What are the domain and range of this function?

Mathematics
1 answer:
Arlecino [84]4 years ago
8 0

Answer:

Correct answer:  The third answer is correct

Step-by-step explanation:

The domain of each function is defined by observing the behavior of the function from left to right by following the growth of numbers on the x axis of real numbers.

In the same way, the range of each function is defined by observing the behavior of the function from the bottom y axis upwards by following the growth of numbers on the y axis of real numbers.

The given function extends from negative infinite to positive infinite on the x axis and that is the domain of this function.

The minimum of a given function is 4, which means that the function exists from 4  upwards and that is the range of the function.

Domain; all real numbers or x ∈ ( -∞ , + ∞)

Range:  ( y ≥ 4 )

allsm [11]

Answer:

Are needed 863.5\ in^{2} of blue tile

Step-by-step explanation:

we know that

To find how much blue tile do you need, subtract the area of the smaller circle from the area of the large circle

step 1

<em>Find the radius of the large circle</em>

The circumference of the circle is equal to

C=2\pi r

we have

C=113.097\ in

substitute and solve for r

113.097=2\pi r

r=113.097/(2\pi)

assume

\pi=3.14

r=113.097/(2(3.14))=18\ in

step 2

Find the area of the large circle

A=\pi r^{2}

we have

r=18\ in

substitute

A=\pi (18)^{2}=324\pi\ in^{2}

step 3

Find the area of the smaller circle

A=\pi r^{2}

we have

r=7\ in

substitute

A=\pi (7)^{2}=49\pi\ in^{2}

step 4

Find the difference of the areas

324\pi\ in^{2}-49\pi\ in^{2}=275\pi\ in^{2}

assume

\pi=3.14

275(3.14)=863.5\ in^{2}

Please help!! Local wildlife experts have begun to track the population of trout in their area. The function f represents the ap
jeka57 [31]

Answer:

Option C.

Step-by-step explanation:

We know that

f(t) = 1.5t + 50

represents the approximate population of trout in Sky Lake

And

g(t) = 0.1t^2 - 4t + 70

represents the approximate population of trout in Lake Cyan

The total trout population in the area is described as

f(t) + g(t)

f(t) + g(t) =  [1.5t + 50] + [0.1t^2 - 4t + 70]

f(t) + g(t) =  [1.5t + 50+ 0.1t^2 - 4t + 70]

f(t) + g(t) =  [0.1t^2 -2.5t + 120]

f(t) + g(t) =  0.1t^2 -2.5t + 120

Option C.
