Answer: Option d.

Step-by-step explanation:

To find the domain of the function we should look for the values for which the denominator is equal to zero, because the division by zero is not allowed.

We know by definition that the function [tex]e^x[/tex] is always greater than zero for all x.

We know that the constant c is greater than zero (c>0).

Then, the expression [tex]e^x+c[/tex] is never equal to zero.

Therefore, it does not exist a value for x that makes the denominator 0. Then, the domain of the function is all real numbers.

The answer is the option d.

Answer:

[tex]\frac{\pi }{10}[/tex]

Step-by-step explanation:

The area (A) of the sector is calculated using the formula

A  = area of circle × fraction of circle

let x be the measure of the central angle, then

A = πr² × [tex]\frac{x}{2\pi }[/tex] ← substitute values

5π = π × 10² × [tex]\frac{x}{2\pi }[/tex]

5π = 100π × [tex]\frac{x}{2\pi }[/tex] (cancel 50π and 2π )

5π = 50x ( divide both sides by 50 )

x = [tex]\frac{5\pi }{50}[/tex] = [tex]\frac{\pi }{10}[/tex] ← central angle

Final answer:

The measure of the central angle that forms a sector with an area of 5π in a circle of radius 10 is 18 degrees.

Explanation:

To calculate the measure of the central angle that forms the sector of a circle with a radius of 10 units and an area of 5π, we need to use the formula for the area of a sector, which is A = (θ/2) × r², where A is the area of the sector, θ is the central angle in radians, and r is the radius of the circle.

First, let's substitute the given values into the formula:

Now, we can set up the equation:

5π = (θ/2) × 10²

5π = (θ/2) × 100

To find the central angle, we solve for θ:

θ = (2 × 5π) / 100

θ = 0.1π radians

To convert radians to degrees, we use the conversion factor that 180° = π radians:

θ in degrees = 0.1π × (180/π)

θ in degrees = 18°

Therefore, the measure of the central angle that forms the sector is 18 degrees.

The domain of Function A, defined as f(x) = -3x + 2, is all real numbers, as it is a linear function with no restrictions on x-values. Function B's domain would depend on its specific definition but is also valid as long as each input maps to a unique output.

The domains of Function A and Function B can be compared based on the definition of a function's domain. The domain is all the input values (x-values) for which a function is defined. Since Function A is defined as f(x) = -3x + 2, it is a linear function without any restrictions on the x values, meaning the domain of Function A is all real numbers.

The description of Function B isn't provided in the question, but from the referenced information, we can understand that Function B is also a function as long as each element of its domain maps to a unique value in its range.

Were we to have the specifics of Function B, we could determine if it also has a domain of all real numbers or whether it has a more restricted domain, such as when a function includes a square root or division by variables which would exclude certain x-values to avoid undefined expressions.

Answer:

-1066.65  to 2 decimal places.

Step-by-step explanation:

(−800)+(−200)+(−50)+(−12.5)+...

This is a Geometric series with common ratio  r =(-200) / ) / (-800)  = 0.25 and first term  a1 = -800.

Sum of n terms = a1 * (1 - r^n) / (1 - r)

Sum of 8 terms = -800 * (1 - 0.25^8) /  (1 - 0.25)

= -800 * 1.333313

= -1066.65.

The sum of the first eight terms of the geometric sequence is given by: −1066.65

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The sum of the first n terms is given by:

[tex]S_n = \frac{a_1(r^n - 1)}{r - 1}[/tex]

In this problem, we have that the first term and the common ratio are, respectively:

[tex]a_1 = -800, q = \frac{-200}{-800} = 0.25[/tex]

Hence, the sum of the first eight terms is given by:

[tex]S_n = \frac{-800(0.25^8 - 1)}{0.25 - 1 } = −1066.65[/tex]

   Looking at the figure, the rectangle has the vertexes (2,1), (3,-3), (-5,-5) and (-6,-1). The parallelogram has the vertexes (2,7), (3,3), (3,-3), and (2,1).

The area of a parallelogram is base times height. We have 2 vertical lines at x=2 and x=3, so the height is 1. And the length of the line from (3,3) to (3,-3) is 6, so the base is 6. Therefore the area of the parallelogram is 1*6 = 6.

  The rectangle is a tad trickier since it's not aligned with either the x or y axis. But we can use the Pythagorean theorem to get the lengths.

 L = sqrt((2 - -6)^2 + (1 - -1)^2)

 L = sqrt(8^2 + 2^2)

 L = sqrt(64 + 4)

 L = sqrt(68) = 2*sqrt(17)

  W = sqrt((2-3)^2 + (1- -3)^2)

 W = sqrt((-1)^2 + 4^2)

 W = sqrt(1 + 16)

 W = sqrt(17)

  And the area is length * width, so:

 2*sqrt(17)*sqrt(17) = 2 * 17 = 34

  And the total area is the sum of the areas, so

 34 + 6 = 40

  So the area of the figure is 40 square units.

Answer:

Graph both equations and find the X value when the lines cross.

See attached picture of the graph

X = 1

Or you could take logarithms of both sides where log(a^b) = b loga to also find the value of x.

