Answer:
x = π/12, π/4, 3π/4, 11π/12, 17π/12, 19π/12
Step-by-step explanation:
sin(4x) cos x − sin x cos(4x) = √2 / 2
Use angle difference formula.
sin(4x − x) = √2 / 2
sin(3x) = √2 / 2
3x = π/4 + 2kπ, 3π/4 + 2kπ
x = π/12 + 2kπ/3, π/4 + 2kπ/3
x = π/12, π/4, 3π/4, 11π/12, 17π/12, 19π/12
Well, i find it helps to turn the fractions into decimals.
3 3/4 = 3.75
5 1/8 = 5.125
so now subtract:
5.125 - 3.75 = 1.375
so that means it weighs 1.375 ounces more each week
so then take the second week (5.125) and add on 1.375
5.125 + 1.375 = 6.5
now to convert that into a fraction (lowest terms) it would be:
6 1/5 ounces
Therefore,
Jarett's puppy will weigh 6 1/5 ounces at three weeks old.
Hope this helps and ave a great day! :D
Answer:
slope (m) = 4
y-intercept (b) = -2
Step-by-step explanation:
25% because 21 is a quarter of 84. And 21 times 4= 84, so 21 is 25% of 84.
