Answer:
- The scientist can use these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.
- The scientist can substitute these measurements into 
and solve for the distance between the Sun and the shooting star (which would be the hypotenuse of the righ triangle).
Step-by-step explanation:
You can observe in the figure attached that "AC" is the distance between the Sun and the shooting star.
Knowing the distance between the Earth and the Sun "y" and the angle x°, the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.
This is:
In this case:
Therefore, the scientist can substitute these measurements into , and solve for the distance between the Sun and the shooting star "AC":
Answer:
The answer is 2.4 Miles per hour
Step-by-step explanation:
15.12 divided by 6.3= 2.4 MPH
So percent means parts out of 100
so 12%=12/100=1.2/10=0.12/1=0.12
3.84 is 12% of what
'of' means multiply
'is' means = sign
therefor
3.84=0.12 times what
divide both sides by 0.12
32=what
th enumber is 32
Hello!
The mean is the average of the numbers
To find the average you add them all up and divide the sum by the amount of numbers added
87 + 72 + 99 + 93 + 84 = 435
Divide the sum by the amount of numbers added
435 / 5 = 87
The answer is 87

Use the FOIL method
First, Outside, Inside, Last
(2x -5)(x + 3)
2x(x) = 2x²
2x(3) = 6x
-5(x) = -5x
-5(3) = -15
2x² + 6x - 5x - 15
simplify
2x² + 6x - 5x - 15
2x² + x - 15
2x² + x - 15 is your answer
hope this helps
