Calculus

If your doing exponents (x squared) the answer is x. If your multiplying( X times 2) the answer is 2

81 x 4 equals 324. This can be calculated by multiplying 81 by 4, which is the same as adding 81 four times. In simpler terms, you can think of it as 81 multiplied by 4, resulting in the product of 324.

To solve the system of equations x^2 + xy + y^2 = 7 and 2x + y = 1, we can first solve the second equation for y to get y = 1 - 2x. Substituting this into the first equation yields x^2 + x(1-2x) + (1-2x)^2 = 7. Simplifying this equation gives a quadratic equation in terms of x, which can be solved to find two possible values for x. Substituting these values back into the equation y = 1 - 2x will give the corresponding values for y.

Oh, dude, like, 0.7 times 4 is 2.8. It's like, you just move the decimal point over one place to the right and boom, there's your answer. Easy peasy lemon squeezy.

Well, honey, writing half of x is as easy as slicing a pie. Just divide x by 2 and there you have it, half of x. It's like cutting a sandwich in half, simple as that. So, go ahead and show x who's boss by splitting it right down the middle.

Well, honey, it looks like you've got yourself a simple linear expression there. Just pull out the common factor of 2 from both terms, and you're left with 2(x + 7). That's all there is to it, darling!

310 can be divided by 1, 2, 5, 10, 31, 62, 155, and 310. These are factors of 310, meaning they can divide 310 evenly without leaving a remainder.

Oh, dude, half of 163 is like 81.5. It's like you take 163, cut it in half, and you're left with 81.5. Simple math, man, no need to stress about it.

It is P cubed or P3.

Oh, dude, "s.f." in math stands for significant figures. It's basically the number of digits that carry meaning in a measurement. So, like, if you're measuring something and you're like, "Oh, this is 5.23 meters," the "5," "2," and "3" are the significant figures. It's just a fancy way of saying, "These are the important numbers, pay attention to them."

Oh, dude, the value of x in that equation is 5. Like, you just add 3 to both sides, then divide by 7. It's like basic math, man.

The period of the tangent function, tan(x), is π because the tangent function has a repeating pattern every π units. This is due to the nature of the tangent function, which has vertical asymptotes at intervals of π. As x increases by π, the tangent function repeats its values, resulting in a period of π for the function.

2 x 22 equals 44. Multiplying 2 by 22 gives you the product of 44. In this case, 22 is the number that, when multiplied by 2, equals 44.

Well, honey, there are plenty of equations that can equal 41. For example, 20 + 21 = 41, or even 82 - 41 = 41. It's not rocket science, just simple math. So, pick your poison and make 41 your lucky number for the day.

The ratio of the surface areas of two similar objects is equal to the square of the ratio of their corresponding linear dimensions. Since the diameter of the moon is one fourth of the diameter of the Earth, the ratio of their diameters is 1:4. Therefore, the ratio of their surface areas is (1/4)^2 = 1/16. This means that the surface area of the moon is 1/16th of the surface area of the Earth.

Well, darling, 2x plus 5 is just an algebraic expression that represents the sum of 2 times a variable x and 5. So, if you want to find the value of that expression, you need to know the value of x. Math can be a real hoot sometimes, can't it?

Ans: ?

But all hope is not lost

You can cheat and do other things you must b3 asking why i beacause the math is too fricking hard 😬😧😦😭

Bye...

And hope this help😇🙋

Well, honey, that's a 95% increase. So, basically, you went from 20 to 39, which is a jump of 19. Divide that by the original number (20) and multiply by 100 to get your percentage. Voila, math magic!

Oh, dude, graphing y = -x^2 is like the easiest thing ever. You just make a sad parabola that opens downwards because of that negative sign in front of x^2. It's like flipping a smiley face upside down. So, grab your graph paper, plot some points, and voilà, you've got yourself a fancy-looking parabola!

In mathematics, the notation "y3" typically represents the cube of the variable "y," which is equivalent to y * y * y. This is a shorthand way of denoting the result of multiplying y by itself three times. The cube of a number is the number raised to the power of 3.

Halogens become less reactive down the column of the periodic table due to the increase in atomic size and the decrease in effective nuclear charge. As you move down the group, the atomic radius increases, leading to a decrease in the attraction between the outer electrons and the nucleus. This decrease in effective nuclear charge results in a weaker hold on the outer electrons, making it more difficult for halogens to gain an electron and exhibit their characteristic reactivity.

Oh, what a happy little math problem we have here. To factorise x squared plus 7x, we can first look for a common factor, which in this case is x. So, we can factor out an x to get x(x + 7). And just like that, we've created a lovely little factorised expression.

The answer to the expression 3x + 9 depends on the value of x. If x is a specific number, you would first multiply 3 by that number, then add 9 to the result. For example, if x = 2, the answer would be 3(2) + 9 = 6 + 9 = 15. However, if x is a variable, the expression 3x + 9 remains as is and cannot be simplified further without knowing the specific value of x.
