The answers are MK and PY and AH.
Answer: 
Step-by-step explanation:
You need to remember the mulplication of signs:
Knowing this, you can distributive the negative sign. Then you get:
Now you need to add the like terms. Then:
Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:
H = - 16 t² + 36 t + 10
The maximum height of the ball is at the vertex of the parabola.
t = - b / 2 a
t = -36/-32
t = 1.12 s
The maximum height of the ball:
h max = - 16 * 1.12² + 32* 1.12 + 10 = - 16 * 1.2544 + 35.84 + 10 =
= - 20.0704 + 45.84 = 25.7696 = 25.77 m
Answer:
0.28
Step-by-step explanation:
Given in question that,we have to decrease by 72%.that means from 100% of total, 72% should be decreased. that means an overall of 28% will be left. so if you make a number into 28% of it, it implies that you have decreased that number by 72%.so from this,we can say that we have to make the number 28%.that means we have to multiply the number with 28/100 which is equal to 0.28.
F and E are congruent with the figure above
