Answer:
B
Step-by-step explanation:
a^2 + b^2 = C^2
solve for b
b^2 = c^2 - a^2
square root on both sides of the equation and you get option b as your answer
First, we get ax^2+bx+c. Next, we know that the line of symmetry is -b/2a. Since we know that there is a maximum value, the parabola is facing downwards, so a is negative. For random numbers, we can say that a = -0.5 and b=-10 (b needs to be negative for -b/2a to equal -10), getting -0.5x^2-10x+c. Plugging -10 in for x (since -10 is the middle it is the max), we get -50+100=50. Since the maximum needs to be 5, not 50, we subtract 45 from the answer to get it and therefore make c = -45, getting -0.5x^2-10x-45
60% = 0.6
12 / 0.6 = 20
answer 12 is 60% of 20
Answer:
3 cans
Step-by-step explanation:
A = lw
a = 20 x 8 = 160
a = 40 x 8 = 320
Together this is 480
I would need 3 cans.
To know if there is a perfect square you gotta see if there is a minus sign before the second coefficient and when you square the second coefficient divided by 2 you should get the third coefficient
