posledela

Answer:

x - 16.1°C

Step-by-step explanation:

Given that average low temperature in January is 16.1 cooler Than average low temperature in November

Let average low temperature in November = x

Since, average low temperature in January is cooler than average low temperature in November, then, January temperature is less Than in November

Hence,

Average low temperature in January :

[Average low temperature in November - 16.1°C]

(x - 16.1°C)

Write the equation for a circle with it's center at (9,7) and with a solution point at (-6,2)

Roman55 [17]

Answer:

Step-by-step explanation:

The equation for a circle is

$(x-h)^2+(y-k)^2=r^2$

We have an h, k, x, and y; we need to find r-squared. Filling in:

$(-6-9)^2+(2-7)^2=r^2$ which simplifies to

$-15^2+-5^2=r^2$ which simplifies to

$225+25=r^2$ which means that

$r^2=250$

Our equation, then, is

$(x-9)^2+(y-7)^2=250$

The diagram represents two statements: p and q.

postnew [5]

Answer:

A. $p\vee q$

Step-by-step explanation:

We are given that

A region: It includes all element of p but not q.

B region: It includes elements of p and q.It is represented by

$p\wedge q$ .

C region: it contained the elements of q only.

Union of A , B and C are represented by

$p\vee q$

Hence, the region A,B and C represents by

$p\vee q$

Option A is true.
