Answer:

A scaled copy is a copy of an figure where <u>every</u> length in the original figure is multiplied by the same number.

The original figure A is 2 units wide and 2 units high.  The scaled copies must follow the same ratio of width to height (2 : 2), as well as the vertices of the figure remaining the same.

Therefore, figures 2 and 4 are scaled copies only.

No, for figure B to be a scaled copy, the width would also have to be scaled down. As the width has remained the same in both figures, figure B is not a scaled copy.

A & D are scaled copies

<u>Question 4</u>

1.  5 · 3 = 15

2. 4 · 8 = 32

3. 6 · \dfrac32 = 9

4. 12 · \dfrac14 = 3

Answer:

Figure 2 and figure 4

Yes I agree with Tyler

A

C
D

Step-by-step explanation:

Figures 2 and 4 are not slanted which changes the original form, unlike the others.

I agree with Tyler because the size is not only smaller but it says that it was scaled by 2 more centimeters than the original figure.

I believe its the others because the other one is scaled upwards unlike the rest.

If an object is shot with an initial velocity of 160 ft/sec, what is the smallest initial angle will you need to obtain a horizo
MrRissso [65]
To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63

Answer:

{x}^{3} + {x}^{2} −24x+36

Step-by-step explanation:

(x + 6)(x - 2)(x - 3)

[x(x−2)+6(x−2)](x−3)

( {x}^{2} −2x+6x−12)(x−3)

( {x}^{2} +4x−12)(x−3)

{x}^{3} + {x}^{2} −24x+36

????????????????????????????
Nina [5.8K]
X= 70 degrees
Y= 70 degrees

Understand that every triangle has three angles and they add up to 180 degrees.

If I split this triangle in half the total degrees of each individual piece will be 90 degrees. A split in the isosceles triangle will also cause the 40 degrees to halved (thus, how I got 20 degrees in our 90 triangle).

Since we are dealing with an isosceles triangles two of the sides will be equal (hence, the dashes on the triangles sides). Therefore, x and y will also be equal.

Now if our 40 degreed angle is now 20 degrees, we have an unknown angle and the triangle in total now adds up to 90 degrees we can set up an equation.

20 + y = 90

Y = 70

Since X and Y are equal, X will also be 70.

If we return to to the isosceles triangle before it was split (use your photo for reference) and we add 40 +70 + 70 we will get 180 degrees. Which is the standard total of degrees for any triangle that is not a 90 degreed triangle.

I hope this helps. Feel free to ask questions.
