Step-by-step explanation:
First, we need to find the unit rate of each animal (how many feet each animal can fly in a second). We do this by dividing the number of feet flown by the number of time.
Bat: 232/4 = 58 ft per second
Hummingbird: 343/7 = 49 ft per second
Based off of this information, we can conclude that the bat can fly faster than the hummingbird.
Answer:
158 cases
Step-by-step explanation:
Given tbe quadratic regression model :
y = -2x^2 + 40x + 8
y = number of cases of a new disease
x = number of years
The predicted number of cases of a new disease in 15 years can be calculated thus ;
Put x = 15 in the equation ;
y = -2(15)^2 + 40(15) + 8
y = - 2 * 225 + 600 + 8
y = - 450 + 600 + 8
y = 158
158 cases
The value of x is about 4.7
