Answers

Answer 1
Answer: The given formula is the Effective Annual Percentage rate formula where i signifies the nominal interest in terms of month. This formula is used in converting nominal interest rate to an effective interest rate since nominal interest rates are hard to compare unless their period are on the same basis.

Connor went to New York for vacation. He spent 3 nights at a hotel and rented a car for 4 days. Jillian stayed at the same hotel, but spent 4 nights and rented a car for 5 days from the same company. If Connor paid $675 and Jillian paid $875, how much did one night at the hotel cost?

Answers

The answer for the question in problem would be $125 is the price of hotel per night. This is computed by establishing the equations from the given statements, 3x + 4y = 625 and 4x +5y = 875. And by substitution you would get the answer of 125 as the price per night n the hotel and 75 per day for the rental of car.

Answer:

The cost of one night at the hotel is $125

Step-by-step explanation:

Let the cost of each night spend in hotel is = $x

Let the cost of each day of car rented = $y

Cannor spent 3 nights at a hotel and rented a car for 4 days paid $675.

\Rightarrow3x+4y=675  ......(1)

Jillian also spent 4 nights in same hotel and rented a car for 5 days paid $875.

\Rightarrow4x+5y=875  .......(2)

Now, we solve equation (1) and (2) by substitution method

From (1) take the value of x,  x=(675-4y)/(3)

then put in equation (2)4*(675-4y)/(3)+5y=875

solve,

\Rightarrow 4*(675-4y)+5y*3=875*3  (Taking LCM)

\Rightarrow2700-16y+15y=2625

\Rightarrow y=2700-2625=75

Now, put value of y=75 in value of  x=(675-4y)/(3)

\Rightarrow x=(675-4(75))/(3)

\Rightarrow x=(675-300)/(3)

\Rightarrow x=(375)/(3)

\Rightarrow x=125

Therefore, the cost of one night at the hotel is $125

400 = (L+30) X w

400 = 10+30 x 10  ( just b/c I can see 40 x 10  would be 400, calculus could also figure this out for us, but... that would be the minimum fencing he needs to buy and this questions isn't asking that, just make it fit on the back of his house, which we are not given, so just make up something, I used 10 b/c it was convenient )

400 = 40 x 10

2 sides are 40 , and one side is 10

so 90' of fence is needed

 

Exponential functions exhibit exponential growth (or decay). What does this mean to the graphs of these functions? a.. the graph will rise or fall more dramatically than a polynomial graph. c.. the graphs represent the population of bacteria in your mouth. b.. the graph is three dimensional. d.. the exponent in the equation is less than one

Answers

Answer:

The correct option is:

Option: a

a. the graph will rise or fall more dramatically than a polynomial graph.

Step-by-step explanation:

The most basic exponential function is a function of the form  

y=b^x

where   b  is a positive number.

When   b>1

the function grows in a manner that is proportional to its original value. This is called exponential growth.

When  0>b>1

the function decays in a manner that is proportional to its original value. This is called exponential decay.

The graph of a exponential function increases or decreases rapidly as compared to a graph of a polynomial function.

Hence, option a is the correct answer.

What multiplies to 378 and adds to -51

Answers

Your answer would be -9 & -42. 

Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.

Hope this makes sense & helps you ! (:
