For P(x) = 2x^4 – 5x^3+x-10, use synthetic substitution to evaluate P(-2). P(1), and P(2).
marusya05 [52]

Answer:

P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10

= 2(16) - 5(-8) + (-2) - 10

= 32+40-2-10

= 60

P(1) = 2(1^4) - 4(1^3) + (1) - 10

= 2 - 4 + 1 - 10

= -11

P(2). = 2(2^4) - 5(2^3) + (2) - 10

= 2(16) - 5(8) + 2 - 20

= 32-40+2-10

= -20

The length of a rectangle is 5 times the width. If the area is 500 square feet, then what is the length of the rectangle, in fee
tester [92]

Answer:

The length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.

Step-by-step explanation:

Since the length of a rectangle is 5 times the width, to determine the length of the rectangle if the area is 500 square feet, the following calculation must be performed:

Area = Base x height

500 = X x 5X

500/5 = X x X

100 = X x X

100 = 10 x 10

X = 10

Thus, the length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.

Does anybody know this ?
Aleonysh [2.5K]

Answer:

0, 1, 2, 3, 4

Step-by-step explanation:

Multiply each x value by 1/3 then add 2. Since the numerator is 1, you would multipy by one and divide by the denominator of 3, so you really need to divide each x value by 3 then add 2.

-6:

-6/3 = -2

-2 + 2 = 0

-3:

-3/3 = -1

-1 + 2 = 1

0:

0/3 = 0

0 + 2 = 2

3:

3/3 = 1

1 +2 = 3

6:

6/3 = 2

2 + 2 =4
