Using the law of sines:
Sin(angle) = Opposite leg / hypotenuse (A to C)
Sin(63 degrees) = 15 ft / A to C
A to C = 15 / sin(63)
A to C = 15 * cosec 63 degrees.
The answer is D
<h3><u>(f - g)(x) = -2x^2 + 10x</u></h3>
x^2 + 6x - 1 - (3x^2 - 4x - 1)
Distributive -1 to each term in parentheses.
x^2 + 6x - 1 - 3x^2 + 4x + 1
Combine like terms.
-2x^2 + 10x
To calculate what is asked we use the formula for radioactive decay. It is expressed as follows:
An = Ao (e^(-kt))
We calculate as follows:
An = Ao (e^(-kt))
74 = 100 (e^(-k(10)))
k = 0.0301
1/2 = (e^(-0.0301t))
t = 23 hours
Hope this answers the question.
You will need to show all the answers that are at 25 or less.
Please see the attached paper for the inequality and the graph of the possible solutions.
A filled in circle means to include that value.
