A local electricity company charges $1.00 per kWh for the first 2000 kWh and $3.50 for every kWh afterwards. A fuel adjustment charge of $0.50 per kWh is added to all electricity bills. If Mrs. Browns previous
monthly meter reading was 17 800 kWh and the current monthly meter
reading is 20 300 kWh, calculate the electricity bill for Mrs Brown for
the current month​

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

Determine the maximum r-value of the polar equation r =3+3 cos 0

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
