A = v/t. Solve for t

Answers

A = v/t Multiply both sides by t
A(t) = v Divide both sides by A
t = v / A

Simplify a - {5b - [a - (3b - 2c) + c - (a - 2b -c. ]}.
-a - 6b + 4c
a - 6b + 4c
a - 10b + 4c
-a + 10b + 4c

Answers

♥B)a - 6b + 4c

♥First you need to distribute the Negative Sign.

=a+−1(5b−(a−(3b−2c)+c−(a−2b−c)))

=a+−1(5b)+−1(−a)+−1(3b)+−1(−2c)+−1(−c)+−1a+−1(−2b)+−1(−c)

=a+−5b+a+−3b+2c+c+−a+2b+c

♥Now you need to Combine Like Terms:

=a+−5b+a+−3b+2c+c+−a+2b+c

=(a+a+−a)+(−5b+−3b+2b)+(2c+c+c)

=a+−6b+4c

♥and you get your final answer: a−6b+4c

Each exterior angle of a regular polygon is 9°Calculate the number of sides of the polygon

Answers

Answer:

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide this by the value of 1 exterior angle to find the number of sides n

n = 360 ÷ 9 = 40

Answer:

Required Answer:-

Let the number of sides=x

Each angle measures 9°

As we know that in a polygon

${\boxed{\sf Sum\;of\:exterior\:angles=360°}}$

Substitute the values

${:}\longrightarrow$ $\sf 9x=360$

${:}\longrightarrow$ $\sf x={\frac {360}{9}}$

${:}\longrightarrow$ $\sf x=40$

$\therefore$ Number of sides=40.

What are the zeros of j(x) in the polynomial equation?

Answers

Answer: x = $(-3)/(2)$ , 0, $(3)/(2)$

Step-by-step explanation:

To find the zeros, we will find the solutions to this equation that make it equal 0. This is a cubic function, so we can assume that there will be three solutions.

Given:

$\displaystyle J(x) = (12x^3)/(5) -(27x)/(5)$
