Answer:
50 meters
Step-by-step explanation:
The area of a circle is 
, so assuming that 
is 3.14, we can make the equation 
.
Assuming the radius is r, which is 4, we can substitute the values into the equation.
This question is asking for the area to the nearest square meter so rounding 50.24 to the nearest square meter results in 50.
Hope this helped!
Answer:
24
Step-by-step explanation:
(60 × 2 ) ÷ 5 = 24.
60 because hour is 60 minutes
× 2 because she says it for 2 hours
÷ 5 because she says it every 5 minutes
Answer:
14.6 minutes
Step-by-step explanation:
Since there is a 1 ms increase per day and there are 365 days a year, the time increase per year is 1 ms/day × 365 days/year = 365 ms/year.
So, in 24 centuries, there are 24 × 1 century = 24 × 100 years = 2400 years (since 1 century = 100 years)
So, the total of the daily increase in time in 24 centuries is time increase per year × 24 centuries
= 365 ms/year × 2400 years
= 876000 ms
= 876 s
= 876 s/60s
= 14.6 minutes
A graph of the equation shows the appropriate choice to be
C. 2_____
If you would rather, you can look at the value of the discriminant. For the equation y = ax²+bx+c, the discriminant (d) is
d = b²-4ac
For your equation, this evaluates to
d = (-8)²-4(2)(5) = 64 -40 =
24When the discriminant is
positive, the function has
two real roots (2 x-intercepts). When it is zero, there is only one x-intercept, and when it is negative, there are none (the roots are complex).
