Question

(60t^2-10t)/(10t)+(9u+5)/2 если t=0,1 u=-3

Answer 1

6t-1+4,5u+2,5

0,6-1-13,5+2,5=-11,4

Answer 2

To evaluate the expression, simply plug in the given values of t and u into the expression:

Let t = 0.1 and u = -3.

(60t^2 - 10t) / (10t) + (9u + 5) / 2

Now, substitute the values:

(60 * (0.1)^2 - 10 * 0.1) / (10 * 0.1) + (9 * -3 + 5) / 2

Simplify each part:

(60 * 0.01 - 1) / 1 + (-27 + 5) / 2

(0.6 - 1) + (-22) / 2

-0.4 - 11

Now, add the terms:

-11.4

So, the value of the expression when t = 0.1 and u = -3 is -11.4.
