3 0

Answer:

10

Step-by-step explanation:

This means that 12/(2x+1)=8/(x+4). Cross multiply to get 16x + 8 = 12x + 48. Subtract 12x + 8 from both sides to get 4x = 40, so x = 10.

What is the volume of a cylinder with base radius 222 and height 666? either enter an exact answer in terms of \piπpi or use 3.1
Leno4ka [110]

In this question, it is given that the base radius is 2 , height is 6 and the value of pi is 3.14 .

And we have to find the volume of the cylinder, and for that, we have to use the following formula

V = \pi r^2 h

Substituting the values of pi,r and h, we will get

V = 3.14(2)^2 * 6 = 75.36 \ cubic \ units

If (x^2 - 1) is a factor of ax^4 + bx^3 + cx^2 + dx + e, show that a + c + e = b + d = 0
alisha [4.7K]
x^2-1=x^2-1^2=(x-1)(x+1)

If x²-1 is a factor of the polynomial, both x-1 and x+1 are factors of it.

According to the remainder theorem, if a binomial x-a is a factor of a polynomial p(x), then p(a)=0.

If x-1 and x+1 are factors of the polynomial p(x)=ax⁴+bx³+cx²+dx+e, then p(1)=0 and p(-1)=0.

p(1)=a \times 1^4+b \times 1^3 + c \times 1^2+ d \times 1+e \\&#10;p(-1)=a \times (-1)^4 + b \times (-1)^3 + c \times (-1)^2 + d \times (-1)+e \\ \\&#10;p(1)=a+b+c+d+e \\&#10;p(-1)=a-b+c-d+e \\ \\&#10;p(1)=0 \\&#10;p(-1)=0 \\ \\ \hbox{add both equations:} \\&#10;a+b+c+d+e=0 \\&#10;\underline{a-b+c-d+e=0} \\&#10;2a+2c+2e=0 \\&#10;2(a+c+e)=0 \\&#10;a+c+e=0 \\ \\&#10;\hbox{substitute 0 for a+c+e in the first equation:} \\&#10;a+b+c+d+e=0 \\&#10;(a+c+e)+b+d=0 \\&#10;0+b+d=0 \\&#10;b+d=0 \\ \\&#10;\boxed{a+c+e=b+d=0} \\&#10;\hbox{proved } \checkmark
