A catapult launches a boulder with an upward velocity of 184 feet per second. The height of
the boulder, (h), in feet after t seconds is given by the function h(t) = -16t^2+184 +20. How
long does it take the boulder to reach its maximum height? What is the boulder's maximum
height? Round to the nearest hundredth, if necessary.
Reaches a maximum height of 11.6 feet after 5.75 seconds.
Reaches a maximum height of 549 feet after 11.5 seconds.
Reaches a maximum height of 549 feet after 5.75 seconds.
Reaches a maximum height of 23.2 feet after 11.6 seconds.

answer: the common difference is -0.10

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
