So, the simplest form of 88/90 is 44/45
Answer:
11
Step-by-step explanation:
The average rate of change of function f on interval [a, b] is ...
m = (f(b) -f(a))/(b -a)
Here, that is ...
m = (f(6) -f(2))/(6 -2)
So, we need to evaluate the function at x=6 and x=2. Writing it in "Horner form" makes this easier.
f(x) = (x +3)x -2
f(6) = (6 +3)6 -2 = 54 -2 = 52
f(2) = (2 +3)2 -2 = 10 -2 = 8
Then the slope is ...
m = (52 -8)/4 = 13 -2 = 11
The average rate of change of f(x) from 2 to 6 is 11.
Answer:
b = 25m
Step-by-step explanation:
Hi there!
We're given angle B and the length of <em>a</em> in this right triangle. We must solve for the length of <em>b</em>. <em>a</em> and <em>b</em> are the two legs of the right triangle.
In this case, we can use the tangent ratio:
Plug in the given information:
Therefore, b = 25m.
We can also use this using special triangle rules. radians is equal to 45 degrees, making this a 45-90-45 triangle. This would make <em>a</em> and <em>b</em> equal in length.
I hope this helps!
