Answer: A translation 5 units down followed by a 180-degree counterclockwise rotation about the origin .

Step-by-step explanation:

From the given figure, the coordinates of ΔABC are A(-3,4), B(-3,1), C(-2,1) and the coordinates of ΔA'B'C' are A'(3,1), B'(3,4), C'(2,4).

When, a translation of 5 units down is applied to  ΔABC, the coordinates of the image will be

Then applying 180° counterclockwise rotation about the origin, the coordinates of the image will be :-

which are the coordinates of ΔA'B'C'.

Hence, the set of transformations is performed on triangle ABC to form triangle A’B’C’ is " A translation 5 units down followed by a 180-degree counterclockwise rotation about the origin ".

salantis [7]

Answer:

The answer is

<h2>4260 N</h2>

Step-by-step explanation:

The force acting on an object when given the mass and acceleration can be found by using the formula

<h3>Force = mass × acceleration</h3>

From the question

mass = 142 kg

acceleration = 30 m/s²

So we have

Force = 142 × 30

We have the final answer as

<h3>4260 N</h3>

What is the value of x in the figure shown below
lesya [120]

Answer:

x = 30 degrees

Step-by-step explanation:

These triangles are perfectly symetrical. This is shown by the length of sides given in the problem. Since the triangle is symetrical, E is equal to B just as D is equal to C. Since B is 30 degrees, we can tell that E is also 30 degree.

Answer:

140ft.^2

Step-by-step explanation:

3.5 x 4 = 14 (the width)

2.5 x 4 = 10 (the length)

- to find the area of the rectangle, you multiply the width and length

14 x 10 = 140

if you need a more detailed explanation i am free to give one!!

Use the Remainder Theorem to determine which of the following is a factor of p(x) = x 3 - 2x 2 - 5x + 6.
Reika [66]
If x + 1 is a factor then f(-1) will = zero.

f(-1) =  8  so its not answer a).

f(3)  = 0   so the answer is x - 3

Its c.
