C. y=7

Step-by-step explanation:

guy above me was right

The horizontal asymptote of the given function  [tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex]  would be y = 7.

The line y = a is a horizontal asymptote if the function f(x) tends to 'a' from the upside of that line y = a, or from downside of that line.

The given function is

[tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex]

We need to determine the horizontal asymptote.

Horizontal asymptote;

From the given function, it is obvious that the denominator's degree is smaller than the numerator's degree.

Then, the horizontal asymptote is the y-axis.

Thus, the horizontal asymptote is y = 7.

Answer:

80

Step-by-step explanation:

This is calculated as:

(Number of ducks with bands × Number of examined ducks)/ Number of ducks found with leg band

= Number of ducks with bands = 12 ducks

Number of examined ducks = 20 ducks

Number of ducks found with leg band = 3 ducks

Hence:

12 × 20/3

= 240/3

= 80 ducks

Therefore, 80 ducks used the ponds

Answer:

an electron moving into the nucleus

When an electron moved to an excited state, it will produce light. So, the correct option is (D).

Light are commonly referred as Electromagnetic Radiation which can be detected by the human eye. This spectrum is extremely broad which ranges from low energy radio waves with wavelengths that are to high energy gamma rays with wavelengths which are less than 1x [tex]10^-^1^1[/tex].

The largest electromagnetic waves having wavelengths from a few centimeters to over 100 meters called as radio waves while the smallest electromagnetic waves having wavelengths which is the size of an atomic nucleus are called gamma rays. In between these waves, microwaves, infrared light, visible light, ultraviolet light and X-rays. It refers to visible radiant energy.

Light is emitted when an electron jumps from a higher orbit to a lower orbit and absorbed when it jumps from a lower to higher orbit which causes to produce light.

Thus, when an electron moved to an excited state, it will produce light. So, the correct option is (D).

Answer:

[81 is the missing number.]

Step-by-step explanation:

7+x=88

Let us substitute the mixing number as x.

To find a variable we must ISOLATE it.

To isolate in this situation, we must remove the 7.

We must subtract 7 from both sides, to isolate x. like this-

7-7+x=88-7

This results in,

x=81

So this missing number or (x) is equal to 81

Answer:

She has 140 coins in total.

Step-by-step explanation:

Since 7 coins is only 5% of the entire collection, 7 coins=5%. 100% is the total. So first you need to divide 100 by 5 which is 20 (100÷5=20). Next, you need to multiply 20 by 7 (20×7=140) to find out how much coins she has in total.

Answer:

$467.37

Step-by-step explanation:

Given data

Principal= $300

Rate= 3%

Time = 15 years

Applying the compound interest formula, we have

A=P(1+r)^t

A=300(1+0.03)^15

A=300(1.03)^15

A=300*1.5579

A=$467.37

Hence after 15years the balance will be $467.37
