Answer:
t(h)= (h-200)/-4.9
The time to reach a height of 50 meters is 30.6 seconds
Step-by-step explanation:
To express t as a function of height (h) we must transform the equation below:
h=200-4.9t
h-200=-4.9t
(h-200)/-4.9=t
t(h)= (h-200)/-4.9
To find the time to reach a height of 50 meters, we must replace this value on the new equation:
t(h)=50-200/-4.9
t(h)= 30.612
The time to reach a height of 50 meters is 30.6 seconds
Answer:
standard form for a quadratic expression
Step-by-step explanation:
This is a quadratic expression. If you want this expression in standard form, write the terms in descending order of powers of x: -2x^2 + 1.
This -2x^2 + 1 has not yet been factored.
-2x^2 + 1 is in standard form.
Answer:
A. The stepwise selection procedure uses Adjusted R-square as the "best" model criterion.
Step-by-step explanation:
Stepwise regression is a model which uses variables in step by step manner. The procedure involves removal or inclusion of independent variables one by one. It adds the most significant independent variable and removes the less significant independent variable. Usually stepwise selection uses R-square or Mallows Cp for picking the best fit.
Explanation:
The number of Beverages present at the store ;
Soda = 2000ml = 2L
Apple Juice = 2.5L
Fruit Punch = 1.5L
Lemonade = 2L
Now, we have to buy exactly 10 liters but it should be at least one container of each beverage.
Soda + Apple juice + Fruit Punch + Lemonade = 8L
So we need 2 L more.
The only way of doing this is by either having 2 containers of soda or 2 containers of lemonade.
We can conclude that the correct answer is:
Answer:The combination of beverages she can purchase is:Soda = 2 containerApple juice = 1 containerFruit punch= 1 containerLemonade = 1 container
