4. figure A is a trapezoid the parallel sides are the bases and the other sides are the legs.
5. sum of interior angles is 360 to find the other answer subtract all known angles from 360.
6. figure B is a parallelogram. if angles are congruent that means they have the same measure. so if angle 1 is 128 then and 4 is 128.
7. the definition of a square : all interior angles each measure 90 degrees.
8. nonconsecutive means they aren't next to each other so in figure D angles d and b and angles a and c for figure E angle j and m and angle n and l
9. figure e is concave that means its got an angle that "caves in"
Answer:
The value of C is 2.
Step-by-step explanation:
What you do when you are dividing exponents like that you just minus them.
It says x^3/x. It basically means 3-1.
Your answer is 2.

Answer:
y = 0.2·0.5^x
Step-by-step explanation:
An exponential function is generally of the form ...
y = a·b^x
where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.
In the given table, y = 0.2 for x = 0, so a = 0.2.
We find that the value for x = 1 is 0.1, so the value of b is ...
b = 0.1/0.2 = 0.5
Then the exponential function is ...
y = 0.2·0.5^x
Given
Your family has a circular swimming pool.
The radius of the pool is 9 feet and and its depth is 4 feet.
Find out the volume of the pool.
To proof
As depth is given in the question that means the shape of the swimming pool
is cylinder.
Formula

where r = radius
h = height
now
radius of the pool is 9 feet and and its depth is 4 feet.
put all the values in the above equation
we get

use 3.14 to approximate pi

we get
= 1017.4 ( approx )feet²
Hence proved
