If p(x)= 2x3+ a x2+ 3x–3 and f(x) = x3 + x2-4x+ aleave the same remainder when divided by x-2, find the value of a.
Luda [366]

Answer:

a = 3

Step-by-step explanation:

p(x) = 2x^{3} + ax^{2} +3x -3\\f(x) = x^{3} + x^{2} - 4x + a

To get the remainder when these polynomials are divided by x - 2, subsitute(x = 2) into both functions.

p(2) = 2(2^{3}) + a(2^{2}) +(3*2) -3\\p(2) = 19 - 4a\\f(2) = 2^{3} + 2^{2} - (4*2) + a\\f(2) = 4 + a

Since the remainders are the same, p(2) = f(2)

19 - 4a = 4 + a

19 - 4 = a + 4a

15 = 5a

a = 15/5

a = 3

What will be the surface of 20in 3.75 in and 12,5in
Darina [25.2K]

Answer:

How do I calculate surface area?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

De 1 kg de queso se utilizaron 1/5 gramos para hacer una pizza y ½ para una tarta ¿Cuántos gramos de queso quedaron? ¿Existe más
Mumz [18]

Answer:

Se usaron 700 g de queso, quedando 300 g de queso.

Step-by-step explanation:

Si se usó 1/5 más 1/2 de queso, el total usado fue:

\frac{1}{5}+\frac{1}{2}=\frac{7}{10}    

Entonces, se usó 7/10 del kg inicial de queso. Sabiendo que:

1 kg      ------ 1000 g

7/10 kg ------ x g

Entonces x = 700 g, lo que significa que se usaron 700 g de queso, quedando 300 g de queso.

Este problema se puede resolver utilizando una regla de tres, como se hizo aquí, o mefiante razones, en una equacion lineal.

Espero te haya sido de ayuda!
