The Graph Of A Function In The Form F(x) A(x - H)2 +k Is Shown. Use The Graph To Find An Equation For

Answers

Answer 1
O.K.

(h; k) are the coordinates of the vertex.

On the graph are (3; 4), therefore we have:

[tex]f(x)=a(x-3)^2+4[/tex]

We have the x-intercept (1; 0) → x = 1; y = 0.
Substitute them in the equation:

[tex]0=a(1-3)^2+4\\\\0=a(-2)^2+4\\\\4a+4=0\ \ \ |-4\\\\4a=-4\ \ \ \ |:4\\\\a=-1[/tex]

so. We have the answer:

[tex]\boxed{f(x)=-(x-3)^2+4}[/tex]

Devon exercised the same amount of time each day for 5 days last week. e His exercise included walking and swimming. e Each day he exercised, he walked for 10 minutes . He exercised for a total of 225 minutes last week. What is the number of minutes Devon swam each of the 5.days last week?

Answers

I think that Devon swam at least 35 minutes each day for 5 days because if he exercised 225 minutes and each day he walked for 10 minutes then if you divide 225 by 5 you get 45 so every day he exercised 45 minutes and since he walked for 10 minutes you subtract 10 from 45 which gives you 35 so he swam for 35 minutes.

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.

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
257-266=-9

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.

B. 216π m³

C. 972π m³

D. 1296π m³

Answers

we are given

radius=r=12m

height=h=9m

now, we can use formula of volume of cylinder

[tex] V=\pi r^2 h [/tex]

now, we can plug values

and we get

[tex] V=\pi (12)^2 *9 [/tex]

we get

[tex] V=1296 \pi m^3 [/tex]

so, the exact volume of the cylinder is [tex] 1296 \pi m^3 [/tex]..........Answer

Answer:

(D)

Step-by-step explanation:

It is given that a cylinder has a radius of 12 m and a height of 9 m.  Then,

Volume of the cylinder is given as:

[tex]V={\pi}r^{2}h[/tex]

⇒[tex]V={\pi}(12)^2(9)[/tex]

⇒[tex]V={\pi}(144)(9)[/tex]

⇒[tex]V=1296{\pi}m^3[/tex]

Therefore, the volume of the cylinder is [tex]1296{\pi}m^3[/tex].

Thus, Option D is correct.

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:

Bank payments are okay as well. You can check if your bank offers online bill payment services. If they do, you can use and process online. Advantages are it's easy to process and won't take long.


However, Disadvantages for both methods are:

Another thing is if there were technical errors they could deduct twice of the amount that you are not aware of.
