The projectile motion of an object is modeled by the function h (t) = -16t2 + vt + c, where v is the initial velocity of the obj

yarga [219]

The function represents the height of the object after t seconds is

$h(t)=(-16)t^{2} +(59)t +6$

Step-by-step explanation:

The projectile motion of an object is modeled by the function

$h(t)=(-16)t^{2} +vt +c$

where, v is the initial velocity of the object,

c is the initial height of the object,

t represents the time the object is in motion.

Given that v=59 ft/s and intial height is h(0)=6 ft

h(0)=6 ft

h(0)= $(-16)(0)^{2} +v(0) +c$

h(0)=c

So, c= 6

Therefore, The function represents the height of the object after t seconds is

$h(t)=(-16)t^{2} +(59)t +6$

Answer: Bradley is $1\dfrac{22}{185}$ times as heavy as Ricardo.

Step-by-step explanation:

Given : The weight of Bradley = 207 pounds

The weight of Ricardo = 185 pounds

To find : Bradley is how many times as heavy as Ricardo?

For this , we divide "weight of Bradley " by "weight of Ricardo" , we get

$207\div 185 =\dfrac{207}{185}$

Since 207 and 185 have no common factors , so it is the simplified way .

Further , we can convert it into mixed fraction as : $\dfrac{207}{185}=1\dfrac{22}{185}$

Hence, Bradley is $1\dfrac{22}{185}$ times as heavy as Ricardo.

Sue has 100 dimes and quarters. If the total value of the coins is $21.40, how many of each kind of coins does she have?

Nookie1986 [14]

Answer:

There would be 24 dimes and 76 quarters.

Step-by-step explanation:

In order to find this, start by defining the number of dimes by x and the number of quarters as y. Now we can create a system of equations. Make the first about the total number of coins.

x + y = 100

Make the second about the amount of money.

.10x + .25y = 21.40

Now we can solve using elimination by multiplying the second equation by -4 and adding through.

x + y = 100

-.40x - y = -85.60

-----------------------

.60x = 14.4

x = 24

Now we can use the amount of dimes we have to find the number of quarters.

x + y = 100

24 + y = 100

y = 76
