Answer: -64

Step-by-step explanation:

h(t) = -16t² + 128t

dh/dt = -32t + 128

At t = 4,

dh/dt= -16(4)² + 128 = 0

At t = 4, dh/dt = 0

At t = 8,

dh/dt = -16(8)² + 128 = -128

At t = 8, dh/dt = -128

The rate of change of h is constant, the average rate change is

(0 - 128) / 2 = -64

We are interested in the dimensions of a certain square. A rectangle has a length of 5 units more than the side of the square an
JulijaS [17]
Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2

and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 = ( x^{2} +5x)/2 <- equation1
Area of square = Side* Side= x*x = x^{2}  <- equation2

As per given data, Equation1 and equation 2 are equal
so 
( x^{2} +5x)/2 = tex] x^{2} [/tex]  
x^{2} +5x = 2 x^{2}
2 x^{2} -  x^{2}   = 5x
x^{2}  = 5x
x = 5

So the side of square = 5 units  

For Square, both dimensions are equal.

Z+(z-6)-2=-10<br> work out the problem and show it to me
Akimi4 [234]

Answer:

z = - 1

Step-by-step explanation:

z + (z - 6) - 2 = - 10 ← remove the parenthesis on left side

z + z - 6 - 2 = - 10 , that is

2z - 8 = - 10 ( add 8 to both sides )

2z = - 2 ( divide both sides by 2 )

z = - 1

A collection of coins consists of nickels, dimes, and quarters. There are
iragen [17]

Answer:

  • 9 nickels
  • 12 dimes
  • 6 quarters

Step-by-step explanation:

We are given relations between the number of each kind of coin and the number of quarters. So, it is convenient to write an equation in terms of the number of quarters.

Let q represent the number of quarters. The number of nickels is 3 more than that, so is (q+3). The number of dimes is 6 more than the number of quarters, so is (q+6). The total value of the coins, in cents, is ...

  5(q +3) +10(q +6) +25q = 315

  40q +75 = 315 . . . . . . . . . . . . . . collect terms

  40q = 240 . . . . . . . . . subtract 75

  q = 6 . . . . . . . . . divide by 40

  q +3 = 9 . . . . number of nickels

  q +6 = 12 . . . number of dimes

There are 9 nickels, 12 dimes, and 6 quarters in the collection.
