I could be wrong here but I’m pretty sure the answer is
P(0.15) because 0.75 x 0.2 is 0.15

P(x)=Third-degree, with zeros of −3, −1, and 2, and passes through the point (1,12).

Mila [183]

Answer:

The polynomial is:

$p(x) = -x^3 - 2x^2 + 5x + 6$

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots $x_{1}, x_{2}, x_{n}$ such that it can be written as: $a(x - x_{1})*(x - x_{2})*...*(x-x_n)$ , in which a is the leading coefficient.

Zeros of −3, −1, and 2

This means that $x_1 = -3, x_2 = -1, x_3 = 2$ . Thus

$p(x) = a(x - x_{1})*(x - x_{2})*(x-x_3)$

$p(x) = a(x - (-3))*(x - (-1))*(x-2)$

$p(x) = a(x+3)(x+1)(x-2)$

$p(x) = a(x^2+4x+3)(x-2)$

$p(x) = a(x^3+2x^2-5x-6)$

Passes through the point (1,12).

This means that when $x = 1, p(x) = 12$ . We use this to find a.

$12 = a(1 + 2 - 5 - 6)$

$-12a = 12$

$a = -\frac{12}{12}$

$a = -1$

Thus

$p(x) = -(x^3+2x^2-5x-6)$

$p(x) = -x^3 - 2x^2 + 5x + 6$

The storage place of a truck is in the shape of a rectangular prism it is 6 feet wide 20 feet long and 6 feet tall how many cubi

Nesterboy [21]

Answer:

The truck can hold 720 cubic feet of cargo.

Step-by-step explanation:

We are given the following in the question:

Dimensions of storage place of truck:

Width, w = 6 feet

Length, l = 20 feet

Height, h = 6 feet

We have to find the volume of the storage place.

Volume of storage place = Volume of rectangular prism

$V=w\times l\times h$

Putting values, we get,

$V = 6\times 20\times 6\\V = 720\text{ cubic feet}$

Thus, the truck can hold 720 cubic feet of cargo.

Anyone know what i did wrong for this problem?

Naddika [18.5K]

Answer:

I think that instead of the x beside the 5 (5x) it has to be a g. cuz in the next section it says: Answer for g variable. (g =...)

so instead of: 48 + 5x = 68.50

try: 48 + 5g = 68.50

hope it helps! have a good rest of ur day!
