Assuming that's a 40 minutes a lesson the minutes the tennis teacher teaches in a week is 800 minutes
Increased by 15
past score was x
increased by 15 means he raised to 15+x
it was raised to 83%
therefor
x+15=83
first option is right (and first test was 68%)
You substitute the y from the second eqaution to the y in the first equation
Answer:
Step-by-step explanation:
T(1)=1=0*x^3 0*x^2 0*x 1*1 T(x)=x-1=0*x^3 0*x^2 1*x (-1)*1 T(x^2)=2x^2-6x 6=0*x^3 2*x^2 (-6)*x 6 T(x^3)=6x^3-48*x^2 141*x-141 T(x^4)=24*x^3-204*x^2 628*x-604*1 collect the coefficient matrix and take its transpose
0 0 0 6 24
0 0 2 -48 -204
0 1 -6 141 628
1 -1 6 -141 -604
After two years with the interest compounded annually the amount would be $1,060.90.
After two years with the interest compounded monthly the amount would be $1,061.76.
After two years with the interest compounded quarterly the amount would be $1,061.60.
After two years with the interest compounded semiannually the amount would be $1,061.36.
