What's...factorise: 25x²-y²?

1 answer:

6 0

Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets

(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2

The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>

Find the distance between each pair of points.

scoundrel [369]

Answer:

(-1, -1) and (-4,5)

Distance between them ,

$\sqrt{ {( - 4 + 1)}^{2} + {(5 + 1)}^{2} }$

$= \sqrt{ {( - 3)}^{2} + {(6)}^{2} }$

$= \sqrt{9 + 36} = \sqrt{45} = 3 \sqrt{5}$

What equation I should use for this problem

Mama L [17]

I'm not completely sure, but this should be exponential growth.
If so, the equation for exponential growth is: y = a(1 + r)^t
If I substitute them with the information you gave me, then is would look like this:
y = 281.4(1 + 0.02)^t
**t = is the number of years after 2000 (based on your question)**
