The formula F = ma shows the relationship between force, mass, and acceleration. Solve this formula for a.

Answers

Answer 1

Answer:

Answer:

Solution is $a=(F)/(m)$

Step-by-step explanation:

We have Force, F = Mass x Acceleration.

That is F = m x a

Dividing both sides by $(1)/(m)$

We will get

$(1)/(m)* F=(1)/(m)* m* a\n\n(F)/(m)=(m* a)/(m)\n\n(F)/(m)=(m)/(m)* a\n\na=(F)/(m)$

Solution is $a=(F)/(m)$

Answer 2

Answer: The formula you would use to find acceleration would be A= f/m

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 solutions of 3x^2 + 14x + 16 = 0?x = -8/3, –2

x = –2, -3/8

x = 3/8, 2

x = 8/3, 2

Answers

Answer:

The correct option is A) x = -8/3, –2.

Step-by-step explanation:

Consider the provided equation $3x^2 + 14x + 16 = 0$

The above equation is in the form of $ax^2 +bx + c = 0$

The quadratic formula to find the root of the equation is:

$x={\frac {-b\pm {\sqrt {b^(2)-4ac}}}{2a}}\ \$

By comparing the above equation with the general equation we can conclude that:

a = 3, b = 14, and c = 16

Substitute the respective values in the above formula:

$x={\frac {-14\pm {\sqrt {14^(2)-4(3)(16)}}}{2(3)}}\ \$

$x={\frac {-14\pm {\sqrt {196-192}}}{6}}\ \$

$x={\frac {-14\pm {\sqrt {4}}}{6}}\ \$

$x={\frac {-14\pm2}{6}}\ \$

$x={\frac {-14+2}{6}}\ \ } or\ {\displaystyle x={\frac {-14-2}{6}}\ \$

$x={\frac {-12}{6}}\ \ } or\ {\displaystyle x={\frac {-16}{6}}\ \$

$x=-2}\ \ } or\ {\displaystyle x={\frac {-8}{3}}\ \$

Hence the solutions of the provided equation is $x=-2}\ \ } or\ {\displaystyle x={\frac {-8}{3}}\ \$ .

Thus, the correct option is A) x = -8/3, –2.

the solution is :
x= -8/3 , -2

What is 1/5 reduce to its lowest term

Answers

1/5 is the lowest term because the numerator has 1

1/5 reduced is just 1/5 because if anything has a 1 in it's numerator you know that the GCF is just 1 so you can't have a even more simplified form of this.

What is true concerning the lines graphed by the system of equations shown below 8x+6=2y 12x-3=3y

Answers

Answer: the lines are parallel to each other

Step-by-step explanation:

First, what we can do is solve both equations for y, putting them in slope-intercept form, y = mx + b:

2y = 8x + 6 3y = 12x - 3
/ 2 / 2 / 3 / 3
y = 8x/2 + 6/2 y = 12x/3 - 3/3
y = 4x + 3 y = 4x - 1

For both equations, m = 4, or they have the same slope of 4. Lines that have the same slope are parallel to each other.

I hope this helps! :)

In order to clear out room for new merchandise, James decided to mark down some of the items for sale in his electronics store. He marked down DVD players by 36%, and he marked down stereo tuners by 22%. If DVD players cost $41.60 after the markdown and stereo tuners cost $69.42 after the markdown, which item’s price was reduced by more, and by how many dollars more was it reduced? Round all dollar values to the nearest cent.

Answers

Answer:

a) Which item’s price was reduced by more, and by how many dollars more was it reduced?

The DVD player's price was reduced more by $3.82 than the stereo tuner's price.

b) Round all dollar values to the nearest cent.

Rounding $3.82 dollars to the nearest cents

$1 = 100 cents

$3.82 =

3.82 × 100 cents

= 382 cents

The DVD player's price was reduced by 382 cents more than the stereo tuner's price

Step-by-step explanation:

Lets day the original price of the DVD player was $100

We are told the price was marked down to 36%

36% of $100 = $36

$100 - $36 = $64

We are told the DVD cost $41.60 after the markdown.

Original cost of DVD =

$41.60/$64 × 100 = $65

Lets the original price of the Stereo player was $100

We are told the price was marked down to 22%

22% of $100 = $22

$100 - $22 = $78

We are told the DVD cost $69.42 after the markdown.

Original cost of Stereo =

$69.42/$78 × 100 = $89

DVD = $65 - $41.60 = $23.40 less

Stereo = $89 - 69.42 = $19.58 less

Difference between the DVD and the Stereo is

$23.40 - $19.58 = $3.82

Therefore,the DVD player's price was reduced by $3.82 more than the stereo tuner's price

Rounding $3.82 dollars to the nearest cents

$1 = 100 cents

$3.82 =

3.82 × 100 cents

= 382 cents
