10 tripled equals 30 than 40 cut in half is 15 15+5=20 20=20
Evaluate int[sin^3(θ)cos(θ)dθ] with u = sin(θ)
du/dθ = cos(θ), dθ = du/cos(θ)
The integral becomes:
int[u^3•cos(θ)du/cos(θ)]
= int[u^3•du]
= u^4/4 + C
Substitute u = sin(θ) to get back a function of θ:
sin^4(θ)/4 + C
Hey there! :)
Answer:
Choice 4: π/4, 3π4, 7π/4
Step-by-step explanation:
For the values of θ to have the same reference angles, the denominators of the radians must be the same. Therefore:
Choice 1: π/6, π/3, 5π/6 - incorrect. π/3 will have a different reference angle as it has a denominator of 3.
Choice 2: π/3, 5π/6, 4π/3 - incorrect. 5π/6 will have a different reference angle as it has a denominator of 6.
Choice 3: π/2, 5π/4, 7π/4 - incorrect. π/2 will have a different reference angle.
Choice 4: π/4, 3π4, 7π/4 - correct. All of these radians contain the same denominator, and will each have the same reference angles of π/4.
Answer:
8/2
Step-by-step explanation:
So you'll want to multiply the number of keys for each by the number below them. So 2/8 has 4 "x"s, so you'll want to multiply (2/8)*4 and so on.
4*(2/8)=1
4*(3/8)=12/8=>1.5
1*(4/8)=1/2
Add those all up to get 4, which is also 8/2.
Answer:
Our answer is 
.
Step-by-step explanation:
To solve for x, we need to isolate the variable. We can do so by subtracting 2 to both sides.
Our answer is .
To find the decimal, calculate with a calculator.
