You would need to use the distance formula.
Distance = Sqrt((x2-x1)^2+(y2-y1)^2)
Plug in your numbers
Distance = Sqrt((12+4)^2+(12-18)^2)
Distance = 17.09

Aleksandr [31]

Answer:

option (a)

Step-by-step explanation:

Length of long dimension = 11400 km

It means it is the length of major axis.

So, the length of semi major axis = 11400 / 2 = 5700 km

Thus, the length of semi major axis is 5700 km.

Monica paid sales tax of $105 when she bought a new TV. If the sales tax is 5%, what was the cost of the TV?​
mezya [45]

Answer:

$31.5

Step-by-step explanation:

X * 5% = $1.50

X = $1.50 / 5%

Or by using simple rule of three:

If 5% is $1.50

Then 100% is X

So you obtain = $30

Now you just need to sum The net prices and the taxes

Net + tax = Total Charge

$30 + $1.5 = $31.5

Navin gave his brother 1/5 of his money and her sister 5/8 of the remainder. Navin remained with $12.00 (a) Calculate how much m
MrRa [10]

Answer:

$40

Step-by-step explanation:

Fraction Navin gave his brother = 1/5

Remainder = 1 - 1/5

5/5 - 1/5 = 4/5

Fraction Navin gave his sister = 4/5 x 5/8 = 1/2

total amount Navin gave his siblings :

\frac{1}{5} + \frac{1}{2}

\frac{2 + 5}{10} = \frac{7}{10}

Fraction that remains = 1 - 7/10

10/10 - 7/10 = 3/10

Let a = amount Navin has initially

3/10 x a = 12

a = (12 x 10) / 2  = $40

2. Factor f(x) = x4 + x3 – 8x2 + 6x + 36 completely. Then sketch the graph.
arsen [322]
The complete factorization of f(x) = x4 + x3 – 8x2 + 6x + 36 is f(x) = <span>(x+2) (x+3) (x^2-4x+6).

See attached picture for the sketch of the graph of the function. To sketch the graph, simply substitute values of x into the function in order to get its specific values of f(x) = y. Plot these values in the cartesian plane. I hope this helped you a lot.</span>
