Art [367]

f(x)=4x^3 - 6x^2 + 2x - 5

f(-2)

Replace X with -2:

4(-2)^3 - 6(-2)^2 + 2(-2) - 5 =

Calulate the powers:

4(-8) - 6(4) +(-4) -5=

Multiply:

-32 - 24 -4 -5=

Answer:

Step-by-step explanation:

Take the area of the yard and subtract from it the area of the pool. In quadratic form, the area of the pool is

$2x^2-x-28$

Subtracting the area of the pool from the area of the yard:

$3x^2-14x-5-(2x^2-x-28)$

Since the negative in front of the parenthesis will change the signs inside:

$3x^2-14x-5-2x^2+x+28$

Combine like terms to get the area left after the pool goes in:

$x^2-13x+23$

Okay HELP i have to questions in one problem.

Answer:

1) To calculate length of fringe, we need to find the perimeter

The question does not clearly say how much is length and width

Assuming length = 245 and width = 234 inches

P = 2(length + width)

P = 2 ( 245 + 234)

P = 2 (479)

P = 958 inches

2) To calculate length of fringe, when length is increased by 33 inches

P = 2 ( l + w)

P = 2 (278 + 234)

P = 2 x 512

P = 1024 inches

Answer:

$s=-4.905*t^{2} +20*t+120$

The equation corresponds to a quadratic function.

Step-by-step explanation:

Given

$s=-\frac{1}{2} gt^{2} +v_{0} t+s_{0}$

where

$g=9.81\frac{m}{s^{2} }\\ v_{0}=20\frac{ft}{s} \\ s_{0} =120 ft$

the function that describes the height of Joan’s basketball is

$s=-\frac{1}{2} (9.81\frac{m}{s^{2} })t^{2} +20\frac{ft}{s}*t+120 ft\\ s=-4.905*t^{2} +20*t+120$

The equation corresponds to a quadratic function.
