Question

0,25a-4c2 при a=4 c=3 a=0,1 c=1/2​

Answer 1

0,25×4-4×3×2= 1-12×6 = 1-72 = -71

0,25×0,1- 4× 1/2×2= 0,025- 4= -3,975

Answer 2

It seems like you want to evaluate the expression "0,25a-4c2" for two sets of values of variables "a" and "c". The expression involves two variables, "a" and "c", and you want to substitute different values into these variables and then perform the calculations. Let's go through the calculations step by step:

1. First, let's substitute the values a=4 and c=3: 0.25 * 4 - 4 * 3^2 = 1 - 4 * 9 = 1 - 36 = -35

2. Now, let's substitute the values a=0.1 and c=1/2: 0.25 * 0.1 - 4 * (1/2)^2 = 0.025 - 4 * 0.25 = 0.025 - 1 = -0.975

So, when a=4 and c=3, the result is -35, and when a=0.1 and c=1/2, the result is -0.975.
