Answer: The center is (5,-1) and radius is 6.

Step-by-step explanation: The equation: (x-h)^2+(y-k)^2=r^2 is really important. Since we have 36 equal r^2, square root it to get 6. And the center would be 5, because (x-5) but do the opposite operation, same for y+1.

36 miles is equal to 1 hour ( 60 minutes)

Do a ratio,,

36 : 60
87 : ?

To work out the unknown ratio, do 60/ 36 and then multiply by 87 to get

145 minutes. To convert that into hours you would get 2 hours and 25 minutes

Add that on to 07 00

He would get there at 09 25

Hope this helps! Any questions let me know :)

Find the absolute value of |5+12i|

larisa [96]

Answer:

Step-by-step explanation:

The distance that $a+bi$ has from $0+0i$ is:

$\sqrt{(a-0)^2+(b-0)^2}$

$\sqrt{a^2+b^2}$

So let's just apply the formula there:

$\sqrt{(5)^2+(12)^2$

$\sqrt{25+144}$

$\sqrt{169}$

$13$

Kareem Heats a beaker of water to a boil then he record that the water temperature decreases from 100 degrees Celsius to 19 degr

Advocard [28]

To solve for the problem, we list first all the given

Given:

Initial temperature, T1 = 100 degC
Final temperature, T2 = 19 degC
Time, t = 5 2/5 mins or 5.4 mins

Required: Change in temperature per minute

Solution:

Change in temperature per minute = (T1-T2)/t
Change in temperature per minute = (100 degC - 19 degC)/5.4 mins
Change in temperature per minute = 15 degC/min

<em>ANSWER: 15 degC per minute</em>
