Answer:
Step-by-step explanation:
I think the missing equation in your question is: h(t) = -16 + 16t + 480
Here is my answer:
As we know that the vertex form of a parabola, y=a + k where(h,k) is the vertex
h(t) = -16 + 16t + 480
= -16 ( + 480
= -16 + 484
So the vertex is ( , 484)
a. It take for Joseph second to reach his maximum height
b. The highest point that Joseph reached is the vertex of the function, it is 484 ft
c. Joseph hit the water after how many seconds?
<=> h(t) = 0
<=> -16 + 16t + 480 = 0
<=> t = second = 6 sec
Hope it will find you well
Answer:
Maria had 105 beads at first.
Step-by-step explanation:
Let number of beads Maria have be x.
Let number of beads Farida have be y.
Given:
Maria and Farida has 250 beads altogether.
Hence equation is represented as;
Also Given:
Maria used 18 beads to make a bracket.
hence bead left with maria =
farida gave away 2/5 of her beads.
Hence beads left with Farida =
Also they have the same number of beads left.
bead left with maria = beads left with Farida
Now Multiplying equation 1 with 3 we get;
Now adding equation 2 by equation 3 we get;
we know the value of x = 105
hence substituting value of x in equation 1 we get;
Maria had 105 beads and Farida had 145 beads at first.
Final Answer: Maria had 105 beads at first.
