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 )

You are re-tiling the entry to your home and want to create a fancy circular medallion in the center. You want to create a large

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

$\pi=3.14$

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

algol [13]

Answer:

$93.75

Step-by-step explanation:

1: calculate 25% of $125

0.25 * 125 = $31.25 this is the money that is saved.

2: subtract

$125 - $31.25 = $93.75 this is the sale price

Answer:

a- about 3$

b-about 8$

c-about .04

Step-by-step explanation:

a-100.8/35=2.88

2.88 is around 3

b-49.2/6=8.2

8.2 is close to 8

c-.78/20=.039

.039 is the nearest to .04

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.
