Answer:

(-2, 3)

Step-by-step explanation:

Think of this in the future:

Counter-clockwise rotations:

90-degree --> (x,y) = (-y,x) ex. (3,2) --> (-2,3)

180-degree --> (x,y) = (-x,-y) ex. (3,2) --> (-3, -2)

270 degree --> (x,y) = (y,-x) ex. (3,2) --> (2, -3)

Clockwise rotations:

90-degree --> (x,y) = (y, -x) ex. (3,2) --> (2, -3)

180-degree --> (x,y) = (-x,-y) ex. (3,2) --> (-3,-2)

270-degree --> (x,y) = (-y, x) ex. (3,2) --> (-2,3)

If triangle ABC is dilated using a scale factor of 2, what will be the coordinates of A after the transformation

harkovskaia [24]

Answer:

$A' = (-4,4)$

Step-by-step explanation:

Given

$A = (-2,2)$ $B = (1,3)$ $C = (1,0)$

$k =2$ --- scale factor

Required

Determine A'

This is calculated as:

$A' = A * k$

$A' = (-2,2) * 2$

$A' = (-2 * 2,2 * 2)$

$A' = (-4,4)$

Find the simple interest earned to the nearest cent for each principal, interest rate, and time.

mafiozo [28]

Answer:

for the first one its I=38.40 for the 2nd one its $315

Step-by-step explanation:

Simple interest , I, is calculated by multiplying the principal, P, by the rate,r, by the time, t, in years:

I = P * r * t

Here, P = $640

r = 0.03 (decimal value for 3%)

t = 2 years

The interest will be:

I = P * r * t

I = 640 * 0.03 * 2

I = $38.40

2nd one:

We know, Interest value = P * R * T /100

Here, P = 1500

R = 4.25

T = 4

Substitute their values,

I = 1500 * 5.25 * 4 / 100

I = 31500 / 100

I = 315

In short, Your Final Answer would be $315

3rd answer:

assuming you subtract 2% of 580 a month for six months. your remaining money would be $510.40

because you subtract $69.6 from 580

4th answer:

$1231

Step-by-step explanation:

Given,

Principal amount = $1200

Rate of interest = 3.9%

Time = 8 months or (8/12) 0.666667 years

Formula of simple interest =

A = 1200(1+(0.039 × 0.666667))

A = 1200 (1+0.026)

A = 1200 (1.026)

A = $1231
