Answer:
Step-by-step explanation:
we know that
In this problem
The value of x represent the radius of the circle
so
Applying the Pythagoras theorem in the right triangle of the figure, you can find the radius of the circle O
see the attached figure to better understand the problem
square root both sides
Answer:
Step-by-step explanation:
What is the question? So far you have ran 28 miles in 4 hours.
Answer:
+3
Step-by-step explanation:
(-m)^(-3) = -m^3, since (-1)^-3 = 1 / (-1).
If m = 2 then we have -2^(-3), or -1 / [2^3]), or -1/8.
Finally, if n = -24, the original expression becomes
(-1/8)(-24) = +3
Second problem: Only the first expression simplifies to a negative result.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
isolate the variable y
Adds 10 both sides
Divide by 2 both sides
The solution of the inequality is the shaded area below the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is (0,5) (value of y when the value of x is equal to zero)
The x-intercept of the dashed line is (-3.33,0) (value of x when the value of y is equal to zero)
