What is the F-14 known for?.
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. Budget cuts that came into effect in 1991, after the conclusion of both the Cold War and the Persian Gulf War, forced the early retirement of the Tomcat.

How do you find radical 3?.
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.

How do you solve a quadratic equation by factoring if it doesn't equal 0?.
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.

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)
= $1345 + $56.5 + $288

the perimeter of a major sector is 168cm.Given that the angle subtended by the minor arc at the centre of the circle is 72 degrees,calculate the area of the major sector
The area of the major sector is 2807. 1 cm²
How to calculate the area of the major sector?
The perimeter of a sector given by the formula:
P = θ/360 × 2πr
where r is the radius and θ is the angle subtended at the centre
Since the perimeter of a major sector is 168cm and the angle subtended by the minor arc is 72 degrees. We can say:
angle subtended by the major arc = 360 -72 = 288 degrees
P = θ/360 × 2πr
168 = 288/360 × 2πr
210 = 2πr
r = 210/2π
r = 33.42 cm
Thus, the radius of the major arc is 33.42 cm
The area of a sector given by the formula:
A = θ/360 × πr²
A = (288/360) × π × 33.42²
A = 2807. 1 cm²

A linear equation is an equation in which the highest power of the variable is 1. Linear equations can be written in the form of y = mx + b, where m is the slope of the equation, x is the variable, and b is the y-intercept, the point where the line crosses the y-axis. These equations are called linear because they describe a straight line when graphed.
It depends on the specific equations and the values of a, b, d and e in the system of equations. Multiplying both sides of an equation by a non-zero constant does not change the solution set of the equation.
However, if Jim wants to use the method of elimination, which is multiplying one equation by a constant and adding or subtracting it from the other equation, then it is important to ensure that the coefficients of one variable in the two equations are opposite in sign after the multiplication.

a delivery truck is transporting boxes of two sizes large and small. the large boxes weigh 60 pounds each and the small boxed weigh 30 pounds each. There are 110 boxes in all. If the truck is carrying a total of 4800 pounds in boxes how many of each type of box is it carrying?
The number of small boxes it is carrying is 60 and the number of large boxes it is carrying is 50.
How many of each type of boxes is it carrying?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
l = 50
