A triangle has vertices at B(−3, 0), C(2, −1), D(−1, 2). Which transformation would produce an image with vertices B″(−2, 1), C″

(3, 2), D″(0, −1)?
(x, y) → (x, −y), (x, y) → (x + 1, y + 1)
(x, y) → (−x, y), (x, y) → (x + 1, y + 1)
(x, y) → (x, −y), (x, y) → (x + 2, y + 2)
(x, y) → (−x, y), (x, y) → (x + 2, y + 2)

Answer:

A. (x, y) → (x,-y), (x, y) → (x + 1, y + 1)

Step-by-step explanation:

Plot points B, C and D on the coordinate plane (blue points in attached diagram).

1 transformation is reflection across the x-axis with the rule

(x,y)→(x,-y)

and it maps these points to

  • B(-3,0)→B'(-3,0)
  • C(2,-1)→C'(2,1)
  • D(-1,2)→D'(-1,-2)

These image points are marked in green in attached diagram.

2 transformation is translation 1 unit to the right and 1 unit up with the rule

(x,y)→(x+1,y+1)

and it maps previous image points to

  • B'(-3,0)→B''(-2,1)
  • C'(2,1)→C''(3,2)
  • D'(-1,-2)→D''(0,-1)

What fraction of 30 is 12
zloy xaker [14]

Call the mystery fraction ' F ' (for 'fraction').

12 is the mystery fraction of 30 .

                                             12  =  F x 30

Divide each side by  30 :      F  =  12/30  =  2/5 .

Malcolm and Ravi raced each other.
Semenov [28]

Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h

Step-by-step explanation:

Lets assume Malcolm maximum speed to be M km/h and Ravi  maximum speed to be R km/h

Average of their maximum speed is; (M+R)/2 =260 km/h

This can be simplified to M+R= 260*2

M+R = 520.......................................(I)

When Malcolm's speed is doubled,

2M=R+80 km/h ----------------------(ii)

The two equations are;

M+R = 520 ------ M=520-R ----(i)

2M=R+80 ---------------------------(ii)

Replacing M with (i) above

2M=R+80

2(520-R) =R+80

1040 -2R =R+80

1040-80 = R+2R

960 = 3R

960/3 =R

320 =R

M+R =520

M=520-320 =200

Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h

Each function below describes how something changes. Use the description to determine which function(s) describe exponential gro
cestrela7 [59]

Answer: E. The population decreased by 11% each year.

Step-by-step explanation: In A, the pollution increases at a constant rate, but in a linear way, in other words in each day, the pollution increases 10 grams; The same goes for C: ice "grows" a few milimeters each day; In D, as volume is calculated by the multiplication of π and its radius, the increase in the volume is still linear. In B, the proportionality is related to the power of the turbine not the growth or decay of it. In E, a population grows or decreases in a form of A=A₀(1±r)^t. In this case: A = A₀ (1-0.11)^t.

In conclusion, the function that better describes an exponential growth or decay is the decrease of a population.

Let C be the closed, piecewise smooth curve formed by traveling in straight lines between the points (-2,1), (-2,-3), (1,-1) , (
Greeley [361]

The given points are the vertices of the quadrilateral

Q=\left\{(x,y)\mid-2\le x\le1,\dfrac{2x-5}3\le y\le\dfrac{4x+11}3\right\}

By Green's theorem, the line integral is

\displaystyle\int_C2xy\,\mathrm dx+xy^2\,\mathrm dy=\iint_Q\frac{\partial(xy^2)}{\partial x}-\frac{\partial(2xy)}{\partial y}\,\mathrm dA

=\displaystyle\int_{-2}^1\int_{(2x-5)/3}^{(4x+11)/3}y^2-2x\,\mathrm dy\,\mathrm dx=\boxed{61}
