Answer:
The x- coordinates are equal at -3.
Step-by-step explanation:
The ball hits the ground when the height h(t) = 0 , so
-16t^2 + 80t = 0
-16t(t - 5) = 0
t- 5 = 0 or -16t^2 = 0 ( here t = 0 which corresponds to when ball is thrown)
t - 5 = 0 gives:-
t = 5 seconds (answer)
Answer:
4
Step-by-step explanation:
This equation is in a reversed form of slope-intercept, or y=mx+b. In this form, b is the y-intercept and in the equation b is equal to 4 and the slop is 2!
You need to know the order of operations (PEMDAS)
Parentheses
Exponents
Multiplication AND Division
Addition AND Subtraction
So look at the equation. Are there exponents? No. Are there parentheses? No. What about multiplication and division? Yes, so you do these first.
3×6=18
So now you have 3-18+3
Now you have to do addition and subtraction (Left to Right)
3-18=-15
Now you have -15+3
-15+3=-12
-12 is your answer.
120 cupcakes
Even # rows
Odd # columns
12: 1, 2,3,4,6, 12 (integers?)
I see only one arrangement with odd column & even rows
3 columns, 40 rows
That's mainly because 120 is an even number.
