1) The equation of the parallel line in Slope Intercept Form is; y = -x - 1

2) The equation of the perpendicular line in Slope Intercept Form is;

y = ³/₂x - 4

How to write equation in Slope Intercept Form?

1) When two lines are parallel, it means their slopes are the same.

Formula for equation in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus, slope of y = -x + 1 is m = -1.

Equation of parallel line is;

(y - (-5))/(x - 4) = -1

y + 5 = -x + 4

y = -x - 1

2) When two lines are perpendicular, it means their slopes are the negative inverse of each other. Thus;

Slope of line = -2/3 and so slope of perpendicular line = 3/2. Thus, equation of new line is;

(y + 1)/(x - 2) = 3/2

2y + 2 = 3x - 6

2y = 3x - 8

y = ³/₂x - 4

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation for table 3 is y=(5/2)x-4.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is y-intercept.

The slope for the tables,

Table 1.

m₁ = (3-1)/(5-2) = 2/3

m₂ = (43-31)/(20-17) = 12/3 = 4

Since the slope is different the relationship is not linear.

Table 2.

m₁ = (13-10)/(2-1) = 3/1

m₂ = (34-29)/(7-6) = 5/1

Since the slope is different the relationship is not linear.

Table 2.

m₁ = (6-1)/(4-2) = 5/2

m₂ = (31-26)/(14-12) = 5/2

Since the slope is the same the relationship is linear.


The equation for table 3 will,

y = (5/2)x + c

1 = (5/2)2 + c

1 = 5 + c

c = -4

Hence, the equation for table 3 is y=(5/2)x-4.

Given the situation, which inequality models the number of additional weeks marie needs to continue saving to afford the home repairs? select the correct answer.

Answers

In the inequality models, the number of additional weeks is 1558+60x≥2158.

Given that the initial savings is $1558, the amount needed is $2158 and additional savings is $60 weekly.

Let the number of weeks be x.

So, she will save 60x in x weeks.

Total savings after x weeks is

Initial saving +60x       .......(1)

According to the question, she needs $1258 for repair.

So, that means the minimum requirement is 2158.

≥2158      ........(2)

Combine equations (1) and (2) and get

Initial savings +60x≥2158

As given that the initial savings is 1558.

Substitute this in above inequality and get

1558+60x≥2158

To find the number of weeks find value of x.

Subtract 1558 from either sides of the inequality.

1558+60x-1558≥2158-1558

60x≥600

Divide both sides with 60 as

60x÷60≥600÷60

x≥10

Hence, the inequality that models the number of additional weeks marie needs to continue saving to afford the home repairs is 1558+60x≥2158 and she needs to save $60 for at least 10 weeks.

Yes

Answers

Answer:

x=8 and y=3 (So, yes!)

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

−x+4y=4;−x+3y=1

Step: Solve −x+4y=4 for x:

−x+4y+−4y=4+−4y(Add -4y to both sides)

−x=−4y+4

-x/-1 = -4y+4/-1 (Divide both sides by -1)

x=4y−4

Step: Substitute 4y−4 for x in −x+3y=1:

−x+3y=1

−(4y−4)+3y=1

−y+4=1(Simplify both sides of the equation)

−y+4+−4=1+−4(Add -4 to both sides)

−y=−3

-y/-1 = -3/-1 (Divide both sides by -1)

y=3

What is the Pythagorean theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.

Given,  A cone with the height of 2√3 and the radius of base is 2 cm.

Since, Surface are of Cone = rlπ + B

Where l= slant height, and B = area of the base

In our case,

r = 2

B = π * r*r = π* 4

for slant height,

Slant makes a perfect right angle triangle with the center line thus,

from Pythagorean theorem,

l² = (2√3)² + 2²

l² = 12 + 4

l = 4 cm

Thus,

Surface area for the Cone = π * 2 *4 + π * 4

Surface area for the Cone = 12π

therefore, Surface Area of the cone 12π cm².

how long does it take to drive 40 miles if you are going 40 mph

Answers

Answer:

1 Hour

Step-by-step explanation:

d = r/t

d = 40/40

d = 1 hour

Step-by-step explanation:

just think : what does 40 mph mean ?

it stands for

40 miles per hour

it means with that speed you will drive 40 miles in 1 hour.

20 miles in 1/2 hour.

