13: Since f(1)=10, the sequence must start with 10. We have only one sequence starting with 10, and indeed it verifies f(n+1)=f(n)-2, i.e. the next term is 2 less than the previous one.
14: If y varies directly with x, then there is a constant of variation k such that
In your case, F varies directly with m, with a constant of variation of 32.2, so we have
Quadrilateral are four sided shapes. e.g
There are 2 sides in a quadrilateral and each of them are 180° shown above. Angles in a quadrilateral add up to 360°.
For example: The example is shown in the picture above.
Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
