Answer:

x> -10

Step-by-step explanation:

For the function in the given case the constraint on domain can be written as  x ≥ 182. The correct option is (a).

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

Suppose the amount of money spent be x.

And, the number of food items be y.

Now, as per the question the function can be written as follows,

y = x/182

As the number of food items can only be positive integers, the values of x must be the multiples of 182.

Thus, the expression for the domain can be written as x ≥ 182.

Hence, the constraint on the domain is given as x ≥ 182.

2.42 x 10^4  = 24200

 24200

+ 23580

 47 780    or   4.778 x 10^4

The expected value of this game will be 1,784.75.

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

In a lottery game, a player picks six numbers from 1 to 28. Assuming the player matches each of the six numbers, they win 50,000 bucks. In any case, they lose $1.

Then the probability of winning (p) and losing (q) is given as,

p = 1 / 28

q = 27 / 28

Then the expected value is given as,

E(x) = 50,000 (1 / 28) - 1 (27 / 28)

E(x) = 1785.714 - 0.964

E(x) = 1,784.75

The expected value of this game will be 1,784.75.

The time needed for the account value to reach 11200 dollars is approximately 15.9 years.

Simple interest formula is expressed as;

A = P( 1 + rt )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given the data in the question;

Plug the given values into the above formula and solve for time t.

A = P( 1 + rt )

A/P = 1 + rt

( A/P - 1 ) = rt

t = ( A/P - 1 ) / r

t = ( $11200/$5400 - 1 ) / 6.75%

t = ( $11200/$5400 - 1 ) / 6.75/100

t = ( 56/27 - 1 ) / 0.0675

t = ( 29/27 ) / 0.0675

t = 15.9 years.

Answer:

Step-by-step explanation:

Let x be the number.

The square of the number is x2

Increased by twice the number means add 2x.

So your equation is :

X2 +2x = 48.

Can you take it from here?

The asked number is 12.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, When the square of a certain number is added to the number, the result is the same as when 48 is added to three times the number.

Let the number be x,

x²+x = 48X3 + x

x² = 144

The value of f(5) When a polynomial f(x) is divided by x -5 is 4

Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.

If f(x) has a remainder of 4 when divided by x - 5

Then it means that if f(x -5) = f(0)

x -5 = 0

x = 5

so if you substitute 5 into f(x) which is f(5) it will give 4

so therefore f(5) = 4

In conclusion f(5) is same as 4

The value of x for the triangle is equal to 17.32.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Calculate the perpendicular side for both triangles by using the Pythagorean theorem.

H² = P² + B²

Here, H is the hypotenuse, P is perpendicular and B is the base.

For the first triangle, the perpendicular is calculated as,

P² = x² - 10²......................................................1

For the second triangle, the perpendicular will be,

P² = ( 30² - x² ) - 20²  .......................................2

Equate the equation 1 and 2 and solve,

x² - 10² = ( 30² - x² ) - 20²

x² - 100 = 900 - x² - 400

2x² = 900 - 400 + 100

2x² = 600

Explanation:

A converted to standard notation is the same number.

The appropriate estimate for the diameter of the speck of dust is 2 × 10⁻⁵ inches. So the answer is option A, 2 × 10⁻⁵ in.

In scientific notation, numbers are written with the base 10 much like in decimal notation. Scientific notation is the term used when a number is expressed as the product of two numbers.

Where the first number is more than or equal to one but less than ten and the second number is the power of ten expressed in exponential form.

Step - 1 Move the decimal point up to the first number that is equal to 1 but less than 10.

Step - 2 Count the number of places that the point moved.

Step - 3 Now Write the resultant number as a product with a power of 10.            

Here we have

Diameter of a speck of duct = 0.00002 inches

Convert the given decimal into a scientific notation

As we learn above

Move the decimal point up to a whole number toward the right

=> 0.00002 = 2. = 2

Count the number of zeros or places moved

=> n = 5

Now write the number as a power of 10, Now write the above whole number part as the product of 10

=> 2 × 10⁻⁵     [ ∵ The power is moved right we need to use negative ]    

Therefore,

The appropriate estimate for the diameter of the speck of dust is 2 × 10⁻⁵ inches. So the answer is option A, 2 × 10⁻⁵ in.

where A is in million

t is years after 2000.

(a) We have to find the population in 2000.

The distance for Tucker to walk is 1 mile, only then both the donors would have the same amount. This was found using linear equations.

What are linear equations?

A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.

Since it's given that Tucker's mother will give flat $5. So let that be the RHS of the equation. Now his grandmother will give him $5 for every mile he walks.

Let that be 5x.

Now the equation would be: 5x=5

Which results in x=1.

Therefore at 1 mile, both of the donors' amounts would be the same.
