Answer:

the third graph

The correct graph is Graph 3.

We are given a modulus function f(x) by:

       [tex]f(x)=2|x|[/tex]

We will go through the following graphs by checking the value of the graph at some value of x and see whether the value on the graph at that x matches the value of f(x) at that particular x.

when x=1 we have:

[tex]f(x)=2\times |1|\\\\f(x)=2[/tex]

Graph 1:

When x=1

we have:

[tex]f(x)=0.5\neq 2[/tex]

Hence, Graph 1 does not represent the given function.

Graph 2:

when x=1 we have:

[tex]f(x)=1\neq 2[/tex]

Hence, Graph 2 is not the answer.

Graph 4:

when x=1 we have:

[tex]f(x)<2[/tex]

Hence, graph 4 is not the correct graph to represent f(x).

Hence, we are left with Graph 3.

When we plot the function f(x) we see that it matches the graph 3.

Answer:

212.5

Step-by-step explanation:

10=85

212.5=25

Gavin can drive 8.5 miles with 1 gallon of gas. Therefore, he can drive 212.5 miles with 25 gallons of gas.

The question asks how many miles Gavin can drive on 25 gallons of gas, given that he has driven 85 miles on 10 gallons of gas. This requires the use of proportions to calculate. First, you find out how many miles Gavin can drive on 1 gallon of gas, which is 85 miles / 10 gallons = 8.5 miles/gallon. Then, using this value, we can multiply it by 25 gallons to get the total miles Gavin can drive on 25 gallons, which is 8.5 miles/gallon * 25 gallons = 212.5 miles. Therefore, Gavin can drive 212.5 miles on 25 gallons of gas.

If x=6 and y=3 is 9_______________________________________

Answer:

x = 2

Step-by-step explanation:

The product of the external part times the entire secant of one secant is equal to the external part times the entire secant of the other secant, that is

(x + 4)(x + 5) = (x + 1)(x + 12) ← distribute factors on both sides

x² + 9x + 20 = x² + 13x + 12 ( subtract x² from both sides )

9x + 20 = 13x + 12 ( subtract 13x from both sides )

- 4x + 20 = 12 ( subtract 20 from both sides )

- 4x = - 8 ( divide both sides by - 4 )

x = 2

Answer:

Step-by-step explanation:

(2x-1)²=x²+4²

4x²-4x+1=x²+16

3x²-4x-15=0

a=3   b=-4   c= -15

D=b²-4ac

=16-4*3*(-15)=196

x1=-b+√D/2a=4+14/6=3

x2=-b-√D/2a=4-14/6=-10/6=-5/3

Answer:

x = 3

Step-by-step explanation:

Using Pythagoras' theorem on the right triangle, then

(2x - 1)² = 4² + x² ← expand parenthesis on the left side and simplify

4x² - 4x + 1 = 16 + x² ( subtract 16 + x² from both sides )

3x² - 4x - 15 = 0 ← in standard form

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 3 × - 15 = - 45 and sum = - 4

The factors are - 9 and + 5

Use these factors to split the x- term

3x² - 9x + 5x - 15 = 0 ( factor the first/second and third/fourth terms )

3x(x - 3) + 5(x - 3) ← factor out (x - 3)

(x - 3)(3x + 5) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = - [tex]\frac{5}{3}[/tex]

However, x must be greater than zero

Hence x = 3 cm

Since we are given a quadratic function, we need to write it using the standard form of quadratic function (parabola).

The given function is:

[tex]f(t)=3-2t.2t=+t[/tex]

The standard form of a parabola is:

[tex]f(t)=a^{2}+bx+c[/tex]

Where,

a is equal to the quadratic variable coefficient

b is equal to the linear variable coefficient

c is the constant number

So, writing the function in the standard form will be:

[tex]f(t)=3-2t*2t+t=3-4t^{2}+t=-4t^{2}+t+3[/tex]

[tex]f(t)=-4t^{2}+t+3[/tex]

Where,

An atom containing two more electrons than protons has a net charge of negative two (-2), as determined by the difference in number of positive protons and negative electrons.

An atom which has two more electrons than protons has a charge of -2. The charge of an atom is determined by the difference between the number of protons and electrons. Protons have a charge of +1 and electrons have a charge of -1. Hence, if the atom has two more electrons than protons, it will have a charge of -2 because electrons contribute a negative charge. For instance, for an atom with 2 protons (+2 charge) and 4 electrons (-4 charge), the overall charge would be -2.

An atom with 2 more electrons than protons will have a net charge of -2.

