A. 8.005 • 10² = 800.5 (Incorrect)
B. 8.500 • 10⁻³ = 0.0085 (Incorrect)
C. 8.005 • 10⁻⁴ = 0.000801 (Incorrect)
D. 8.005 • 10⁻³ = 0.008005 (Correct)
Answer: D. 8.005 • 10⁻³
the mode (rounded to the nearest tenth if needed) of the following data set is 30,29,40,51,39,33,24,60,40,35,58
scoray [572]
The mode is the number that occurs the most in the sequence of numbers, so the mode is 40 since that number is repeated the most in the sequence, 2 times.
Answer:
x=5
Step-by-step explanation:
Since this is a right triangle, we can use the pythagorean theorem
a^2 + b^2 = c^2
x^2+ ( 2x+2)^2 = (2x+3)^2
FOIL the squared terms
x^2 +(4x^2 + 4x+4x+4) = 4x^2 + 6x+6x +9
Combine like terms
5x^2+8x +4 = 4x^2 +12x +9
Subtract 4x^2 +12x +9 from each side
5x^2+8x +4 -4x^2 -12x -9= 4x^2 +12x +9-4x^2 -12x -9
x^2 -4x -5 =0
Factor
(x-5) (x+1) = 0
Using the zero product property
x=5 x=-1
But x cannot be negative or we would have negative length
x=5
Answer:
|x| - 17 = 0
Step-by-step explanation:
That technique for solving equations is: Whatever you do to one side of the equation, you have to do to the other side to preserve the equality The technique for solving inequalities is: Whatever you do to one side of the inequality, you have to do to the other side to preserve the inequality. the techniques are the same. The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses. !!!!!
