From the chart, estimate (roughly) the number of transistors per IC in 2016. Using your estimate and Moore's Law, what would you predict the number of transistors per IC to be in 2040?
Please explain
The estimates for the number of transistors per IC, using an exponential function, are given as follows:
2016: 16,777,216,000.2040: 6.87 x 10¹³.What is the format of an exponential function?An exponential function has the general format presented as follows:
[tex]y = ab^\frac{x}{n}[/tex]
In which the parameters of the function are listed as follows:
a is the initial value of the function.b is the rate of change of the function.n is the period relative to the rate of change.By Moore's Law, the number of transistors per IC doubles every two years, hence the values of parameters b and n are both two, that is:
b = 2, n = 2.
We take 1972 as the reference year, when the amount was of 4000 transistors per IC, hence the value of parameter a is given as follows:
a = 4000.
Thus the equation is:
[tex]A(t) = 4000(2)^{\frac{t}{2}}[/tex]
Giving the number of transistors per IC in t years after the reference year of 1972.
2016 was 44 years after 1972, hence the estimate for the amount of transistors by IC was of:
[tex]A(44) = 4000(2)^{\frac{44}{2}} = 16,777,216,000[/tex]
2040 will be 68 years after 1972, hence the estimate for the amount of transistors by IC is of:
[tex]A(68) = 4000(2)^{\frac{68}{2}} = 6.87 \times 10^{13}[/tex]

Answer: 114
Step-by-step explanation:
firstly, convert meters to centimeters:
2.5m * 100cm in a meter = 250 cm
let the length of the first shelf equal x:
250 = x + (2x + 18) + (x - 12) + (x + 4)
combine like terms:
250 = 5x + ( 18 - 12 + 4) = 5x +10
subtract 10 from both sides:
240 = 5x, then solve for x
240/5 = x
x = 48 cm
the length of the second shelf was 2x + 18, so plug in 48 for x:
2(48) + 18 = 114
Answer:
114 [cm].
Step-by-step explanation:
1) if the length of the 1st shelf is 'x', then
2) the length of the 2d shelf is '2x+18', the 3d shelf is 'x-12' and the 4th shelf is 'x+4';
3) the sum of the all 4 shelves is 250 [cm], then it is possible to make up the equation:
x+(2x+18)+(x-12)+(x+4)=250;
4) the root of the equation above is x=48, then
5) the required length of the 2d shelf is 2*48+18=114 [cm].

An bucket starts with 872 gallons of water and is emptying at a rate of 19 gallons per hour. If I know that the bucket has 8 gallons of water, how long has it been emptying?
Answer:
45.47368421 (round as much as you need)
Step-by-step explanation:
We can model the equation using G(h) = -19h + 872, where -19 is the rate at which the bucket is emptying and 872 is the amount of gallons the bucket starts with.
Since gallons is the output, we would have 8 = -19h + 872 and we simply need to solve for h
[tex](8 = -19h+872)-872\\\frac{(-864=-19h)}{-19} \\h=45.47368421[/tex]

Step-by-step explanation:
The Pythagorean theorem states "a^2 + b^2 = c^2", where "a" and "b" are the legs, while "c" is the hypotenuse.
Knowing this, we can substitute each variable with given values on the triangles
1. "4" and "8" are legs "a" and "b" and we need to find the hypotenuse "c"
4^2 + 8^2 = c^2
16 + 64 = c^2
80 = c^2
√80 = c
4√5 = c
2. "6" and "3" are legs "a" and "b" and we need to find the hypotenuse "c"
6^2 + 3^2= c^2
36 + 9 = c^2
45 = c^2
√45 = c
3√5 = c
3. "7" and "10" are legs "a" and "b" and we need to find the hypotenuse "c"
7^2 + 10^2 = c^2
49 + 100 = c^2
149 = c^2
√149 = c
4. "3" and "7" are legs "a" and "b" and we need to find hypotenuse "c"
3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
√58 = c

The revenue for a business, as a function of units produced, x, is shown below by R(x). C(x) represents the cost of producing x units. Calculate the profit function and then determine how many units must be produced for the business to break even.
R(x) = 24x
C(x) = 17x + 161
By calculating profit function to break even, the company needs to produce 23 units.
What is meant by profit function?The amount received when a good or service is sold for a price is referred to as revenue. The cost of a product or service is the amount spent on its sale. Profit is defined as the difference between revenue and costs. A profit function is a relationship that shows the difference between the cost and revenue functions. The graph of a profit function can show the best combination of revenue and costs to produce the most profit. This is known as optimization.
Profit is defined as revenue less costs. This means that there is a profit function, P(x).
P(x) = R(x) - C(x)
Breaking even is the point at which revenue begins to exceed costs. It is thus the point at which P(x) = 0. Because these are all linear functions, you know that the business will be profitable after that point.
P(x) = 0
R(x) - C(x) = 0
R(x) = 24x
C(x) = 17x + 161
From the above equation,
R(x)=C(x)
24x=17x+161
7x=161
x=161/7
x=23
For the company to break even, 23 units must be produced.

Write an equation for a line parallel to y=-4x+3 and passing through the point (4, -20)
The equation of the line is y = -4x -4.
We need to calculate the line which is parallel to y = -4x +3 and passes through the point (4, -20)
The given equation is y = -4x +3
Comparing this equation with the general equation of the line, y = mx +c, we get the slope of the equation is -4.
Now, When two lines are parallel to each other, their slopes are equal.
So, the slope of the required equation is -4.
Now, the equation of the line which passes through the points, [tex](x_{1} ,y_{1} )[/tex] and has slope m, is given by
[tex]y - y_{1} = m(x-x_{1} )[/tex]
Putting the values in the general equation, we get,
y - (-20) = -4(x - 4 )
y + 20 = -4x +16

Given a standard deck of playing cards, what is the probability of drawing each hand:
2 diamonds
1 diamond and 1 heart
Explain why the more likely outcome, above, is more likely
The probability of drawing 2 Diamonds is 1/17.
The probability of drawing 1 diamond and 1 heart is 13/204.
How to find probability for a deck of cards?
In total there are 52 cards in a deck.these 52 cards are divided in 4 suits each having 13 card values.The 4 suits are: Clubs, Spades, Diamonds and Hearts.13 card values are: 2-10, King, Queen, Jack and an AceKing, Queen and Jack are called Face cards.For finding probability of chosen cards to cases arise: 1. With replacement of the drawn card; 2. Without replacement of the drawn cardAccording to the given question:
Since there are 52 cards, the probability of getting a diamond in the first draw is 13/52.
After the first card is drawn, there are just 12 diamonds left.
So, the probability of drawing the diamond now is 12/51.
The total probability is the product of two probabilities
So, P = 13/52 x 12/51 = 1/4 x 4/17
P = 1/17 ≈ 0.058
So the probability of drawing 2 Diamonds is 1/17.
Similarly, we know probability of getting a diamond in first is 13/52.
Also the probability of drawing a heart from 51 cards is 13/51.
The total probability P = 13/52 x 13/51
P = 1/4 x 13/51
P = 13/204 ≈ 0.063
So the probability of drawing 1 diamond and 1 heart is 13/204.
More likely outcome is the one whose probability is closer to unity. Since 13/204 > 1/17 that is 0.063 > 0.058 therefore drawing a heart and a diamond is a more likely outcome.
