Hello!

Given the function, [tex]f(x) = 2(\frac{1}{2})^{x}[/tex], notice that the function f(x) is an exponential function.

All exponential functions have a horizontal asymptote at y = 0, and this means that the graph never goes over the line y = 0. Therefore, the range is less than zero, but never equal to zero.

Also, this means that the domain of the function f(x) is all real numbers because as we substitute positive x-values into the function, the graph goes closer to zero, but never across zero. But, if we substitute negative x-values into the equation, it goes to infinity.

Therefore, the answer is choice C. The domain of f(x) is all real numbers, and the range is y > 0.

We want to find the domain and range of the given equation.

We will see that the correct option is C:

Domain: all real numbers;

Range: y > 0

First, we need to define what these are.

For a given function y = f(x), the domain is the set of all the possible x-values we can input on the function, and the range is the set of the possible outcomes.

We have the exponential equation:

f(x) = 2*(1/2)^x

To get the domain we start by assuming that the domain is the set of all real numbers, and then we see if the equation has a problem for a given value of x, then we remove that from the domain.

But here we have x on the exponent, so there are no value of x that causes problems, thus the domain is the set of all real numbers.

To get the range we can look at the graph, we can see that the range goes from near 0 to infinity, so we can say that:

range = y > 0.

(note that the function tends asymptotically to zero, meaning that it never becomes equal to zero).

Then the correct option is C:

Domain: all real numbers;

Range: y > 0

Answer:

The statement is true.

Step-by-step explanation:

Given the statement we have to tell the statement is true or false.

The statement is

"The circumcenter of a triangle is the center of the only circle that can be circumscribed about it"

The circumcenter of triangle is the point in the triangle where the perpendicular bisectors of sides intersect.

The center of the circumscribed circle is the the point where the perpendicular bisectors of the sides meet.

Hence,

The circumcenter is also center of the triangle's circumcircle - the circle that pass through all three of the triangle's vertices.

Therefore, the given statement is true.

Answer:

True

Step-by-step explanation:

Circumcircle: A circle drawn outside a circle is called circumcircle and its center is called circum-center.

Circum-center of triangle:It is the point where the perpendicular bisectors of a  triangle intersect.

The circumcenter of triangle is also the center of triangle's circumcircle.

The circumcenter is equidistant from each vertex of the triangle.

The circumcenter of right triangle falls on the side opposite the right triangle.

Hence, the circumcenter of a triangle is the center of the only circle that can be circumscribed about it.

Answer:

When P and Q are equal there is no solution exist.

For example - (0,0) , (1,1)  

Step-by-step explanation:

Given : Equation [tex]Px+40=Qx+20[/tex]

To find : Which values of P and Q result in an equation with no solutions?

Solution :

In the given equation [tex]Px+40=Qx+20[/tex]        

P, Q, x are variable.

We have to find the values at which the equation has no solutions.  

[tex]Px+40=Qx+20[/tex]

[tex]Px+20=Qx[/tex]

[tex]20=Qx-Px[/tex]

[tex]20=x(Q-P)[/tex]

If Q=P then (Q-P)x = 0 for all x

Thus the original equation has no solutions.

For example,

Put x=1 and Q=1

[tex]x+40=x+20[/tex]

[tex]40\neq 20[/tex]

There is no solution.

The system of linear inequalities that are graphed are {y≥3x−2  and x+2y≤4

In order to get the required system of inequalities, we need to get the equations of both lines.

For the line with having the coordinate points (0, 2) and (4, 0)

The standard form of the expression will be y = mx+b

m = 0-2/4-0

m = -2/4

m = -1/2

The y-intercept "b" is 2 (the point where the line cuts the y-axis)

The equation of the line will be y = -1/2x + 2

2y = -x + 4

x + 2y = 4

Since the line is a solid line and shaded towards the negative side of the graph, the given inequality expression will be x+2y ≤ 4

For the line with having the coordinate points (0, -2) and (2, 4)

The standard form of the expression will be y = mx+b

m = 4+2/2-0

m = 6/2

m = 3

The y-intercept "b" is -2 (the point where the line cuts the y-axis)

The equation of the line will be y = 3x-2

Since the line is a solid line and shaded towards the positive side of the graph, the given inequality expression will be y≥3x−2

Answer: red = 10, orange = 20

Step-by-step explanation:

Let R represent the # of red skittles and G represent the # of orange skittles

there are 10 less red skittles than orange skittles: R = G - 10

orange skittles are twice the red skittles: G = 2R

Use substitution to solve the system:

 R = (2R) - 10

-R   -R        

0  = R - 10

+10     +10

10 = R

G = 2R   = 2(10)   = 20

Answer:  The correct option is

(C) [tex]y=\dfrac{2}{3}x-2.[/tex]

Step-by-step explanation:  We are given to select the equation of a line in slope-intercept form with slope [tex]\dfrac{2}{3}[/tex] and y-intercept at (0, -2).

We know that

the slope-intercept form of the equation of a line with slope m and y -intercept at the point (0, c) is given by

[tex]y=mx+c.[/tex]

For the given line, we have

[tex]\textup{slope, }m=\dfrac{2}{3},\\\\\\\textup{y-intercept},~(0,c)=(0,-2)\\\\\Rightarrow c=-2.[/tex]

Therefore, the equation of the line in slope-intercept form is

[tex]y=mx+c\\\\\Rightarrow y=\dfrac{2}{3}x+(-2)\\\\\\\Rightarrow y=\dfrac{2}{3}x-2.[/tex]

Thus, the required equation of the line in slope-intercept form is [tex]y=\dfrac{2}{3}x-2.[/tex]

Option (C) is CORRECT.

