Answer:
a: -13º
b: 83º
Step-by-step explanation:
- a: º
- b: º
- the equation would originally be written as 68 - -15 but 2 negatives make a positive so -- becomes +
hope this helps :)
For a regular 8 sided polygon each angle against each side, is 360/8=45.
So x=45/2=22.5
Then
9514 1404 393
Answer:
- a) 7
- b) -27
- c) 18
- d) 8
- e) 2
- f) 1
Step-by-step explanation:
The limit of any polynomial function at a point is the value of the polynomial at that point. A polynomial is defined and continuous for all values of the independent variable.
The limit of a rational function at a "hole" is the value of the simplified function at that point.
1a) lim = 4+3+2-2 = 7
1b) lim = (3)(-3)(3) = -27
1c) lim = 3^2+9 = 18
1d) lim = (x+4) = 4+4 = 8
1e) lim = 3x+1 = 3(1/3) +1 = 2
1f) lim = x^2/x^2 = 1

The expressions of (e) and (f) can be simplified by factoring the difference of squares: a^2 -b^2 = (a -b)(a +b). In each case, one of the factors cancels the one in the denominator, so the remaining function can be evaluated at the limit point.
As x approaches infinity, the only terms of a rational expression that matter are those of the highest degree in numerator and denominator. (There's a little more to it if the numerator has a higher degree than the denominator.)
Answer:
y=3x-1
Step-by-step explanation:
First, we must find the slope of the equation. To do that we take two ordered pairs from the graph.
(2,5) (10,29)
The equation for slope is m=y2-y1/x2-x1
m=29-5/10-2
m=24/8
m=3
Now, we will find the variable B.
5=3(2)+b
5=6+b
-1=b
That's how we get the equation!
y=3x-1
Answer:
Step-by-step explanation:
Switch sides:
Subtract r from both sides:
Divide both sides by p:
