The function h(t) = -4.9t2 + h0 gives the height (h), in meters, of an object t seconds after it falls from an initial height (h0). the table shows data for a pebble that fell from a cliff. time height 1 55.1 2 40.4 3 15.9 to the nearest tenth of a second, how long after the pebble falls will it hit the ground?

Equation: h(t)=- 4.9(t)^2 + 60

Seconds: 3.5

Step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
