The correct answer should be C to this question
The weight (or mass) is irrelevant.
The period t = sqrt(2*pi*sqrt(l/g) where g is the acceleration due to gravity.
so t = 2*pi*sqrt(5/9.8) = 4.49 seconds.
Frequency = 1/period = 0.223 Hertz.
Answer:
I think it is question 2, B
Answer:
Markdown is a reduction in the price of a product, made either by a commercial promotion, by a limited-time offer, by a discount due to a failure in the product, or any other situation that implies the realization of said reduction in the final price of the product for sale.
Thus, if the original price of the product is $282, and it has a markdown of 10%, to determine the discounted amount and the final price of the product, the following calculation must be made:
282 x 0.10 = X
28.2 = X
Thus, the discount on the original price is $ 28.20. Therefore, the final sale price will be $ 253.80 (since 282 - 28.20 is equal to that number).
The answer is - 40. Observe.
y/-4 + 5 = 15
y = -40
-40/-4 = 10
10 + 5 = 15
Thus, y= -40
