Answer:

Ratio is 11 : 13

Step-by-step explanation:

We are given;

Time to develop estimate = 30 minutes

Time to do the job = 2 hours 45 minutes = (2 * 60) + 45 = 165 minutes

Total time to develop and do job = 165 + 30 = 195 minutes

Thus;

Ratio of time spent on job to total time = 165 : 195

Whrn this is broken further, we have; 11 : 13

Find the value C(-2), where C is defined below.<br> C(x) = -3x2 – 3x - 3
Harman [31]

Answer:

C(-2) = -9

Step-by-step explanation:

Step 1: Define

C(x) = -3x² - 3x - 3

C(-2) = x = -2

Step 2: Substitute and Evaluate

C(-2) = -3(-2)² - 3(-2) - 3

C(-2) = -3(4) + 6 - 3

C(-2) = -12 + 6 - 3

C(-2) = -6 - 3

C(-2) = -9
