Answer:

Perimeter, P = (24d+0.8) cm

Step-by-step explanation:

Given that,

Width of rectangle, B = (4.4d−4.3) cm

Length, l = (7.6d+4.7)

Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,

Perimeter = 2(L+B)

P = 2[(7.6d+4.7)+(4.4d−4.3)]

Collecting like terms

P = 2[(7.6d+4.4d)+(4.7−4.3)]

P=2(12d+0.4)

⇒ P = 24d+0.8

So, the expression for the perimeter of the rectangle is (24d+0.8) cm.

Using two or more complete sentences, describe how you can find a vector parallel to (-3,2).
Tomtit [17]

Answer:

by multiplying any non-zero scalar number except 1 to given vector

Step-by-step explanation:

Scalar multiple of one vector is parallel to the vector.

So in given case, v1= (-3,2) and a vector, v2 parallel to it can be find by multiplying any non-zero scalar number except 1 to v1

i.e

v2= n*v1

n is any scalar non-zero number except 1

let n=2 (one of many possible options)

v2= 2*(-3,2)

   =(-6,4) !

A European bond has a par value of 1000 Euros, a coupon rate of 4.5 percent and a yield to maturity of 3.2 percent. The bond has
Katyanochek1 [597]

Answer:

Bond Price​= 1,182.96

Step-by-step explanation:

Giving the following information:

Par value= 1,000

Cuopon= 1,000*0.045= 45

YTM= 3.2%

Number of years (n)= 10

<u>To calculate the price of the bond, we need to use the following formula:</u>

Bond Price​= cupon*{[1 - (1+i)^-n] / i} + [face value/(1+i)^n]

Bond Price​= 45*{[1 - (1.032^-19)] / 0.032} + [1,000 / (1.032^19)]

Bond Price​= 633.31 + 549.65

Bond Price​= 1,182.96

Determine whether or not f is a conservative vector field. If it is, find a function f such that f = ∇f. (if the vector field is
Likurg_2 [28]

A function assigns the values. The function f = xy²-2x² satisfies a conservative vector field F = ∇f.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given F(x,y) = (y² - 4x) i + 2xy j, and it is needed to be known that,

f_x(x,y)=y^2-4x\\f_y(x,y) = 2xy

Let's look for a primitive of y²-4x with regard to x. Because we regard y (and y²) as constants, a primitive of y² is xy², just as a primitive of k is xk (because we treat y² as a constant). Because a primitive of x equals x²/2, a primitive of 4x is 2x². As a result, a primitive of y²-4x is xy²-2x². We can get any other primitive by adding constants, but because we considered y as a constant, we have that.

f(x,y) = xy²-2x²+c(y)

where c(y) only depends on y (thus, it is constant respect with x).

To learn more about c(y), we shall deduce the formula in terms of y.

2xy=f_y(x,y)

      =\dfrac{d}{dy}(xy^2-2x^2+c(y))\\\\=2xy-0+\dfrac{d}{dy}c(y)\\\\=2xy+\dfrac{d}{dy}c(y)

Thus, d/dy is constant. We can take f(x,y)=xy²-2x². This function f satisfies that  F = ∇f.
