Answer:
Step-by-step explanation:
Given that there are two vectors U = (-8,0,1)
V = (1,3,-3)
To find projection of u on V and also projection of V on U
First let us find the dot product U and V
U.V = 
Projection of U on V =
Similarly projection of V on U
=
Answer:
B
Step-by-step explanation:
The square of y would look like y^2 and decreased means subtraction
So the equation now y^2-
the quotient of 8 and y would be 8/y
The full equation is y^2-8/y
Answer: b= 58a (divided 348 by 6 and take the equation b = ka and substitute k with 58)
Answer:
cubic units.
Step-by-step explanation:
You can use this formula for calculate the volume of a cone:

Where "r" is the radius and "h" is the height.
You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:


Answer:
He needs 5x+56 ft
Step-by-step explanation:
To find how much of fencing he needs , we find the perimeter of the given figure
All sides are equal in a square
To find perimeter of the square we add all the sides
4 sides we have for the square
one side is x, so perimeter of square = x+x+x+x= 4x
Now we find perimeter of rectangle
Opposite sides of rectangle are equal
Here for rectangle we consider only three sides
because fourth side is common for rectangle and square
So perimeter of the rectangle (with 3 sides) = 28 +x+ 28 = 56+x
Total fencing = perimeter of square + perimeter of rectangle
4x + 56 + x= 5x+56
