The first equation in the system models the heights in feet, h, of a falling baseball as a function of time, t. The second equat
Masja [62]

Answer:

The height of the baseball is 35 feet at the moment the player begins to leap.

Step-by-step explanation:

We are given equations as:

h(t)=35+16t^2--------(1)

Where h represents the heights in feet, h, of a falling baseball as a function of time, t.

The second equation is given as:

h(t)=6+18t-16t^2-------(2)

Where h represents  the heights in feet, h, of the glove of a player leaping up to catch the ball as a function of time, t.

Hence when at the time of leap i.e. at t=0.

first equation i.e. equation (1) yields h(0)=35 i.e. it represents:

"  The height of the baseball is 35 feet at the moment the player begins to leap "

Hence option: C is correct.

In the expansion of (ax+1)^7<br> the fifth term is 945x^3<br> Find the value of a.
Advocard [28]

Answer:

a = 3

Step-by-step explanation:

First start writing out the binomial expansion of (ax + 1)^7

[1^7] + [7C1 * 1^6 *(ax)] + [7C2*1^5*(ax)^2]+[7C3*1^4*(ax)^3]

as you can see from this, the last bracket will produce our x^3 term

7C3*1^4*a^3x^3 \\35a^3x^3\\35a^3 = 945\\a^3 = 27\\a = 3

Hope this helps, let me know if you have any questions :)

A 2.2 GB game is being downloaded on your laptop. When you have downloaded half a gigabyte, you notice that your computer has be
zhannawk [14.2K]
In this question, you already download 0.5 GB of the total 2.2GB data you need which mean you only need to download 1.7GB left. If the speed of download is 0.01 GB per minute, then the time needed would be:
(2.2GB- 1.7GB) / (00.1GB/minute)= 1.5GB/ (0.01GB/minute)= 150 minute = 2.5 hours

Two hours would not be sufficient to download the data as you need 2.5 hours
