Answer:
x ∈ {-3, 1.2, 1.25}
Step-by-step explanation:
"Solve" is non-specific as to the solution required. We assume you want the x-intercepts.
A graph shows the zeros to be ...
The equation can be factored as ...
y = (1/2)(x +3)(4x -5)(5x -6)
Answer:
The ratio between them is approximately
, therefore the correct answer is A.
Step-by-step explanation:
In order to calculate the ratio of the diameter of the Sun to the diameter of the Earth we will first represent the Earth's diameter as a scientific notation, to do this we will add one to the power of ten for every time the comma walks to the left until there's only one number to the left. This is done to make the division easier,

The ratio is given by the Sun's diameter divided by the Earth's, as shown below:

The ratio between them is approximately
, therefore the correct answer is A.
The concept that can be used in order to answer this item is that of ratio and proportion. The ratio of the man's height and the length of his shadow should be proportional or equal to the ratio of the tower height and length of its shadow. If we let x be the height of the tower, the equation that would help us solve this item is,
2 / x = 0.5 / 13.5
The value of x is equal to 54. Thus, the tower's height is approximately 54 meters.
