Answer:
Step-by-step explanation:
The given pyramid is a square based pyramid. The formula for determining the total surface area of a square base pyramid is expressed as
Total surface area = base area + (1/2 × perimeter × slant height)
Perimeter of base = 4 × 756 = 3024 feet
Slant height = 612 feet
Base area = 756² = 571536 feet²
Total surface area = 571536 + (1/2 × 3024 × 612) = 1496880 feet²
Total surface area of the pyramid today is
571536 + (1/2 × 3024 × 592) = 1466640 feet²
Change in total surface area is
1496880 - 1466640 = 30240 feet²
To do this problem you would first need to factor out a variable, which in this case I would want to do the first equation because it is isolated. Now the equations would look like this:
x = -2y - 1
4x - 4y = 20
Since we know that x is now equal to -2y - 1 we can plug it in to the x value in the second equation:
4 (-2y -1) - 4y = 20
-8y -4 - 4y
-12y - 4 = 20
-12y = 24
y = -2
Now that we know the y value plug the y value to one equation to find the x, I will be using the first equation
x + 2(-2) = -1
x - 4 = -1
x = 3
Solutions:
y = -2
x = 3
Answer:
-1

Answer:
y-1 = 5/3(x-3)
Choice C
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
(3,1) (6,6)
m = (6-1)/(6-3)
m = (5/3)
the point slope form of a line is given by
y-y1 = m(x-x1)
You have point (3,1)
y-1 = 5/3(x-3)
Choice C
