(f - g)(x) = (3x² + 1) - (1 - x)
= 3x² - x
OR
= x(3x - 1)
2.7 dollars. You round to the nearest tenth which means the first number after the decimal, which is six. Since there is a 5 after six, and 5 can be rounded positively, so the 6 becomes a seven
Answer:
3/8
Step-by-step explanation:
Find the height of the trapezoids
20 - 10 = 10
10/2 = 5
Find the area of the trapezoids
5*(20+10)/2 = 75
The formula for the area of the trapezoid is the height * the bases added together divided by 2
75*2(this is because there are 2 trapezoids) = 150
Put this to proportion of the total area of the dart board
150/
= 150/400 = 3/8
3/8 is the probability that you score 3 points
Answer:
y = 650·0.922^t
Step-by-step explanation:
At the end of each year, 92.2% of the amount at the beginning of the year remains. That is, the beginning amount is multiplied by 0.922. The exponent t in 0.922^t tells how many times (years) that multiplication has taken place. At the end of t years, the amount remaining in milligrams (y) is ...
y = 650·0.922^t
