3 0

Answer:

  • 34.714 seconds

Step-by-step explanation:

<u>According to the question we have:</u>

  • Formula h = - 16t + s
  • h = 0
  • s = 555.427 ft
  • t = ?

<u>Substitute the given values and solve for t:</u>

  • 0 = - 16t + 555.427
  • 16t = 555.427
  • t = 555.427/16
  • t = 34.714

Rational numbers are closed under addition ,multiplication but not closed under division

Rational number

Closure property

assume two rational numbers say x and y. the results  of addition and multiplication operations give a rational number we can say that rational number are closed under addition and multiplication . For example

rational number are not closed under division as  1 and 0 are rational number  but 1/0 is not defined but it is closed under addition  and multiplication

that is 1+0 = 1 closed under addition

          1*0 =0 closed under multiplication

but 1/0  is not defined so it is not closed under division

Hence Rational numbers are closed under addition ,multiplication but not closed under division

Find the final amount of money in an account if $7, 200 is deposited at 2.5 % interest compounded
andreev551 [17]

The final amount is $7,615.27

A = P(1 + r/n)^t

Where,

A = Final amount

P = principal = $7, 200

r = interest rate = 2.5% = 0.025

n = number of periods = 4

t = time = 9 years

A = P(1 + r/n)^t

= 7,200(1 + 0.025/4)^9

= 7,200(1 + 0.00625)^9

= 7,200(1.00625)^9

= 7,200(1.0576769512798)

= 7,615.2740492152

Approximately,

A = $7,615.27

Find the scale factor where the pre-image is the small triangle and the image is the large triangle.
allsm [11]

Scale factor is the ratio of two corresponding sides.

Here we have two triangles, where the preimage is the smaller triangle and the image is the larger triangle.

So scale factor =14/18 = 7/9

And to find the missing variable, we need to set the ratio.

7/9 = 28/x

Cross multiplying both sides

7x = 28*9

x = 36
