The negative sign on an exponent means the reciprocal. Think of it this way,
just as a positive exponent mean repeated multiplication by the base, a negative exponent means repeated division by the base.
Example
So 2^ (-4)= 1 / (2^4)=1/(2*2*2*2)=1/16
So that answer would be 1/16

A triangle has two angle measures of 20 degrees and 30 degrees. Find the third angle. This triangle is a(n) ________ triangle
A) Acute
B) obtuse
C) Right
D) It does not make a triangle.
Oml just help. ;-; (There is no picture just the question and choices).
Answer:
B) obtuse
Step-by-step explanation:
Key skills needed: Triangle measure, Triangle Recognition
1) First we need to find the measure of the 3rd angle, and then we can determine what type of triangle it is.
2) The sum of all the interior angles in a triangle add up to 180 degrees. Let's say x is the measure of the 3rd angle.
This means --> [tex]20 + 30 + x = 180[/tex]
20 + 30 is 50, so --> [tex]50+ x = 180[/tex]
Subtract 50 from both sides and you will get x = 130
This means the 3rd angle measures 130 degrees.
3) Now, we have a triangle with a 20 degree angle, a 30 degree angle, and then a 130 degree angle.
An angle with measure with 130 degrees is an obtuse angle
(Keep in mind that an acute angle has a measure less than 90 degrees, a right angle measures 90 degrees, and an obtuse angle has a measure of more than 90 degrees - 130 is more than 90 so it is obtuse)
4) A triangle with 1 obtuse angle is an obtuse triangle, so Choose B) obtuse!!

Answer:
the graph to the left and down
Step-by-step explanation:
As we can see, the slope shows as 3, and it is always going to be three, so we can cross out the two graphs on the top. But the graph also shows the y-intercept to be 7, which means that the point that lands on the vertical line will be (0,7). This narrows it down to the graph on the left to the bottom.
Here is a polygon. The side lengths are: AB= 18 units, BC= 12 units, CD= 6 units, and DA= 24 units.
1. If polygon ABCD is dilated using center A and scale factor LaTeX: \frac{1}{2}1 2, what will be the side lengths of dilated polygon EFGH?
EF= ____, FG= ____, GH= ____, HE= ____
2. If polygon ABCD is dilated using center D and scale factor LaTeX: \frac{1}{3}1 3, what will be the side lengths of dilated polygon IJKL?
IJ= ____, JK= ____, KL= ____, LI= ____
3. How do you know that polygons EFGH and IJKL are similar?
Answer:Given : Polygon side lengths are: AB= 18 units, BC= 12 units, CD= 6 units, and DA= 24 units.
polygon ABCD is dilated using center A and scale factor 1/2
polygon ABCD is dilated using center D and scale factor 1/3
To Find :
side lengths of dilated polygon EFGH
EF= ____, FG= ____, GH= ____, HE=
side lengths of dilated polygon IJKL?
IJ= ____, JK= ____, KL= ____, LI= ____
Solution:
AB= 18 units, BC= 12 units, CD= 6 units, and DA= 24 units.
EF= AB/2 = 18/2 = 9
FG = BC/2 = 12/2 = 6
GH = CD/2 = 6/2 = 3
HI = DA/2 = 24/2 = 12
IJ= AB/3 = 18/3 = 6
JK = BC/3 = 12/3 = 4
KL= CD/3 = 6/3 = 2
LI = DA/3 = 24/3 = 8
polygon EFGH is Dilated from polygon ABCD
Hence polygon EFGH ≈ polygon ABCD
polygon IJKL is Dilated from polygon ABCD
Hence polygon IJKL ≈ polygon ABCD
As polygon ABCD ≈ polygon IJKL & polygon EFGH
=> polygon EFGH ≈ polygon IJKL
