If the sum of their ages is 60, Bao's age is 18.

To find Bao's age, we need to use the information given in the question about the ages of the siblings and the sum of their ages. Let's start by assigning a variable to represent the youngest sibling's age. We'll call this x.

Since the ages are consecutive even integers, we know that the next sibling's age is x + 2, the third sibling's age is x + 4, and Bao's age is x + 6.

Now we can use the information about the sum of their ages to create an equation:

x + (x + 2) + (x + 4) + (x + 6) = 60

Simplifying this equation gives us: 4x + 12 = 60

Subtracting 12 from both sides gives us:

4x = 48

And finally, dividing by 4 gives us:

x = 12

So the youngest sibling is 12 years old. To find Bao's age, we need to add 6 to this value: 12 + 6 = 18

Therefore, Bao's age is 18.

Explanation:

Calculator with inverse tangent is a calculator with  four basic arithmetic operations and variety of functions such as logarithms, exponents, trigonometric functions etc.

A calculator with inverse tangent, commonly known as a scientific calculator, is a type of electronic calculator designed to perform mathematical calculations beyond basic arithmetic. In addition to the four basic arithmetic operations (addition, subtraction, multiplication, and division), it includes a variety of functions such as logarithms, exponents, trigonometric functions (sine, cosine, tangent), and their inverse functions (arcsine, arccosine, and arctangent).

The inverse tangent function, also known as arctangent, is one of the trigonometric functions that is commonly included in scientific calculators. It is used to determine the angle between the x-axis and a line drawn between the origin and a point on the graph of a function. In other words, it helps to find the angle whose tangent is a given number.

To use the inverse tangent function on a calculator, you will typically need to press the "tan^-1" or "arctan" button, followed by the number you want to find the arctangent of. The calculator will then display the angle in radians or degrees, depending on the mode it is set to.

Answer:

Step-by-step explanation:

To find out how many times greater the population of Chicago is than Austin, we can divide the population of Chicago by the population of Austin:

Population of Chicago / Population of Austin = 2,720,546 / 900,000

Simplifying the expression by dividing both the numerator and denominator by 100,000, we get:

Population of Chicago / Population of Austin = 27.20546 / 9

Dividing these numbers, we get:

Population of Chicago / Population of Austin = 3.022838

Therefore, the population of Chicago is about 3 times greater than the population of Austin.

The number [square] can divided exactly by six. and when [square] is divided by five, four is the number left over is:

12, 42, 72 o 102

The number [square] can be represented as 6x, where x is any positive integer, since it can be divided exactly by six. When [square] is divided by five, four is the number left over. Therefore, we can write the equation:

6x = 5y + 4

Where y is any positive integer. We can rearrange the equation to solve for x:

6x - 4 = 5y

2x - 2 = (5/3)y

2x - 2 = (5/3)(3x/5)

2x - 2 = (15/15)x

2x - 2 = x

x = 2

Therefore, the smallest possible value for [square] is 6(2) = 12. The next smallest possible value for [square] would be 6(2 + 5) = 42, since adding multiples of 5 to x will still satisfy the equation. The possible values for [square] are 12, 42, 72, 102, etc.

There were approximately 1522 public electric charging units available in 2007.

There were approximately 9894 public electric charging units available in 2009.

There were approximately 25230 public electric charging units available in 2010.

The formula for an exponential function is [tex]f(x) = a^x,[/tex]where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The exponential function is [tex]A(t) = 234(2.55)^t.[/tex]

Use the formula [tex]A(t) = 234(2.55)^t[/tex] to find the number of public electric charging units available for hybrid vehicles in a given year.

To find the number of outlets available in 2007, substitute t = 2 (since 2007 is two years after 2005) into the formula -

[tex]A(2) = 234(2.55)^2[/tex]

A(2) = 234(6.5025)

A(2) ≈ 1521.59

Therefore, the number of electric vehicles is 1522.

To find the number of outlets available in 2009, substitute t = 4 (since 2009 is four years after 2005) into the formula -

[tex]A(4) = 234(2.55)^4[/tex]

A(4) = 234(42.2825062)

A(4) ≈ 9894.10

[tex]A(5) = 234(2.55)^5[/tex]

A(5) = 234(107.820391)

A(5) ≈ 25229.97

The value of p(10) we get as  123.

What is Quadratic polynomial ?

A quadratic polynomial is a polynomial of degree 2, which means that it is a polynomial expression in one variable (usually written as x) that contains only terms of the form ax² + bx + c, where a, b, and c are constants. The highest exponent of the variable x in a quadratic polynomial is 2.

We are given a table of values for the quadratic polynomial p. Since p is a quadratic polynomial, it can be written in the form:

p(x) = ax² + bx + c

where a, b, and c are constants.

To find the value of p(10), we need to substitute x = 10 in the above equation and simplify:

p(10) = a(10)² + b(10) + c

p(10) = 100a + 10b + c

We don't know the values of a, b, and c, but we can use the values in the table to set up a system of equations.

From the table, we can see that:

p(0) = c = 3

p(1) = a + b + c = 6

p(2) = 4a + 2b + c = 11

Solving this system of equations, we get:

a = 1

b = 2

c = 3

Therefore, the quadratic polynomial p is:

p(x) = x² + 2x + 3

To find p(10), we substitute x = 10 in the above equation:

p(10) = (10)² + 2(10) + 3

p(10) = 100 + 20 + 3

p(10) = 123

Therefore, the value of p(10) is 123.

Points for Elephant powerful. When we remove the point for elephant, the slope line will drop, and we shouldn't just keep eliminating animals.

a) The link between gestation lengths and life expectancies would seem larger if the point for elephants in the scatterplot's upper right corner were removed. This is due to the elephant data point's status as an outlier, which means that it differs significantly from the scatterplot's other points and can significantly affect the regression line.

b) If the elephant point is eliminated, the slope of the line will decrease. This is due to the elephant point's long gestation time and long life span, which contribute to the regression line's greater slope.

c) No, we shouldn't keep eliminating creatures to make the model more robust. While the strength of the link between the variables can be strengthened by deleting outliers like the elephant point, it's critical to remember that each data point reflects a genuine observation.

d) Elephants undoubtedly had some influence. The elephant point had a considerable impact on the link between gestation times and life expectancies, as shown by the fact that deleting it resulted in a reduction in the slope of the regression line.

Step-by-step explanation:

x² + 5 = 86 ( subtract 5 from both sides )

x² = 81 ( take the square root of both sides )

x = ± [tex]\sqrt{81}[/tex] = ± 9

To solve the equation x^2 + 5 = 86, we need to isolate the variable x on one side of the equation. We can do this by performing the opposite operations on each side of the equation.

   Subtract 5 from both sides of the equation:

   x^2 = 81

   Take the square root of both sides of the equation:

   x = ±9

Therefore, the solutions to the equation x^2 + 5 = 86 are x = 9 and x = -9.

Yes, 23 is a prime number, because its only factors are 1 and itself.

Answer:

Step-by-step explanation:

The statement "x = y² - 9" is not a function because for some values of y, there are multiple corresponding values of x.

A relation between a set of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).

Now in the given question ,

In particular, when y = 3, there are two possible values of x (x = 0 and x = 6), so (3, 0) and (3, 6) are two points on the graph of this equation. This violates the definition of a function, which states that for each input (in this case, y), there can only be one output (x). The other statements are not relevant to determining whether the equation is a function.
