Mac has 1/4 hour left of track practice and must be completed 8 laps around the track before he leaves which equation can be use

telo118 [61]

Answer:

(a) $Unit = \frac{1}{4}/8$

Step-by-step explanation:

Given

$Time = \frac{1}{4}$

$Lap = 8$

Required

Determine the time in each lap

The unit time in each lap is calculated by dividing the total time by the number of laps; i.e.;

$Unit = \frac{Time}{Lap}$

Substitute values for Time and Lap

$Unit = \frac{1}{4}/8$

Hi ! How to solve this question?

tester [92]

You should actually have

$-x^2-4x-10=-(x^2+4x+10)=-(x^2+4x+4+6)=-((x+2)^2+6)=-(x+2)^2-6$

Now, remember that $x^2$ is always non-negative, so $(x+2)^2\ge0$ for any value of $x$ . This means $-(x+2)^2\le0$ for any $x$ , and so

$-(x+2)^2-6\le0-6=-6$

i.e. f(x) is at most -6, and hence negative for all $x$ .
