If ax^3+9x^2+4x-10 when divided by x-3 leaves the reminder 5,then a=​
FinnZ [79.3K]

Let f(x) = ax³ + 9x² + 4x – 10

g(x) = 0⇒x - 3 = 0

⇒ x = 0 + 3

⇒ x = 3

On dividing f(x) by x - 3, it leaves a remainder 5.

Now keeping, f(3) = 5

⇒a(3)³ + 9(3)² + 4(3) - 10 = 5

⇒ a × 27 + 9 × 9 + 4 × 3 - 10 = 5

⇒ 27a + 81 + 12 - 10 = 5

⇒ 81 + 12 - 10 - 5 = 27a

⇒ 81 + 12 - 15 = 27a

⇒ 93 - 15 = 27a

⇒ 78 = 27a

⇒ a = 27/78

⇒ a = 0.3461

What is the difference between the areas of a circular table with diameter 6 ft and a circular table with diameter 8 ft? Round y
MrMuchimi

If the diameter is given in a problem, area is computed as

A = (π/4) × D<span>2   where </span><span>π is equal to 3.14</span>

<span>If D (diameter)  of one circular table is 6 ft its  Area is 28 sq ft.</span>

If D of another circular is 8 ft its Area is 50 sq ft.

<span>The difference between the areas of the two tables is, therefore (50-28) or 22 sq. ft.</span>

X - 5y = 10; (0, -2) Group of answer choices no yes
mr Goodwill [35]
  • Yes, this linear equation is correct on point (0,-2).

Given that:

  • The linear equation

         x - 5y = 10;

  • The point

        (0, -2)

To find

  • We have to prove LHS = RHS

So, according to the question

We have,

The linear equation,

         x - 5y = 10; and point is (0,-2)

From equation,

         x - 5y = 10

Take the left part of given linear equation,

         LHS = x - 5y

Now, putting the values, x = 0 and y = -2.

Then, we will be get.

                = x - 5y

                = (0) - 5 ×(-2)

                = - 5 × -2

                = 10.

So, we can say that

          LHS = RHS.

Where,

           LHS = Left Hand Side.

           RHS =  Right Hand Side.      

We can solve that linear equation in other way,

When we put x = 0, we get y = -2.

So, if we put x = 1, we get y = -9/5.

Similarly, if x = 2, then y = -8/5.

Now, we can say that points (0,-2), (1,-9/5) and (2,-8/5) are lie in the linear equation x - 5y = 10.
