(a) y = 3(x^2 -4x) +17 = 3(x^2 -4x +4) +17 -3*4
y = 3(x -2)^2 +5
The turning point at (2, 5) is a minimum.
(b) y = -5(x^2 -8x) -70 = -5(x^2 -8x +16) -70 +80
y = -5(x -4)^2 +10
The turning point at (4, 10) is a maximum.
Normally You would need to simplify all of them, to see what their values are like.
Already from the start, however, we can see that 9n + 3 + 2 and 9n + 11 isnt the same value. Based on this, we should only need to simplify one of the other, to get either 9n + 5 or 9n + 11.
Lets pick the upper one.
(4n + 3) + 5n + 8 - 6
4n + 3 +5n + 2
9n + 5.
This indicated that 9n+11 is the odd one.
To make sure, we can solve the next one:
(4n + 5n) + (3 + 8 - 6)
9n + 5
Which indicated the same thing.
9n+11 is the "outsider", which means:
9n + 11 is the correct answer for this task.
Answer:
452.16 units^2
Step-by-step explanation:
Given
Radius = r= 6 units
The formula for finding the surface area of a sphere is:
In the formula, π is taken as 3.14.
So, the surface area of the given sphere is 452.16 units^2 ..
Answer:
1.75
Step-by-step explanation:
used a calculator
They each would get 2400 because it says Tammy and Qiulian has 2400. Then you would multiply 2400*2=4800 and Tammy will Give Qiulian 2400 for them to have the same amout
