The nearest ten of 741 is 740.

The number system or the numeral system is the system of naming or representing numbers. We know that a number is a mathematical value that helps to count or measure objects and it helps in performing various mathematical calculations.

In mathematics, there are various number systems such as the decimal number system, binary number system, octal number system, and hexadecimal number system.

Round the number to the nearest ten. 741 is between 740 and 750.

Looking at the 1 in the one's place. It's less than 5, so round down to 740.

Thus, the nearest ten of 741 is 740.

Answer: x16/6

Step-by-step explanation:

The difference between exponential function and logarithmic function is their graph shows mirror image of each other.

A function of the form is a logarithmic function. It can be read as "y equals the log, base b, of x" or "y equals the log of x, base b." X > 0 and b > 0 and b 1 in both forms. y is not constrained in any way.

When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x. An essential mathematical function of the form is the exponential function. f(x) = a^x.

Examples of exponential functions include 2x, 10x, and ex; they have the form axe, where an is a constant. The cube root function, for example, "undoes" the cube function: 323=2. The logarithmic functions are the inverses of the exponential functions, that is, functions that "undo" the exponential functions.

log 7 can be approximated by using the common logarithm values of nearby integers.

log 7 = log 4 + log 2 + log (7/4)

log 2 = 0.3010

log (7/4) = 0.1403

log 7 = 0.6021 + 0.3010 + 0.1403 = 1.0434

To calculate the logarithm of 7 without a calculator, we can use the common logarithm values of nearby integers. First we determine the logarithm of 4, which is 0.6021. Then, the logarithm of 2 is 0.3010. Finally, the logarithm of the fraction 7/4 is 0.1403. We then add all of these together to get the logarithm of 7 which is 1.0434. Therefore, the logarithm of 7 is approximately 1.0434 when calculated without a calculator.

Domain = R or (-∞, ∞)

Range = R, because ∀ x ∈ R(Domain) y is also real.

How do you find the domain and range of f(x) =3x + 5

Clearly no real value of f(x) can make f(x) an imaginary value or value like ∞.

Domain = R or (-∞, ∞)

Range = R, because ∀ x ∈ R(Domain) y is also real.

As we observe, lines go off infinitely in both directions.

Therefore, the domain and range of this function are both set of reals or (-∞, ∞).

Example:

Suppose f(x) = 1/x

When x = 0, f(x) = 1/0 = infinity

Thus, the domain of f(x) cannot be R. Therefore, to define the domain the values of x which make f(x) = infinity are excluded from the set of reals.

Therefore the domain is R - {0}.

Answer: The zeros of the function f(x) = x^2 + 5x + 5 are given by the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 1, b = 5, and c = 5. Plugging these values into the formula, we get:

x = (-5 ± √(5^2 - 4(1)(5)))/2(1)

x = (-5 ± √(25 - 20))/2

x = (-5 ± √(5))/2

x = (-5 ± √5)/2

The zeros of the function are:

x = (-5 + √5)/2 and x = (-5 - √5)/2

in simplest radical form

x = (-5 + √5)/2 and x = (-5 - √5)/2

Step-by-step explanation:

The roots of the polynomial f(x) = x³ - x² - x - 15 are  3, -1 + 2i and -1 - 2i

A root of a polynomial is a value of x that makes the polynomial equal to zero. A polynomial is a mathematical expression that is made up of terms, each of which includes a variable (x) raised to a power, such as x^2, x^3, x^4, etc. The powers of x are called the degrees of the polynomial.

For example, the polynomial equation x^2 + 2x - 3 = 0 has two roots, x = -1 and x = 3.

The number of roots of a polynomial equation is determined by its degree. A polynomial equation of degree n has at most n roots. A polynomial equation of degree n can have n distinct roots, n-1 distinct roots, or even no roots at all.

f(x) = x³ - x² - x - 15

0 = x³ - x² - x - 15

Divide the first term of the dividend by the first term of the divisor to divide polynomials using long division.

Divide the dividend's first term by the divisor's first term to get the quotient's first term. Multiply the divisor by the quotient's first term and subtract the product from the dividend to get the remainder. This residual is now handled as a fresh dividend, but the divisor stays unchanged.

Polynomial division steps:

Step 1: Take the dividend's first term (x^2) and divide it by the divisor's first term to get the quotient's first term.

Step 2: In this situation, multiply the divisor(x - 2) by the answer(x), then insert the product beneath the dividend(x^2 + 2x + 3).

The range of the function f(x) = |x-1| is all non-negative real numbers from 0 to infinity.

The range of a function is all the possible values that can be outputted from the function. The range of the function f(x) = |x-1| is determined by looking at the expression and analyzing its behavior for different values of x.

When x is less than 1, the expression becomes negative and the absolute value makes the result positive. Therefore, for x less than 1, the result will be a positive number greater than 0. When x is equal to 1, the result is 0. When x is greater than 1, the expression is already positive, so the absolute value does not change the result.

This means that for x greater than 1, the result will also be a positive number greater than 0. Therefore, the range of the function f(x) = |x-1| is all non-negative real numbers from 0 to infinity.

{Complete question is

Which of the following expressions is equivalent to 8⋅8⋅8⋅8⋅8?}

Answer: The area of a rectangle is given by the formula: A = L x W

Where A is the area, L is the length and W is the width.

Given that the area of the rectangle is 32a^3b^4 square units, and the length is shown in the image, we can use the formula to find the width:

32a^3b^4 = L x W

To find the width, we need to divide both sides of the equation by L.

32a^3b^4 = L x W

W = 32a^3b^4 / L

As the length of the rectangle is given as 8a^2b^2, we can substitute it in the above equation to find the width of the rectangle

W = 32a^3b^4 / 8a^2b^2

W = 4ab^2

So the width of the rectangle is 4ab^2 square units.

We used the formula of the area of the rectangle and the given information of the area and length to find the width of the rectangle by isolating the width on one side of the equation.

In order to treat moderate to fairly severe pain, hydrocodone is used as an antitussive (cough suppressant) and narcotic analgesic. According to studies, hydrocodone is about equally effective to morphine for pain management and just as effective as codeine for suppressing coughs. Do not pack another person's medication in your bag, even if you are traveling together.

The name on the prescription for every drug you take should be your own; each person should stand on their own two feet in this situation. Since Percocet is a stronger opioid than Vicodin, it carries a higher risk of abuse than Vicodin. This is typical of stronger opioids.

We have, Miguel and his brother Ario are both deciding to a race.

Total length of pool = 25 meters

But they are standing 3 meters from one side of a 25-meter pool when both are decide to race.

So, the length of racing area = 25 - 3 = 22 meters.

Also, Miguel said that he will start when the ratio of Ario’s completed meters to Ario’s remaining meters is 1 : 4. Let us assume, the Ario’s completed meters be "x meters" . Then, Ario’s remaining meters = 22 - x

so, x : 22- x = 1 : 4

=> x/(22 - x) = 1/4

=> 4x = 22 - x

=> 5x = 22

=> x = 22/5 = 4.4

Distance is calculated using the formula distance=√(y2²-y1²)+(x2²-x1²).

A pair of numbers called coordinates are used to locate a point or a shape in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane. The term "ordinate" refers to a point's separation from the x-axis when scaled with the y-axis. Cord's are the collective noun for the abscissa and ordinate. The study of algebraic equations on graphs is known as coordinate geometry.
