Ingrid hit a golf ball. The height of the ball (in meters above the ground) t seconds after being hit is modeled by h(t)=-5t^2+3

valina [46]

Answer:

1) h(t) = -5(t-3)^2

2) The ball reaches the highest point at 3 seconds.

Step-by-step explanation:

OK. So for this question, I recommend to rewite using vertex form since the answer is given in a more concise manner than using factored.

First Step:

h(t) = -5t^2+30t

= -5(t^2-6t)

= -5(t^2-6t+9)+45

= -5(t-3)^2+45

Second Step:

The vertex form reveals the vertex to be at (3, 45).

Therefore, the ball reaches the highest point at 3 seconds.

Answer:

n = -8

Step-by-step explanation:

5+n/8=4

Subtract 5 from each side

Our class has 50 students. Assuming that no students are born on leap days (February29), what is the probability that no two stu

madreJ [45]

Answer: a) $\dfrac{799}{31250}$ b) $\dfrac{30451}{31250}$

Step-by-step explanation:

Since we have given that

Number of days in a year = 365

Number of students = 50

Probability that no two students share the same birthday. It means each student has different birthday.

Probability(no two students share the same birthday) $=\dfrac{365-1}{365}\times \dfrac{365-2}{365}........\times \dfrac{365-50}{365}$

Probability(no two students share the same birthday) $=\dfrac{^{365}P_{50}}{365^{50}}$

Probability(no two students share the same birthday) $=\dfrac{799}{31250}\approx 0.025568$

Probability that at least one of the students has the same birthday as another student in the class is given by

$1-P(\text{no student share the same birthday})\\\\=1-\dfrac{799}{31250}\\\\=\dfrac{30451}{31250}=0.974432$
