2x-7=29
"Seven less than" => minus 7.
"Two times <u>a number</u>" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together,
-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)
The length of the island will be given as follows:
tan θ=opposite/adjacent
thus:
tan75.8= 3000/a1
a1=3000tan75.8
a1=11855.885 ft
also:
tan15.6=3000/a2
a2=3000tan15.6
a2=837.62 ft
Thus the length of the island will be:
11855.885-837.615
=11,018.24 ft
10^7 is the correct answer
Answer: 36cm
Step-by-step explanation:
Answer:
Option a.
Step-by-step explanation:
By looking at the options, we can assume that the function y(x) is something like:


such that, y(0) = √4 = 2, as expected.
Now, we want to have:

replacing y' and y we get:

Now we can try to solve this for "a".

If we multiply both sides by y(x), we get:


We can remove the x factor in both numerators if we divide both sides by x, so we get:

Now we just need to isolate "a"


Now we can subtract a*x^2 in both sides to get:

Then the solution is:

The correct option is option a.
