I believe that f(2) is 34.5
f(2) = 2(34) + 1
f(2) = 68 + 1
f(2) = 69
f = 69/2
f = 34.5
I AM NOT SURE
Answer:
Area of 23958
Step-by-step explanation:
The Riemann sum is just the divide of a area into smaller areas and computing the sum of those areas. It is basically the integral of a function over an interval.
over the interval [0,33].

Answer:
91
Step-by-step explanation:
for a 2-digit number the tens digit (x) is 8 more than the ones digit (y) and no number is zero
=> x = y+8
x < 10
y > 0
y = 1 and x = 1 + 8 =9
the 2-digit is 91
Answer:85
Step-by-step explanation:
An oil change at City Auto is regularly $30. Mr. Allen has a coupon for 15% off. He wants to know the sale price of the service.
What is the relationship between the sale price and the regular price of an oil change? Complete the statement.
The sale price is (1,2 or 3)% of the regular price.
1. 15%
2. 30%
3. <u>85%</u>
A We can observe independently vertical component of arrows speed. Since there isn't vertical speed at start we can observe this case as free fall where formula for traveled distance is:
h = 1/2*g*t^2
we can express t
t = √2h/g
t = 1,427s
after 1.427 seconds in air arrow will hit ground.
B. The range we get simply by calculating how much distance will arrow travel in 1.427 seconds at speed of 64.5m/s. speed is not changing because we are ignoring air resistance.
s = t*v = 93.468m
