Answer:
-2 hope this helps! :)
Step-by-step explanation:
-10 over 5 is -2
so a = -2
Answer:
<h2>
4x+4</h2>
Basic fact:
<em>all sides of a square are equal</em>
Step-by-step explanation:
1 side is x+1 so all sides are x+1
there are 4 sides so times everything by 4
4(x+1) which is 4x+4
Step-by-step explanation:
The vertex form of a parabola can be written as
where (h, k) are the coordinates of the parabola's vertex. The vertices of the functions are as follows:
a) (3, 5)
b) (-7, 3)
c) (4, 0)
d) (0, -1)
e) (-1, -5)
f) (-1, -5)
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
Answer:
15.9
Step-by-step explanation:
A, O
Tan=O/A
Tan47=17/x
x=17/tan 47
