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.
In this question, there are numerous information's of immense important already given. Based on those given information's the answer to the question can be easily deduced.
Ratio of the perimeter of two rectangles = 4:7
Perimeter of the larger rectangle = 42 inches
Let us assume the common ratio = x
Then
7x = 42
x = 42/7
= 6
Then
Perimeter of the smaller rectangle = 4 * 6 inches
= 24 inches.
So the perimeter of the smaller rectangle is 24 inches. I hope the procedure and the answer is clear enough for you to understand. Based on this procedure, you can attempt similar problems without requiring any outside help.
Regina has enough money to buy all the items she needs
3 cans of dog food = 1.50*3 = 4.50
1 gallon of milk = 4.00*1 = 400
5 pounds of chicken = 1.55*5 = 7.75
1 box of cereal = 2.75*1 = 2.75
6 rolls of paper towels = .99*6 = 5.94
If you add all those together it equals 24.94 leaving 6 cents in change
4.50 + 4.00 + 7.75 + 2.75 + 5.94 = 24.94$

If the problem is referring to the equivalent logarithmic equation log (20 *27).
We can easily find and solve its equivalent expression using one of the many identities available in logarithmic.
We can have the expression:
log (20*27) = log 20 + log 27
