Answer:

Rational, integers, whole, natural, real

Step-by-step explanation:

109 is rational because it can be expressed as the ratio of two integers: 109:1

109 is integer because it can be written with no fractions

109 is a whole number because it has no decimals

109 is natural because it is an integer greater than 0

Hope this helps! ;)

A Ferris Wheel is built such that the height in feet above ground of a seat on the wheel at time t seconds can be modeled by h(t

MAVERICK [17]

Answer:

at time, t = 8 seconds and t = 24 seconds Ferris Wheel be 53 feet above the ground

Step-by-step explanation:

Data provided in the question:

height in feet above ground of a seat on the wheel at time t seconds is

modeled as

h(t) = $53 + 50\sin((\frac{\pi t}{16} - \frac{\pi}{2})$

now,

at height 53 above the ground, we get the equation as:

53 = $53 + 50\sin(\frac{\pi t}{16} - \frac{\pi}{2})$

or

$50\sin(\frac{\pi t}{16} - \frac{\pi}{2})$ = 53 - 53

or

$\sin(\frac{\pi t}{16} - \frac{\pi}{2})$ = 0

also,

sin(0) = 0

and,

sin(π) = 0

therefore,

$(\frac{\pi t}{16} - \frac{\pi}{2})$ = 0

or

$\frac{\pi t}{16} = \frac{\pi}{2}$

or

t = 8 seconds

and,

$(\frac{\pi t}{16} - \frac{\pi}{2})$ = π

or

$\frac{\pi t}{16}= \pi + \frac{\pi}{2}$

or

$\frac{\pi t}{16}= \frac{3\pi}{2}$

or

t = 24 seconds

Hence,

the at time, t = 8 seconds and t = 24 seconds Ferris Wheel be 53 feet above the ground

How do you determine the value of isosceles triangles?

amid [387]

There's really no such thing as the value of a triangle.

Every triangle has three sides, three angles, a base, a height, and an area,
and there could be problems that ask us to find any one of those.

Whatever we need to find, the process is always the same:

-- Take the information that's given.

-- Gather up everything you can remember that talks about a relationship
between what you're given and what you need to find.

-- Use them together to find the missing value.
