amp;Substitute h=19.
amp;Subtract 19.5 on both sides.
amp;Solve for t using the Quadratic Formula.
amp;Simplify.
amp;Subtract.
amp;Evaluate the root.
amp;Find the two solutions.
The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25
0.75≤t≤3.25
A beaker measure large volumes of liquids and shows the approximate measurement and is not a suggested tool for measuring precise measurements of liquid. A graduated cylinder measures the precise reading of the liquid and is the suggested tool for a exact measurement.
Hope this helps :)
Trigone of the urinary bladder is made from three orifices, two <span>ureteric orifice and one urethra orifice.
Ureteric orifice is made by ureter from the left and right kidney. It's the place where urine enters the bladder.
Urethra orifice is connected to urethra and it's where the urine comes out of the bladder.</span>
