Answer:
4^2 / px3 = 2/3
Step-by-step explanation:
4^2 / px3 = 4^2 / 8 *3
= 4*4 / 8*3
= 4/ 2*3
= 2/3
Answer:
2^-6.
Step-by-step explanation:
64 = 2^6
so 1/64 = 1 / 2^6
= 2^-6.
Answer:
add 33 to both sides
Step-by-step explanation:
Given
-
x - 33 = 33 ( add 33 to both sides )
-
x = 66 ( multiply both sides by - 2 to clear the fraction )
x = - 132
Answer:
BC = 5.87
Step-by-step explanation:
Reference angle = 50°
Side Opposite to reference angle = 7
Adjacent side = BC = ?
Apply trigonometric function, TOA, thus:
Tan 50 = Opp/Adj
Tan 50 = 7/BC
BC × Tan 50 = 7
BC = 7/Tan 50
BC = 5.87369742 ≈ 5.87 (nearest hundredth)
Answer:
A
Step-by-step explanation:
The first answer is correct because we have a decay factor.
The sample is losing mass, so the number that is being multiplied by a power of x must be less than 1.
If the second answer were used, then the sample would be gaining mass.
