Find the equation of the line: which passes through (1,-7) and is perpendicular to (-4,6) and (5,-3)

Answers

Answer 1

Answer:

-9 6 that is because the line has to be perpenducular to the other line

Answer 2

Step-by-step explanation:

Slope of line between points (-4, 6) and (5, -3)

=> Rise / Run

=> [6 - (-3)] / [(-4) - 5]

= 9 / (-9)

= -1.

Thus slope of perpendicular line

= -1 / (-1) = 1.

We have y = x + c.

When x = 1, y = -7.

=> (-7) = (1) + c, c = -8.

Hence y = x - 8.

32 feet long and 6 yards wide what is the perimeter in feet

Answers

Answer:

100

Step-by-step explanation:

1 yard = 3 feet

6 yards = 18 feet

(18*2)+(32*2)

36+64

100

Answer:  The perimeter is a 100 feet.

Step-by-step explanation:

If it is 32 feet long and 6 yards wide then I am thinking that the shape will be a rectangle.

To find the shape of a rectangle, you can use the formula,  P = 2l+2w  were P is the perimeter, l is the length, and w is the width.  

But first since feet and yards are different measurements, and the question is asking for the perimeter in feet, then you will first have to convert 6 yards to feet.  

6 yards = 18 feet  

This means that the sides  will be 32 feet long and 18 feet wide.

Now using the formula, input 32 for L and 18 for W and solve for P the perimeter.

 P  = 2(32) + 2(18)

P = 64+ 36

P = 100

Enter numbers in the boxes to represent the second term as an ordered pair.

(
,
)

Answers

Answer:

The ordered pair to represent the second term as an ordered pair is:

(2, 9)

Step-by-step explanation:

Background knowledge about the sequence function

A sequence is defined as the function whose domain is the set of natural numbers (counting numbers).

1,        2,        3,       4,     ....        n,   ....  

a₁,       a₂,      a₃,      a₄,    ....       aₙ,   ....

Here,

1 gets mapped onto a₁,

2 gets mapped onto a₂, and so on

The numbers a₁,       a₂,      a₃,      a₄,    ....       aₙ,   .... are the terms of the sequence.

The number aₙ is the nth term of a sequence.

And the sequence function is denoted by {aₙ}.

Given the sequence

3, 9, 15, 21, ...

Here,

a₁ = 3 is the first term

a₂ = 9 is the second term

Thus, the ordered pair to represent the second term as an ordered pair is:

24. Paul's car holds a maximum of 19 gallons of gas. About how many
liters of gas does Paul need to fill his gas tank?
no

Answers

Answer:

71.915

Step-by-step explanation:

3.785= how many liters that are in a gallon X 19= gallons of gas needed to fill the tank

The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank.

What is unit conversion?

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

Given that,

The amount of fuel Paul's car holds = 19 gallons.

We know that,

1 gallon = 3.78541 liter

Multiply both sides by 19

19 gallon = 71.92 liter.

Hence "The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank".

Decide whether or not the relation is a function.

[(0,1), (-5,4), (0,2), (5,-4)]

Answers

Answer:

The relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

Given the relation

{(0,1), (-5,4), (0,2), (5,-4)}

From the given relation is clear that the input value x = 0 is repeated twice.

In other words, the input value x = 0 is duplicated.

As we have already mentioned that we can not have duplicated inputs as there should be only 1 output for each input.

Therefore, the relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.

the area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. find a if it is known that parabola opens upward

Answers

Answer

1/4 × 6 × (5a) = 12

15a=12

a= 4/5

Step-by-step explanation:

The area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. The constant (a) of the function is 4.

How to find the if the parabola is open?

The triangle formed by the parabola has a base equal to the distance between the points where the graph touches the x-axis and height (h) is the point where the graph touches the y-axis.

The points on the x-axis are the roots of the quadratic equation:

a(x-3)(x+2)=0

(x-3)(x+2)=0

x - 3 = 0

x = 3

or

x + 2 = 0

x = -2

So, the base is the distance between (-2,0) and (3,0).

Since they are in the same coordinate, the distance here;

b = 3 - (-2)

b = 5

The area of the triangle is 10. So

5a = 10 x 2

a = 4

The constant (a) of the function y = a(x-3)(x+2) is 4.

Who will charge more to walk a dog for 2.5 hours, Taylor or Lucy? How much more?


Who?:


How much more?:

Answers

Answer:

Taylor will charge more by $15

Step-by-step explanation:

Given

Taylor

First Hour = $15

Hourly Rate = $10

Lucy:

[tex]f(x) = \left \{ {{20x,\ 0 \le \ x \ \le 2} \atop {10x, x>2}} \right.[/tex]

For a dog walk of 2.5 hours.

Taylor's charges is:

[tex]Charges = First\ Hour + Hourly\ Rate * 2.5[/tex]

[tex]Charges = \$15 + \$10 * 2.5[/tex]

[tex]Charges = \$15 + \$25[/tex]

[tex]Charges = \$40[/tex]

Lucy's charges is:

Here, we consider

[tex]f(x) = 10x[/tex] Because [tex]x > 2[/tex]

i.e 2.5 > 2

So, Lucy's charges is:

[tex]Charges = 10 * \$2.5[/tex]

[tex]Charges = \$25[/tex]

By comparison;

Taylor will charge more by $15

The difference is calculated by:

[tex]Difference = \$40 - \$25[/tex]
