I will mark you brainliest! The value of a car decreases by 1/6 every year. What type or function represents this pattern?
d1i1m1o1n [39]

Answer:

C

Step-by-step explanation:

When the value of something decreases by a certain factor every unit of time, instead of by a set constant, then this is called exponential decay. When the rate is constant, this is called linear decay. Hope this helps!

Find the equation of line parallel line to y=2x+7 and that goes through the point 4,12
Step2247 [10]
Y= 2x+4, because when you plug in x and y you then solve for b and get 4. The 2x is the same because the slope stays the same on parallel lines.

A man bought a cow and a horse for $500. He sold the cow at a profit of 10% and the horse at a loss of 10% and suffered a loss o
ycow [4]

Answer:

<em>The man paid $200 for the cow</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's call:

x = price of the cow

y = price of the horse

The man bought the cow and the horse for $500, thus

x + y = 500        [1]

The cow was sold at a profit of 10%, thus:

Sale price of the cow= 1.1x

The horse was sold at a loss of 10%, thus:

Sale price of the horse= 0.9y

The total operation was a 2% loss, i.e. 0.98*500=490. Thus, we have:

1.1x + 0.9y = 490        [2]

From [1]:

y = 500 - x

Substituting in [2]:

1.1x + 0.9(500 - x) = 490

Operating:

1.1x + 450 - 0.9x = 490

0.2x = 490 - 450 = 40

x = 40/0.2

x = 200

The man paid $200 for the cow

A patient has a twenty-centimeter incision along the abdomen that must have a topical antibiotic ointment applied for every dres
rodikova [14]

Answer:

The amount of medication to be applied is approximately 7.87 inches

Step-by-step explanation:

The given parameters are;

The length of the incision the patient has = 20 cm

The length of the application of the antibiotic = The length of the incision the patient has

∴ The length of the application of the antibiotic = 20 cm

The amount of medication to be applied = 20 cm = 7.874016 inches ≈ 7.87 inches
