Suppose a one-year subscription to a magazine costs $12.99 and a three-year subscription costs $25.98. The cost and length of a subscription are related. Write a slope-intercept equation to model the cost of a subscription for any period of time.
Answers
Answer:
[tex]y = 6.495x + 6.495[/tex]
Step-by-step explanation:
Represent years with x and cost with y.
So, we have:
[tex](x_1,y_1)=(1,12.99)[/tex]
[tex](x_2,y_2)=(3,25.98)[/tex]
Required
Determine the slope intercept equation
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{25.98 - 12.99}{3 - 1}[/tex]
[tex]m = \frac{12.99}{2}[/tex]
[tex]m = 6.495[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = 6.495[/tex]
[tex](x_1,y_1)=(1,12.99)[/tex]
[tex]y - 12.99 = 6.495(x - 1)[/tex]
[tex]y - 12.99 = 6.495x - 6.495[/tex]
Make y the subject
[tex]y = 6.495x - 6.495 + 12.99[/tex]
[tex]y = 6.495x + 6.495[/tex]

A device produces random 64-bit integers at a rate of one billion per second. After how many years of running is it unavoidable that the device produces an output for the second time? Round to the nearest number of years.
Answers
Answer:
3171 × 10^(44) years
Step-by-step explanation:
For each bit, since we are looking how many years of running it is unavoidable that the device produces an output for the second time, the possible integers are from 0 to 9. This is 10 possible integers for each bit.
Thus, total number of possible 64 bit integers = 10^(64) integers
Now, we are told that the device produces random integers at a rate of one billion per second (10^(9) billion per second)
Let's calculate how many it can produce in a year.
1 year = 365 × 24 × 60 × 60 seconds = 31,536,000 seconds
Thus, per year it will produce;
(10^(9) billion per second) × 31,536,000 seconds = 3.1536 × 10^(16)
Thus;
Number of years of running is it unavoidable that the device produces an output for the second time is;
(10^(64))/(3.1536 × 10^(16)) = 3171 × 10^(44) years

A (6,5)
B (-6,-5)
C (5,6)
D (-5, -6)
Answers
Answer:
x = 6, y = 5
Step-by-step explanation:
Solve the following system:
{5 y - 6 x = -11 | (equation 1)
{-11 y + 6 x = -19 | (equation 2)
Add equation 1 to equation 2:
{-(6 x) + 5 y = -11 | (equation 1)
{0 x - 6 y = -30 | (equation 2)
Divide equation 2 by -6:
{-(6 x) + 5 y = -11 | (equation 1)
{0 x + y = 5 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{-(6 x) + 0 y = -36 | (equation 1)
{0 x + y = 5 | (equation 2)
Divide equation 1 by -6:
{x + 0 y = 6 | (equation 1)
{0 x + y = 5 | (equation 2)
Collect results:
Answer: {x = 6, y = 5
Two dice are rolled; find the probability for total: a) 1, b) 4 or 6; c) <13
Answers
Answer:
0 ; 2/9 ; 1
Step-by-step explanation:
In a roll of two dice ;
The sample space = (Number of faces on die)^number of dice rolled = 6^2 = 36
The total possible outcome = sample space = 36
The probability of an event (A) :
P(A) = number of required outcome / number of total possible outcomes
find the probability for total: a) 1,
P(total of 1)
Number of 1 total = 0
Hence, P(total of 1) = 0
b) 4 or 6;
Number of 4 total = 3
Number of 6 total = 5
3 /36 + 5 / 36 = 8/36 = 2/9
c) <13
P(total < 13)
Number of total < 13 = 36
36 / 36 = 1

A rectangular-shaped parking lot is to have a perimeter of 546 yards. If the width must be 61 yards because of a building code, what will the length need to be?
Answers
The length of the parking lot will be 212 yards
Perimeter of rectangleFrom the question, we are to determine what the length of the parking lot needs to be
From the given information, we have that
"A rectangular-shaped parking lot is to have a perimeter of 546 yards"
and
"the width must be 61 yards"
From the formula for perimeter of a rectangle,
P = 2(l +w)
Where P is the perimeter
l is the length
and w is the width
From the given information,
P = 546 yards
w = 61 yards
Putting the parameters into the equation,
546 = 2(l + 61)
546 = 2l + 122
2l = 546 - 122
2l = 424
l = 424/2
l = 212 yards
Hence, the length of the parking lot will be 212 yards

a) Work out the cost of 100g of each type of tea
b) Which type of tea is the cheapest?
Answers
Answer:
The cheapest is the Kenyan tea which costs £1.05 for each 100g.
Step-by-step explanation:
A)
200 g of Kenyan tea costs £2.10
1. Calculate the rate of each gram, by dividing 2.10/200
0.0105 x 100 = £1.05 for each 100g
300 g of Columbian tea costs £3.45
1. Calculate the rate of each gram, by dividing 3.45/300
0.0115 x 100 = £1.15 for each 100g
1. Calculate the rate of each gram, by dividing 1.70/150
150 g of Indian tea costs £1.70
0.01133333333 x 100 = £1.133333333 for each 100g

A card is selected at random from an ordinary deck of 52 cards. What is the probability that it is either an ace or a spade
Answers
Answer: 4/13
Step-by-step explanation:
Number of cards in a deck = 52
Number of spades = 13
Number of aces = 4
Number of ace of spade = 1
Probability of either a spade or an ace :
P(spade or ace) = P(spade U ace)
P(spade U ace) = p(spade) + p(ace) - p(spade n ace)
Probability = required outcome / Total possible outcomes
P(spade) = 13 / 52
P(ace) = 4 / 52
P(spade n ace) = 1 / 52
P(spade U ace) = p(spade) + p(ace) - p(spade n ace)
= 13/52 + 4/52 - 1/52
= 16 / 52 = 4 /13
(7y-8y)2+14=2 solve for x
Answers
Answer:
y = 6
Step-by-step explanation:
(7y-8y)2+14=2
First, simplify the left side
7y - 8y = -y
2*-y = -2y
Now solve the equation
-2y + 14 = 2
Subtract 14 from both sides
-2y = -12
Take away the negative signs since both sides are negative
2y = 12
Divide both sides by 2
y = 6
(If the variable was x instead of y the variable would still equal 6)

Does the rule y = 6x7 represent an exponential function?
yes
no
Answers
No , the rule y = 6x ^7 does not represent an exponential function.
The exponential function is a mathematical function of the form f(x) = a^x. where "x" is a variable and "a" is a constant called the base of the function, which must be greater than 0. The exponential function is defined by the formula f(x) = a^x. where the input variable x is displayed as an exponent. An exponential curve depends on the exponential function and the value of x.
We have given y =6 x^7.
Here the variable is base & the exponent is an integer.
But an exponential function has a constant as its base and a variable as its exponent .
So, it does not represent an exponential function .

In the 1936 Olympics, Jesse Owens won a gold medal for running the 100-meter dash in 10.3 seconds. What was Owens' speed in meters per second, rounded to the nearest tenth?
Answers
Jesse Owen speed is 9.71 meters per seconds.
How to find speed?Speed is a scalar quantity that refers to "how fast an object is moving.
In other words, speed is the distance travelled per unit of time.
Therefore, it can be represented mathematically as follows:
speed = distance / time
Jesse Owen covers 100 meters dash for 10.3 seconds. Therefore, the speed he used for the race can be calculated as follows:
speed = distance / time
distance = 100 meters
time = 10.3 seconds
Hence,
speed = 100 / 10.3
speed = 9.70873786408
speed = 9.71 meters per seconds
Therefore, Jesse Owen speed is 9.71 meters per seconds.
