1) first step
you must do( a+b) ^2 = a^2+2ab+b^2
then
2)second step
y = -3(x+1)^2 +4 = -3( x^2+2x+1) +4⇒ y = -3x^2-6x-3 +4, y = 3x^2-6x+1
now the graph of this function is
Answer:
x= 6
Step-by-step explanation:
Answer:
62 units^2
Step-by-step explanation:
The surface area of the prism is the area of the net. It consists of a vertical rectangle 3 units wide and 14 units high, which has an area of ...
(3 units)(14 units) = 42 units^2
and two "wings" that are each 5 units wide and 2 units high, so have an area of ...
(2)(5 units)(2 units) = 20 units^2
Then the total surface area is ...
42 units^2 +20 units^2 = 62 units^2
I believe the answer is 4. I did an assignment and got it right
Answer: Below
Step-by-step explanation:
Well they already gave you crucial information. The radius, or r, is 19, and pi can be substituted with 3. Using that we can do:
C = 2 * 3 * 19
C = 6 * 19
C = 114
Our answer is 114.
