Answer:
1) ∫ x² e^(x) dx
4) ∫ x cos(x) dx
Step-by-step explanation:
To solve this problem, eliminate the choices that can be solved by substitution.
In the second problem, we can say u = x², and du = 2x dx.
∫ x cos(x²) dx = ∫ ½ cos(u) du
In the third problem, we can say u = x², and du = 2x dx.
∫ x e^(x²) dx = ∫ ½ e^(u) du
Answer:
97 and 1/8
Step-by-step explanation:
(4 + 7 + 5 + 5 + 2) + (14 5/8 + 14 3/4 + 14 7/8 + 15 + 15 1/8)
23 + (14 5/8 + 14 3/4 + 14 7/8 + 15 + 15 1/8)
23 + 74 1/8
97 and 1/8
So...we can write eqn as
40x = 50(x-1)
so. -10x=-50
so. x=5
therefore .... the distance of 40 lb will be 5 ft ...answer !!!
Answer:
<h2>
</h2>
Step-by-step explanation:
Divide both sides of the equation by 3
Write 7x as a difference
Factor out 3x from the expression
Factor out -4 from the expression
Factor out 2x + 5 from the expression
When the product of factors equals 0 , at least one factor is 0
Solve the equation for X
Move constant to R.H.S and change its sign
Calculate the difference
Divide both sides of the equation by 2
Calculate
Again,
Move constant to RHS and change its sign
Calculate the sum
divide both sides of the equation by 3
Calculate
Hope this helps..

Answer:
(x + 9)
Step-by-step explanation:
<u />
<u>X² + 6 - 27</u>
(x-3)
1. Factor the numerator:
<u>(x-3) (x + 9)</u>
(x-3)
2. cancel the (x - 3) from numerator and denominator
3 Answer left is (x + 9)
