The graph shows how last a voltage signal rises in a elecommunications etreuit. The basis is the
vorage in volts and taxis is the time in seconds.
The function shown is v(t) = 10(1 - 4^-t)
Show why v(0) = 0.
How long does it take for the voltage to rise to 5
volts? Explain your answer using the function
and the laws of exponents.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
