a line includes the points (10,-5) and (-10,-1). What is the equation in slope intercept form?

Answer:

x = 5

Step-by-step explanation:

To solve this, we just have to the multiplication and do the simplification (adding up the similar terms) afterwards:

3(x+1)=7(x-2)-3 becomes...

3x + 3 = 7x - 14 - 3

3x + 3 = 7x -17

Then we move all x's on one side and all plain numbers on the other side, we'll move the x's to the right since there's a bigger value there, and will move the plain numbers on the left side, by subtracting 3x and by adding 17 on both sides

3x + 3 - 3x + 17 = 7x -17 + 17 - 3x

20 = 4x

If we isolate x alone we have:

20/4 = x or x = 5

Employers frequently offer full-time employees benefits such as health insurance, retirement plans like 401(k)s, life insurance, paid vacation, and tuition reimbursement, in addition to legally required contributions to Social Security and unemployment insurance.

Employers often provide a range of benefits to their full-time employees beyond the usual salary. Common benefits include:

Health insurance, which helps cover medical expenses that are not covered by public health care plans.

Retirement plans, such as a 401(k) plan where employees can have a portion of their salary deducted and invested for retirement, often with some form of employer match.

Life insurance, offering financial security to an employee's beneficiaries in the event of their passing.

Paid vacation, allowing employees to have paid time off from work.

Tuition reimbursement programs, where employers provide financial support to employees who pursue further education.

These benefits are crucial as they provide a sense of security and support employees’ work-life balance, health and welfare, and professional development.

In addition to these, employers are required by law to make contributions towards legally required benefits such as Social Security, unemployment, and worker's compensation insurance. Some employers may offer additional perks like telecommuting options or employee assistance programs. However, benefits like free gasoline, rent, or sabbaticals are less common and tend to be specific to certain companies or industries.

The probability of drawing the coin labeled '1' from a bag containing coins labeled '1', '2', and '3' is 1/3, or roughly 0.333. This represents a 33.3% chance.

The question is asking you to calculate the probability of drawing the coin labeled '1' in one draw from a bag of three coins, each labeled '1', '2', or '3'. In probability, we define an event's likelihood as the number of ways that event can occur divided by the total number of possible outcomes.

Here, the event we're interested in is picking the coin labeled '1'. Since there is only one coin labeled '1', there is just one way this event can occur. The total number of possible outcomes is defined by the number of coins in the bag, which is 3 – the coins labeled '1', '2', and '3'.

Therefore, the probability of drawing the coin labeled '1' is calculated as 1/3, or roughly 0.333 when rounded to three decimal places. That means there is approximately a 33.3% chance that the coin labeled '1' will be the next drawn from the bag.

Answer:

13. Option 1

14. Option 2 : 1/4

Step-by-step explanation:

13. First option is correct.

If two marbles are drawn from a bag without replacement then the second event will depend upon the first event i.e. the occurrence of first event will affect the occurrence of second event.

14. If two coins are tossed, the outcomes are

S = {HH, HT, TH, TT}

There is only one outcome that favors the given scenario i.e. first coin showing heads and second showing tails.

So, probability of showing heads first and then second showing tails = 1/4

So second option is correct..

Answer:

To ship a 2 pound package , the company will charge $10 and to ship a 3.5 pound package , the company will charge $20

Step-by-step explanation:

This question is on interpreting the information on the graph

In the first option, a 2 pound package lies on the second part of the charge line that charges $10. This value is similar to that charged for a package with 1.5 pounds too because it lies on same charge line.

In the second option, a package with 3.5 pounds will lie on the fourth part of the charge line that indicates $20. This value is similar to that charged a package with 4 pounds too because it lies on the same charge line.

From the graph, a parcel that weighs;

0 to 1 pound will be charged=$5

 1.5 to 2 pounds will be charged=$10

  2.5 to 3 pounds will be charged=$15

   3.5 to 4 pounds will be charged=$20

Step-by-step explanation:

we know that

The equation of the given parabola is

[tex](y-k)=a(x-h)^{2}[/tex]

we have

the vertex is the point (5,-4)

substitute

[tex](y+4)=a(x-5)^{2}[/tex]

The y-intercept is the point (0,96)

substitute and solve for a

[tex](96+4)=a(0-5)^{2}[/tex]

The paddle wheel takes approximately 967 seconds to complete 100 full revolutions.

To calculate the time it takes for the paddle wheel to complete 100 full revolutions, we need to determine the distance traveled by the fins and divide it by their speed. The diameter of the paddle wheel is given as 4 feet, so the radius is half the diameter, or 2 feet. The distance traveled by one fin along the outer edge is equal to the circumference of a circle, which is 2π times the radius. In this case, the distance is 2π * 2 feet, or approximately 12.57 feet.

Since we want to find the time it takes for 100 full revolutions, we need to multiply the distance traveled by one fin by 100. So the total distance is 12.57 feet * 100, which equals 1257 feet.

Now we can divide the total distance by the speed of the fins to find the time it takes. The speed is given as 1.3 feet per second, so the time is 1257 feet divided by 1.3 feet per second, which is approximately 967 seconds. Rounding to the nearest second, it takes the paddle wheel approximately 967 seconds to complete 100 full revolutions.

The paddle wheel takes approximately 392 seconds to complete 100 full revolutions.

To find the time it takes for the paddle wheel to complete 100 full revolutions, we need to calculate the circumference of the wheel and divide it by the speed at the outer edge.

The circumference of the wheel is the diameter (4 feet) times π. So, the circumference is 4π feet.

