Answer:

A represents f(x) and B represents g(x)

Step-by-step explanation:

choose a value for x, substitute , say x = 1 into both f(x) and g(x) , then check the values obtained on the graph.

f(x) = 100 × [tex](\frac{3}{5}) ^{1}[/tex] = 100 × [tex]\frac{3}{5}[/tex] = 20 × 3 = 60

thus (1, 60 ) is a point on the graph of f(x)

the point (1, 60 ) is on graph A

g(x) = 100 × [tex](\frac{2}{5}) ^{1}[/tex] = 100 × [tex]\frac{2}{5}[/tex] = 20 × 2 = 40

thus (1, 40 ) is a point on the graph of g(x)

the point (1, 40 ) is on graph B

The required factors of the polynomial by grouping are  (x-3)(x^2 + 2).

To factor polynomial equations, a specialized approach is called grouping. It can be applied to polynomials with four terms as well as quadratic equations. Although they differ significantly, the two approaches are comparable.The first two terms and the final two terms are combined: p(x)=(x3 - 4x2) + (3x - 12), and we then identify the shared

factors as follows: p(x) = x2(x - 4) + 3(x - 4). (x - 4).

x^3 - 3x^2 + 2x -6

(x-3)(x^2 + 2)

Thus, required factors are (x-3)(x^2 + 2).

Step-by-step explanation:

The constant doesn't have a letter attached to it

38, 39, 40, 37, 38, and so forth. The perimeter of the supplied figure must be determined. = 38.97 units. As a result, 38.97 units make up the perimeter.

The circumference of a shape is known as its perimeter. The lengths of all four sides must be added in order to get a rectangle's or square's perimeter.

The total length of all a polygon's sides is its perimeter. The polygon's sides are PT, TS, SR, RQ, and QP. We apply the distance formula to get a side's length:

d =[tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

There are points that correspond to each vertex in the polygon:

P (-2,11)

T (8, 7)

S (1, 7)

R (2, 0)

Q (-4,5)

So, using the distance formula and the vertex positions of side PT, we can determine its length: The total length of all a polygon's sides is its perimeter. The polygon's sides are PT, TS, SR, RQ, and QP. We apply the distance formula to get a side's length:

d =[tex]\sqrt{(x2-x1)^{2}+(y2-y1)\x^{2} }[/tex] ≤ b r/≥ d=[tex]\sqrt{(8-(-2)^{2})+(7-11)^{2} }[/tex]  ≤b r/≥

d=[tex]\sqrt{116}[/tex]

There are points that correspond to each vertex in the polygon:

P (-2,11)

T (8, 7)

S (1, 7)

R (2, 0)

Q (-4,5)

So, using the distance formula and the vertex positions of side PT, we can determine its length:

P  = (-2, 11)

T  = (8, 7)

The length of PT is [tex]\sqrt{116}[/tex]

The other 4 sides are handled in the same way, and the results are as follows:

TS = [tex]\sqrt{49}[/tex]

SR = [tex]\sqrt{50}[/tex]

RQ = [tex]\sqrt{61}[/tex]

QP = [tex]\sqrt{40}[/tex]

You may calculate the perimeter by adding all the sides:[tex]\sqrt{116}[/tex]+[tex]\sqrt{49}[/tex]+[tex]\sqrt{50}[/tex]+[tex]\sqrt{61}[/tex]+[tex]\sqrt{40}[/tex] = 38.97

The solution is 39 units if you round off.

A 140-pound person will typically burn 4 calories per mile of walking at a rate of 3 miles per hour.

Walking at a pace of 3 miles per hour results in an average calorie burn of 4 for a 140-pound person. This person would therefore burn around 112 calories in a period of 30 minutes. On the other hand, a 200-pound person burns roughly 5 calories per minute, or 159 calories every 30 minutes.

An average walking speed of 3 miles per hour (or 120 steps per minute) is recommended for health reasons. That is a mile that takes 20 minutes. You must increase your pace to 4 miles per hour (135 steps per minute), or a 15-minute mile, to walk for weight loss.

An exponential decay function to model the situation is f(x) = 49(0.7)^x.

The average rate of change over 1 ≤ x ≤ 4 is -7.5.

The average rate of change over 5 ≤ x ≤ 7 is -1.4.

The rate of change decreases as x increases.

In Mathematics, an exponential function can be modeled by using this mathematical expression:

f(x) = ab^x

Where:

Since the initial value is 49 and the decay factor is 0.7, an exponential function that models the situation is given by:

f(x) = ab^x

f(x) = 49(0.7)^x

When x = 1, the value of f(x) is:

f(1) = 49(0.7)^1

f(1) = 34.3.

