Why do we use coordinate planes to do<br> transformations and dilations?

gogolik [260]

Answer: a coordinate plane is used in order to track the location of the object.

Translations are congruence transformations that move an object, without changing its size or shape

Dilations are transformations that generate an enlargement

In the Mississippi River Delta, fresh water (0% salinity) mixes with salt water from the Gulf of Mexico (3 1 2% salinity). If 1,

Rina8888 [55]

Answer:

The total resulting gallons of water is 4,000 gallons

The concentration of the resulting solution is 2.625% salinity

Step-by-step explanation:

The salinity of the fresh water from the Mississippi River Delta = 0%

The salinity of the water from the Gulf of Mexico = 3 1/2%

Therefore, if 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, we have;

The total resulting gallons of water = 1,000 + 3,000 = 4,000 gallons

The total resulting gallons of water = 4,000 gallons

The concentration of the resulting solution is found as follows;

The concentration of the resulting solution = (3 × 3 1/2)/400 × 100 = 2.625%

The concentration of the resulting solution = 2.625% salinity.

When doctors prescribe medicine, they must consider how much the drug’s effectiveness will decrease as time passes. If each hour

Darya [45]

Answer: The level of the dose be after 3 hours= 0.03125 mg.

Step-by-step explanation:

General exponential decay equation : $y=A(1-r)^x$ , where A = initial value , r= rate of decay , x =Time period.

Here, drug’s effectiveness is decreasing exponentially.

AS per given , we have

A= 250 mg

x=3

r= 95% = 0.95

Then, $y=250(1-0.95)^3 = 250(0.05)^3=250*0.000125=0.03125$

Hence, the level of the dose be after 3 hours = 0.03125 mg.
