Answer:

(x-2)²+(y-4)² = 25

Step-by-step explanation:

Standard equation of a circle is expressed as

(x-a)²+(y-b)² = r²

Center = (a, b)

Radius = r

Get the radius

r² =(0-4)²+(-1-2)²

r² = (-4)²+(-3)²

r² = 16 + 9

r² = 25

Centre = (2, 4)

Substitute into the equation

(x-2)²+(y-4)² = 25

This gives the required equation

Well, 4+1=5, so we need to first find:
$150 \div 5 = 30$
Ivan gets
$30 \times 4 = 120$
Tanya gets
$30 \times 1 = 30$
$120 - 30 = \boxed{90}$

Answer:

Step-by-step explanation:

1) Step 4: Marc has converted radical form to exponent form

Step 5: He has evaluated the value of the radical

$x = \sqrt[3]{8}$

Here, 3 is index and 8 is radicand.

Prime factorize 8 and for every 3 numbers we can take one number outside the radical

Solution:

$x = \sqrt[3]{2*2*2}\\\\x = 2$

4) No,my equation does not have an extraneous solution.

My solution, satisfies the equation
