A line passes through the points (-1, 4) and (3, -8). A second line passes through
(-1,8) and (2, 11).
A) Write the equation of each line. Show all work.

Answers

Answer 1

Answer:

y = -3x + 1,  y = x + 9

Step-by-step explanation:

An equation consists of a slope and the y-intercept. To find the slope, you need to plug the values into the slope formula.

y2 - y1/ x2 - x1

= -8 - 4/ 3 - (-1)

= -12/ 4

= -3

The slope of the first line is -3.

To find the y-intercept, you need to plug in either one of the coordinates into the equation, y = -3x + b

-8 = -3(3) + b

-8 = -9 + b

1 = b

The equation, for the first one, is y = -3x + 1  

Line 2:

11 - 8/ 2 - (-1)

= 1

y = 1x + b

11 = 1(2) + b

11 = 2 + b

9 = b

y = x + 9

Answer:

The second one

Step-by-step explanation:

A visual for law of sines can be found below

Sin (an angles) over its opposite side length is equal to sin ( a different angle) over its opposite side length

In the given triangle we are given side length BC and side length AB

we are also given AB's opposite angle  (40)

And we need to find side length BC's opposite angle (A)

That being said we are given enough information to set up an equation using the law of sines

Remember angle A's opposite side length is 16 and the angle that has a measure of 40 degrees' opposite side length is 12

so the equation would look like...

[tex]\frac{sin(40)}{12} =\frac{sin(A)}{16}[/tex]

A fair coin is flipped twice. H is recorded for heads and T for tails after each flip. The notation for conditional probability is ​P(H on 2nd flip|H on 1st flip)​. Which notation is the probability of the two events being not independent?

Answers

Answer:

The Notation for each event Not been independent = P( HT ) or P( TH )

Step-by-step explanation:

when A fair coin flipped ; P( H ) = 0.5 and P( T ) = 0.5

Hence when it is flipped twice the possible outcome = 4

= HH , HT , TT, TH

Since Notation for conditional probability = P ( HH )  this shows that each flip is independent

The Notation for each event Not been independent = P( HT ) or P( TH )

Answer: P(H on 2nd flip|H on 1st flip)=P(H on 2nd flip)

Answer: 1539π cubic inches.

Step-by-step explanation:

In the figure, we have a hemisphere joined with a cylinder of the same diameter 18 inches.

Radius = 9 inches   (half of diamter)

Volume of hemisphere = [tex]\dfrac23 \pi r^3[/tex]

Volume of cylinder = [tex]\pi r^2 h[/tex], where r= radius h= height

Volume of hemisphere= [tex]\dfrac{2}{3}\pi (9)^3=486\pi in.^3[/tex]

Volume of cylinder = [tex]\pi (9)^2 (13)=1053\pi\ in.^3[/tex]

Combined volume = 486π+1053π=1539π cubic inches.

Hence, the volume of the solid = 1539π cubic inches.

Maya tutors english. for each hour that she tutors, she earns 40 dollars.Her earnings, E (in dollars),after tutoring for h hours is given by the following.How much does maya earn if she tutors for 5 hours?

Answers

Answer:

Amount earn by Maya for teaching English in 5 hour = $200

Step-by-step explanation:

Given:

Amount Maya earn in 1 hour for teaching English = $40

Find:

Amount earn by Maya for teaching English in 5 hour

Computation:

Assume;

Per hour earning = E

Number of total hour = h

Total earning = Per hour earning x Number of total hour

Total earning = (E)(h).

So,

Amount earn by Maya for teaching English in 5 hour = 5 x 40

Amount earn by Maya for teaching English in 5 hour = $200

2. $1000/65hrs = $15.38 per hour

3. Assuming that you get time and a half for OT.

= $1125 + $750

Amelia has 3 gallons of paint .Mason have 10 quarts .How many more pints of paint does AMELIA have then mason.

Answers

Answer:

4 Pints

Step-by-step explanation:

According to the scenario, calculations are as follows,

As we know, 1 gallon = 8 Pints

1 Quarts = 2 Pints

So, Amelia = 3 Gallons = 3 × 8 Pints = 24 Pints

Mason = 10 quarts = 10 × 2 Pints = 20 Pints

So, Number of more pints Amelia has = Amelia number of pints - Mason number of pints

= 24 pints - 20 pints

= 4 Pints

Find the total cost, to the nearest cent, for a sweater that cost $22.95 with an additional 5.5% tax sale

Answers

Answer: $24.2

Step-by-step explanation:

The total cost will be gotten by adding the cost of the sweater and the tax. This will be:

Cost of sweater = $22.95

Tax = 5.5% × $22.95 = 0.055 × $22.95 = $1.26225

Total cost of the sweater = $22.95 + $1.26225 = $24.21225

= $24.2 to nearest cent

Answer:

5.5% of 22.95 is about 1.26

22.95 + 1.26 = 24.21

$24.21
