Me and explain this problem to me cuz i don't understand
will give

for the first one, let's notice something, its base has a diameter of 8 inches, meaning its radius is 4, and it has a slant height of 7 inches, thus

the 2nd one, is just a right-circular cylinder, with a diameter of 34, thus a radius of half that or 17, and a height of 27

the third one is a square pyramid, namely one of its faces is a square, so it'll be the one on the left-hand-side, the rest are just triangles.

we're looking for the lateral area, namely the area of the sides, namely excluding its base, well, this pyramid is resting on a triangular face, so we'll be excluding that and including the square and the other three triangles.

let's notice, the square is just an 8x8, and the triangles have a base of 8, and an altitutde/height of 22.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
