1: y=-5/2x-8

2: y=5x

3: y=3x-8

**Answer:**

1. 2/5

2. -1/5

3. -1/3

**Step-by-step explanation:**

the parpendicular slope is found by taking the original slope and finding the opposite reciprocal. so just flip the slope and make it the opposite sign

-5/2 ---> 2/5

+5/1 ---> -1/5

+3/1 ---> -1/3

Answer:

1. 2/5

2. -1/5

3. -1/3

Explanation:

There are two key concepts that we have to understand in order to answer this question:

1) The given equations are organized in slope-intercept form: y=mx+b. Here’s what the variables mean:

Y= the y coordinate

M=the slope

X= the coordinate

B= the y intercept

From the given equations we can now identify the slopes as -5/2, 5 and 3.

2) Perpendicular lines have slopes that are NEGATIVE RECIPROCALS of each other.

Example: Line A has the slope 8. A line that is perpendicular to line A would have a slope of -1/8.

Example #2: Line B has the slope -2/3. A line that is perpendicular to line B would have a slope of 3/2 (two negatives make a positive).

Now that we understand these two concepts, we need to look at the slopes of the given lines and determine their negative reciprocals to find the slopes of their perpendicular lines.

1. y=-5/2x-8

We can see that -5/2 is in the place of “m” in y=mx+b. The negative reciprocal of -5/2 is 2/5, so therefore, the slope of the line perpendicular to y=-5/2x-8 is 2/5.

2. y=5x

There is no “b” value in this equation, but we can still identify 5 as “m”. The negative reciprocal of 5 is -1/5, so therefore, the slope of the line perpendicular to y=5c is -1/5.

3. y=3x-8

The negative reciprocal of 3 is -1/3, so therefore, the slope of the line perpendicular to line y=3x-8 is -1/3.

Write the slope-intercept form of the equation for

each graph described.

Line passing through (-2,-8) and (9,-8)

**Answer:**

y=-8

**Step-by-step explanation:**

First find the slope which is rise over run which equals (y2-y1)/(x2-x1)

(-8-(-8))/(9-(-2))

(-8+8)/(9+2)

0/11

slope = 0

Now you have the slope of 0. You can plug in one of the given point (x,y) to find b

-8=0(9)+b

-8=b

Combine everything

y=0x-8

y=-8

PLZZ ANSWER THE QUESTION

**Answer:**

c

**Step-by-step explanation:**

y = mx + b

”m” is the slope, so the slope is -2

”b” is the y - intercept, so the y - intercept is (0 , 1)

Grace is measured for her annual check up. She is 28 1/5 inches tall. Last year she was 25 3/5 inches tall. How much did she grow in one year?

**Answer:**

2 3/5 inches in a year

**Step-by-step explanation:**

28 1/5 - 25 3/5 = 141/5 - 128/5 = 13/5 = 10/5 + 3/5 = 2 + 3/5 = 2 3/5

If a, b and c are positive integers for which (a,b,c) is the only

ordered triple such that 6a +9b + 20c = 61, then what is

a+b+c?

If *a*, *b*, and *c* are all positive integers and 6*a* + 9*b* + 20*c* = 61, then right away you know *c* < 3, because if *c* = 3, then 20*c* = 60, and there are no solutions for *a* and *b*.

So consider two cases:

• If *c* = 2, then we're left with 6*a* + 9*b* = 21.

• If *c* = 1, then 6*a* + 9*b* = 41.

We have gcd(6, 9) = 3, but 41 is prime and 3 does not divide 41. So we throw out the second case.

This leaves us with 6*a* + 9*b* = 21. Notice that if *a* = *b* = 1, then 6*a* + 9*b* = 15. Add 6 to both sides to get 21. So *a* = 2, *b* = 1, and *c* = 2, and hence *a* + *b* + *c* = **5**.

g A circle is a special case of an ellipse. Explain how a circle is different from other ellipses.

**Answer:**

Main difference between circle & ellipse

**Step-by-step explanation:**

Circle is a line forming a close loop, all points on the loop line are at equal distance from the centre, that distance is called Radius. Eg : Wheel

Ellipse is also a close loop line, such that distance of locus of all points on the plane to two fixed points (foci) always sum up to same constant. ** **Eg : Orbits of planets

**Cricle **is the round **shape entity** in which it contains only radius and **double **of radius is diameter Thus below explanation is the answer to the Question

Research shows that many banks are unwittingly training their online customers to take risks with their passwords and other sensitive account information, leaving them more vulnerable to fraud (Yahoo, July 23, 2008). Even web-savvy surfers could find themselves the victims of identity theft because they have been conditioned to ignore potential signs about whether the banking site they are visiting is real or a bogus site served up by hackers. Researchers at the University of Michigan found design flaws in 78% of the 214 U.S. financial institution websites they studied.

