Answer:
The correct choice is:
-2 to the 4th power is positive 16.
Option C is correct.
Step-by-step explanation:
We need to find mistake make in work below:
The mistake here is when we have even power, the negative sign gets positive i.e if m is even
so, in our case it would be:
The correct choice is:
-2 to the 4th power is positive 16.
Option C is correct.
Answer:
explanations: we multiply with a rational surd
(x-9)*√(x+9)/(√(x-9)*√(x+9)
=(x-9)√(x+9)/
B.( x-9)/√x+3 =( x-9)*(√x-3)/(√x+3)*(√x-3)
= (x-9)*(√x-3)/x-9
=√x-3
Answer:
Lowest angle of the triangle with hypotenuse of 2.9ft and a leg of 2.6ft is 26.29°.
Explanation:
A triangle has a hypotenuse of 2.9ft and a leg of 2.6ft
We have smallest angle = Angle C
We have, Cos C = AC/BC
= 2.6/2.9
= 0.897
C = 26.29°
So lowest angle of the triangle with hypotenuse of 2.9ft and a leg of 2.6ft is 26.29°.
