The work is done on the toy car is 164.4 J .

<h3>How to calculate work done?</h3>

We are aware that the definition of work is the multiplication of the magnitude of the displacement (d) and the component of the force acting in the displacement direction.

When an object moves over a distance while being applied with force, the work is considered to have been completed.

Three categories can be used to classify the type of labor performed. Positive work, negative work, and zero work are the three types. The angle between force and displacement determines the kind of work that is done. Positive work is defined as any work that causes an object to move in the direction of the applied force.

Given ,

Work = force * distance

Force = 5.2 N

Distance = 32 m

So ,

Work = 5.2 * 32

= 166. 4 J

Therefore the work is done is 164.4 J

Answer: The chances of landing on blue are 1 in 4, or one fourth. The chances of landing on red are 1 in 4, or one fourth.

Step-by-step explanation:

Reduce 1/4 to lowest terms14 is already in the simplest form. It can be written as 0.25 in decimal form (rounded to 6 decimal places). Steps to simplifying fractions find the GCD (or HCF) of numerator and denominator GCD of 1 and 4 is 1 divide both the numerator and denominator by the GCD1 ÷ 14 ÷ 1 reduced fraction: 14Therefore, 1/4 simplified to lowest terms is 1/4.

Consider the quadratic function f(x)= 9x^2+30x+25=0
Alchen [17]

Answer:

D) 0

There is 1 real solution.

Step-by-step explanation:

Hi there!

f(x)= 9x^2+30x+25=0

This is written in standard form:

f(x)=ax^2+bx+c

This means:

a=9

b=30

c=25

The discriminant states:

D=b^2-4ac

If D>0, there are 2 real solutions.

If D=0, there is 1 real solution.

If D<0, there are 2 complex solutions.

Plug in the values:

D=30^2-4(9)(25)\\D=0

Therefore, there is 1 real solution.

I hope this helps!

How do you solve this problem 3x+2 (x+4)=x-(x+2)
Sidana [21]
Expand the left and the right side .
3x + 2x + 8 = x - x - 2
then you simplify
5x + 8 =  - 2
then continue ...
you will get x = -2
