Ramon is graphing the function f(x) = 3(4)x. He begins by plotting the initial value. Which graph represents his initial step? On a coordinate plane, the point (0, 3) is graphed. On a coordinate plane, the point (0, 4) is graphed. On a coordinate plane, the point (3, 0) is graphed. On a coordinate plane, the point (4, 0) is graphed.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

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

d.) yes, because the volume of the cone is greater than the volume of the sphere
