1 answer:

3 0

By graphing the given points, we will get the attached figure
which represents:
f(x) = 3 sin x
but sin x = cos (x - π/2)
∴ f(x) = 3 cos ( x - π/2 )

The correct choice is option ⇒⇒⇒ f(x) = 3 cos(x − pi over 2 )

Joan waters her plants each day with gallons of water. With a new irrigation system in place, she uses gallons of water each day

vampirchik [111]

Answer:

$172\frac{1}{2}$ gallons

Step-by-step explanation:

Considering she waters her plants with 25 1/2 gallons i.e 51/2

and with the new system, she does it with 19 3/4 i.e 79/4

taking the difference:

$\frac{51}{2} - \frac{70}{4}$ = $\frac{23}{4}$ gallons per day

For 30 days:

30 x $\frac{23}{4}$ = 172.5 or $172\frac{1}{2}$ gallons

Find the endpoint of the line segment

blondinia [14]

Answer:

(29,-13)

Step-by-step explanation:

You can tackle this for x and y coordinate separately.

For x, the line starts at -9 and is halfway at 10. The distance between -9 and 10 is 19 so it has another 19 to go, which puts the endpoint at 10+19=29.

Same for y: from 7 to -3 is 10 down, another 10 to go, puts you at -13.

Formula: x,y of midpoint is ((x1+x2)/2, (y1+y2)/2)