An atom is the basic unit of matter, consisting of a nucleus containing protons and neutrons, surrounded by electrons. Elements are defined by the number of protons in their atoms. An atom's charge is determined by the difference between the number of electrons and the number of protons. If an atom has 2 more electrons than protons, it will have a net charge of -2.

For example, let's consider the element oxygen (O). Oxygen normally has 8 protons and 8 electrons, resulting in a neutral charge. If we add 2 more electrons to oxygen, it will then have 10 electrons and still 8 protons, giving it a net charge of -2.

The measure of one interior angle of a 42 sided regular polygon is given by A = 171.428°

The sum of the interior angles of a polygon is given by the formula

Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

where n is the number of sides

θ = angle in degrees

Given data ,

Let the interior angle of the polygon be represented as A

Now , let the number of sides of the polygon be n = 42 sides

So , Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

On simplifying , we get

42θ = 180 ( 42 - 2 )

42θ = 180 ( 40 )

Divide by 42 on both sides , we get

A = 180 ( 40 ) / 42

A = 171.428°

Therefore , the value of A is 171.428°

Answer:

-3 143/1000

Step-by-step explanation:

To write -3.143 in its equivalent fraction form, multiply the whole number part by the place value of the decimal and add it to the decimal part multiplied by the place value. The resulting fraction is -3143/1000.

To write the decimal number -3.143 in its equivalent fraction form, we first need to determine the place value of each digit. The number -3.143 has three digits after the decimal point, so the fraction's denominator will be ten, raised to the power of three, which is 1000. The fraction's numerator will be the whole number part of the decimal (in this case, -3) multiplied by 1000, plus the decimal part (0.143) multiplied by 1000.

Therefore, the equivalent fraction form of -3.143 is:

-3.143 = (-3 * 1000 + 0.143 * 1000) / 1000 = -3143 / 1000

Answer:

B) x = 1

C) x = 4

Step-by-step explanation:

Given:

f(x) = 2x

g(x) = 2^x

We have to find at what value of x, the above two functions are equal in value.

Now we have to check with the each options.

When x = 0, f(0) = 2(0) = 0 ; g(0) = 2^0 = 1 [Anything power 0, is 1]

When x = 1, f(1) = 2(1) = 2 ; g(1) = 2^1 = 2.

when x = 2, f(2) = 2(2) = 4; g(2) = 2^2 = 4

when x = 3, f(3) = 2(3) = 6, g(3) = 2^3 = 8

when x = 4, f(4) = 2(4) = 8, g(4) = 2^4 = 16

The two functions are equal in value when x = 1 and x = 2.

Final answer:

The value(s) of x for which the equation f(x) = 2x and g(x) = 2ˣ are equal are x = 1 and x = 2, as those are the points where the two functions have the same value.

Explanation:

The student seems to be asking for which value(s) of x the equations f(x) = 2x and g(x) = 2ˣ are equal. To find the solution, we need to identify the point where the two functions intersect, by setting them equal to each other and solving for x.

So we set up the equation 2x = 2ˣ and look for solutions. At first glance, it seems there are two obvious solutions:

When x = 1, f(x) = 2 x 1 = 2 and g(x) = 2¹ = 2, so the statement f(x) = g(x) is true.

When x = 0, f(x) = 2 x 0 = 0 and g(x) = 2⁰ = 1, so the statement f(x) = g(x) is not true.

Testing the other provided options similarly, you'll find that:

For x = 2, f(x) = 4 and g(x) = 4, hence f(x) = g(x) is true.

For x = 3, f(x) = 6 and g(x) = 8, hence f(x) = g(x) is not true.

For x = 4, f(x) = 8 and g(x) = 16, hence f(x) = g(x) is not true.

The correct answers are x = 1 and x = 2, where the equation f(x) = g(x) holds true.

Step-by-step explanation:

The amount you will have after 10 years if you invest $2,500 into an account that pays 12% per year, compounded annually is given by

[tex]A=P(1+r\%)^t[/tex]

where [tex]t=10[/tex] years

[tex]r\%=0.12[/tex]

and P=$2,500

We substitute these values into the formula to obtain;

[tex]A=2500(1+0.12)^{10}[/tex]

This will give us;

[tex]A=2500(1.12)^{10}[/tex]

[tex]A=7764.6205[/tex]

We round to the nearest hundredth to obtain;

[tex]A=7,764.62[/tex]

The correct choice is A.

Answer:

r is the annual interest rate =0.12

t is time in years = 10

A is the final amount
