D: {0, 1, 2, 3}
R: {−3, −2, 2, 5}
The relation is a function.
That's the answer.
Tan(E) = 6/8 =3/4
tan(E) (opposite side)/(adjacent side)
Answer: Hi!
To find the answer for question 24, we would first find the square root of 20 and 5. The square root of 20 is about 4.47 (I used a calculator for convenience) and the square root of 5 is about 2.24. Now we need to add these:
4.47 + 2.24 = 6.71
Now we divide 30 by this:
30/6.71 = 4.47
Now, we'll evaluate the answer choices.
a) is equal to 1.49
b) is equal to 13.4
c) is equal to 4.47
d) is equal to 26.88
The answer choice that is correct is c, because it is what we got for the problem that we were supposed to solve in the beginning.
Hope this helps!
When the 10 is to a negative power you move the decimal to the left. in this case its 5 spots. i believe your answer is .00005003
Volume of cylinder:
V = πr²h
The desired volume is 1 Liter = 1000 cm³
1000 = πr²h
h = 1000/πr²
Surface area of cylinder:
S.A = 2πr² + 2πr²h
We substitute the value of h from the first equation:
S.A = 2πr² + 2πr(1/πr²)
S.A = 2πr² + 2/r
Now, to minimize surface area, we differentiate the expression with respect to r and equate to 0.
0 = 4πr - 1000/r²
4πr³ - 1000 = 0
r = 4.3 cm
h = 17.2 cm
