Answer: -1

Step-by-step explanation:

The equation is given in slope-intercept form. Slope-intercept form is y=mx+b, where m is slope, and b is y-intercept. Since m is slope, we know that it is -1.

Describe the end behavior of the function. f(x)=x^3+11x^2+35x+30

Lelechka [254]

To determine end behavior, we only have to look at the leading term.

First, the leading term is positive, so we won't have to negate anything.

The leading term has a power that is odd.

Since the exponent is odd, this means that the function goes to positive infinity as x goes to positive infinity.

This also means that the function goes to negative infinity as x goes to negative infinity.

Those are the end behaviors.

Have an awesome day! :)

A die is a cube with 1 edgemeasuring 0.62 inches. Find the total volume of the 5 dice in agame.

igomit [66]

The volume of one die is the edge to the power of 3:

$V=0.62^3in^{3^{}}.$

The total volume is five times the above volume:

$5V=1.19164in^3.$

Answer:

$1.19164in^3$

Learning Task 4. Solve the problem by applying the sum and product of roots

Delvig [45]

Answer:

<em>Thus, the dimensions of the metal plate are 10 dm and 8 dm.</em>

Step-by-step explanation:

For a quadratic equation:

$x^2+bx+c=0$

The sum of the roots is -b and the product is c. Note the leading coefficient is 1.

We know the perimeter of the rectangular metal plate is 36 dm and its area is 80 dm^2. Being L and W its dimensions, then:

P=2(L+W)=36

A=L.W=80

Note both formulas are closely related to the roots of the quadratic equation, we only need to adjust the data for the perimeter to be exactly the sum of L+W and not double of it.

Thus we use the semi perimeter instead as P/2=L+W=18

The quadratic equation is, then:

$x^2-18x+80=0$

Factoring by finding two numbers that add up to 18 and have a product of 80:

$(x-10)(x-8)=0$

The solutions to the equation are:

x=10, x=8

Thus, the dimensions of the metal plate are 10 dm and 8 dm.
