Answer:
C What was the temperature on December 10?
Step-by-step explanation:
Because it uses numbers and statistical questions have to deal with numbers.
Use the cos ratio to figure this out. You have the length of the hypotenuse and the length of the leg on the ground. The hypotenuse is 20 and the leg is 10. The cos ratio says that cosA = side adjacent/hypotenuse. So fill in the blanks here: cosA = 10/20...cosA=1/2. In your calculator, you will enter inverse cos(.5) to find that the angle in question is 60 degrees. To find the inverse function on your calculator, press the "2nd" button and the "cos" then in the (), enter ".5".
Answer:
1) 1 2)100 3)6.25.
Step-by-step explanation:
Any trinomial is of the form ax^2+bx+c .
To make the expression a perfect square we take half of b term then square it Add 
This is what we add to make the expression a perfect square.
1)Half of coefficient of x term is 1 .
Square it that is 1 is added to make it a perfect square.
2) Half of coefficient of x term that is 20÷2=10 .Square it that is 100 is added to make it a perfect square.
3) Half of coefficient of x that is 5÷2=2.5.Square it 6.25 is added to the expression to make it a perfect sqauare.
