Hello,

The circle has like equation: (x+3)²+(y-2)²=r²

If x=1 then y=5 ==>(1+3)²+(5-2)²=r²==>4²+3²=r²==>r=5 (the radius)

if x=-7 then (-7+3)²+(y-2)²=25 ==>  (y-2)²=25-16==>y=2+3 or y=2-3
The points (-7,5) and (-7,-1) are on the circle.

Musya8 [376]
Hello,

After decrypting the question:

f(x)=2x^4-4x^3-11x^2+3x-6

f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3*(-2)-6=2*16+32-44-6-6=8

Express the calculation “four times as large as 124+645”
Effectus [21]

The calculation of the expression “four times as large as 124+645” end up in 1141.

<u>Step-by-step explanation:</u>

  • The question is asked to Express the calculation “four times as large as 124+645”.
  • The given statement can be written in the expression form to perform the calculations.

Here, the phrase 'four times' represents the multiplication of 4.

⇒ “four times as large as 124+645” = 4(124) + 645

So, the first step is to multiply 4 with 124.

⇒ 4 × 124

⇒ 496

The expression is now modified as “496+645"

We know that, the final result is the addition of the two numbers 496 and 645 which is calculated as

⇒ 496+645

⇒ 1141

Therefore, the calculation of the expression “four times as large as 124+645” end up in 1141.

scoundrel [369]
Hello there,

We need to remember that Mode means: the number that appears more than others.

18 is your answer.
