An arithmetic sequence would have a common difference between successive terms, not the case here.

A geometric sequence has a common ratio; let's check:

$\dfrac{1/2}{1/6} = 3$

$\dfrac{3/2}{1/2} = 3$

$\dfrac{9/2}{3/2} = 3$

That's a common ratio of 3 so as far as we can tell a geometric sequence.

A baseball diamond is a square with side 90 ft. A batter hits the ball and runs toward first base with a speed of 31 ft/s. (a) A

Afina-wow [57]

Answer:

13.86 ft/sec

Step-by-step explanation:

If we let x = distance batter has run at time t and D = distance from second base to the batter at time t, then we know $\frac{dx}{dt}=31 ft/s$ and we want $\frac{dD}{dt}$ when he is halfway (at x = 45).

Using Pythagoras theorem

$D^2=90^2+(90-x)^2\\\text{Differentiating with respect to t}\\2D\frac{dD}{dt}=0+2(90-x)(-1)\frac{dx}{dt}\\2D\frac{dD}{dt}=-2(90-x)\frac{dx}{dt}$

When x=45

$D^2=90^2+(90-x)^2\\D^2=90^2+(90-45)^2\\D^2=10125\\D=\sqrt{10125}$

$2D\frac{dD}{dt}=-2(90-x)\frac{dx}{dt}\\2\sqrt{10125}\frac{dD}{dt}=-2(90-45)(31)\\\frac{dD}{dt}=\frac{-2(45)(31)}{2\sqrt{10125}} =-13.86ft/s$

Thus, when the batter is halfway to first base, the distance between second base and the batter is decreasing at the rate of about 13.86 ft/sec.

There are 8 paper clips, 4 erasers and 6 thumbtacks. The number of paper clips is ____the number of erasers. And the number of e

forsale [732]

<span><span>1. </span>Given Data:
=> There are a total of 8 paper clips
=> There are also 4 erasers
=> And there are 6 thumbtacks.
Now, answer the following question
=> The number of paper clips is _____ the number of erasers
Let’s compare
There are 8 paper clips and 4 erasers.
Thus the number of paper clips is twice the number of erasers.
=> The number of erasers is ___ the number of thumbtacks>
There are 4 erasers and 6 thumbtucks.
Thus the number of erasers is 2/3 the number of thumbtucks </span>

Ann is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.

ipn [44]

Answer:

Ans: greater than 40 mileage Company A will charge less than Company B

Step-by-step explanation:

as company A charges a fix amount $93 for any distance and company B charges variable amount starting from $65.there will be a certain mileage after that the amount charged by company B should be greater than company A.

let for greater than m mileage company A will

charge less than company B.

charge for company A for m mileage= $93

charge for company B for m mileage= $65 + $0.70*m

so,

93 ≤ 65+0.70*m

93-65 ≤ 65+0.70*m -65

28 ≤ 0.70*m

28*10 ≤ 7 *m

280 ≤ 7m

280/7 ≤ 7m/7

40 ≤ m
