Answer:

In mathematics, a cube root of a number x is a number y such that y³ = x. All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. In mathematics, an nth root of a number x is a number r which, when raised to the power n, yields x: {\displaystyle r^{n}=x, } where n is a positive integer, sometimes called the degree of the root. A root of degree 2 is called a square root and a root of degree 3, a cube root.

A plane slices diagonally through a rectangular prism as shown. Which term best describes the cross-section formed by the inters
joja [24]

Answer:

Rectangle shaped cross section is formed by intersection of plane and prism.

Step-by-step explanation:

Given: A rectangular Prism.

To find: Shape of Cross Section when a plane intersect the prism diagonally

A plane intersect the Rectangular prism .i.e, Cuboid diagonally which means plane passes from top edge of cuboid to edge on bottom on opposite side.

Figure is attached.

In this way we get a Rectangular shaped Cross section which includes edges of cuboid and diagonals of the side faces.

Therefore, Rectangle shaped cross section is formed by intersection of plane and prism.

What is the total repayment made, including principal and interest, on a loan of $1,100 at 3.5% interest compounded annually ove
olchik [2.2K]

The total repayment made, including principal and interest is $1262.27

<h3>Compound interest</h3>

The formula for calculating the compound interest is calculated as shown below;

A = P(1+r)^t

where

P is the principal = $1100

rate = 3.5% = 0.035

time "t" =4 years

Substitute

A. = 1100(1+0.035)^4
A = 1100(1.035)^4
A = 1100(1.14752)

A = 1262.27

Hence the total repayment made, including principal and interest is $1262.27

4(x-6)+6=6x-9 what is x
Gala2k [10]

Answer:

− 9/2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x−6)+6=6x−9

Step 1: Simplify both sides of the equation.

4(x−6)+6=6x−9

(4)(x)+(4)(−6)+6=6x+−9(Distribute)

4x+−24+6=6x+−9

(4x)+(−24+6)=6x−9(Combine Like Terms)

4x+−18=6x−9

4x−18=6x−9

Step 2: Subtract 6x from both sides.

4x−18−6x=6x−9−6x

−2x−18=−9

Step 3: Add 18 to both sides.

−2x−18+18=−9+18

−2x=9

Step 4: Divide both sides by -2.

−2x/−2=9/−2

x=−9/2
