The table below shows the height,
h
, in meters, of an object that is thrown off the top of a building as a function of
t
, the time in seconds after it is thrown.

t
0.5 1 1.5 2 2.5 3
h
(
t
)
88.725 98 104.825 109.2 111.125 110.6

Using your calculator to do a quadratic regression, express the height of the object as a function of the number of seconds that have passed since the object was thrown.

Round all numbers to 1 decimal place.

Using your quadratic regression, how high will the object be 2.8 seconds after it is thrown?

Round to 3 decimal places.

Using your quadratic regression, how long will it take the object to reach 31 meters?

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

not sure but it may be b, as i said i'm not sure.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
