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

Y varies inversely with x. When x = 3 then y = 5. Write a function to represent this relationship.
Mariulka [41]

Answer:

<em>The function to represent this relationship will be:  y= \frac{15}{x}</em>

Step-by-step explanation:

y  varies inversely with  x. That means......

y= \frac{k}{x}..............................(1)  

where k is a proportional constant.

Given that, when x=3, then y=5

Plugging these values into the above equation, we will get.....

5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k

Now plugging this k=15 into equation (1).....

y= \frac{15}{x}

So, the function to represent this relationship will be:  y= \frac{15}{x}
