f(x) = 3x + 5 f(x) = 6x^2 + 1 g(x) = 22 - 8x^3 H(x) = 14x^2 + 52x^3 - 8√x It can really be any algebraic expression. A function is defined as "a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output."...

The acceleration is centripetal (circular): a = velocity^2 /radius (formula) = 240^2 /24 = 2400 rad/s^2 Linear velocity is calculated using the formula v = u + at. That is: final velocity = initial velocity + acceleration x time linear velocity = 0 (since...

If this is a multiple choice question, can't you just test each? e.g. for (A): -160 x -2 = 320 Therefore, the answer is "multiply the previous term by -2" To check that the rest are incorrect: for (B): -160 /2 ≠ 320 for (C): -160 - 60 ≠ 320 for (D): -160...

I feel like this question might be missing some vital information. Is this a 3D trigonometry question? If so, I'm not sure it can be solved without being given an additional length or some bearings/elevation angles.

To find the capacity (amount of water), you must first find the volume. This prism is a cylinder (since it has a circular base). Find radius: Circumference = 2πr r = C/2π = 16/2π = 8/π feet (= 2.55) Find volume: Volume = Area x height = πr^2 x h = π x (8/...

the length of the arc of a sector is given by the radius times the angle bisected at the centre. l = 14 x 45 = 630cm Then you just add twice the radius (the two sides of the sector) The perimeter = 360 + 14 + 14 = 388 cm I don't believe you need to use pi...

You need to get a common base. In this question, your bases are 36, 6, 6. Use a base of 6 (and hence change 36 to 6). 36 = 6^2 36^5x = 6^2(5x) = 6^10x Your equation now is: 6^10x = 6^(x+x-2) INDEX LAWS Since we have the same base, the powers must be equal...

Walking along two of its adjacent sides: 24 + 18 = 42cm Draw the diagonal (to form two triangles). Find the hypotenuse of one of the triangles to find the diagonal. Use pythagoras theorem: c = sqrt[a^2 + b^2] = sqrt[24^2 + 18^2] = 30cm Therefore, it is 12...

I think 18 works. (18/2)^2 = 81
