Systole and Diastole are 2 phases of the cardiac cycle. Systole is when the heart contracts to pump blood out. Diastole is when the heart relaxes after contraction and refills with blood.
For first question, you can let t=1.5 and calculate h=140 ft. For second question, we can change the equation to the form of h=-16[(t-2)^2-9]. So you can see from the equation that the maximum height is created when t=2, equals to 144 ft. For question 3, let h=128. From equation, we can get t=3 or t=1. For last question, the rocket hit the lake means h=0, so t=5 or t=-1(not applicable). So the answer is t=5. You can also draw the graphic for the equation to help.
Answer:
Honestly first get rid of all the negative people around you there will always be that person or persons who don't belive in you. But trust me if you belive in yourself give it your 100% and don't stop grinding. ask people for promotions and don't br afraid to experiment try not to stay on the same idea try, trying something new.
Answer: h= 5/4
Step-by-step explanation:
h - 1/2 = 3/4, to find the value of h:
Step 1: Add 1/2 to both sides of the equation
h = 3/4 + 1/2 (findthe common denominator
h = 5/4
N=7/5=1.4 because if you divide by 5 your answer should be 1.4
