In a book about birds, there is a drawing of a sea eagle that shows a wingspan of 2.8 cm. If the book says the scale is 1:90, what is the actual wingspan of the sea eagle.
Answer:
2.52
The domain of the function is the range of values of x that can be used to be replaced in the equation for it to become true. We are given that the value of f(x) should range only from -1 to 3. We evaluate each of the choices and see if the values of f(x) will fall within the range.
(a) -12; f(x) = 2^(-12) - 10 = -9.9999 (NOT AN ANSWER)
(b) -10; f(x) = 2^(-10) - 10 = -9.999 (NOT AN ANSWER)
(c) -9; f(x) = 2^(-9) - 10 = -9.999 (NOT AN ANSWER)
(d) -6; f(x) = 2^(-6) - 10 = -9.98 (NOT AN ANSWER)
(e) -2; f(x) = 2^(-2) - 10 = -9.75 (NOT AN ANSWER)
Hence, none of the choices will allow the value of f(x) to fall between -1 and 3.
1.994 x 10^-23
-0.167 x 10^-23
1.827 x 10^-23
Correct answer is the second one.
Answer:
true
Step-by-step explanation:
your answer is correct
You bought 12 cards on Monday and 24 on Tuesday. If you add these together, you will have <em>36 baseball cards in total. </em>
You decided to give some cards (x) to your brother. You now have 13 baseball cards left.
36 - (x) = 13.
36 - 13 = (x).
Therefore, (x) must equal 23 cards given to your brother.
I hope this helps!
