A ball is thrown into the air with an upward velocity of 48 ft/s. Its height h in feet after t seconds is given by the function
Masja [62]
The equation modeling the height of the ball at time,t is given by h=-16t²+48t+6
<span>a. In how many seconds does the ball reach its maximum height?
Time taken for the ball to reach the maximum height will be given by:
h'(t)=-32t+48=0
finding the value of t we get:
32t=48
t=48/32
t=1.5 seconds
Thus the time taken for the ball to reach the maximum time is 1.5 seconds

b]</span><span> What is the ball’s maximum height?
The maximum height will be:
h(1.5)=-16(1.5)</span>²+48(1.5)+6
h(1.5)=42 fee

Your teacher divides the class into two groups of the same size by picking names at random from the class, and you will be in gr
slega [8]

Answer:

C. as likely as not

Step-by-step explanation:

The teacher makes two groups with the same number and divides the student at random. The two groups have equal size, so the chance for someone to get picked into group 1 is 100%/2= 50%. The chance for someone to get picked into group 2 will be also 100%/2= 50%

The chance to get picked to be in group 1(50%) is the same as the chance to NOT get picked into group 1(50%). The word to explain this chance will be "as likely as not".

. A rowing club has 600 members. 60% of them are women. After 200 new members joined the club, the percentage of women was reduc
valkas [14]

Answer:

40

Step-by-step explanation:

Given:

Initial number of members = 600

Percentage of women = 60\%\ of\ 600=0.60\times 600=360

Now, members added = 200

So, total number of members after addition = 600 + 200 = 800

Percentage of women out of 800 members = 50\%\ of\ 800=0.50\times 800 =400

Increase in women = New number of women - Old number of women

Therefore, increase in women = 400 - 360 = 40

So, 40 women are there in the 200 new members that joined the club.
