Let f(x) =x+5 and g(x)=x^2-3 then f(g(x)) =?
guajiro [1.7K]

Answer:

Option (a) is true.

Step-by-step explanation:

Given the function

f(x)=x+5

g\left(x\right)=x^2-3

(f∘g)(x) = f(g(x)) = f(x²-3) = (x²-3)+5

                                      = x² + 2

Thus,

f(g(x)) = x² + 2

Therefore, option (a) is true.

Find the value of x.
Novay_Z [31]

Answer:

x = 50°

Step-by-step explanation:

Angles in a quadrilateral add to 360°

First work out the interior missing angle

360° - ( 40° + 80° + 110° ) = 130°

Angles on a straight line add to 180° so

180° - 130° = 50°

Find the mass and center of mass of the lamina that occupies the region D and has the given density function rho. D is the trian
Pachacha [2.7K]

Answer:

m=1/300 du

Step-by-step explanation:

we have that m=∫∫rho(x,y)dA for this we must find the limits of integration (according to the graph1)

On the x axis: if y=2x and x+2y=1 then y=2x and y=(1-x)/2 ⇒ 2x=(1-x)/2 ⇒ 4x=1-x ⇒ 5x=1 ⇒ x=1/5; on the y axis y=0 and y=1/2

m=∫∫rho(x,y)dA (view the graph 2)
