You are making a sculpture that is a pyramid with a square base . You want the height of the pyramid to be 4 inches less than the length of a side of the base . You want the volume of the sculpture to be 200 cubic inches .
a . Let x represent the length ( in inches ) of a side of the sculpture's base . Draw a diagram of the sculpture , and label the dimensions in terms of x .
b . Write a function that gives the volume V of the sculpture in terms of x .
Vector A =5i+2j and vector B =2i−3j+4k.
a) What is the cross product A⃗ ×B⃗ ? Find the x-component.
b)Find the y-component.
c)Find the z-component.
I do not know how to get started with my graph. Does my x axis need to be between 7.84 or 15.68 and my y axis between 0.779 or 1.558. If so how should I start my graph and how much should I go up by with both x and y axis's. Please help! I am confused.
