First we use sin(a+b)= sinacosb+sinbcosa
and cos(a+b)=cosa cosb -sinasinb
tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)
and sin(x+pi/2) = sinxcospi/2 + sinpi/2cosx =cosx,
<span>cos(x+pi/2) = cosxcospi/2- sinxsinpi/2= - sinx,
</span> because <span>cospi/2 =0, </span>and <span>sinpi/2=1
</span><span>=tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)= cosx / -sinx = -1/tanx = -cotx
</span>from where <span>tan(x+pi/2)=-cotx</span>
Quotient is another name for the answer to a division problem
the hundreds place is the 3rd number before the decimal, 9999999.0
^this one
so you need to find a division problem that equals something between 100 and 999
1000 divided by 10 is a good one, the answer to that problem is 100, and 100 has its first digit in the hundreds place.
Equation: 50 is greater than or equal to 45 + .5(x)
x = amount of pictures you can send without going over your budget
subtract 45 from both sides. you are left with: 5 is greater than or equal to .5(x)
multiply both sides by 2. you are left with: 10 is greater than or equal to x
Answer: 10 is greater than or equal to x
