3y^-4 × (2y^-4) = 6y^-8
= 6/1/y^8
= 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3
= x^3
2) y^-1 = 1/y
3^-2 = 1/3^2 = 1/9
5^-2 = 1/5^2 = 1/25
Answer:
Step-by-step explanation:
Distance between two points and is given by the formula,
Distance =
a). A(-6, -4), B(-3, -1)
Distance between A and B =
=
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D =
=
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance =
=
= 10√2
= 14.14
≈ 14.1 units
Okay. So the keynote speaker has 1/4 of an hour to speak, which means that 1 1/4 hours or 75 minutes are left for speakers. To find out the amount of time for each of the remaining 5 speakers, you have to divide 75 by 5. 75/5=15. The remaining 5 speakers will have 15 minutes to give their speech.
