How much greater is the intensity of an earthquake that measures 3 on the Richter scale than and earthquake that measures 1?.

The quadratic formula, factoring, using the square roots, and completing the square are the four methods for solving a quadratic equation.

The quadratic formula x = [-b(b2 - 4ac)] / (2a) provides the solutions of the quadratic equation ax2 + bx + c = 0. Therefore, to use the quadratic formula to solve a quadratic equation, simply transform the equation into its standard form, ax2 + bx + c = 0, and then apply the quadratic formula.

A quadratic equation is a second-order equation written as ax2 + bx + c = 0, where a is a real number and b and c are real number coefficients.

Answer:

Step-by-step explanation:

(a) 1.653 x 10^12 / 87 * 10^6

= (1.653 / 87) x (10^12 / 10^6)

= 0.019 x 10^6

= 1.9 x 10^4

or 19,000 days.

(b) 6 billion / 87 million

= 6,000,000,000 / 87,000,000

= 6000/87

= 69 days.

  The mathematical function known as a logarithm expresses the degree to which a base number must be raised in order to obtain a specific value. The symbol logb(x), where b is the logarithm's base and x is the value being evaluated, stands for the logarithm of a number. The natural logarithm, which has a base of e, is the most widely used logarithm (approximately 2.71828). The inverse function of exponentiation is the logarithm, according to this definition. The exponent to which we must raise b in order to obtain a number x is its logarithm to base b.

       It reads log2(3x + 8) = 5.

logb(a^n) = n * logb(a) where b is the base of the logarithm, is a property of logarithms that can be used to rewrite expressions. Since the base in this instance is 2, we obtain log2(3x + 8) = 5.

 corresponding to 2^5 = 3x + 8

Now that x is on one side of the equation, we can solve for it.

32 = 3x + 8

After deducting 8 from both sides, we arrive at 24 = 3x, which we then multiply both sides by to get 8

 Thus, x = 8 is the corresponding equation.

and the solution is 8.

     Therefore, the x=8 is the solution of this problem .

Step-by-step explanation:

Radical 3, also known as the cube root of 3, is a number that when multiplied by itself three times equals 3. It is denoted as ∛3. To find the value of radical 3, one way is to use a calculator with a cube root function.

Another way to find the value of radical 3 is to use a process called prime factorization. It involves breaking the number down into its prime factors and then taking the cube root of the result. In the case of ∛3, we have:

∛3 = ∛(3)

Since 3 is a prime number, we don't need to factor it further, and thus the cube root of 3 is just 3^(1/3) = 3^(1/3) = ∛3.

It's important to note that cube roots can be negative or positive and in this case, ∛3 is positive.

∛3 is an irrational number, which means that it cannot be expressed as a ratio of two integers, and its decimal representation is non-repeating and non-terminating. But it can be approximated to some decimal values.

The F-14 Tomcat was created as a long-range naval interceptor and air superiority fighter, allowing it to perform the roles of an escort attack aircraft when equipped with Sparrow missiles and a fleet air defense loitering interceptor when equipped with Phoenix missiles.

The F-14 was equipped with the capacity to shoot down ANY enemy aircraft, anywhere in the globe. No other Cold War aircraft could dispatch two nuggets on a "normal" mission from the CV and capture two Aces a few hours later. Incredible combat capabilities were made possible by the AIM-54 and the AWG-9.

During the war, the F-14 was credited with one air-to-air victory. On February 6, 1991, a VF-1 F-14A employing an AIM-9 Sidewinder brought down an Iraqi Mil Mi-8 helicopter.

If you're looking for the equivalent of m then it is -390

Step-by-step explanation:

-30 = m divided by 13 is the same as -30 times 13 = m

Finally m is equal to -390

Answer:

m = -390

Step-by-step explanation:

Given statement,

→ -30 = m divided by 13.

Forming the equation,

→ -30 = m/13

Now the value of m will be,

→ -30 = m/13

→ m/13 = -30

→ m = -30 × 13

→ [ m = -390 ]

Hence, value of m is -390.

The number of small boxes it is carrying is 60 and the number of large boxes it is carrying is 50.

The first step is to form a system of equations using the information in the question:

l + s = 110 equation 1

60l + 30l = 4800 equation 2

Where:

l = number of large boxes

s = number of small boxes

The elimination method would be used to solve these equations.

Multiply equation 1 by 60

60l + 60s = 6,600 equation 3

Subtract equation 2 from equation 3:

30s = 1800

Divide both sides of the equation by 30

s = 1800 / 30

s = 60

Substitute for s in equation 1

l + 60 = 110

l = 110 - 60

Equation of the form are considered quadratic equations: ax² + bx + c = 0, where a, b and c are constants. The most straightforward method of solving a quadratic equation by factoring is to express the equation in its factored form, and then solve for the values of x that make it true.

To solve, start by setting the equation equal to zero. This will simplify the equation and make it easier to factor.

The equation has to be factored after that. To do this, you will need to identify the factors of c that add up to b. For example, if c = 15 and b = 6, the factors are 3 and 5, since 3 + 5 = 6.

Once you have identified the factors, you can rewrite the equation in its factored form. For example, if c = 15 and b = 6, the equation can be rewritten as (x+3)(x+5) = 0.

Finally, you can solve the equation by setting each factor equal to zero. For instance, if the equation is (x+3)(x+5) = 0, then x+3 = 0 and x+5 = 0. Solving each equation separately, you get x = -3 and x = -5. Therefore, the solutions to the equation are x = -3 and x = -5.

In conclusion, to solve a quadratic equation by factoring you will need to set the equation equal to zero, identify the factors of the constant c that add up to the coefficient b, and then rewrite the equation in its factored form. Finally, you can solve for the values of x that make the equation true by setting each factor equal to zero.

Let the equation be y = Px + Qz. P and Q are constants, and x and z are 2 variables.

Firstly, make one variable 0, z = 0. This implies that you are dealing with only two variables, so you can make a graph(1) on X and Y axis. A simple line passes through the origin. Now take z = 1, and plot on the same plane, i.e., Plot y = Px + Q (this will be graph 2). Similarly, for all z. You will get a set of parallel lines separated by B.

Your monthly payment for this house will be $1689.5 if your mortgage payment is $1345, your annual insurance premium is $678, and your real estate taxes are $3456.

Describe the mortgage payments in brief?

Principal and interest payments make up your monthly mortgage payments. You must purchase private mortgage insurance if your down payment is less than 20%, which raises your monthly payment. Real estate or property taxes are also included in some payments. Early on in the mortgage, the borrower pays more interest, whereas the principle balance is favored in the latter stages. A greater down payment will directly increase your home's equity.

To find the total monthly payment for the home, we need to divide the annual costs by 12.

Total monthly payment = Mortgage payment + (Annual insurance premium / 12) + (Annual real estate taxes / 12)

= $1345 + ($678 / 12) + ($3456 / 12)
