Jeff hikes 1/2 mile every 15 minutes,or 1/4 hour.Lisa hikes 1/3 miles every 10 minutes, or 1/6 hour.How far do they each hike in 1 hour ?2 hour?
Answers
Answer: They hike 30 miles and 20 miles in 1 hour respectively and they hike 60 miles and 40 miles in 2 hours respectively.
Step-by-step explanation:
Since we have given that
Number of mile Jeff hikes in every 15 minutes =
As we know that
1 hour = 60 minutes
So, number of mile Jeff hikes in every 1 hour =
number of miles Jeff hikes in every 2 hours =
Number of miles Lisa hikes in every 10 minutes =
Number of miles Lisa hikes in every 1 hour =
Number of miles Lisa hikes in every 2 hours =
Hence, they hike 30 miles and 20 miles in 1 hour respectively and they hike 60 miles and 40 miles in 2 hours respectively.

The equation of a circle is:
( x - h )² + ( y - k )² = radius²
Therefore, in this example,
( x + 4 )² + ( y - 6 )² = 25
25 = radius²
radius = 5
Final answer:
The equation you provided is a standard form equation for a circle. By comparing it to the general circle equation and taking square root of the constant on the right side, we find that the radius of the circle is 5.
Explanation:
The equation of a circle is typically given in the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius.
- Looking at your given equation: (x + 4)² + (y - 6)² = 25, we can see that this fits the general form.
- The radius r is given by the square root of the number on the right side of the equation. In this case, it equals to √25 which is 5.
Therefore, the radius of the circle is 5.

Plan B: Put the $1,000 in an account that pays 5 percent interest per year.
Which statement is true?
Plan A will be worth more than plan B after two years.
Plan A will be worth the same amount as plan B after one year.
Plan B will be worth more than plan A after three years.
Plan B will be worth more than plan A after four years.
Answers
Plan A = 1000 dollars to be invested in an account that pays 100 dollars per year. (1000 + 100 = 1100 dollars in a year)
Plab B = 1000 dollars to be invested in an account that pays 5% interests per year (1000 * .05 = 50 => 1000 + 50 = 1050 dollars per year)
Thus the correct answer is Plan A will be worth more than plan B after two years.
The true statement is Plan A will be worth more than plan B after two years.
What is the worth of the plans with the passage of time?
The equation that can be used to represent the future value of plan A:
Total value = initial value x ($100 x number of years)
Value in 2 years: 1000 x (100 x 2) = $1200
Value in 3 years: 1000 x (100 x 3) = $1300
Value in 4 years: 1000 x (100 x 4) = $1400
The equation that can be used to represent the future value of plan B:
FV = P (1 + r)^n
- FV = Future value
- P = Present value
- R = interest rate
- N = number of years
- Value in 2 years: 1000 x(1.05^2) = $1102.50
- Value in 3 years: 1000 x(1.05^3) = 1157.63
- Value in 4 years: 1000 x(1.05^2) = 1215.51

because S(x,y) = (x, 1/2y), reverse what is done to y and simplify,
y = x^3 > y = 1/2*x^3 to compress vertically,
because S(x,y) = (x-7,y), reverse what is done to x,
y = 1/2*(x+7)^3 to shift to the left,
reflection across the x-axis changes positives to negatives,
y = -1/2(x+7)^3 to reflect across the x-axis.
