4. On August 16, 2012, the population of humans on Earth was estimated at 7,060,268,214. What is this number rounded to the nearest hundred million?
According to estimates, there were 7,060,268,214 people on Earth as of August 16, 2012. Rounding to the nearest hundred million, 7,060,268,214 equals 7,100,000,000.
How do you round to the nearest hundred million?Find the digit that is 100,000,000 places away first. The next step is to check if the number that comes after the hundred million place is 5 or higher. Next, multiply the result by 100 million to the nearest billion. 200,000,000 is the reply. 4,000,000 or 5,000,000 may be the million closest to you.
Take a glance at the number in the right-hand column, the hundred thousands, to determine the nearest million. 5 appears in the column for "hundred thousands." It is standard practise to round up numbers that are five or more. This means that you should look at the digit in the ten thousand spot to round numbers out to the nearest hundred thousand. 1,000,000 is added as a rounding error.

Help the perimeter is about _ units_
The perimeter of the given polygon is about 16.4 units.
How to find the perimeter of the polygon?We want to find the perimeter of the polygon whose vertices are (-3, 2), (2, 2) and (-1, -3).
The perimeter will be equal to the sum of the distances between the vertices, and remember that the distance between two points (x₁, y₁) and (x₂, y₂) is:
d = √( (x₂ - x₁)² + (y₂ - y₁)²)
The distances are:
between (-3, 2) and (2, 2)
d = √( (-3 - 2)² + (2 - 2)²) = 5
between (-1, -3) and (2, 2)
d = √( (-1 - 2)² + (-3 - 2)²)
d = √( 9 + 25) = 6
between (-1, -3) and (-3, 2)
d = √( (-1 + 3)² + (-3 - 2)²)
d = √29 = 5.4

Write a function in terms of t that represents the situation.
A $900 sound system decreases in value by 9% each year.
y=
Answer:
y = 900(0.91^t)
Step-by-step explanation:
You want a function that describes the value of a $900 sound system that decreases in value by 9% per year.
Exponential functionWhen the amount of change is proportional to the amount, the amount is described by an exponential function:
y = ab^x
where 'a' is the initial value, and 'b' is the "growth factor."
ApplicationHere, the change is expressed as a "growth rate" of -9% per year. The growth factor is 1 added to the growth rate:
b = 1 +(-9%) = 1 -0.09 = 0.91
The initial value is given as ...
a = 900
So the function you want is ...
y = 900(0.91^t)
__
Additional comment
The independent variable in this case is time, and the problem statement tells you to use 't' to represent it. The decay rate is given as a percentage per year, so the units of t will be years.
Ricardo has an equally likely chance of spinning an odd number as spinning a number less than 4
The given statement that " Ricardo has an equally likely chance of spinning an odd number as spinning a number less than 4" is True.
How to find the probability?When rolling a fair dice, the probability of getting an odd number is:
= Number of odd numbers / Number of sides on die
Number of odd numbers = 1, 3, 5
Probability of odd number:
= 3 / 6
= 1 / 2
Probability of number less than 4 :
= 3 / 6
= 1 / 2

True FalseWhat is value of sin?.
Let's first review the Sin function before talking about Sin 0. Therefore Sin 0 value is 0.
The Sine, Cosine, and Tangent functions in trigonometry are used to determine the angles and length of a right-angled triangle, respectively.
The relationship between the angle, perpendicular side, and hypotenuse side is defined by the sine function.
Alternatively, you can use sin theta, which is equal to the right-angled triangle's perpendicular to hypotenuse ratio. Sin theta is the angle produced between the hypotenuse and adjacent side.
Definition Of Sin In Relation To Sin 0.
Sin 0 denotes that (x,y) is where the value of the x coordinate is 1, and the value of the y coordinate is 0. (1,0). In this case, the hypotenuse has a value of 1, and the opposing side or perpendicular has a value of 0.
As a result, if we set the numbers in the sin ratio for = 0, the perpendicular side to be 1, and the hypotenuse to be 0, we obtain,
Sin 0 = 0/1
Sin 0 = 0

How do you prove log2 7 is irrational?.
The log₂(7) is irrational, because if we assume that it is rational, we can reach a contradiction.
Assume that log₂(7) is rational. This means that it can be written as the ratio of two integers, a/b, where a and b are integers and b is not equal to zero.
Then, using the definition of a logarithm, we have: 2^(a/b) = 7
Multiply both sides by b, we have: 2^a = 7b
Now we have a problem, because 7b is not necessarily a power of 2. This means that our assumption that log₂(7) is rational leads to a contradiction, and therefore log₂(7) must be irrational.

In the production range of 2 to 3 combs, the opportunity cost of producing one more comb is d) 0.14 brushes.
Explain about production range refer to:Opportunity cost is the cost of one choice in terms of the best alternative foregone. In this case, the opportunity cost of producing one more comb is the number of brushes that have to be given up in order to produce that additional comb.For example, if the country X is currently producing 2 combs, in order to produce one more comb, 0.14 brushes would have to be given up. This means that for every additional comb produced, 0.14 brushes would have to be sacrificed. This trade-off is reflected in Table 1.3 and is the opportunity cost of producing one more comb in the production range of 2 to 3 combs.In other words, the opportunity cost of producing one more comb is the number of brushes that would have to be sacrificed in order to produce that comb.

any negative exponent of 1.3 means we have to consider it as 1/1.3 with the positive exponent.
so, if the given temperature (x) is negative, 1.3 has a positive exponent and gets bigger and bigger the lower (smaller) x gets.
if the given temperature (x) is positive, 1.3 has a negative exponent and gets smaller and smaller the higher (bigger) x gets.
the domain is the interval or set of all valid x-values.
there is no need for any restriction for x.
so, the domain is all real numbers.
the question is : up to what temperature will there be heating ?
at 5°C ? yes, sure.
at 10°C ? yes, sure.
at 15°C ? some people still need heating.
at 20°C ? most likely not.
but f(20) = $0.042094266... ≈ $0.04
so, still a tiny little bit of heating is happening for the function, but in reality most likely not at all.
the information about such a limit is missing in the question. so, again no limit for x.
f(-8) means that x = -8.
f(-8) = 8(1.3)^--8 = 8(1.3)⁸ = 8×8.15730721 =

Step by step explanation please?!
Using simultaneous equations, the cost of one slice of pizza bought by Max's dad at the concession stand is $1.75.
What are simultaneous equations?Simultaneous equations are two or more equations solved concurrently or simultaneously.
Simultaneous equations are also called a system of equations.
Bottles Slices of Total
of Water Pizza Cost
1st purchase 5 8 $20.25
2nd purchase 1 3 $6.50
Let the cost of bottles of water = b and the cost of slices of pizza = p
Equations:Equation 1: 5b + 8p = 20.25
Equation 2: b + 3p = 6.50
Multiply Equation 2 by 5:
Equation 3: 5b + 15p = 32.50
Subtract Equation 1 from Equation 3:
5b + 15p = 32.50
-
5b + 8p = 20.25
7p = 12.25
p = 1.75
The cost of one slice of pizza (p) = $1.75
Check:
b + 3p = 6.50
b + 3(1.75) = 6.50
b + 5.25 = 6.50
b = 1.25
= $1.25
Thus, the cost of one slice of pizza is $1.75.
