1 answer:

7 0

I'm not sure what your statement is.
Is it x+y = 10?

Because if it is, the negation of this statement would simply be x+y<span>≠10, which stands for not equal. </span>

Given the below sequence:-1, -3, -5, -7, . . .

vekshin1

Answer:

A. The next 3 terms are —9, —11, —13

B. The sequence is Arithmetic

C. The sequence has a common difference of —2

Common difference = T2 — T1 or = T3 — T2

=T2 — T1 = —3 —(—1) = —2 or

= T3 — T2 = —5 —(—3) = —2

D. Tn = a + d(n—1)

a = first term = —1

d = Common difference = —2

n = 27

T27 = —1 + —2(27—1)

T27 = —1 + —2(26)

T27 = —1 —52

T27 = —53

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric

Murrr4er [49]

Answer:

$A = 781250\,m^{2}$ , $x = 625\,m$ , $y = 1250\,m$

Step-by-step explanation:

The perimeter covered by the electric fence in meters is:

$2\cdot x + y = 2500$

The area of the rectangle is:

$A = x\cdot y$

$A = x \cdot (2500-2\cdot x)$

Let differentiate the previous equation and equates to zero:

$2500-4\cdot x = 0$

The critical point is:

$x = 625\,m$

By the Second Derivative Text, it is proved that critical point lead to a maximum:

$\frac{d^{2}A}{dx^{2}} = -4$

The other side of the rectangle is:

$y = 1250\,m$

The largest area than can be enclosed is:

$A = (625\,m)\cdot (1250\,m)$

$A = 781250\,m^{2}$

The dimensions of the triangle are:

$x = 625\,m$

$y = 1250\,m$

How to factor 18a2+6a5-8a3

Zielflug [23.3K]

Answer:

$2a^2(3a^3-4a+9)$

Step-by-step explanation:

You could change the equation to this: $6a^3a^2-8a^1a^2+18a^2$

*This is the exact same as $18a^2+6a^5-8a^3$

You can continue to break this down until you get:

$2*3a^3a^2-2*4a^1a^2+2*9a^2$

*This too = $18a^2+6a^5-8a^3$

With this new equation, you can cancel out the common term: $2a^2$

You come up with my answer.

<em>Hope this helps!!</em>
