Where are the points for Y=-x^2+160x-5000

1 answer:

4 0

None are given. You have to invent your own points that satisfy the given equation.

Examples: If x = 0, y = -5000 => (0,-5000)
If x = 2, y = -(2)^2 + 160(2) - 5000 = 4 + 320 - 5000 => (2, -4676)

and so on. Find as many such points as you want, using the same approach.

Answer:

$x=\frac{13}{2}, y=\frac{51}{4}$

Step-by-step explanation:

$We\ are\ given,\\3x-2y=-6\\5x-2y=7\\Considering\ this\ system\ of\ equations,\\Let\ 3x-2y=-6\ be\ E_1\\Let\ 5x-2y=7\ be\ E_2,\\Hence,\\Multiplying\ E2\ with\ -1, we\ get:\\3x-2y=-6\\-1(5x-2y)=7*-1\\Hence,\\3x-2y=-6\\-5x+2y=-7\\Now,\\Lets\ add\ E_1\ and\ E_2\ together\\Hence,\\(3x-2y)+(-5x+2y)=(-6)+(-7)\\Hence,\\3x-2y-5x+2y=-13\\Arranging\ And\ Adding\ Like\ terms,\ we\ have:\\3x-5x-2y+2y=-13\\Hence,\\-2x+0y=-13\\-2x=-13\\x=\frac{-13}{-2}=\frac{13}{2}$

$Now,\ we\ can\ substitute\ x=\frac{13}{2}\ in\ E_1\ or\ E_2,\\But,\\Here,\ we'll\ substitute\ it\ in\ E1,\\Hence,\\Substituting\ x=\frac{13}{2}\ in\ E1,\ we\ have:\\3*\frac{13}{2}-2y=-6\\\frac{39}{2}-2y=-6\\-2y=-6- \frac{39}{2}\\-2y=\frac{-12-39}{2}\\-2y=\frac{-51}{2}\\y=\frac{-51}{2*-2}=\frac{51}{4}\\Hence,\\x=\frac{13}{2}, y=\frac{51}{4}$

FIRST QUESTION!!!!

aleksley [76]

Option B: 1088 is the next term in the geometric sequence.

Explanation:

The sequence is $17,68,272$

We need to determine the next term.

To determine the next term, let us find the common ratio between the terms.

$r=\frac{68}{17} =4$

$r=\frac{272}{68} =4$

Thus, the common ratio is $r=4$

And the given sequence is a geometric sequence.

To determine the next term in a geometric sequence, we always multiply the common ratio to the current term.

Hence, the current term is 272 and the common ratio is 4.

Next term = Current term × Common ratio

$=272\times4$

$=1088$

Thus, the next term of the geometric sequence is 1088

Therefore, Option B is the correct answer.

What is the explicit formula for the geometric sequence: 224, 112, 56, 28, ... .

UkoKoshka [18]

Answer:

a_n=224(1/2)^n-1

Step-by-step explanation:

In this geometric sequence, we can see that the common ratio is 1/2 and the 1st term is 224. using this information, we can plug it into the geometric series formula and we get a_n=224(1/2)^n-1.
