He should add exact since money is involved
he could also estimate since they are so close together, but he would be off only 2 cents
A
D) x = 2y^2, because you find the inverse by switching the x and y in the equation, so y = 2x^2 --> x = 2y^2
To simplify even further, you get
x/2 = 2y^2/2 --> y^2 = x/2
--> y = +/- sr(x/2)
Answer:
Step-by-step explanation:
i dont now but thank for the points of this answer jaja because you are so bad in mathematics its so easy sorry if i write this not good because a speak spanish hola this is hello in spanish
Given that the half life of 3H is 12.3 years.
The amount of substance left of a radioactive substance with half life of
after t years is given by
Therefore, the number of years it will take for 18% of the original tritinum to remain is given by
Therefore, the number of <span>years that the time could be read at night is 30.4 years.</span>
Answer:
78°
Step-by-step explanation:
From the diagram,
Applying sine rule,
SinA/a = sinC/c................... Equation 1
Given: c = 29 cm, C = 50°, a = 37 cm
Substitute into equation 1 and solve for A.
sinA/37 = sin50°/29
sinA = (37×sin50°)/29
sinA = (37×0.766)/29
sinA = 28.34/29
sinA = 0.9774
A = sin⁻¹(0.9774)
A = 77.8°
A ≈ 78°
Hence the measure of angle A = 78°
