Answer:
Surface Area varies by object/shape.
Ask your teacher/learning helper for those formulas of surface area
Step-by-step explanation:
Surface area is the sum of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
OK So this is how u do this:-
0.048*30=1.44
Hope I helped:D
Answer:
axc is 90 degrees. hope that helps
The last one
You’re completing the square here so you have to find (1/2b)^2. In this case it’s 1. So you have to add 1 to both sides. Then you have to solve for it
It becomes
(x-1)^2 = -7
Then you have to find the square root
(x-1) = √-7
x-1 = √7 √-1
x-1= ± i √7
x= 1 ±i √7
That’s your answer and d is the only one that matches with it
Answer:
- A'(-6, -8)
- B'(-7, -6)
- C'(-6, -4)
- D'(-5, -6)
Step-by-step explanation:
A 90° CCW rotation makes the transformation ...
(x, y) ⇒ (-y, x)
A translation 3 left and 2 down makes the transformation ...
(x, y) ⇒ (x -3, y-2)
The two transformations together are ...
(x, y) ⇒ (-y-3, x -2)
Then the given points are transformed to ...
A'(-6, -8)
B'(-7, -6)
C'(-6, -4)
D'(-5, -6)
