Eric is at the top of a cliff that is 500ft from the oceans surface. He is waiting for his friend to climb up and meet him. As he is waiting, he decides to start casually tossing pebbles of the side of the cliff. The pebbles have an upward velocity of 5 feet/second. A. write the equation to model the pebble Eric throw off the cliff.

B. How long does it take the pebble to hit the water?

C. If four seconds hve gone by, what is the height of the pebble from the ocean?

D. What is the highest point the pebble will go?

E. Suppose that cliff was 600ft high, what would the equation be?

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
