Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).

To solve the equation for 11 weeks, we replace x with 11.

2×11+12= 24
y=24

A swimmer does 3,560 J of work in 55 s. What is the swimmer's power output? Round your answer to two significant
Vesna [10]

Answer:

64.73 Watts

Step-by-step explanation:

We are given;

  • Work done by the swimmer = 3,560 J
  • Time, t = 55 seconds

We are required to calculate the power of the swimmer;

  • We need to know that power is the rate of doing work
  • That is, Power = Work done ÷ time

Therefore;

Power of the swimmer = 3,560 Joules ÷ 55 seconds

                                      = 64.727 Watts

                                      = 64.73 Watts

Thus, the power output of the swimmer is 64.73 watts

Find an explicit rule for the nth term of a geometric sequence where the second and fifth terms are -6 and 162, respectively. Pl
kicyunya [14]
Hello,

u_{0} =a\\
 u_{1} =a*r\\
 u_{2} =a*r^{2}=-6\\
 u_{3} =a*r^{3}\\
 u_{4} =a*r^{4}\\
 u_{5} =a*r^{5}=162\\
....\\
\boxed{ u_{n} =a*r^{n}} \\

\dfrac{ 162}{-6} = \dfrac{ u_{5} }{ u_{3}} = \dfrac{ a*r^{5}}{ a*r^{2}} =r^3= -27\\
==\ \textgreater \  r=-3\\

 u_{2} =a*r^{2}=-6=a*(-3)^2 \ ==\ \textgreater \  a=-\frac{6}{9} =-\frac{2}{3}\\


\boxed{ u_{n} =-\frac{2}{3}*(-3)^{n}=(-1)^{n+1}*2*3^{n-1}} \\

If you have 50 red bead 50 blue beads 50 green beads what I'd the probability that will be blue
makkiz [27]
Add all the beads together and put it over the number of blue beads.
so since there are 150 beads, the denominator is 150. and the amount of blue beads is 50 so that's the numerator.
50/150 now simplify, divide the numerator and denominator by 50 that equals
1/3
so the probability of getting a blue bead is 1/3
