Answer:
g(r - 9) = r² - 18r + 89
Step-by-step explanation:
To evaluate g(r - 9), substitute p = r - 9 into g(p) , that is
g(r - 9) = (r - 9)² + 8 ← expand factor using aFOIL
= r² - 18r + 81 + 8
= r² - 18r +89
Answer: 20 students mow on Saturday, 3 of those sleep until noon. Those who don’t mow the lawns, 21 of them sleep until noon.
Step-by-step explanation: 40% of 50 is 20. 25% of 20 is 3. 50-20=30. 70% of 30 is 21
1) A=p(1.015)^t
2)800=500(1.015)^t
800/500=1.015^t
Log(800/500)=t*log(1.015)
t=log(800/500)/log(1.015)
T=log(1.6)÷log(1.015)
T=31.6 years
Answer:
Step-by-step explanation:
The number to be added is the square of half of the linear term coefficient. Such coefficient in our case is "10" (the number accompanying the variable x). Then, half of it is 10/2 = 5, and that number squared gives 25.
Therefore, the number to add on bothsides of the equality is 25, which leads to the following:
This matches answer B) of your choices.
