The parent functions are defined with all coefficients with value 1.
They can be linear, quadratic, cubic, absolute, reciprocal, exponential, logarithmic, square root, sine, cosine, tangent...
Then we can pick a function and transform it in order to include the point (-1,5) in the function definition.
We will use the quadratic parent function:
We will adjust the coefficient a of the quadratic function in order to include (-1,5)
Then, our transformed function is:
Answer:
10 miles per hour.
Step-by-step explanation:
Let x represent athlete's walking speed.
We have been given that her jogging rate is 5 mph faster than her walking rate, so athlete's jogging speed would be miles per hour.
10 minutes = 1/6 hour.
20 minutes = 1/3 hour
While walking, we will get
While jogging, we will get
Since athlete is covering same distance while walking and jogging, so we can equate both expressions as:
Cross multiply:
Therefore, athlete's walking speed is 5 miles per hour.
Jogging speed:
Therefore, athlete's jogging speed is 10 miles per hour.
I would say screw it and use the calculator anyway
Children's books cover the most shelf space in the store.
Mysteries = 3/10
Travel = 25%
children = 7/20
Based on the problem, the total number of shelves in the bookstore is 20.
Therefore:
Mysteries = 3 / 10 * 20 = 6 shelves
Travel = 25% * 20 = 5 shelves
Children = 7/20 * 20 = 7 shelves
Total shelves occupied by the three types of stories is 18.
Children's books cover the most shelf space in the store.
