a psychologist contends that the number of facts of a certain type that are remembered after t hours is given by the following f
laiz [17]

Answer:

At t=1, Rate of Change=-36.86

At t=10 hours, Rate of Change =-0.0088

Step-by-step explanation:

The function which describes the number of facts of a certain type which are remembered after t hours is given as:

f(t)=\frac{85t}{99t-85}

To determine the Rate of Change at the given time, we first look for the derivative of f(t).

Applying quotient rule:

f^{'}(t)=\frac{-7225}{{\left( 85 - 99\,t\right) }^{2}}

At t=1

f^{'}(1)=\frac{-7225}{(85-99)^{2}}

=-36.86

At t=10 hours

f^{'}(10)=\frac{-7225}{(85-99(10))^{2}}

=-0.0088

Express it in slope-intercept form.
GREYUIT [131]

Answer:

  y = (2/3)x -1

Step-by-step explanation:

The line crosses the y-axis at -1, so that is the y-intercept.

From that point. the next grid intersection is 3 units to the right and 2 units up, so the slope is ...

  m = rise/run = 2/3

The slope-intercept form of the equation of a line is ...

  y = mx +b . . . . . where m is the slope (2/3) and b is the y-intercept (-1)

Your line has equation ...

  y = (2/3)x -1

Triangle RST is shown below. What is the length of ST?
Tju [1.3M]

Answer:

A: 12

Step-by-step explanation:

Using the pythagoreom theorem, a^2+b^2=c^2. We can plug in the lengths of 5 and 13 which is 5^2+b^2=13^2. Now we can square the numbers to get 25+b^2=169. Subtract 25 from 169 to get 144. Now find the square root of 144 which is 12.