When x = 4, the value of f(x) is:

f(4) = 49(0.7)^4

f(4) = 11.7649.

For the average rate of change over 1 ≤ x ≤ 4, we have:

Average rate of change = [f(b) - f(a)]/(b - a)

Average rate of change = [11.7649 - 34.3]/(4 - 1)

Average rate of change = -22.5351/3

Average rate of change = -7.5

For the average rate of change over 5 ≤ x ≤ 7, we have:

Average rate of change = [f(b) - f(a)]/(b - a)

Average rate of change = [49(0.7)^7 - 49(0.7)^5]/(7 - 5)

Average rate of change = [4.0354 - 8.2354]/2

Average rate of change = -4.2/3

Answer: The diagonal AC of a square bisects the square and the midpoint of the diagonal is the center of the square. Since the center of the square is the midpoint of the diagonal, we can find the midpoint of AC by averaging the x-coordinates and y-coordinates of A and C.

The coordinates of the center of the square is ( (2+(-2))/2 , (4+1)/2) = (0, 2.5)

Since a square is a special case of rectangle, which means all sides are equal, the length of the side of the square is the distance between A and C.

Using the distance formula, we can find the length of the side of the square:

d = sqrt( (2-(-2))^2 + (4-1)^2 ) = sqrt(4^2 + 3^2) = sqrt(16+9) = sqrt(25) = 5

The coordinates of the vertex D can be found by subtracting half of the side length from x and y coordinates of the center point.

D(0-5/2, 2.5 - 5/2) = (-2.5, 0.5)

The coordinates of the vertex B can be found by adding half of the side length from x and y coordinates of the center point.

B(0+5/2, 2.5 + 5/2) = (2.5, 5.5)

So the remaining vertices are (2.5, 5.5) and (-2.5, 0.5)

The salesman needs to sell $25937.5 to reach his needed monthly income needs.

Commission, also known as sales commission, is a payment given to employees based on the sales they make.

Given that, A local salesman receives a base salary of $925 monthly. He also receives a commission of 8% on all sales over $1250.

Monthly salary = fixed part + commission part

The fixed salary is $925.

The commission part is 8% on all sales over $1250

Let x = amount of sales, and x must be greater than $1250.

Then, the amount of sales over $1250 is x - 1250.

He earns 8% on that amount, so the commission part is 8%(x - 1250),

or 0.08(x - 1250).

Monthly salary = fixed part + commission part

Monthly salary = 925 + 0.08(x - 1250)

925 + 0.08(x - 1250) = 2900

0.08x = 2075

x = 25937.5

The value of x, given the angle measures in Triangle ABC, can be found to be 22.

Triangle ABC is a right angled triangle which means that ACB has the angle measure of 90 degrees. This means that the angle measures left will add up to :

= Sum of interior angles in triangle - Angle ACB

= 180 - 90

= 90 degrees

If the sum of 2 x and ( 3 x - 20 ) adds up to 90 degrees, the value of x would then be:

90 = 2 x + ( 3 x - 20 )

2 x + 3 x - 20 = 90

2 x + 3 x = 90 + 20

5 x = 110

x = 110 / 5

x = 22

Answer:

[tex]r=\left(\dfrac{y}{P}\right)^{\frac{1}{x}}-1[/tex]

Step-by-step explanation:

Given exponential function:

[tex]f(x)=P(1+r)^x[/tex]

Replace f(x) with y:

[tex]y=P(1+r)^x[/tex]

Divide both sides by P:

[tex]\dfrac{y}{P}=(1+r)^x[/tex]

Take natural logs of both sides:

[tex]\ln \left(\dfrac{y}{P}\right)=\ln (1+r)^x[/tex]

[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]

[tex]\ln \left(\dfrac{y}{P}\right)=x \ln (1+r)[/tex]

Divide both sides by x:

[tex]\dfrac{1}{x}\ln \left(\dfrac{y}{P}\right)=\ln (1+r)[/tex]

[tex]\textsf{Apply the power law}: \quad n \ln x=\ln x^n[/tex]

[tex]\ln \left(\dfrac{y}{P}\right)^{\frac{1}{x}}=\ln (1+r)[/tex]

Raise both sides to power of e:

[tex]\large\text{$e^{\ln \left(\frac{y}{P}\right)^{\frac{1}{x}}}=e^{\ln (1+r)}$}[/tex]

[tex]\textsf{Apply the power law}: \quad e^{\ln x}=x[/tex]

[tex]\left(\dfrac{y}{P}\right)^{\frac{1}{x}}=1+r[/tex]

Subtract 1 from both sides:

[tex]\left(\dfrac{y}{P}\right)^{\frac{1}{x}}-1=r[/tex]

Therefore, the equation to find r is:
