Answer:
Using properties of parallelogram and angle sum property of a triangle in the figure as shown below in the attachment
In parallelogram ABCD, AC is a diagonal.
Given: 
and 
As, we know that opposite angles in parallelogram are equal.
therefore,
Now, in ΔADC
Sum of the measures of angles in a triangle is 180 degree.
Substituting the values of 
and we have;
or
Subtract 
from both sides we get
Therefore, the measure of angle CAD is 
.
36x^2-49
this closely matches the binomial formula of (a+b)*(a-b)=a^2-b^2
so we know:
a^2=36x^2
a=6x
b^2=49
b=7
so (a+b)*(a-b)=(6x+7)*(6x-7)=36x^2-49
Answer:
The rate of change is -0.75
Step-by-step explanation:
For each unit of <em>t</em> the volume of water is decreasing by 0.75.
At <em>t</em>=13.333 the volume of water is 0. at <em>t</em>=0 the volume of water is 10
Hope this helps
Answer:
12 1/2
Step-by-step explanation:
2 x 5 = 10
1/2 x 5 = 2 1/2
10 + 2 1/2 = 12 1/2
