Answer:
Step-by-step explanation:
115% = 115/100 = 1.15
of means multiply
1.15 * 95 = 109.25
Answer:
Since YS is an angle bisector, ∠XYS=∠SYZ
∠SYZ= 34.2°
∠XYZ= 34.2+34.2=68.4°

Answer:
2,674.14 g
Step-by-step explanation:
Recall that the formula for radioactive decay is
N = N₀ e^(-λt)
where,
N is the amount left at time t
N₀ is the initial amount when t=0, (given as 42,784 g)
λ = coefficient of radioactive decay
= 0.693 ÷ Half Life
= 0.693 ÷ 18
= 0.0385
t = time elapsed (given as 72 years)
e = exponential constant ( approx 2.7183)
If we substitute these into our equation:
N = N₀ e^(-λt)
= (42,787) (2.7183)^[(-0.0385)(72)]
= (42,787) (2.7183)^(-2.7726)
= (42,787) (0.0625)
= 2,674.14 g
Answer:
Option B is correct, i.e. 1.
Step-by-step explanation:
The Discriminant of quadratic equation is given as follows:-
D = b² -4ac
When D is ZERO and the quadratic formula is simplified as follows:-
x = ( -b ± √(b² -4ac) )/2a
x = ( -b ± √D )/2a
x = ( -b ± √(0) )/2a
x = ( -b ± 0 )/2a
x = -b/2a
So x has one real root with multiplicity 2.
Hence, option B is correct, i.e. 1.
