How would you factor out 8w-6w^3?? I have a math test tomorrow and went completely blank. :(

The GCF here would be 2w, so divide each one by that. Now just divide by that, and multiply the quantity (amount in the parenthesis) by 2w so we don't have a different equation than the original. Now you have your answer: 2w(4w-3w^2)

Find the line integral of f(x, y) = y e^X^2 along the curve r(t) = 3t i - 4t J, -2 lessthanorequalto t lessthanorequalto -1. The
Semenov [28]

\vec r(t)=3t\,\vec\imath-4t\,\vec\jmath

\implies\left\|\dfrac{\mathrm d\vec r(t)}{\mathrm dt}\right\|=\|3\,\vec\imath-4\,\vec\jmath\|=\sqrt{3^2+(-4)^2}=5

The line integral of f(x,y) along the curve C parameterized by \vec r(t) is

\displaystyle\int_Cf(x,y)\,\mathrm ds=\int_{-2}^{-1}f(3t,-4t)\left\|\dfrac{\mathrm d\vec r(t)}{\mathrm dt}\right\|\,\mathrm dt=-20\int_{-2}^{-1}te^{9t^2}\,\mathrm dt

Substitute u=9t^2 so that \mathrm du=18t\,\mathrm dt. Then

\displaystyle\int_Cf(x,y)\,\mathrm dS=-\frac{20}{18}\int_{36}^9e^u\,\mathrm du=\frac{10}9\int_9^{36}e^u\,\mathrm du=\boxed{\frac{10}9(e^{36}-e^9)}

A whale weighs 4 tons. A great white shark weighs 10,200 pounds. How many
slavikrds [6]

Answer:

<em>C: The shark weighs 2200 pounds more than the whale.</em>

Step-by-step explanation:

So you have to remember first that one ton is equal to 2,000 pounds. Then, we convert tons to pounds (for the whale) to get 4(2,000)=8,000 pounds. So, the whale weighs 8,000 pounds. The shark weighs 10,200 pounds, so all you have to do now is do 10,200-8,000 to get 2,200 pounds.  So, the answer is C.

I need help please. Thanks!
Karolina [17]

Answer:

A

Step-by-step explanation:

We are given the function f and its derivative, given by:

f^\prime(x)=x^2-a^2=(x-a)(x+a)

Remember that f(x) is decreasing when f'(x) < 0.

And f(x) is increasing when f'(x) > 0.

Firstly, determining our zeros for f'(x), we see that:

0=(x-a)(x+a)\Rightarrow x=a, -a

Since a is a (non-zero) positive constant, -a is negative.

We can create the following number line:

<-----(-a)-----0-----(a)----->

Next, we will test values to the left of -a by using (-a - 1). So:

f^\prime(-a-1)=(-a-1-a)(-a-1+a)=(-2a-1)(-1)=2a+1

Since a is a positive constant, (2a + 1) will be positive as well.

So, since f'(x) > 0 for x < -a, f(x) increases for all x < -a.

To test values between -a and a, we can use 0. Hence:

f^\prime(0)=(0-a)(0+a)=-a^2

This will always be negative.

So, since f'(x) < 0 for -a < x < a, f(x) decreases for all -a < x < a.

Lasting, we can test all values greater than a by using (a + 1). So:

f^\prime(a+1)=(a+1-a)(a+1+a)=(1)(2a+1)=2a+1

Again, since a > 0, (2a + 1) will always be positive.

So, since f'(x) > 0 for x > a, f(x) increases for all x > a.

The answer choices ask for the domain for which f(x) is decreasing.

f(x) is decreasing for -a < x < a since f'(x) < 0 for -a < x < a.

So, the correct answer is A.
