The second car will overtake the first car at about 3 hours and 11 minutes.
50*4.19 hours(it's ahead by one hour)=209.5
66*3.19 hours=210.54
So about that much time.
I hope I helped out!
3log2(2x)=3
log(2(2x))^3=log1000
8(8x^3)=1000
x=2.5
Answer:
6,666.67cube units
Step-by-step explanation:
Volume of the square based pyramid = BH/3
B is the base area
H is the height of the pyramid
Base area = Length * length
B = 25 * 25
B = 625 square units
Height = 32units
Volume = 625*32/3
Volume = 6,666.67cube units
Answer: + =
Step-by-step explanation:
The standard form of equation of a circle is written in the form:
+ =
where a and b are the coordinates of the center and r is the radius.
All we need to do is to covert the given equation into this form, how do we do that?
We will achieve this by using the completing method of solving quadratic equation.
Firstly re - write the equation , that is
- 6x + -4y = 12
The next thing is to Complete the square for each of x and y
How do we do this ?
i. multiply the coefficient of x and y by 1/2
ii. square the results
iii. Add the result to both sides of the equation , that is
- 6x + - 4y + = 12 ++
The next thing is to write the Left hand side of the equation as a perfect square binomial and simplify the Right hand side. That is
+ = 25 , that is
+ =
Which is now in standard form of the equation of a circle.
