Answer:
Step-by-step explanation:
Because the function intersects its midline at 
, then the midline is 
.
Additionally, the amplitude is just the positive distance between the maximum/minimum and the midline, so the amplitude is 
.
Also, given that period is 
and the fact that the period is 
from our given maximum, we have the equation 
where 
.
Lastly, to find 
, we know that the phase shift, 
, is 
(or 
to the left) since 
. Therefore, we have the equation 
where 
.
Putting it all together, our final equation is
Answer:
1,2, 1,203, 12,03, 12,3, 12,301
Step-by-step explanation:
1,2 → 1,200
1,203
12,3 → 12,300
12,301

Answer:
30 PS4's
Step-by-step explanation:
The manager chose 50/500 PS4's to sample
3/50 were defective
To find how many were defective in all 500, we multiply the fraction by a number that makes the 50 (the sample), into a 500(the total).
That number is 10
Whatever multiplication you do to the bottom of a fraction, you do to the top
3*10 / 50*10
30 / 500 are likely to be defective
Step-by-step explanation:
Larval mosquitoes breath through trachea in their siphons. This is a structure analogous to the snorkel on a diesel electric submarine. It allows for gas exchange with the atmosphere while the remainder of the insect is submerged. The opening of the siphon is hydrophobic so it won’t get wet and blocked by water. This works well to keep the siphon and the trachea open under normal conditions. Oil when poured on water forms a thin film. When there are mosquitos in that water, when their siphons contact the oil layer, the oil wets and blocks their siphons and suffocates the mosquitoes. This works against most, but not all mossies, as evolution is an amazing process. Some mosquitoes (Mansonia, Coquilletidia) have a siphon designed to penetrate the air vessels in aquatic plants and they don’t need to come to the surface to breath like other mossies. So oil won’t work on these genera.
