Identify the composite function and its domain

creativ13 [48]

$f(g(x))=f(\sqrt{x-2})$
$f(g(x))=3(\sqrt{x-2})^{2}+4$
$f(g(x))=3(x-2)+4$
$f(g(x))=3x-6+4$
$f(g(x))=3x-2$

Domain:
g(x) must be greater than or equal to zero (no square roots of negative numbers) therefore x must be greater than or equal to 2. Answer is B.

Elijah wants to know the cross-sectional area of the circular pipe. He measures the diameter which he finds, to the nearest mill

Tanya [424]

Answer:

The area is 0.002m² to 3 dp

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes(I.e cross sectional area of pipe ) , this time the a circle.

It requires us to look for the area of the shape

Given data

Diameter d = 5cm

Converting to mm = 5/100= 0.05m

Radius of circle r=d/2=0.05/2 =0.025mm

Given the area of the circle

A=πr²

A=3.14*0.025²

A=0.0019m²

To 3 dp we have area as 0.002m²

KJ=3x+12 And KH=6x-15. What is KG?

Andreyy89

Answer:

Step-by-step explanation:

3x + 12 = 6x - 15

6x - 3x = 12 + 15

3x = 27

x = 9

KJ = KH = KG = 3x + 12

KG = 3.(9) + 12

KG = 27 + 12

KG = 39
