Answer:

Step-by-step explanation:

A triangular prism is a prism that has two triangular faces and three rectangular sides.

The area of the rectangular sides is A = lbh

A = area, l = length, and h = height.

The area of the triangular faces is A = 1/2bh

A = area, b = base, and h = height.

EastWind [94]
From what I can pick up from your problem statement, you want to know "<span>a similar charm has a diameter of 4 cm what is the circumference."  Please, would you use proper punctuation in your writing, for greater clarity:

"A</span><span> similar charm has a diameter of 4 cm.  What is the circumference?"

The formula for the circumference of a circle, when the diameter is known, is 

C=</span>\pid               or  C=pi*d

In this case, with diamter 4 cm, the circumference, C, is 4pi cm.

Solve the congruence 169x 25 (mod 330)
DIA [1.3K]

First solve the congruence 13y\equiv1\pmod{330}. Euclid's algorithm shows

330 = 25 * 13 + 5

13 = 2 * 5 + 3

5 = 1 * 3 + 2

3 = 1 * 2 + 1

=> 1 = 127 * 13 - 5 * 330

=> 127 * 13 = 1 mod 330

so that y=127 is the inverse of 13 modulo 330. Then in the original congruence, multiplying both sides by 127 twice gives

127^2\cdot13^2x\equiv127^2\cdot5^2\pmod{330}\implies x\equiv127^2\cdot5^2\equiv403,225\equiv295\pmod{330}

Then any integer of the form x=295+330n is a solution to the congruence, where n is any integer.

Please help with problem !!!
True [87]

Answer:

Step-by-step explanation:

y = 2x^2 - 12x +19                Put brackets around the  1st 2 terms. Take 2

y = 2(x^2 - 6x ) + 19             Take 1/2 of the 6 square it and add inside the brackets

y = 2(x^2 - 6 + (6/2)^2) +19 Subtract 2 *9 from the 19. Express 1st 3 terms as ( )^2

y = 2(x- 3)^2 + 19 - 18

y = 2(x - 3)^2 + 1

Answers

vertex: (3,1)
