Answer:

Step-by-step explanation:

f(x)=-4x+2

g(x)=x²+1

(gof)(x)=g(f(x))=g(-4x+2)=(-4x+2)²+2=16x²-16x+4+2=16x²-16x+6

(gof)(3)=16(3)²-16(3)+6=144-48+6=150-48=102

Answer:

Step-by-step explanation

2. you gave that there is a 40% chance that her instructor will be watching, which means that there is a 60% chance he will not be watching (100% - 40%).

3. you gave that there is a 90% chance of making a bull's eye, and 40% chance the instructor will be watching

since those two events are independent of each other, the chance of both of them happening is the product of the two chances, namely 0.9 x 0.4 = 0.36, or 36%

Step-by-step explanation:

To find the surface area of a cone, one uses the following formula,

$A=(\pi)(r)(r+\sqrt{h^2+r^2}})$

Where (r) is the radius of the base of the cone, and (h) is the height of the cone, ( $\pi$ ) represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
