Your speed is 13 ft/sec. In order to know our velocity, we would need to know what direction we're moving. You haven't told us anything about our direction, only that our speed is 13 ft/sec.

In this equation, y-4/2=10, would i need to get the same denominator<br> y-4/2=10/2 = y-2=5?

Natasha_Volkova [10]

No actually you can just multiply both sides of the equation by 2 and get y-4=20. then add 4 to both sides to get y=24.

Evaluate the definite integral using the graph of f(x)<br> (Image included)

Tanya [424]

a) The first integral corresponds to the area under y = f(x) on the interval [0, 3], which is a right triangle with base 3 and height 5, hence the integral is

$\displaystyle \int_0^3 f(x) \, dx = \frac12 \times 3 \times 5 = \boxed{\frac{15}2}$

b) The integral is zero since the areas under the curve over [3, 4] and [4, 5] are equal but opposite in sign. In other words, on the interval [3, 5], f(x) is symmetric and odd about x = 4, so

$\displaystyle \int_3^5 f(x) \, dx = \int_3^4 f(x) \, dx + \int_4^5 f(x) \, dx = \int_3^4 f(x) \, dx - \int_3^4 f(x) \, dx = \boxed{0}$
