What is equivalent to 5^3 ( Choose all that apply)

Tema [17]

Answer:

A, and D

Step-by-step explanation:

A works because when you multiply like bases, you add exponents, so we have...

5^7*5^-4 = 5^(7+(-4)) = 5^(7 -4) = 5^3

B doesn't work because when you divide like bases, you subtract the exponent of the denominator from the exponent of the denominator...

5^12/5^4 = 5^(12 - 4) = 5^8

C doesn't work because there is addition.

5 + 5² = 5 + 25 = 30, and 5³ = 125

D works because 5^0 = 1, so we have

5^0(5^3) = 1(5^3) = 5^3

E doesn't work because there is subtraction...

5^3 - 5^0 = 5^3 - 1 = 124

Let PQR be a triangle such that angle P = angle Q + angle R. Among all three exterior angles of triangle PQR, what is the smalle

Phantasy [73]

Answer:

The smaller exterior angle is the exterior angle in the vertex P, and it measures 90°

Step-by-step explanation:

The sum of the internal angles of a triangle needs to be 180 degrees, so we have two equations:

$mP = mQ + mR$

$mP + mQ + mR = 180\°$

Substituting $mQ + mR$ by $mP$ in the second equation, we have:

$mP + mP = 180\°$

$mP = 90\°$

The other two angles need to be lesser than mP, and the exterior angle is the supplement of the internal angle, so the bigger the internal angle, the smaller the exterior angle.

So if the bigger internal angle in this triangle is mP, the smaller exterior angle is also the angle in the vertex P:

$exteriorP = 180\° - mP$

$exteriorP = 90\°$
