. 1 Find f for the function f. f(x) = 3x² + 3, x > 0 And find the domain

konstantin123 [22]

Answer:

y = $\sqrt{\frac{x-3}{3} }$

Domain = [3, infinity)

Step-by-step explanation:

x = 3y^2 + 3

3y^2 = x - 3

y^2 = (x-3)/3

y = $\sqrt{\frac{x-3}{3} }$

natulia [17]

R=I+6 S=4R I

I+(I+6)+4(I+6)=126

Basic algebra (I dont know how to show it) leaves you with: 6I = 90, divide both sides by 6 and I=15

a circle has a center at 8,2 the point 3, 7 is on the circle, what is the area of the circle to the nearest tenth

BartSMP [9]

We have to calculate the radius
Radius: Distance between the points (8,2) and (3,7)

Given two points (x₁,y₁) and (x₂,y₂) the distance between these points will be:
Distance=√((x₂-x₁)²+(y₂-y₁)²)

In this case:
Distance=radius=√((3-8)²+(7-2)²)=√(25+25)=√50

Area of a circle=πr²
Data:
r=√50

Therefore:
Area of this circle=π((√50) u)²=50π u²≈157.1 u².

Answer: the area would be: 50π u² or 157.08 u²
