Since \Delta x=\dfrac{b-a}n, and you have a corresponding term in the given Riemann sum of \dfrac5n, you know the integral is being taken over an interval of length 5, so you can omit the second choice.

Next, f(a+i\Delta x) corresponds to a=3 with \Delta x=\dfrac5n. The fact that a=3 alone tells you that the interval of integration starts at 3, and since we know the interval has length 5, that leaves the first choice as the correct answer.

Answer:

  see below

Step-by-step explanation:

A number line usually has numbers increasing from the right. If each unit on the number line represents $100, then a gain of $500 would be represented by the point at +5 units (right of 0). The loss would be represented by a point at -5 units, located left of 0.

The points are equidistant from 0 in opposite directions.

If f(x)= 3x + 1 and f^(-1)= x-1/3, then the ordered pair of f^(-1)(10)=
iragen [17]

The answer is B

The correct inverse of 3x+1 is actually (1/3)x - 1/3

plug in 10 to the inverse

10/3 - 1/3 = 9/3 or 3

this gives you the point (10,3)

The equation is put in slope intercept form which is y=mx+b

The slope is m and in this case it is -1/2.
To find the y intercept substitute in 0
for x then solve.
y =   - \frac{ 1}{2} (0) + 7
y = 7

How to solve this question?
bagirrra123 [75]

Answer:

-11.

Step-by-step explanation:

f(x) = √(3 - 2x),   x ≤ 3/2

let y = √(3 - 2x)

y^2 = 3 - 2x

2x = 3 - y^2

x = (3 - y^2)/2

So f-1(x) = (3 - x^2)/2  

f-1(x) = (3 - 5^2) / 2 = -11.
