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:
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.
The height of trapezoid is 18 yards
<em><u>Solution:</u></em>
Given that, trapezoid has an area of 342 square yards
The length of one base is 17 yards, and the length of the other base is 21 yards
To find: height of trapezoid
<em><u>The area of trapezoid is given by formula:</u></em>
Where "h" is the height
"a" and "b" are the length of base
Here given that,
area = 342 square yards
a = 17 yards
b = 21 yards
h = ?
<em><u>Substituting the values we get</u></em>,
Thus height of trapezoid is 18 yards
Answer:
x = (10 - b) / a
Step-by-step explanation:
ax + b = 10
ax = 10 - b
x = (10 - b) / a
Answer:
100000
Step-by-step explanation:
You multiple 125000 with .20 you get 25000 then you subtract 25000 fro 125000 and you get 100000 and that's your answer.
