Answer:
Step-by-step explanation:
The height y of an angled ladder, x ft from its base is given by the formula
To find the formula for x in terms of y, first express ax:
If divide the previous equation by a:
The formula for the general sin function is
where b is the period and c is the phase shift. We are given a period of
and the formula to solve for b is
. We set up to solve for b:
. Cross multiply to get
and b = 8. Now for the phase shift. The formula for that is -c/b, and since we already know b, and we have a phase shift value of pi/2, we solve for c:
and
. Therefore,
. Putting all that together into the equation with the A value of 6, we have
. Factoring out the 8 then, the final equation is
, third choice down.
3. 24.96 and 140.8
4. 30 and 87.5
P=(9-7(.75))/(.38)
p=(9-5.25)/.38
p=3.75/.38
p=9.86
"Pieces" are integers so only 9 pieces .38yd are cut
Answer:
it should be the second one
Step-by-step explanation:
the only reason i kno this is because one side always has to be white
hope this helps
sorry if its wrong
