(x-13.4)^2+(y+2.6)^2=100
oee [108]

Answer:radius =10 units

Step-by-step explanation:

Given

Equation of circle is given by

(x-13.4)^2+(y+2.6)^2=100\quad \ldots(i)

Now general equation of circle with center (h,k) with radius r is given by

(x-h)^2+(y-k)^2=r^2\quad \ldots(ii)

Comparing (i)  and  (ii)  we get

h=13.4

k=-2.6

r=10

Thus center is (13.4,-2.6)

and radius r =10\ units

January 30,2019 was the coldest day in minieapolis-St. Paul in over 20 years. The lowest tempeauture recorded that day was -28F.
klio [65]

Answer:

<h2>The warmest temperature was -13F</h2>

Step-by-step explanation:

We are expected to compute the warmest temperature recorded at Minneapolis

Step one:

We are told that on January 30th of 2019 was the coldest day at Minneapolis

hence the temperature reading= -28F------this is like 28 points away from 0 on the number line

Step two:

We are given that the warmest temperature recorded is 15F higher.

since the -ve sign represent cold or snowy weather, the warm temperature

is gotten by adding 15F to the negative temperature

=-28+15

= -13F

<u>The warmest temperature was -13F</u>