Answer:

1. You divide by 3 then multiply by 1 and multiply by 3 again

2. Slope of -3

3. Slope of 0

Step-by-step explanation:

You need to know the 30-60-90 triangles rules for lengths. (b, b√3, 2b)

the given side length of corresponds to the 30° angle.  So, b = 8

side y corresponds to the 60° angle so it is b√3. Since we determined that b = 8, then b√3 is 8√3.

side x corresponds to the 90° angle so it is 2b.  Since we determined that b = 8, then 2b = 2(8) = 16

Answer: x = 16, y = 8√3

Final answer:

To find the dimensions of the field with a perimeter of 600 feet where the length is three times the width, solve the equation derived from the perimeter formula. The width comes out to be 75 feet and the length 225 feet.

Explanation:

The question is about finding the dimensions of a rectangular field that is three times as long as it is wide, with a total perimeter of 600 feet. First, let's denote the width of the field as W and the length as 3W since the length is three times the width. The formula for the perimeter of a rectangle is 2(length + width), which in this case is 2(3W + W) = 8W. Given that the perimeter is 600 feet, we can set up the equation 8W = 600. Solving this for W gives us W = 75 feet. Therefore, the length, being three times the width, is 225 feet.

So, the dimensions of the field are 75 feet in width and 225 feet in length.

The expression for the cost of Taxi B is 0.40x + 2.  The expression for the cost of Taxi A is 0.20x + 4.  The inequality asks for when the cost of Taxi B will be greater than Taxi A, so you write it as 0.40x + 2 > 0.20x + 4,  or  0.20x + 4 < 0.40x + 2.

The answer is B) 0.20x + 4 < 0.40x + 2.

Answer: B. [tex]0.20x+4<0.40x+2[/tex]

Step-by-step explanation:

let x denotes the number of mile taxi runs.

Given : Taxi A charges $0.20 per mile and an initial fee of $4.

i.e. the expression to show total charge by Taxi A will be :[tex]0.20x+4[/tex]

Taxi B charges $0.40 per mile and an initial fee of $2.

i.e. the expression to show total charge by Taxi B will be :[tex]0.40x+2[/tex]

Now, the inequality that can determine when the cost of Taxi B will be greater than Taxi A will be :-

[tex]0.20x+4<0.40x+2[/tex]

Hence, B is the correct answer.

[tex]a_n=5n-1\\\\a_1=5(1)-1=5-1=4\\\\a_2=5(2)-1=10-1=9\\\\a_3=5(3)-1=15-1=14\\\\a_4=5(4)-1=20-1=19\\\\Answer:\ B.\ \{4,\ 9,\ 14,\ 19\}[/tex]

Subtract the cost from the revenue:

(-0.32x^2+270x) - (70x+52)

270x - 70x = 200x

The answer would be -0.32x^2 + 200x + - 52

Answer:

P(x) = -0.32x² + 200x + (-52)

Step-by-step explanation:

A company sells lab equipment. Daily revenue and costs are modeled by the function as given in the question.

Revenue:             R(x) = -0.32x² + 270x

Cost :                   C(x) = 70x + 52

Here x = Number of units sold.

Now we have to determine the function P(x) for daily profit.

Since Profit = Revenue - Cost

            P(x) = R(x) - C(x)

            P(x) = (-0.32x² + 270x) - (70x + 52)

                   = -0.32x² + 270x - 70x - 52

            P(x) = -0.32x² + 200x - 52

Therefore, answer will be P(x) = -0.32x² + 200x + (-52)

Step-by-step explanation:

The fraction of those who are scared of spiders and also scared of snakes is 1/2.

A fraction is a way of representing a part of a whole or a division of quantities. It consists of two components: a numerator and a denominator, separated by a horizontal line called a fraction bar.

We have,

1/3 of the children are scared of spiders and 1/6 of both snakes and spiders, we can find the fraction of those who are scared of spiders and snakes by dividing the overlap by the total number scared of spiders.

Fraction scared of spiders and snakes

= (Overlap) / (Total scared of spiders)

Overlap = 1/6

Total scared of spiders = 1/3

Fraction scared of spiders and snakes = (1/6) / (1/3) = (1/6) * (3/1) = 1/2

Therefore, the fraction of those who are scared of spiders and also scared of snakes is 1/2.

Final answer:

Half of the children who are scared of spiders are also scared of snakes, calculated by dividing the fraction of children scared of both by those scared of spiders.

Explanation:

To find the fraction of those who are scared of spiders that are also scared of snakes, we start with the information that 2/3 of the children are scared of snakes, 1/3 are scared of spiders, and 1/6 are scared of both snakes and spiders. Since we want to find out the fraction of those scared of spiders (1/3 of the total) who are also scared of snakes, we focus on the 1/6 portion that represents children scared of both. This fraction is relative to the whole group. To express it as a fraction of just those scared of spiders, we divide the fraction of both phobias (1/6) by the fraction scared of spiders (1/3).

Calculation: (1/6) ÷ (1/3) = (1/6) * (3/1) = 1/2.

Therefore, 1/2 of those who are scared of spiders are also scared of snakes.
