You and your friend are in a canoe race. Your friend is a half mile in front of you and paddling 3 miles per hour. You are paddling 3.4 miles per hour. You are 8.5 miles from the finish line. How long will it take to catch up to your friend?
Answer:
To catch your friend you have to paddle for 1.25 hours
Step-by-step explanation:
Your friend is 0.5 mile in front of you and paddling 3 miles per hour. You are paddling 3.4 miles per hour.
Since the speed is the relationship between the space traveled by an object and the time used for it, then the distance is defined as:
distance= speed*time
Being x the time it takes to reach your friend, then your friend's position will be:
3miles per hour*x + 0.5 (since your friend is 0.5 mile in front of you)while your position is:
3.4 miles per hour*xWhen you reach your friend the position of both should be the same. So:
3*x + 0.5= 3.4*x
Solving:
0.5= 3.4*x - 3*x
0.5= 0.4*x
0.5 ÷0.4= x
1.25= x
This means that to catch your friend you have to paddle for 1.25 hours

Step 1: Define
11(4 - 6y) + 5(13y + 1) = 9
Step 2: Solve for y
Distribute: 44 - 66y + 65y + 5 = 9Combine like terms: -y + 49 = 9Isolate y term: -y = -40Isolate y: y = 40Step 3: Check
Plug in y into the original equation to verify it's a solution.
Substitute in y: 11(4 - 6(40)) + 5(13(40) + 1) = 9Multiply: 11(4 - 240) + 5(520 + 1) = 9Subtract/Add: 11(-236) + 5(521) = 9Multiply: -2596 + 2605 = 9Add: 9 = 9Here we see that 9 does indeed equal 9.
∴ y = 40 is the solution to the equation.

What is Luis's average velocity over the 95 s period?
Answer:
Velocity = 0
Speed = 0.84
Step-by-step explanation:
Khan Academy
Luis's average velocity over the 95 sec period is 0 m/s.
Given that, Luis walks 40 m toward his truck. He notices he forgot his keys, so he returns back to his house.
What is the average velocity?Magnitude of average velocity is always less than or equal to the average speed because displacement is always smaller than or equal to distance.
Average Velocity = Total time / Total Displacement
It is a vector quantity and has units of m/s.
Here, total time = 95 sec and displacement = 0 meter
Now, average velocity = 95/0
= 0 m/s
Therefore, Luis's average velocity over the 95 sec period is 0 m/s.

The shape of a garden is rectangular in the middle and semi circular

Т.
of this garden [Length of rectangle is
7m 20-(3.5 +3.59 metres).

DI
20 m
Answer:
[tex]Area = 129.5m^2[/tex]
[tex]Perimeter = 48m[/tex]
Step-by-step explanation:
Given
See attachment
Required
Determine the area and the perimeter of the garden
Calculating Area
First, we calculate the [tex]area\ of\ the\ rectangle[/tex]
[tex]A_1 = L * B[/tex]
Where:
[tex]L = 20-(3.5 +3.5)[/tex]
[tex]B = 7[/tex]
So:
[tex]A_1 = (20 - (3.5 + 3.5)) * 7[/tex]
[tex]A_1 = (20 - 7) * 7[/tex]
[tex]A_1 = 13 * 7[/tex]
[tex]A_1 = 91[/tex]
Next, we calculate the area of the two semi-circles.
Two semi-circles = One Circle
So:
[tex]A_2 = \pi r^2[/tex]
Where
[tex]r = \frac{7}{2}[/tex]
[tex]A_2 = \frac{22}{7} * (\frac{7}{2})^2[/tex]
[tex]A_2 = \frac{22}{7} * \frac{49}{4}[/tex]
[tex]A_2 = \frac{22}{1} * \frac{7}{4}[/tex]
[tex]A_2 = \frac{22*7}{4}[/tex]
[tex]A_2 = \frac{154}{4}[/tex]
[tex]A_2 = 38.5[/tex]
Area of the garden is
[tex]Area = A_1 + A_2[/tex]
[tex]Area = 91 + 38.5[/tex]
[tex]Area = 129.5m^2[/tex]
Calculating Perimeter
First, we calculate the perimeter of the rectangle
But in this case, we only consider the length because the widths have been covered by the semicircles
[tex]P_1 = 2 * L[/tex]
Where:
[tex]L = 20-(3.5 +3.5)[/tex]
So:
[tex]P_1 =2 * (20-(3.5 +3.5))[/tex]
[tex]P_1 =2 * (20-7)[/tex]
[tex]P_1 =2 * 13[/tex]
[tex]P_1 =26[/tex]
Next, we calculate the perimeter of the two semi-circles.
Two semi-circles = One Circle
So:
[tex]P_2 = 2\pi r[/tex]
Where
[tex]r = \frac{7}{2}[/tex]
[tex]P_2 = 2 * \frac{22}{7} * \frac{7}{2}[/tex]
[tex]P_2 = \frac{2 * 22 * 7}{7 * 2}[/tex]
[tex]P_2 = \frac{308}{14}[/tex]
[tex]P_2 = 22[/tex]
Perimeter of the garden is
[tex]Perimeter = P_1 + P_2[/tex]
[tex]Perimeter = 26 + 22[/tex]
[tex]Perimeter = 48m[/tex]

Answer:
x = 0.05
x = 1.57
Step-by-step explanation:
The given equation is:
[tex]e^x-\ln 2x = 3.7[/tex]
Moving all terms to the left side:
[tex]e^x-\ln 2x - 3.7=0[/tex]
Now we define a function:
[tex]y=f(x)=e^x-\ln 2x - 3.7[/tex]
The solutions of the equation are the values of x such that y=0.
Since the function cannot be solved by algebraic methods, we use a graphing tool.
Those points where the graph crosses the x-axis are solutions of the equation.
Please refer to the graph in the figure below.
We can clearly identify there are two solutions at
x = 0.05
x = 1.57

Normal vision is called 20-20 vision. These numbers are actually a ratio—a comparison of the distance you can see to the distance a normal-sighted person can see. For example, a person with 20-30 vision can see from a distance of 20 feet what a person with 20-20 vision can see from a distance of 30 feet. Based on this knowledge, explain what the following numbers mean regarding vision.
a. 20-100
b. 20-40
A person with 20-40 vision can see up to 30 feet and a person with 20-100 vision can see up to 200 feet (No-one can see that far unless they are not human or unless they are a spirit.)
