Answer:

x or AB = 9

Step-by-step explanation:

Use Pythagorean Theorem to solve for missing side.

Pythagorean Theorem: a² + b² = c²

Plug our sides in to get AB² + BC² = AC²

We are solving for AB so we arrange the equation to get:

AB² = AC² - BC²

Solve for AB:

AB² = (√117)² - (6)²

AB² = 81

AB = 9

x or AB = 9

Step-by-step explanation:

-(38/21)

that is the answer

Answer:

-38/21, or 1 17/21

Step-by-step explanation:

To add, we need to change the denominators to be the same. The least common denominator is 21. -8/7 is equal -24/21, and -2/3 is equal to -14/21. If we add these we get -38/21, or 1 17/21.

Step-by-step explanation:

Supposing a cost of $30,000, and using proportions, it is found that you would have to save $1,083.30 each month.

--------------------------

We can solve it using proportions, by the following rule of three:

1 month - $x

24 months - $26,000

Applying cross multiplication:

[tex]24x = 26000[/tex]

[tex]x = \frac{26000}{24}[/tex]

[tex]x = 1083.3[/tex]

You would have to save $1,083.30 each month.

If Jim paid $48 to buy a package of 6 flea treatments for his dog. Then cost of one treatment is $6.

A division is a process of splitting a specific amount into equal parts.

Given,

Jim paid $48 to buy a package of 6 flea treatments for his dog

We need to find what is the cost a per treatment.

We have to divide split forty eight by six to find the cost of each treatment.

Forty eight divided by six

$48/6

When we divide by six we will get six.

$6

Hence if Jim paid $48 to buy a package of 6 flea treatments for his dog. Then cost of one treatment is $6.

Answer:

Your answer is 24 3/4 if you want it decimal wise it would be 24.75

Step-by-step explanation:

Well, let's set up our equation first. 10 (she jumped down 10 feet) + 2(7 3/8) (we are multiplying this by 2 because she first went under the surface then went back up to the surface)

Since distance is never negative you won't add any negative symbols, you'll simply add. First 2(7 3/8) = 59/4 or 14 3/4 | Next we add 10 to it 14+10 = 24 3/4

Your answer is 24 3/4 if you want it decimal wise it would be 24.75

First, according to the information, we build a linear model, and then, the model is used to find the information asked.

a) The linear model is:

[tex]V(t) = 224000 - 6800t[/tex]

b) The depreciated value of the boat after 10 years is of $156,000.

c) The depreciated value falls below $100,000 after 18.24 years.

d) The sketch is given at the end of the answer.

Item a:

[tex]m = \frac{115200 - 224000}{16} = -6800[/tex]

Then, the linear model is:

[tex]V(t) = 224000 - 6800t[/tex]

Item b:

The value after 10 years is V(10), so:

[tex]V(10) = 224000 - 6800(10) = 156000[/tex]

Then, the depreciated value of the boat after 10 years is of $156,000.

Item c:

This is t for which: V(t) = 100000. So

[tex]V(t) = 224000 - 6800t[/tex]

[tex]100000 = 224000 - 6800t[/tex]

[tex]6800t = 224000 - 100000[/tex]

[tex]6800t = 124000[/tex]

[tex]t = \frac{124000}{6800}[/tex]

[tex]t = 18.24[/tex]

The depreciated value falls below $100,000 after 18.24 years.

Item d:

The sketch is appended at the end of this answer.

Answer:

  4a +4

Step-by-step explanation:

The average rate of change of f(x) on the interval is ...

  (f(a) -f(1))/(a -1)

  = ((4a² -6) -(4(1)² -6))/(a -1) = (4a² -4)/(a -1)

  = 4(a² -1)/(a -1) = 4(a +1) = 4a +4

The average rate of change on the interval is 4a +4.

Answer:

  center (-5, 3)

  radius 3

Step-by-step explanation:

Compare the given equation to the standard form equation of a circle:

  (x -h)² +(y -k)² = r² . . . . . . circle with center (h, k) and radius r

This shows us that ...

  -h = +5   ⇒   h = -5

  -k = -3   ⇒   k = 3

  r² = 9   ⇒   r = √9 = 3

Then the circle center is (h, k) = (-5, 3), and the radius is r = 3.
