A cube has 6 faces. The surface area of a cube is 6 times the area of one face.
SA = 6s^2
SA = 6 * 6cm^2
SA = 6 * 36cm^2
SA = 216cm^2
Answer:
3.4
Step-by-step explanation:
3.4 is able to be converted into a fraction so it is rational.
For problem 2, you are correct in stating that a curve forms. Specifically, if we were to trace along the outer edge of the shape, then we'd form a <u>parabola</u> that has been tilted 45 degrees compared to the more familiar form that students are taught (where the axis of symmetry is vertical).
For more information, search out "Tangent method for parabolas". As the name implies, the tangent method draws out the tangents of the parabola which helps form the parabola itself.
Everything else on your paper is correct. You have problem 1 correct, and the table is filled out perfectly. Nice work.
Answer:
The answer is 8.
Step-by-step explanation:
6-8+7-2-8+13
= (6 +7 + 13) - (8+2+8)
= 26 - 18
= 8
Answer:
The last one
Step-by-step explanation:
Domain is on the x - axis, so it starts and stops on 1 and 6 and all the other symbols mean that x could be 1, 6, or anything in between. Range is on the y - axis, so the highest point is seven and the lowest is one. Y could be 1, 7, or anything in between.
