The perimeter of a rectangle is 48 m. The width of the rectangle is 2 more than half the length. Find the length and the width
Ksivusya [100]

Answer:

Length = 14.6667

Width = 9.33333

Step-by-step explanation:

let the length be x

Width = (x/2)+2

Perimeter = 2(L+W)

Perimeter = 2(x+(x/2+2)) =48

2[(3/2)x + 2] =48

3x+4= 48

3x = 44

x =14.666667

width = (14.666667/2)+2

Width = 9.333333

For this assignment, you will create a presentation to explain the additive and multiplicative
Mekhanik [1.2K]
Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30

additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0

so x+3-3=10-3
x+0=7
x=7

Find dy/dx and d2y/dx2, and find the slope and concavity (if possible) at the given value of the parameter. (If an answer does n
ella [17]

Answer:

The slope of the function is  ²/₃ and since the second derivative is zero, the concavity doesn't exist.

Step-by-step explanation:

Given;

x = 6t

y = 4t - 3

point t = 4

\frac{dy}{dx} = (\frac{dy}{dt} )/(\frac{dx}{dt} )=\frac{\frac{dy}{dt} }{\frac{dx}{dt}} \\\\\frac{dy}{dt}  = 4; \frac{dx}{dt} = 6\\\\\frac{dy}{dx} =\frac{4}{6} = \frac{2}{3}

The slope of the function is  ²/₃

take the second derivative of the function;

the second derivative will be zero since the first derivative is a constant value.

\frac{d^2y}{dx^2} = 0

Since the second derivative is zero, the concavity doesn't exist.
