monthly
The balance after 10 years is $

Answers

Step-by-step explanation:

step 1. let's call the balance A, the initial amount P, the yearly rate r, the number of compounds yearly n, and the time t.

step 2. A = P(1 + r/n)^(nt) (compounding equation)

step 3. A = 8500(1 + .0178/12)^((12)(10))

step 4. A = 8500(1.00148334)^120

step 5. A = $10,154.68.

A toy rocket lifts off at an initial velocity of 102 feet per second from a height of 10 feet. The height of the rocket can be modeled by the equation h = – 16t2 + 102t + 10, where ‘t' is the time in seconds. When will the rocket hit to the ground?

Answers

Answer:

6.47secs

Step-by-step explanation:

Given the height of the rocket modelled by the equation;

h = – 16t^2 + 102t + 10, where ‘t' is the time in seconds

The rocket will hit the ground at h = 0

Substitute into the equation

– 16t^2 + 102t + 10 = 0

Multiply through by -1

16t^2-102t-10 = 0

t = 102±√(102)²-4(16)(-10)/2(16)

t = 102±√10404+640/32

t = 102±√11044/32

t = 102 ±105.09/32

t = 102+105.09/32

t = 207.09/32

t = 6.47secs

Hence it will take 6.47secs for the rocket to hit the ground

What is the Area and Perimeter for tbe rectangle?

Answers

Given :-

length of rectangle = ( 4n-5 )

breadth of rectangle = ( 3n-2)

To find :-

Area and perimeter of rectangle.

solution :-

by the question ,

We know the area of rectangle = length × breadth

Area = (4n -5) (3n-2)

[tex] = {12n}^{2} - 8n - 15n + 10[/tex]

[tex] = {12n}^{2} - 23n + 10[/tex]

now ,

perimeter = 2 ( length + breadth (

= 2 ( 4n-5 + 3n-2)

= 2 ( 7n-7)

= 14n -14

Consider the following passage:The first and most manifest way is the argument from motion. It is certain and evident to our senses that some things are in motion. Whatever is in motion is moved by another.... For 'motion' means the reduction of something from a state of potentiality into a state of actuality. But a thing can be reduced from a state of potentiality into a state of actuality only by something already in a state of actuality.... It is impossible for the same thing should be simultaneously in a state of actuality and potentiality from the same point of view, but only from different points of view.... Therefore, whatever is in motion must be put in motion by another, and that by another again. This cannot go on to infinity, because then there would be no first mover, and, consequently, no other movers--since subsequent movers only move insofar as they are put in motion by the first mover.... Therefore it is necessary to arrive at a first mover, put in motion by no other; and this everyone understands to be God.The following question has 2 parts:Please formalize the argument presented in this passage.Please present your one best criticism of the argument presented in the passage If you could plz help it would be greatly appreciated.
