The bus will have the highest kinetic energy and the bike will have the least kinetic energy because kinetic energy =1/2 mass × velocity squared

In order to answer that, we would have to take the mass of each of them. The higher the mass, means there is higher the kinetic energy. We use the equation:

Ek = 1/2*m*v^2

Since velocity will be the same speed, it will be constant. The mass is what makes the difference with the bus having the maximum and the bike having the minimum kinetic energy.

Find the radius and diameter of circle A, if the endpoints of the radius<br> are (-2, -1) and (6,4).
AleksandrR [38]

Step-by-step explanation:

length \: between \: ( - 2, - 1) \: and \: (6,4) \\  =  \sqrt{(x _{1} - x  _{2} )² + (y _{1}  - y _{2})²  }  \\  =  \sqrt{( -  2 - 6)²+ ( - 1 - 4)²}  \\  =   \sqrt{64 + 25}  \\  =  \sqrt{100}  \\  = 10 \: units \\ radius = 10 \: units \\ diameter = 2 \times radius \\ d = 2 \times 10 \\ d = 20 \: units

Suppose f(x) = x2 and g(x) = 2x − 3. What is the value of g(4) + f(−3)?
MAVERICK [17]

In order to find the value of g(4)+f(-3), we must substitute those values into the functions first.

Substitute -3 into f(x).

f(x)=x²

f(-3)=(-3)²

f(-3)=9

Substitute 4 into g(x).

g(x)=2x-3

g(4)=2(4)-3

Using the rules of PEMDAS, multiply first then subtract.

g(4)=8-3

g(4)=5

Therefore, if f(-3) is 9 and g(4) is 5, we must add the two values together.

5+9=14

<u>The value of g(4)+f(-3) is 14.</u>

Can you help me answer this question
soldier1979 [14.2K]
X=3. So how did it was:
Xsq - 9x - 4 ÷x+2
Xsq-9x-4 ÷x =-2
Xsq-9x ÷ x= - 2-4
Xsq-9x÷x=-6
Xsq-9x=-6x
Xsq=-6x+9x
Xsq=3x
Xsq÷x=3
X=3
