Answer:

An equation in function notation for the total cost of the book  club will be:

  • y = 20x + 12

Step-by-step explanation:

Given that Genesis needs to pay $12.00 for entrance into the book club.

Per month fee = $20.00

We know that the slope-intercept form of a linear function is

y = mx+b

where m is the slope and b is the y-intercept

As the rate of change is also called the slope.

The rate of $20.00 per month would be termed as the slope = m = 20

One time fee = $12.00, meaning the y-intercept = b = 12

Thus, the equation becomes

y = mx+b

  • y represents the total cost
  • x represents the duration
  • m represents the rate of change = m = 20
  • b represents the y-intercept = b = 12

y = 20x + 12

Therefore, an equation in function notation for the total cost of the book  club will be:

  • y = 20x + 12

A group walked 3/8 mile in 1/5 hour. Which is the groups walking speed in miles per hour
gogolik [260]

Answer:

The groups walking speed is 1\frac{7}{8}\frac{miles}{hour}  or 1.875\frac{miles}{hour}

Step-by-step explanation:

we know that

To find the speed divide the distance by the time

so

\frac{(3/8)}{(1/5)}=\frac{15}{8}\frac{miles}{hour}

Convert to mixed number

\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\frac{miles}{hour}

The price of a computer component is decreasing at a rate of 15% per year.
Alex_Xolod [135]

Answer:

  • exponential
  • $30.71

Step-by-step explanation:

Usually, this wording means the decrease is proportional to the current price, characteristic of an exponential function.

__

The decay factor is 1-(decay rate), so is 1-0.15 = 0.85. After 3 years, the value has been multiplied by this factor 3 times:

  $50×0.85³ ≈ $30.71 . . . . cost in 3 years

_____

<em>Comment on percent per year</em>

Less often, the indicated decrease is intended to be <em>that percentage of the original price</em>. The result is that the price decreases by a constant amount each year, a linear decrease. This condition most often arises in conjunction with figuring depreciation in value for tax or accounting purposes.

The upshot is that you always need to be careful to understand what the base of a percentage is intended to be.

4 letters are typed, with repetition allowed. What is the probability that all 4 will be vowels? Write your answer as apercent.
zubka84 [21]

The total number of alphabets are 26.

The total number of vowels are 5.

Th repetition is allowed.

The possible outocme for all to be vowels are,

PO=5^4PO=625

The total outcome is,

TO=26^4

Therefore, the probability that all 4 will be vowels ,

P=\frac{625}{456976}P=0.00137

The probability is 0.137 %.