80 miles in 2 hours and so on.

you always have to multiply both sides of the ratio with the same factor to keep the ratio itself unchanged.

so, as per the definition, it takes 1 hour to drive 40 miles when going 40 mph.

The cost in dollars of making x items is given by the function C(x)=10x+900 .

Fixed cost =$
c(0)=900

b. What is the cost of making 25 items?



C(25)=$
Number

c. Suppose the maximum cost allowed is $2400 . What are the domain and range of the cost function, C(x) ?

When you enter a number in your answer, do not enter any commas in that number. In other words if you want to enter one thousand, then type in 1000 and not 1,000. It's not possible to understand what the interval (1,000,2,000) means, so you should write that as (1000,2000).

Answers

For the given cost equation we have:

a) Fixed cost is $900.

b) For making 25 items the cost is $1150.

c) D: x ∈ [0, 150]

   R: c ∈ [900, 2400]

Working with the cost equation.

Here we know that the cost equation is:

c(x) = 10*x + 900.

First, we want to get the fixed cost, it is given by evaluating the function in x = 0.

c(0) = 10*0 + 900 = 900

The fixed cost is 900.

b) Now we want to get the cost for making 25 items, to get this, we just evaluate in x = 25.

c(25) = 10*25 + 900 = 250 + 900 = 1150

c) Now, if the maximum cost is 2400, then the maximum number of items that we can make is x₀, such that:

c( x₀) = 2400 = 10*x₀ + 900

Solving for x₀ we get:

x₀ = (2400 - 900)/10 = 150

Now we want to get the range and domain.

We know that we can make between 0 and 150 items, so the domain is:

D: x ∈ [0, 150]

For the range, we know that the fixed cost for 0 items is 900, and the maximum cost is 2400, then the range is:

R: c ∈ [900, 2400]

The radioactive isotope of phosphorus P-32 is used as a tracer in the liver. If 3.5 mg
is left in a sample after 288 hrs then how much P-32 was administered initially? [The
half-life of P-32 is 14.3 days.]
6.26 mg
4.17 mg
1.96 mg
7 mg

Answers

6.26 mg! that’s the answer!! hope it helps you.

The radioactive isotope of phosphorus P-32 is used as a tracer in the liver. If 3.5 mg is left in a sample after 288 hrs then the initial amount of P-32 administered was 7 mg.

What is radioactive isotope?

A radioactive isotope is a form of an element that has an unstable nucleus and undergoes radioactive decay, emitting radiation in the form of particles and/or energy.

These isotopes can be used for various purposes in medicine, industry, and research.

We can use the radioactive decay formula to solve this problem:

N = N0 * (1/2)^(t/T)

where:

- N is the final amount of P-32 remaining after 288 hours (3.5 mg)

- N0 is the initial amount of P-32

- t is the time elapsed (288 hours)

- T is the half-life of P-32 (14.3 days converted to hours is approximately 343.2 hours)

Substituting the given values into the formula, we get:

3.5 mg = N0 * (1/2)^(288/343.2)

Simplifying and solving for N0:

N0 = 3.5 mg / (1/2)^(288/343.2) = 7 mg

Therefore, the initial amount of P-32 administered was 7 mg.

The little blind children at the Perkins Institution had sent it and Laura Bridgman had dressed it; but I did not know this until afterward. When I had played with it a little while, Miss Sullivan slowly spelled into my hand the word "d-o-l-l." I was at once interested in this finger play and tried to imitate it. When I finally succeeded in making the letters correctly I was flushed with childish pleasure and pride. Running downstairs to my mother I held up my hand and made the letters for doll. I did not know that I was spelling a word or even that words existed; I was simply making my fingers go in monkey-like imitation. In the days that followed I learned to spell in this uncomprehending way a great many words, among them pin, hat, cup and a few verbs like sit, stand and walk. But my teacher had been with me several weeks before I understood that everything has a name. I left the well-house eager to learn. Everything had a name, and each name gave birth to a new thought. As we returned to the house every object which I touched seemed to quiver with life. That was because I saw everything with the strange, new sight that had come to me.Which of the following best summarizes the excerpt?Helen's teacher taught her to finger spell doll so she knew how to tell her teacher what toy she wanted to play with.Helen was excited to learn that everything had a name so that she could talk with her teacher.Helen liked to touch all the objects in the house so she knew which ones she wanted to play with.Helen's teacher taught her all objects have a name opening the world of language.
