7 0

Answer:

  84x^10

Step-by-step explanation:

The coefficients multiply, and the exponents add.

  (4x)( -3x^6)(-7x^3) = (4)(-3)(-7)x^(1+6+3) = 84x^10

__

The rule for exponents is ...

  (x^a)(x^b) = x^(a+b)

The crosssectional areas of triangular prism and a night cylinder are congruent. The triangular prism has a helght of 5 units, a
dmitriy555 [2]

Answer:

The volume of the triangular prism  is not equal to the volume of the cylinder

Step-by-step explanation:

Given that:

The cross sectional area of triangular prism and a night cylinder are congruent. The term 'congruent' means when two objects or shapes are placed above each other , they should both overlap exactly.

It was given that:

The triangular prism has a height of 5 units

and the right cylinder height of 3 units

The conclusion that can be drawn from this is that:

The volume of the triangular prism  is not equal to the volume of the cylinder.

This is because, they do not occur in the same family. A triangular prism is a three - dimensional shape that has identical, parallel ends and parallel faces.

A triangular prism has two triangles at it ends and three rectangular faces.

The volume of the triangular prism is calculate by using the formula:

V= \dfrac{1}{2}\times b \times h\times l

On the other hand, a cylinder is a shape with two circular ends and a curved surface.The two circular ends are congruent and both circular end posses the same cross section from one end to the other in the cylinder.

The volume of a cylinder is calculated by using the formula:

V = πr²h

Thus, we conclude that irrespective of the nature of their congruency, since the heights are different which will definitely affects their volume, the the volume of the triangular prism is not equal to the volume of the cylinder.

Write the sum or difference in the standard form a + bi.
REY [17]

Answer:

Sum = 13+ 4i            Difference = -5 - 8i

Step-by-step explanation:

Given complex number as (4 -2i)  and  (9 + 6i)

Sum of these complex number is

(4 -2i)  + (9 + 6i) = ( 4 +9) + (6i -2i)

                           = 13 +4i

Difference of these complex number is

(4 -2i)  - (9 + 6i) = (4 -9) - (2i +6i)

                        = -5 - 8i

Hence the sum and Difference of given complex numbers are

Sum = 13+ 4i            Difference = -5 - 8i              Answer

How many different committees can be formed from 12 teachers Abs 43 students of the committee consists of 4 teachers and 3 stude
Marina86 [1]

Answer:

6108795

Step-by-step explanation:

To obtain the number of ways the committee can be selected :

4 teachers from the 12 teachers available and 3 students from the 43 students available

Using combinatorics :

12C4 * 43C3

recall :

nCr = n! ÷ (n - r)!r!

Using calculator :

12C4 = 495

43C3 = 12341

12C4 * 43C3

495 * 12341

= 6108795
