Answer:

$y = -(0.03(x-90)^2)+240$

Step-by-step explanation:

I hope you already understand how parabolas work, so here are the steps/equations you need:

$y=\ -\left(a\left(x-c\right)^{2}\right)+\ b$

$a=\frac{H}{\left(\frac{T}{2}\right)^{2}}$

$c=\frac{T}{2}$

$b\ =\ H$

$H = 240$

$T = 180$

$a= 0.0296296296296$

$c= 90$

$b=240$

Now that you have "a", "c", and "b", plug them into the very first formula. This is the final result you get:

$y = -(0.03(x-90)^2)+240$

. If the expressions x + 5, 2x, and 4x −17 represent the first three terms of an arithmetic sequence, then determine the numeric

Vika [28.1K]

Answer: The value of 20th term is 150.

Step-by-step explanation:

Since we have given that

$x+5,2x,4x-17$

Since they are in AP.

So, we know that

$2b=a+c\\\\2(2x)=x+5+4x-17\\\\4x=5x-12\\\\4x-5x=-12\\\\-x=-12\\\\x=12$

So, the first term would be :

$x+5=12+5=17=a$

common difference would be :

$2x-(x+5)\\\\=2x-x-5\\\\=x-5\\\\=12-5\\\\=7$

So, the value of 20th term would be :

$a_{20}=a+19d=17+19\times 7=17+133=150$

Hence, the value of 20th term is 150.
