1) and (2),

w = p - 2 and [tex]w=\frac{p+16}{7}[/tex]

[tex]\implies p-2=\frac{p+16}{7}[/tex]

⇒ Option B is incorrect.

Now, let x represents w and y represents p in the graph,

Then, the solution will be the intersection point of lines y=x+2 and y=7x-16,

Which is shown below,

Options C and D are incorrect.

The following data represent the flight time​ (in minutes) of a random sample of seven flights from one city to another city.
287, 270, 260, 266, 257, 264, 258

Compute the range and sample standard deviation of flight time

Answers

The range is found by subtracting the highest and lowest values:
287-257=30.
To find the standard deviation, we must first find the mean.  That is found by adding together all of the data and then dividing by the number of data points.  The sum of the data is 1862.  Divide this by 7 (the number of data points) and the mean is 266.
Now we subtract each data point from the mean.  We square this number, average these together and find the square root:
287-266=21
270-266=4
260-266=-6
266-266=0

What is the distance between y = -x+2 and y = -x+4?

Answers

Answer:

  √2

Step-by-step explanation:

You want the distance between the lines y = -x +2 and y = -x +4.

Distance to a line

The distance from point (x, y) to line ax +by +c = 0 is given by the formula ...

  [tex]d=\dfrac{|ax+by+c|}{\sqrt{a^2+b^2}}[/tex]

Application

Rewriting the equation of the second line to general form, we have ...

  y = -x +4

  x +y -4 = 0 . . . . . . . a=1, b=1, c=-4

The equation of the first line is written in slope intercept form, so we can identify the y-intercept as (0, 2). Using this point in the formula for the distance to the second line, we have ...

  [tex]d=\dfrac{|1(0)+1(2)-4|}{\sqrt{1^2+1^2}}=\dfrac{|-2|}{\sqrt{2}}=\sqrt{2}[/tex]

The distance between the lines is √2 units.

__

Additional comment

As you can see from the graph, the distance between the lines is the length of the diagonal of a unit square, √2.

A line passes through the point (8, -1) and has a slope of -5/2
Write an equation in slope-intercept form for this line.

Answers

Final answer:

To find the slope-intercept form of a line with a given slope of -5/2 that passes through the point (8, -1), we use the point-slope form and then rearrange to get the final equation: y = (-5/2)x + 19.

Explanation:

To write the equation of a line in slope-intercept form (which is y = mx + b), we need to know the slope (m) of the line and the y-intercept (b). In this case, we are given the slope of the line as -5/2 and a point through which the line passes, which is (8, -1). Using the point-slope form, which is y - y1 = m(x - x1) where (x1, y1) is the given point and m is the slope, we can substitute the given slope and the coordinates of the given point to derive the slope-intercept form.

The equation starts with y - (-1) = (-5/2)(x - 8). Simplifying the equation, we get:

y + 1 = (-5/2)x + (5/2)*8

y = (-5/2)x + 20 - 1

y = (-5/2)x + 19

So, the equation of the line in slope-intercept form is y = (-5/2)x + 19.

Final answer:

To write an equation in slope-intercept form, substitute the given values of the slope and a point on the line into the equation. The equation of the line passing through the point (8, -1) with a slope of -5/2 is y = -5/2x + 19.

Explanation:

To write an equation in slope-intercept form, we need to use the given slope and the coordinates of the point through which the line passes. The slope-intercept form is y = mx + b, where m represents the slope and b represents the y-intercept. We're given that the slope of the line is -5/2, so we can substitute this value for m. We're also given that the line passes through the point (8, -1), so we can substitute these coordinates to find the value of b.

Using the point-slope form of a line, we have y - y1 = m(x - x1). Substituting the given values, we get y - (-1) = -5/2(x - 8). Simplifying, we have y + 1 = -5/2x + 20. Moving the 1 to the other side, we have y = -5/2x + 19. This is the equation of the line in slope-intercept form.

Solve for w.

A.) W= 4k-2b / -5

B.) W= 3k^2- b / -5

C.) W= -3k^2 - b / 5

D.) W= 3k^2 + 2b / -5

Answers

K = (2b-5w)/3k

Cross multiply

K × 3k = 2b - 5w

5w = 2b-3k²

w = (2b-3k²)/5...

The solution for (w) is  W= 4k-2b / -5, corresponding to option A.

To solve the equation [tex]\(k = \frac{2b - 5w}{3k}\)[/tex] for (w), we follow these steps:

1. Isolate the term containing (w):

  Multiply both sides of the equation by (3k) to eliminate the denominator:

[tex]\[3k^2 = 2b - 5w\][/tex]

2. Isolate (w):

  Subtract \(2b\) from both sides of the equation:

[tex]\[3k^2 - 2b = -5w\][/tex]

3. Divide both sides by (-5):

  Divide both sides of the equation by (-5) to isolate (w):

[tex]\[w = \frac{3k^2 - 2b}{-5}\][/tex]

Now, let's summarize the answer:

The solution for (w) is given by option:

He wanted to prove that the power could be transferred to other objects. He grabbed a kite and experimented on a stormy afternoon. Franklin believed that thunder clouds contained electrical charges. His plan was to fly the kite into the clouds so that electricity passed down the wet kite string. With his son, William, as his assistant, he went to work. First, he tied an iron key to the silk kite string. Next, he ran a metal wire from the key into a jar designed to store electrical charges. Once the kite was in the air, he stood in a barn to keep safe and dry. Soon, electrical charges from the clouds passed into the kite. They traveled along the wet string, to the key, down the wire, and into the jar. When Franklin reached his hand toward the key, he received a mild shock.
