Answer:

For me the answer was (f+g)(x)=4x^3+x^2+5x+2

Step-by-step explanation:

A function assigns the values. The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.

A function assigns the value of each element of one set to the other specific element of another set.

Given that f(x)=4x²+5x-3 and g(x)=4x³-3x²+5, therefore, the value of the (f-g)(x) can be written as,

(f-g)(x) = f(x) - g(x)

          = 4x² + 5x - 3 + 4x³ - 3x² + 5

          = 4x³ + 4x² - 3x² + 5x + 5 - 3

          = 4x³ + x² +2

Hence, The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.

Answer:

Carbon-14 will take 19,035 years to decay to 10 percent.

Step-by-step explanation:

Exponential Decay Function

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.

An exponential decay can be described by the following formula:

[tex]N(t)=N_{0}e^{-\lambda t}[/tex]

Where:

No  = The quantity of the substance that will decay.

N(t) = The quantity that still remains and has not yet decayed after a time t

[tex]\lambda[/tex]     = The decay constant.

One important parameter related to radioactive decay is the half-life:

[tex]\displaystyle t_{1/2}=\frac {\ln(2)}{\lambda }[/tex]

If we know the value of the half-life, we can calculate the decay constant:

[tex]\displaystyle \lambda=\frac {\ln(2)}{ t_{1/2}}[/tex]

Carbon-14 has a half-life of 5,730 years, thus:

[tex]\displaystyle \lambda=\frac {\ln(2)}{ 5,730}[/tex]

[tex]\lambda=0.00012097[/tex]

The equation of the remaining quantity of Carbon-14 is:

[tex]N(t)=N_{0}e^{-0.00012097\cdot t}[/tex]

We need to calculate the time required for the original amout to reach 10%, thus N(t)=0.10No

[tex]0.10N_o=N_{0}e^{-0.00012097\cdot t}[/tex]

Simplifying:

[tex]0.10=e^{-0.00012097\cdot t}[/tex]

Taking logarithms:

[tex]ln 0.10=-0.00012097\cdot t[/tex]

Solving for t:

[tex]\displaystyle t=\frac{log 0.10}{-0.00012097}[/tex]

[tex]t\approx 19,035\ years[/tex]

Carbon-14 will take 19,035 years to decay to 10 percent.

this is true :)

Step-by-step explanation:

Yes, a system of two equations in two variables whose graphs are a parabola and a circle can have four real ordered-pair solutions.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.

Given that a system of two equations in two variables whose graphs are a parabola and a circle can have four real ordered-pair solutions.

It is because the there are two systems of equations and two variables in it.

Answer:

D. a║b, because if two lines are perpendicular to the same line, then they are parallel to each other.

Step-by-step explanation:

This is more of a rule than anything else, but to prove this, you can think of c as the transversal. The 4 angles at the intersection of line a and line c are 90 degrees, and so are the 4 angles at the intersection of line b and line c. Using the converses of the Corresponding Angles Theorem, Same Side Interior Angles Theorem, Alternate Interior Angles Theorem, etc.., you can prove that a and b are parallel.

Answer:

x = 7

y = 10

Step-by-step explanation:

<K and <NLK are marked as being equal.

That means that KN and LN are equal.

So LN = 6

y - 4 = 6

y = 4 + 6 = 10

For the same reason LN = LM

That means that x + 3 = 10

x = 10 - 3

x = 7

Answer:

Your answer is -25

Answer:

Less than 25%

Step-by-step explanation:

1. Find the difference of the two numbers: 1,207 - 957 = 250

decrease = original number - new number

2. Then, divide the decrease by the original number

250/1,207 = 0.207

3. Multiply the answer by 100 to get the percentage

0.207 x 100 = 20.7%

Therefore, the number of people fell by 20.7%

Hence, the answer is less than 25%

Answer:

C

Step-by-step explanation:

To find the area of a circle, take its radius (3) and square it. In this case, 3 times 3 = 9. Then, you multiply the answer by pi, which rounds to 3.14, but is more like 3.14159265......etc, etc. There is a rhyme for that: May I have a large container of coffee beans? Where the length of each word is a number of pi. Anyway, most people would write 9pi, but this is asking for the exact answer, so you can do 3.14 times 9, which equals roughly 28.27.

Answer:

the graph is of a cubic function.

Step-by-step explanation:

f(x)= x^3. It should have at least one zero

The graph shows cubic polynomial.

A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are also known as indeterminates.

Given:

In the graph the number of times the graph touches the x- axis it will have that many zeroes or solution for the polynomial.

The given graph touches the x-axis three times which shows the polynomial will have three solution and the degree of the polynomial is 3.

Hence, the graph shows cubic polynomial.
