Answer:
Step-by-step explanation:
Given:
Length of ladder, y = 10 ft
θ = π/3 rad
Using cosine rule,
Sin θ = opposite/hypotenuse
Sin θ = x/y
Sin θ = x/10
Differentiating both sides with respect to dθ,
10 × cos θ × dθ = dx
10 cos θ = dx/dθ
dx/dθ = 10 × cos π/3
= 5 ft/radians.
Answer:
8m+4n
Step-by-step explanation:
4(2m+n)
you have to distribute 4 to 2m and n
so your answer will be
8m+4n
Hope this helped :))
Hey there!
Since we weren't given any probabilities based on the chance of rain after it rained the day before, we can assume the probability will stay the same. We can disregard "If it rains today...".
If it rains 290 days out of the year (365 days), there will be a 290/365 chance of rain of a particular day. You can divide 290 by 365 to get a 79% chance.
Hope this helped you out! :-)
Divide 90 by 1.3 and you will get your answer.
Do it yourself! just follow instructions!
