What is net change in math?

1 answer:

<span>Net change basically means that when you're done with EVERYTHING, how far did you move from the beginning. </span>

So in this case, let's say that you started up on the 1st floor, you went up to the 5th, down to the 2nd level of the garage, up to the 1st again then up to the 2nd floor. You started on the 1st floor and ended up on the 2nd floor, so the NET CHANGE is 1 floor up. sound clear?

Triangle GHJ with vertices G(-2, 4), H(3, 6), and J(3, -2) is dilated by a factor of 1/3 centered at the origin. What are the co

Grace [21]

Answer:

The coordinates of G' are $G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$ .

Step-by-step explanation:

From Linear Algebra, we define the dilation of point G by the following expression:

$G'(x,y) = O(x,y) + k\cdot [G(x,y)-O(x,y)]$ (1)

Where:

$O(x,y)$ - Center of dilation, dimensionless.

$k$ - Scale factor, dimensionless.

$G(x,y)$ - Coordinates of point G, dimensionless.

$G'(x,y)$ - Coordinates of point G', dimensionless.

If we know that $O(x,y) = (0,0)$ , $k = \frac{1}{3}$ , $G(x,y) = (-2,4)$ , then the point G' is:

$G'(x,y) = (0,0) + \frac{1}{3}\cdot [(-2,4)-(0,0)]$

$G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$

The coordinates of G' are $G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$ .

How much much interest is on earned on an account if... Principal= $1,250 Rate= 5.7% Time= 4 year

Free_Kalibri [48]

Alright, lets gets started.

I suppose , we are asked to find simple interest for above question.

Principal P = $1,250

Rate r = 5.7 %

Time t = 4 years

The formula for simple interest = $\frac{P*r*t}{100}$

Hence simple interest $= \frac{1250*5.7*4}{100}$

Simple interest $= \frac{28500}{100}$

Simple interest = 285 $

Hence interest earned is $ 285. : Answer

Hope it will help :)

Y∝√x If y=60 when x=36 find,y when x=16

avanturin [10]

Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x." We are told that y = 60 when x = 36. Find the formula for this function. Then, determine what value y will take on when x = 16.

y = k√x becomes 60 = k√36, or 60 = 6k. Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40
