what is the slope of the line that passes through the points (2,1) and (17,-17)​

Answers

hi

You have two points     A ( X;Y)  and B ( X ; Y)

slope is   :    ( Yb -Ya)   / (Xb -Xa )

A(2 ; 1)  and  B (17 ; - 17)  

so   :  (-17 - 1 )  / (17 -2) =  -18/ 15 =  - 6*3 / 5*3 =  -6/5

A young couple purchases their first new home in 2011 for​ $95,000. They sell it to move into a bigger home in 2018 for​ $105,000. First, we will develop an exponential model for the value of the home. The model will have the form

Answers

Given:

The value of home in 2011 is $95,000.

The value of home in 2018 is $105,000.

To find:

The exponential model for the value of the home.

Solution:

The general exponential model is

[tex]y=ab^x[/tex]       ...(i)

where, a is initial value and b is growth factor.

Let 2011 is initial year and x be the number of years after 2011.

So, initial value of home is 95,000, i.e., a=95,000.

Put a=95000 in (i).

[tex]y=95000b^x[/tex]       ...(ii)

The value of home in 2018 is $105,000. It means the value of y is 105000 at x=7.

[tex]105000=95000b^7[/tex]

[tex]\dfrac{105000}{95000}=b^7[/tex]

[tex]\dfrac{21}{19}=b^7[/tex]

Taking 7th root on both sides, we get

[tex]\left(\dfrac{21}{19}\right)^{\frac{1}{7}}=b[/tex]

Put [tex]b=\left(\dfrac{21}{19}\right)^{\frac{1}{7}}[/tex] in (ii).

[tex]y=95000\left(\left(\dfrac{21}{19}\right)^{\frac{1}{7}}\right)^x[/tex]

[tex]y=95000\left(\dfrac{21}{19}\right)^{\frac{x}{7}}[/tex]

Therefore, the required exponential model for the value of home is [tex]y=95000\left(\dfrac{21}{19}\right)^{\frac{x}{7}}[/tex], where x is the number of years after 2011.

A flagpole 12 meters tall casts a 24-meter shadow. Nearby, luke stands and is 4 meters tall. Determine the length of luka's shadow. Include all labels.

Answers

Answer:

8 meters

Step-by-step explanation:

This is a question that deals with Proportion

Height of flagpole/Shadow of flagpole = Height of Luke/Shadow of Luke

Length of the shadow of Luke = x

= 12/24 = 4/x

We cross Multiply

12 × x = 24 × 4

x = 24 × 4/12

x = 8 meters

Hence, the length of the shadow of Luke = 8 meters

If you study an extra 10 hours a week for a year (52 weeks) and you earn a four-year scholarship valued at $50,000, what is your hourly return on your investment in study time?

Answers

Answer:

 $96.15

Step-by-step explanation:

Step one:

given data

total number of weeks =52 weeks

study time per week is = 10 hours

total study time for the year = 52*10

=520 hours per year.

Step two:

given that the value of the scholarship for one year is $50,000.

we want to find the amount that an hour of study brings

so we have to divide the total scholarship by the amount of study time

50000/520

=$96.15

your hourly return on your investment in study time is $96.15

A triangle with side lengths of 8, 15, and 17.5 form a right triangle.

I would appreciate the help ​

Answers

9514 1404 393

Answer:

  false

Step-by-step explanation:

You can check to see if the sum of squares of the smaller two numbers is equal to the square of the larger.

  8² +15² vs 17.5²

  64 +225 vs 306.25

At this point, you need go no further. The sum of two integers will not have a fractional part, so cannot be equal to 306.25.

  289 vs 306.25 . . . . the long side is too long for a right triangle.

__

If you were familiar with some of the Pythagorean triples, you would know that the closest triple is {8, 15, 17}, so (8, 15, 17.5) does not represent a right triangle.

A few common Pythagorean triples are ...

