Answer:
The side opposite the right angle is the hypotenuse. The Pythagorean theorem is used to solve for the length of the hypotenuse. If a right triangle has legs measuring a and b with hypotenuse c, the Pythagorean theorem is a² + b² = c². Solving for c is as simple as taking the square root of both sides of the equation.
Answer:
x^2 -81
Step-by-step explanation:
(x+9)(x-9)
FOIL
first x*x = x^2
outer -9x
inner 9x
last -9*9 = -81
Add them together
x^2 -9x+9x -81
Combine like terms
x^2 -81
Answer:
C
Step-by-step explanation:
The Y-axis is the up and down part so if the Triangle was flipped on the Y-axis then it would be facing down and the diagrams would match
Answer:
Step-by-step explanation:
False f(x) is not a function as there are multiple solutions for f(6.5)
True f(4) = 225
True f(a) = 50 has no solution as we are given no information as to what "a" is.
Even f(x) = 50 has no solution in the domain provided
False f(1) = 250
False f(100) is beyond the domain of the plot. Even if the plot repeats, it never gets down to 6.5...and how does one end up with a half a can, anyway?
False The plot never intersects the x axis
True F(0) = 250
True Seems to me the graph is a tell-all...not being discrete at all
(Joke) :)
Actually the graph lines are not correct. The data is number of cans, plotted against time. While time is continuous, cans must be sold in units. The plot points are valid, but the lines between them are just wishful thinking. If we ignore the lines, the plot is discrete.
True There are 300 cans in the machine at 1:30 pm
False 0 ≤ t ≤ 12 hrs is the domain
True f(10) = f(12) and all points between them have a value of 250
True graph slopes from f(2) to f(6.5) have negative values.
Answer:
4
Step-by-step explanation:
The absolute value is the distance between a number and zero. The distance between -4 and 0 is 4.
