Answer:
2b^3
Step-by-step explanation:
A. 4y(2y + 5) = 4y(2y) + 4y(5) = 8y² + 20y
B. 7a(3a + 8b) = 7a(3a) + 7a(8b) = 21a² + 56ab
C. 13x³(3y + 2x²) = 13x³(3y) + 13x²(2x²) = 39x³y + 26x⁴ units²
D. 7m²(3m - 5) = 7m²(3m) - 7m²(5) = 21m³ - 35m² units²
Ok done. Thank to me :>
Answer: Answer for figure one is origin (0,0)
Answer for figure two is (2,4) /
Step-by-step explanation:
a) Here we can see that given graph is the equation of cubic function which is
f(-x) = -f(x) that is given function is odd then rotational symmetry point is origin always ,therefore point of rotational symmetry is origin (0,0)
b) The rotational symmetry of an ellipse is 180 degrees about the center of the ellipse .
And here the center of given ellipse is (2,4) ,therefore its rotational symmetry is about (2,4) That is if we rotate the given ellipse 180 degrees about (2,4) it will be at its original position.
The answer in this question is broadcast. Refer to curriculum topic: 5.1.3 On Ethernet networks, the broadcast MAC address is 48 binary ones displayed as hexadecimal FF-FF-FF-FF-FF-FF. So the hexadecimal address FF-FF-FF-FF-FF-FF represents broadcast the MAC address. The broadcast MAC address is a 48 binary.
To start off with, the probability to draw the short straw is 1/9 and each time someone picks the long straw the denominator (the 9) decreases by one which means that the odds of someone picking it get higher.
