Write into a single logarithm log b (X+1)+ log b (X-8)

1 answer:

3 0

To solve, use properties of logs, specifically log(u)+log(v)=log(uv). This makes your equation logb(x+1)+logb(x-8)=logb((x+1)(x-8)), which can be made into logb(x^2-7x-8) by expanding the factored form.

The point P(5,1) lies on the curve y=5x. If Q is the point (x,5x), find the slope of the secant line PQ for the following values

sveta [45]

Answer:

Step-by-step explanation:

We have been given that the point $P(1,5)$ lies on the curve $y=5x$ . Q is the point $(x,5x)$ . We are asked to find the slope of the secant line $PQ$ for $x=5.1$ .

Let us find y-coordinate corresponding to $x=5.1$ for point P as:

$y=5(5.1)=25.5$

Now, we will use slope formula to find required slope.

$m=\frac{y_2-y_1}{x_2-x_1}$

Let point $(1,5)=(x_1,y_1)$ and point $(5.1,25.5)=(x_2,y_2)$ .

Using these points in slope formula, we will get:

$m_{PQ}=\frac{25.5-5}{5.1-1}=\frac{20.5}{4.1}=5$

Therefore, the slope of the line PQ is 5.

Convert 5.45787878... to a fraction. Simplify.

kondaur [170]

5.45787878 = 545787878/100000000

divide both numerator and denominator by 2 or any other number

545787878 ÷ 2 = 272893939

100000000 ÷ 2 = 50000000

272893939/50000000 is your answer
