Write the binomial expansion of (t-3)^5

postnew [5]

Answer:

Step-by-step explanation:

(t-3)^5 is the same as (t + (-3))^5

First: t starts at the highest power and goes down and (-3) starts at the lowest power and goes up

Second: from the Pascal triangles take the coefficients 1 5 10 10 5 1

$1*t^{5} (-3)^{0} + 5*t^{4} (-3)^{1} +10*t^{3} (-3)^{2} +10*t^{2} (-3)^{3} +5*t^{1} (-3)^{4} +1*t^{0} (-3)^{5}$

Anything to power 0 is equal to 1

Negative number to an odd power is negative, to a even power is positive

$t^{5} -15t^{4} +90t^{3} -270t^{2} +405t -243$

Well, you multiply the amount of tickets by the amount of money per ticket and add them together. 356 * 80 = 28,480 |||| 275 * 60 = 16,500|||| 369 * 45 = 16,605|||| 28,480 + 16,500 + 16,605 = 61,585. Therefor, C is your answer.

How do you find the legs of a right triangle when only given the hypotenuse?

tangare [24]

Answer:

We know that a^2+b^2=c^2. The 45° angle lets us know that y=x (45+45+90=180), so the problem is y^2+x^2=4sqrt of 2

$4 \sqrt{2} = \sqrt{32 } \\ \sqrt{32} ^{2} = 32$

So you get y^2+x^2=32, and from there, since we know x and y are equal, you can just divide 32 by 2 then take the square root of that, so the answer should be 4 for both x and y

Step-by-step explanation:

let me know if I'm wrong lol
