TriangleABC is transformed to form triangleA'B'C' .

ExtremeBDS [4]

A=(2,4); B=(3,9); C=(4,1)
A'=(4,-2); B'=(9,-3); C'=(1,-4)

All the points P=(x,y) change to P'=(y,-x), this corresponds to a rotation counterclockwise about the origin, then:

Answer: Triangle ABC is
First box: rotated counterclockwise
Second box: 90° about the origin
to form triangle A'B'C'

Will give crown thingy if right Can you find the area and circumference of a circle given the radius or diameter?

Artist 52 [7]

Answer:

Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.

Step-by-step explanation:

i) to find the area of a circle or circumference the radius , r, is required.

ii) if we are given the diameter, d. then we have to find the radius, r, by dividing the diameter by 2, that is $d = \frac{r}{2}$ .

iii) area of the circle is given by A = $\pi r^{2}$

iv) circumference of the circle is given by C = $2\pi r$

Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.

Calculating area of rectangle

PSYCHO15rus [73]

Answer:

$Area = 216.108cm^2$ --- You

$Area = 216.940cm^2$ --- Another student

Reason: Because there is a variation in the given dimensions

Step-by-step explanation:

Given

Your measurement

$Length = 20.70cm; Width =10.44cm$

Another students'

$Length = 20.74cm; Width =10.46cm$

Solving (a): The area

Area is calculated as:

$Area = Length * Width$

For you

$Area = 20.70cm * 10.44cm$

$Area = 216.108cm^2$

For the other student

$Area = 20.74cm * 10.46cm$

$Area = 216.940cm^2$

Solving (b): Reason for the variation in the areas

The given measurements are estimates of the dimensions of the rectangle.

Since there is a variation in the estimates, there will be some level of variation in the calculated area.

Error Analysis: Kayla said the remainder of x^3+ 2x^2 -4x + 6 divided by

andrezito [222]

9514 1404 393

Answer:

C) No, Kayla is not correct, because the remainder is -49 not 149

Step-by-step explanation:

The remainder from division by x+5 can be found by evaluating the polynomial at x=-5, the value of x that makes the divisor zero.

Evaluation is often easier when the function is written in Horner form.

((x +2)x -4)x +6

For x=-5, this is ...

((-5 +2)(-5) -4)(-5) +6 = (-3(-5) -4)(-5) +6 = 11(-5) +6 = -49

Kayla is not correct; the remainder is -49.
