Mr. endres wants to put fencing around his rectangular shaped backyard. the width of the backyard is 42 feet and the length is t
Anna71 [15]

The the number of feet needed for the fence of the rectangular garden = its perimeter = 252 ft.

<h3>What is the Perimeter of a Rectangle?</h3>

Perimeter = 2(length + width).

The number of feet needed for the fence around the rectangular garden = perimeter of teh rectangular garden.

Given the following:

  • Width = 42 ft.
  • Length = 2(42) = 84 ft.

Plug the values into Perimeter = 2(length + width):

Perimeter of the rectangular garden = 2(42 + 84)

Perimeter of the rectangular garden = 252 ft

Therefore, the the number of feet needed for the fence of the rectangular garden = its perimeter = 252 ft.

Please hurry; Which function increases the fastest? A. y 5 14x B. y 5 23 · 17x C. y 5 120x D. y 5 2275x^x
Maurinko [17]

Answer: y = 14^x

Step-by-step explanation:

Here the options are:

a y = 14^x

b y = -3*(17)^x

c y = 120x

d y = -275x

to see which function increases the fastest (or which function is steeper) we need to look at the first derivations of each one of these, and see which one is larger for every value of x:

the derivations are:

a y = x*14^(x - 1)

b y = -x*3*(17)^(x  - 1)

c y = 120

d y = -275

So we can already discard options c and d, because have constant rate of change.

Then we keep options a and b.

Always when we have an exponential function, like a^x and b^x

The one with the larger base will be steeper.

So if a > b, then:

a^x is steeper than b^x

In this case, the function:

y = -3*(17)^x

has a larger base, but, this function is negative.

This means that as x increases, our function will decrease, then this function will not "increase the fastest" (because it does not increase)

Then the left option (a: y = 14^x)

Will be the correct one.

(this will happen after some value of x, because two of the options have constant derivatives, these may be steeper for smaller values of x, and as x increases, we will see that y = 14^x is the one that increases the fastest)

An exponential model shows the growth of a towns population in years. Identify the parts:
Semmy [17]

9514 1404 393

Answer:

  • 2% growth per year
  • 25,000 to start
  • 12 years
  • 31,706 currently

Step-by-step explanation:

The base of the exponent is (1 +0.02). The value 0.02 = 2% is the growth rate. It is positive, signifying a 2% rate of growth per year. (Negative values would mean decay.)

The number 25000 that multiplies the exponential term is the value of the expression when the exponent is zero. It represents the starting population.

The exponent is said to be in years, so the time is 12 years.

The current population is the value of the expression:

  25,000(1.02^12) ≈ 31,706 . . . . current population

Jeff has 50,670 miles on his truck. He drives 200 miles each week traveling to and from work. He plans on selling his truck afte
Natalka [10]
So the total is 75000 miles, so that is what the whole equation equals. So we start out with 75000=. Then, 200 is the number that is multiplied by the amount of weeks, so we then have 75000 = 200x. Finally, 50670 is the start, so we add it to the end. The final equation is 75000 = 200x + 50670.
