The function d(s) = –5s – 15 models the depth, in feet, of a rock that Dante dropped into a lake s seconds after he lost sight o

Ne4ueva [31]

Answer:

The x-intercept will tell you how many seconds have passed before Dante lost sight of the rock.

Step-by-step explanation:

The problem specifies that the function d(s) will model the depth in feet of a rock that Dante dropped into a lake s seconds after he lost sight of the rock.

In this case we are using an s instead of the x, so the x-intercept will represent a given time. We can find the x-intercept by setting the function equal to zero, like this:

-5s-15=0

when solving for s we get:

$-5s=15$

$s=-\frac{15}{5}$

s=-3

This means that Dante dropped the ball into a lake 3 seconds before he lost sight of the rock. This is what the negative stands for, some time in the past.

So the x-intercept tells us the time it took for Dante to lost sight of the rock.

Find the TWO integers whos product is -12 and whose sum is 1

konstantin123 [22]

Answer:

$\rm Numbers = 4 \ and \ -3.$

Step-by-step explanation:

Given :-

The sum of two numbers is 1 .
The product of the nos . is 12 .

And we need to find out the numbers. So let us take ,

First number be x
Second number be 1-x .

According to first condition :-

$\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}$

Hence the numbers are 4 and -3
