Answer: D. $102\ m^2$

Step-by-step explanation:

Given : The surface area of a triangular pyramid is $408 m^2$ .

We know that the total number faces in a triangular pyramid =4

If all the faces of the pyramid are congruent, then the area of one face of this pyramid will be :_

$408\div 4=102\ m^2$

Hence, the area of one face of this pyramid = $102\ m^2$

What is the remainder when 6x^4-3x^5+2x^3+x-3 is divided by x+1

Svetlanka [38]

The remainder is 3 when we need to divide $6x^4-3x^5+2x^3+x-3\,\,by \,\,x+1$

Step-by-step explanation:

We need to divide $6x^4-3x^5+2x^3+x-3\,\,by \,\,x+1$ and find the remainder

Dividing:

The division is shown in figure below:

The quotient is: $-3x^4+9x^3-7x^2+7x-6$

The remainder is: 3

So, The remainder is 3 when we need to divide $6x^4-3x^5+2x^3+x-3\,\,by \,\,x+1$

Question 8 of 10 What is sin 30º? 60 2 901 D A B. c.. () E. E )

levacccp [35]

Answer:

A. $\displaystyle \frac{1}{2}$

General Formulas and Concepts:

Trigonometry

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

sin 30°

Step 2: Solve

Since sin is opposite over hypotenuse, we need to find the length of the opposite leg of the angle and the length of the hypotenuse.

Given the triangle and it's values, the opposite leg to the 30° angle is 1 and the hypotenuse is 2.

Substituting it into sin, we have:

sin 30° = 1/2 = 0.5

∴ our answer is A.
