Answer:
2 seconds and 38 seconds
Step-by-step explanation:
h=-16t²-vot
1,200=-16t²-640t
turn this into standard form
16t²-640t+1200=0
now plug thes numbers into the quadratice formula
a 16 b -640 c 1200
solve with quadratic formula to get ≅2 and ≅38 seconds
Answer:
This could be correct in the case and only if k would equal 24.5 so only in that case
Step-by-step explanation:
So if you're driving 25 miles per hour, it would take you 7 hours to drive 175 miles.
175 miles ÷ 25 miles = 7 hours.
As an inequality, you'd say , because there's a closed circle (meaning we'll have "or equal to") and the shading goes to the right (meaning we also want numbers greater than -11).
In interval notation, you first describe where the interval starts on the left and ends on the right. This starts at -11 and goes on forever, so we'll say it goes to infinity. Then you have to indicate if each end is included.
- The -11 has a solid dot, so -11 is included (again, that's we had "or equal to" before), so we'll put a square bracket on that.
- Infinity is not a number. It's an idea. Since it's not a number, it cannot be included, so it'll get a curved parenthesis.
The interval notation answer is:
Answer:
ab is 68 units and midpoint is -24
Step-by-step explanation:
its just simple addition and subtraction
