To find the missing value, tan (x) = 7 use the arctan (tan^-1) of 7
arctan(7) = 81.87 degrees
The answer is C.
The sample space of the experiment (i.e. the total number of ways he can pick 7 random pages out of a total of 6 + 4 = 10 pages) is given by:

If he picks at least 5 pages of maths homework, this means that he either picked 5 pages or 6 pages of maths homework.
The number of ways he can pick 5 or 6 maths homework is given by:

Therefore, the probability that he recovers at least 5 pages of his math homework is given by:
Answer:
okay
vertex:(2,4)
domain: (-∞,∞)
range: [4,∞)
Step-by-step explanation:
to find the vertex from the equation
f(x) = (x − 2)² + 4
an easy way is to use the numbers given. so the vertex of this equation is x= 2 (because it is always the opposite of itself in the equation) and y= 4 because the point is going up 4.
to find domain is easy. domain is on the x-axis so the equation is a parabola so it has to points at the same direction. therefore it has a domain that goes from negative infinity to positive infinity.
lastly to find range, which is on the y-axis is to find from where the parabola starts and is pointing, either up or down. in this equation the vertex, which is also the starting point starts at 4 and continues to go on- to infinity.
ps i hope this helps.
I'm pretty sure this is what you have to do;
v=-16-47v
add 47v on the other side of the equal sign
47v=-16
then divide 47 on each side of the equal sign
47v÷47v=1v or just v
-16÷47=-0.3
v=-0.3
I think this is right.
Hope this helps