Answer:

x = 1

Step-by-step explanation:

Given in the question,

[tex](16/9)^{-2x+5} = (3/4)^{(x-7)}[/tex]

Take logarithm on both sides

Apply power rule of logarithm

(-2x+5)ln(16/9) = (x-7)ln(3/4)

cross multiply

(-2x+5)/(x-7) = [tex]\frac{ln(3/4)}{ln(16/9)}[/tex]

-1/2 = (-2x+5)/(x-7)

-(x-7) = 2(-2x+5)

[tex]A(x)=(6x^2+5x-21)cm^2[/tex]

If [tex]x=2[/tex]: [tex]A(2)=13cm^2[/tex]  

Step-by-step explanation:

The area of the rectangle can be calculated with the formula:

[tex]A=lw[/tex]

Being l the lenght of the rectangle and w the width of the rectangle.

In this case, the lenght and the width are represented with:

Answer:

1 hour and 45 mins

Step-by-step explanation:

As mentioned,

Starting time = 2:30 PM

Ending time = 4:15 PM

The given time is in hours and minutes, to calculate the duration of movie, time should be converted into a same unite minutes.

1 hour = 60 minutes

Therefore,

2:30 = 2 hours and 30 mins = 2*60 + 30 mins = 150 mins

4:15 = 4 hours and 15 mins = 4*60 + 15 mins = 255 mins

The duration = Ending time - Starting time

=> 255 - 150

=> 105 mins

or

Step-by-step explanation:

One number is 5 less than a second number.

a = b - 5

:

Twice the second number is 8 less than 4 times the first.  

2b = 4a - 8

replace a with (b-5)

2b = 4(b-5) - 8

2b = 4b - 20 - 8

2b - 4b = -28

-2b = -28

b = 14

then

a = 9

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let's call the first number "x" and the second number "y"

x = y - 5 (the first number is 5 less than the second number)

2y = 4x - 4 (twice the second number is 4 less than 4 times the first)

We can use substitution to solve for one of the variables.

Substituting the first equation into the second equation, we get:

2y = 4 (y - 5) - 4

Simplifying this equation , we get

2y = 4y - 24

2y - 4y = -24

-2y = -24

y = 12

Now that we know that the second number is 12, we can use the first equation to find the first number:

x = y - 5

x = 12 - 5

x = 7

Hence , the two numbers are 7 and 12

A kite's symmetrical structure typically forms isosceles triangles due to equal side lengths. Asymmetrical kites generate scalene triangles with varying side lengths, influencing triangle types and angles within based on side intersections.

A kite, with its distinct shape formed by two pairs of adjacent congruent sides, generates triangles within. These triangles can exhibit various properties based on the kite's symmetry. If the kite is symmetrical, the triangles formed tend to be isosceles due to the equal side lengths.

However, asymmetrical kites can yield scalene triangles with sides of varying lengths. The relationship between the kite's structure and the triangle types arises from the lengths and intersections of its sides.

Symmetry tends to create similar or congruent triangles, while asymmetry leads to triangles with differing side lengths. Consequently, the angles within these triangles vary based on the intersection of the kite's sides, resulting in a mix of acute, obtuse, or right angles.

Answer:

Part 1. 0.9259 % per year

Part 2. P = 281.4e^(0.009 259t); 338.6 million  

Step-by-step explanation:

Data:

P₀ = 281.4 million

P  = 308.7 million

Part 1. Growth rate

t = 2010 - 2000 = 10 yr

        P = P₀e^(rt)

308.7 = 281.4e^(10r)

e^(10r) = 1.0970

     10r = ln1.0970

        r = (ln1.0970)/10 = (0.092 59)/10 = 0.009 259  

        r = 0.9259 % per year

The 10-year continuous growth rate is 0.9259 % per year.

Part 2. Population model

The population model is

P = 281.4e^(0.009 259t)

where P is in millions and t is the number of years since 2000.

By 2020,

P = 281.4e^(0.009 259 × 20) = 281.4e^0.1852 = 281.4 × 1.203

P = 338.6 million

The estimated population in 2020 is 338.6 million.

(b) What is a convergent series? What is a divergent series?

Answer:

The correct answer is 6.

Step-by-step explanation:

To find this, first find f(-3)

f(x) = -3x + 9

f(-3) = -3(-3) + 9

f(-3) = 9 + 9

f(-3) = 18

Now we do the same for f(7)

f(x) = -3x + 9

f(7) = -3(7) + 9

f(7) = -21 + 9

f(7) = -12

Now we add them together

18 + -12 = 6

The value of f(?3) + f(7) - f(-3) + f(7) is -24.

To find the Value of f(?3) + f(7) - f(-3) + f(7), we need to substitute the given values into the function f(x) = -3x + 9.

Substituting -3 for x, we get f(?3) = -3(-3) + 9 = 18.
Substituting 7 for x, we get f(7) = -3(7) + 9 = -12.
Substituting -3 for x and adding the results, we get f(-3) = -3(-3) + 9 = 18.
Substituting 7 for x, we get f(7) = -3(7) + 9 = -12.

Now, let's calculate the Value of the expression:
f(?3) + f(7) - f(-3) + f(7) = 18 + (-12) - 18 + (-12) = -24

Step-by-step explanation:

The dress will cost $50.40 after a 20% discount from the original price of $63. You calculate this by finding 20% of $63, which is $12.60, and subtracting it from $63.

When a store is having a 20% off sale, it means that the original price of the item is reduced by 20%. In this case, you need to calculate 20% of $63, which is the original price of the dress.

To find 20% of $63, you multiply 63 by 20/100 (because percent means per hundred). That is: 63 * 0.20 = $12.60.

So the amount of the discount is $12.60. Therefore, you subtract this discount from the original price of the dress to find out the new price: 63 - 12.60 = $50.40.

So, after a 20% off sale, the dress will cost $50.40.