Dividing the circumference by the speed of the fins (1.3 feet per second) gives us the time it takes for one revolution. To find the time for 100 revolutions, we multiply this time by 100 and round to the nearest second.

Therefore, the paddle wheel takes approximately 392 seconds to complete 100 full revolutions.

Step-by-step explanation: In mathematics and especially when gathering data, you will gather the most accurate results with a larger portion. The larger portion will ensure a more accurate reading.

Answer:

1510 vehicles

Step-by-step explanation:

First you need to determine how many feet cars and trucks occupy.

In 5 miles:

Cars fill up 80%     = 0.80 x 5 miles = 4 miles

Trucks fill up 20%  = 0.20 x 5 miles = 1 mile

Because we know the lengths and distances of the cars and trucks in feet, let's convert the miles they cover into feet.

Cars = 4 miles x 5280 ft/mile = 21,120 ft

Trucks = 1 mile x 5280 ft/mile =  5280 ft

So how many cars would there be if they covered at least 21,120 ft?

Considering that there is 3 ft between each car and a car has a length of 13.5 ft, a single car will cover 16.5 ft.

To see how many cars then fit in 21,120 ft, just divide it by the distance one car covers.

[tex]\dfrac{21,120ft}{16.5 ft/car} = 1,280 cars[/tex]

So how many trucks would there be if they covered at least 5,280 ft?

A truck is 20 ft long and again there is a space of 3 ft in between. So we add that up to see how many feet a single truck needs.

20 ft + 3 ft = 23 ft

We then take that total and divide the feet covered by trucks.

[tex]\dfrac{5,280ft}{23ft/truck}= 229.57 trucks[/tex]

Since we cannot have half a truck, we round that off to the nearest whole number which will be 230 trucks.

So we add the number of trucks and cars to get the number of vehicles in total:

1280 + 230 = 1,510 vehicles

Altitude is how high or low you are in relation to sea level, while temperature is how hot or cold it is. Altitude often effects the temperature. As high altitude places are usually get cold.

the ones digit is 5, and the tens digit is 5 - 2, which is 3. So the 2-digit number is 35.

The question requires us to find a 2-digit number where the tens digit is two less than the ones digit and the sum of the digits is 8. To figure this out, let's call the ones digit 'x'. Since the tens digit is two less than the ones digit, the tens digit would be 'x - 2'. The sum of these two digits equals 8, so we can write the equation:

x + (x - 2) = 8

Solving for x gives us:

2x - 2 = 8

2x = 8 + 2

2x = 10

x = 10 / 2

x = 5

Therefore, the ones digit is 5, and the tens digit is 5 - 2, which is 3. So the 2-digit number is 35.

Answer:

After how many seconds does it explode? 4 sec

At what height does it explode? 256ft

Step-by-step explanation:

The question simply asks us to find the vertex of the parabola mentioned.

Given equation : h = -16t² + 128t

Lets break this down. The equation is in its standard form : ax² + bx + c

Hence,

a = -16

b = 128

c = 0

Find the vertex when a standard form is given:

( -b/2a , f(-b/2a) )

(-128/-32, f( -128/-32 ))

(4,f( 4 ))

f(4) = -16(4)² + 128(4)

f(4) = -256 + 512

f(4) = 256

Vertex = (4,256)

After how many seconds does it explode? 4 sec

At what height does it explode? 256ft

Step-by-step explanation:

If a ≤ b ≤ c is the length of the sides, then a + b > c.

(a)

We have a = 3cm, b = 4cm, c = 6cm.

Check:

a + b = 3cm + 4cm = 7cm

c = 6cm

7cm > 6cm → a + b > c   CORRECT :)

YES. It's possible.

(b)

We have a = 1cm, b = 3cm, c = 4cm

Check:

a + b = 1cm + 3cm = 4cm

c = 4cm

4cm = 4cm → a + b = c

NO. It's impossible.

Answer:

60 degrees

Step-by-step explanation:

Since all sides of the triangle are congruent and the angles of a triangle add to 180 degrees, divide 180 by 3 sides and you get 60 degrees.

Answer:

60°

Step-by-step explanation:

Since the sides have all got the "equal" sign, all the angles must be the same.

Angles in a triangle add up to 180°.

From this, we can set up an equation ⇔ y + y + y = 180°

⇒ y + y + y = 180°

( Simplify )

⇒ 3 y = 180°

( Divide both sides by 3 to isolate y )

y = 60°

Like $45.95 I think I’m sorry if you get it. Wrong

The question is based on exponential growth, the worker will be earning an hourly wage of $10.00 after approximately 5.9 years of receiving a 4% annual raise.

The subject of this problem is exponential growth, which is based on the formula y = a(1 + r)^t, where a is the initial amount, r is the rate of growth (expressed as a decimal), and t is the time period. In this case, your initial wage (a) is $7.95 per hour and the rate of growth (r) is 4% or 0.04. The future wage (y) is $10.00 per hour. So, the equation becomes:
10 = 7.95 * (1.04 ^t).
To solve for 't', you first divide both sides by 7.95 to isolate (1.04 ^t) on one side, resulting in 1.26 = (1.04 ^t).
You then take the natural logarithm (log base e, also represented as 'ln') of both sides of the equation to eliminate the exponential, resulting in ln(1.26) = t * ln(1.04).
Finally, you divide both sides by ln(1.04) to solve for 't', resulting in an approximate value of 't' as 5.9 years.
Therefore, the worker will be earning $10.00 per hour approximately after 5.9 years.
