When the polynomial P(x)=ax^3+bx^2+3x-10 is divided by x+1, the remainder is -8. P(x) has a factor of x+5. Find the values of a
Ahat [919]

Answer:

a = 1, b = 6

Step-by-step explanation:

The equation given is as follows;

P(x) = a·x³ + b·x² + 3·x - 10

The above equation has a factor of x + 5, therefore, we have;

P(-5) = 0 = a·(-5)³ + b·(-5)² + 3·(-5) - 10

-125·a + 25·b + (-15) - 10 = 0

-125·a + 25·b - 25 = 0

-125·a + 25·b  = 25...........(1)

Also, we are given that;

a·x³ + b·x² + 3·x - 10 divided by x + 1 as a remainder, R = -8, therefore;

P(-1) = -8 = a·(-1)³ + b·(-1)² + 3·(-1) - 10

-a + b - 13 = -8

-a + b = -8 + 13 = 5

-a + b = 5............................(2)

Multiply equation (2) by 25 and subtract from (1) gives

-125·a + 25·b - 25(-a + b) = 25 - 25×5

-100·a = 25 - 125 = -100

a = 1

Therefore, from equation (2) we have;

-1 + b = 5

b = 5 + 1 = 6.

What is the sum of the fractions? Use the number line and equivalent fractions to help find the answer. Negative three-fourths +
Brums [2.3K]

Answer:

-3/4 + 1/2 = -1/4

Step-by-step explanation:

Think of it this way; We know that 1/2= 2/4

so the equation could be modeled like this

-3/4+2/4= ?

we have to add the negative and positive number like so

the answer would be = -1/4 or -0.25

What is the solution to the system of equations? {10x^2 - y = 48 2y = 16x^2 + 48
julsineya [31]
A graph shows the solutions to be
  (x, y) = (-6, 312) or (6, 312)


To solve algebraically, remove a factor of 2 from the second equation and use that expression to substitute for y in the first equation.
  10x^2 -(8x^2 +24) = 48
  2x^2 = 72
  x = ±√(72/2) = ±6
  y = 8*36 +24 = 312

How can i solve this?
o-na [289]

Answer:

16π   (units squared)

Step-by-step explanation:

Picture a full circle with radius 8.  The area of this full circle is A = πr².

Now substitute 8 for r:  We get A = π(64) = 64π.

Now multiply this result by 1/4 to obtain the area of the figure shown:

A = (1/4)64π = 16π   (units squared)
