Answer:

f(- 2) = 8

Step-by-step explanation:

Evaluating for x = - 2

f(- 2) = 2(-2)^{4} - 4(- 2)³ - 11(- 2)² + 3(- 2) - 6

       = (2 × 16) + (- 4 × - 8) + (- 11 × 4) - 6 - 6

       = 32 + 32 - 44 - 6 - 6 = 8

Answer:  (C) shifts 6 units to the LEFT

<u>Step-by-step explanation:</u>

The vertex form of an absolute value equation is:

y = a |x - h| + k    where;

  • a is the vertical stretch (irrelevant for this problem)
  • (h, k) is the vertex

Since h represents the x-coordinate and the x-axis is left to right, then h shifts  the graph left or right.

  • If h is negative, the graph shifts to the left.  
  • If h is positive, the graph shifts to the right.

x + 6 is actually x - (-6), so h is negative and the graph shifts to the left.

Last year Peter spent a total of 8 1/6 hours on community service. Visits to old folks' homes made up 4/7 of the total time. How
zhannawk [14.2K]

Answer:

A. 4 2/3 hours

B. (i) 9 4/5 hours

(ii) 1 19/30

Step-by-step explanation:

Firstly, to find the number of hours he used in visiting old folks, what we have to do is to multiply the fraction of hours he used by the total number of hours.

Mathematically, that would be;

4/7 * 8 1/6

8 1/6 is same as 49/6

So the number of hours he spent visiting old folks would be ;

49/6 * 4/7 = 14/3 = 4 2/3 hours

B. What we do here is simply multiply the fraction now by what he spent last year.

That would be 1 1/5 * 8 1/6 hours

= 6/5 * 49/6 = 49/5 = 9 4/5 hours

ii) Now we want to know how much more time will be spent this year than last year.

What to do here simply is to subtract the time taken last year from what we have this year

That would be;

49/5 - 49/6 = 49/30 = 1 19/30