Required:

Is the sample evidence sufficient to conclude that more than three out of four financial institutions that offer online banking facilities are prone to fraud? Use a 5% significance level for the test.

Answer:

Decision rule

Fail to reject the null hypothesis

Conclusion

The sample evidence is not sufficient to conclude that more than three out of four financial institutions that offer online banking facilities are prone to fraud.

Step-by-step explanation:

From the question we are told that

The sample size is n = 214

The sample proportion is p = 0.78

The level of significance is [tex]\alpha = 0.05[/tex]

Generally the population proportion is mathematically represented as

[tex]p = \frac{3}{4} =0.75[/tex] (gotten from the statement ''three out of four'' in the question)

The null hypothesis is [tex]H_o : p = 0.75[/tex]

The alternative hypothesis [tex]H_a : p > 0.75[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\^{p} - p}{ \sqrt{\frac{p(1-p)}{n} } }[/tex]

=> [tex]z = \frac{0.78- 0.75}{ \sqrt{\frac{ 0.75(1-0.75)}{214} } }[/tex]

=> [tex]z = 1.01[/tex]

Generally the p-value is mathematically represented as

[tex]p-value = P(Z > z )[/tex]

=> [tex]p-value = P(Z > 1.01 )[/tex]

From the z-table

[tex]P(Z > 1.01 ) = 0.15625[/tex]

So

[tex]p-value = 0.15625 [/tex]

From the obtained values we see that [tex]p-value > \alpha[/tex] hence we fail to reject the null hypothesis

Therefore we can conclude that the sample evidence is not sufficient to conclude that more than three out of four financial institutions that offer online banking facilities are prone to fraud.

Jeffrey thinks that the largest place value that 8.21 and 19.5 have in common is the tens place Austin thinks that the largest place value they have in common is the ones place

**Answer:**

Austin is correct.

**Step-by-step explanation:**

19.5 has a tens, ones, and tenths place. 8.21 has a ones, tenths, and hundredths place.

**Answer:**

Neither are correct.

**Step-by-step explanation:**

8.21:

Tens Place - 0

Ones Place - 8

Tenths Place - 2

Hundredths Place - 1

19.5:

Tens Place - 1

Ones Place - 9

Tenths Place - 5

Hundredths Place - 0

None of the places are in common, so neither Jeffery nor Austin is correct.

An airplane maintaining a constant airspeed takes as long to travel 925 mi with wind as it does to travel 775 mi against the wind. If the wind is blowing at 15 mph, what is the rate of the plane in still air

9514 1404 393

**Answer:**

170 mph

**Step-by-step explanation:**

The speed of the airplane can be represented by s. The travel time will be ...

time = distance/speed

925/(s +15) = 775/(s -15)

925(s -15) = 775(s +15)

150s = 25500 . . . . . . . . . add 13875-775s

s = 170

**The rate of the plane in still air is 170 mph**.

A large hamburger (e.g., Whopper®) sandwich contains 628 kcal and 36 grams of fat. Approximately what percentage of the total energy is contributed by fat?

Answer:

Step-by-step explanation:

Total energy of the sandwich = 628kcal

Mass of fat contained = 36grams

Convert gram to kcal

1gram = 9kcal

36 grams = x

x = 36×9

x = 324kcal

Hence the fat contains 324kcal

%fat contained = fat(in kcal)/total calorie × 100%

%fat contained = 324/628 × 100%

%fat contained = 1/2 × 100%

%fat contained = 50%

Hence approximately 50% of the total energy is contributed by fat.

does the surface in contact with ground affect the going motion of the car ?why?

**Answer:**

Yes, it does. The ground is bumpy and it creates friction acting against the car's motion.

(you can include my example too depending on what your teacher is looking for)

**Step-by-step explanation:**

This is a fun one! Think about a ball rolling on a smooth surface, now on a bumpy sandpapery one. Which one do you think is faster? The smooth surface! This is because of this friction of the sandpaper which slows down the ball. On the other hand, the smooth one has very little friction. The same applies to cars.
