Ok, to prove the two triangles, we need reasoning:
1) the side AC is common (as you can see, both triangles share the side AC)
2) angle DCA is equal to angle BAC (this is due to alternate angles)
3) angle BCA is equal to angle DA (again, this is due to alternate angles)
Answer:
<em>The population on 30th day will be </em><em>134836</em><em>.</em>
Step-by-step explanation:
This is a case of exponential growth. The general form of exponential function is,
where, a and b are constants.
The data points from the question are 
Putting the values in the function,
for 
----------1
for 
------2
Dividing equation 2 by 1,
Putting the value of b in equation 1,
Now the function becomes,
Putting x=30, we get
Answer:
x=3
Step-by-step explanation:
To solve for x in the given equation,follow the steps below.
2-(3x-4)=2x-9
clear bracket
2-3x+4=2x-9
6-3x=2x-9
collect like-terms
2x+3x=6+9
5x=15
divide bothsides by 5
Answer:
c. (A + B)^2-A^2 + 2AB + B^2
Step-by-step explanation:
Given that:
a.
(A-B)^2 = A^2 - 2AB + B^2
If and only if AB = BA
Then;
(A-B)^2 = (A -B ) (A - B)
(A-B)^2 = A^2 - AB-BA + B^2 (FALSE)
b.
(AB)^2=A^2B^2
on true if any only if AB =BA
(AB)^2= (AB) (AB)
c.
(A+ B)^2 = A^2 + 2AB + B^2
(A+ B)^2 = (A + B) (A+B)
(A+ B)² = A × A + A × B + B × A + B × B
(A+ B)^2 = A^2 + A*B + B*A + B^2
This is true