  {3, 4, 5}, {5, 12, 13}, {7, 24, 25}, {8, 15, 17}, {9, 40, 41}

Polka Dot Boutique is having a sale of 15% off previously marked down items. Gwen finds a pair of jeans originally priced at $45.00 and marked down 25%. She must pay a 6% sales tax on the final prices of the jeans. How much does Gwen spend at Polka Dot Boutique? Group of answer choices

Answers

Answer:

$30.41

Step-by-step explanation:

Given that:

Discount off = 15%

Original price = $45

Mark down on item = 25%

Sales tax on final price = 6%

Cost of Jean will be ;

Mark down price :

Original price - (Original price * markdown %)

$45 - ($45 * 0.25) = $33.75

Discounted price :

Markdown price - (markdown price * discount %(

$33.75 - (33.75 * 0.15)

= $28.6875

Final price :

Discounted price + (sales tax * discounted price)

28.6875 + (0.06 * 28.6875)

= $30.40875

= $30.41

The cubic polynomial below has a double root at x=-4 and one root at x=6 and passes through the point (2,36) as shown. Algebraically determine it’s equation in factored form.

Answers

Answer: P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)

Step-by-step explanation:

The factored form of a polynomial is:

P(x) = A*(x - r₁)*(x - r₂)*(x - r₃)....

Where:

A is a real number.

r₁, r₂,.... etc

are the roots.

In this case, we know that the roots are:

-4, -4, and 6.

Then the polynomial will be:

p(x) = A*(x + 4)*(x + 4)*(x - 6)

Now we also know that this polynomial passes through the point (2, 36)

This means that:

P(2) = 36 = A*(2 + 4)*(2 + 4)*(2 - 6) = A*6*6*(-4) = A*(-144)

          36 = A*(-144)

        -36/144 = A

          -0.25 = -1/4 = A

Then the polynomial is:

P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)

Answer:

Step-by-step explanation:

Use Pythagoras's Theorem to find A

h²=y²+z²

10²=a²+6²

100=a²+36

∴a²=64

∴a=8

Use Pythagoras's Theorem to find A

h²=y²+z²

9²=b²+6²

81=b²+36

∴b²=45

∴b=3√5

x=a+b

=8+3√5

Answer:

a = 8

b = ∛5

x = 8 + ∛5

Step-by-step explanation:

I think here we have to do pythagorean theorem a² + b² = c² or c =√a² + b²

Now just plug in the numbers for 9, 6 and b

6² + b² = 9²

36 + b² = 81

b² = 45

b = 6.70820....

b = ∛5

∛5 = 6.70820..

Now plug in 6, 10, a

a² + 6² = 10²

a² + 36 = 100 (subtract 36 on both sides)

a² = 64

√64 = 8

a = 8

NOW X

8 + √45 = 14.708203

8 + ∛5 = 14.708203

x = 8 + ∛5

Add all the sides. But you are missing two sides. Soo since the top is 4, the bottom is two bc half is two. then the right side is 5 and the left, half is 2 so the other half is 3. 3+2=5! soooo the perimeter is 18.

Answer:

18

Step-by-step explanation:

We add up the side lengths,

[tex]5+4+3+2+2+2= 18[/tex]

by finding missing side lengths with subtraction and logic

and I'm pretty sure this is correct, but I like double-checking things.

This figure is made out of 2 rectangles,

2x5 and 3x2

The perimeter of each is 14 and 10

the two 3's are the over lapping sides

We also get 18.

The stopping distance, d ( in feet) for a van moving at a velocity (speed) v miles per hour is modeled by the equation:
d = 0.04v + 1.1v
What is the stopping distance for a velocity of 10 miles per hour?
a. 10 ft
b. 7 ft
c. 15 ft
d. 13 ft

Answers

Note: The must be [tex]0.04v^2[/tex] instead of [tex]0.04v[/tex].

Given:

The stopping distance, d ( in feet) for a van moving at a velocity (speed) v miles per hour is modeled by the equation:

[tex]d=0.04v^2+1.1v[/tex]

To find:

The stopping distance for a velocity of 10 miles per hour.

Solution:

We have,

[tex]d=0.04v^2+1.1v[/tex]

where, d is stopping distance and v is velocity.

Substitute v=10  in the given equation to find the stopping distance for a velocity of 10 miles per hour.

[tex]d=0.04(10)^2+1.1(10)[/tex]

[tex]d=0.04(100)+11[/tex]

[tex]d=4+11[/tex]

[tex]d=15[/tex]

So, the stopping distance for a velocity of 10 miles per hour is 15 ft.

Therefore, the correct option is c.
