Answer:
false statement
Step-by-step explanation:
5+x^2=2x^2+13
5+x^2-2x-13=0
-8+x^2-2x^2=0
-8-x^2=0
-x^2=8
x^2=-8
this statement is false for any value of x because the power function with an even exponent is always postive or 0
Answer:
40.82 is the surface area of this solid.
Answer:
$28360
Step-by-step explanation:
Step one:
Given data
P=20000
rate= 6%
time= 6years
Step two:
compound interest
A=P(1+r)^t
substitute
A=20000(1+0.06)^6
A=20000(1.06)^6
A=20000*1.418
A=$28360
We know that
see the picture to better understand the problem
in the right triangle ABC
Applying the Pythagoras Theorem
AB²=BC²+AC²-------> BC²=AB²-AC²
AB=8 ft
AC=4 ft
BC²=8²-4²-----> BC²=48--------> BC=√48-------> BC=6.93 ft
the answer is6.93 ft
