Answer:
EX. 210/6
Step 1. Set up the equation, 210/6
Step 2. Divide the first digit/number 6 x 30 = 180 210 - 180 = 30
Step 3. rewrite the equation that is left, 30/6 6 x 5 = 30 30 - 30 = 0
Step 4. Only if need be for another equation, repeat step 1 and 2 until you have your answer
The Answer to the equation 210/6 is 35
Try 426/6 by yourself, please don't use a calculator.
Y = -(1/2)(x-2)² +8
Re write it in standard form:
(y-8) = -1/2(x-2)² ↔ (y-k) = a(x-h)²
This parabola open downward (a = -1/2 <0), with a maximum shown in vertex
The vertex is (h , k) → Vertex(2 , 8)
focus(h, k +c )
a = 1/4c → -1/2 = 1/4c → c = -1/2, hence focus(2, 8-1/2) →focus(2,15/2)
Latus rectum: y-value = 15/2
Replace in the equation y with 15/2→→15/2 = -1/2(x-2)² + 8
Or -1/2(x-2)² +8 -15/2 = 0
Solving this quadratic equation gives x' = 3 and x" = 2, then
Latus rectum = 5
Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area
Pyramid Surface Area = (.5 * 56 * 11) + 14 * 14Pyramid Surface Area = 308 + 196Pyramid Surface Area =504 square millimeters
