Answer:

0.04

Step-by-step explanation:

12^(-x) = 5   (taking log on both sides)

log [ 12^(-x)] = log 5

-x log 12 = log 5

-x = log 5 / log 12

x = - (log 5/log12)

x = -0.6477

12^(2x)

= 12^[2(-0.6477)]

Answer: 91/288

Step-by-step explanation: To divide mixed numbers, first write the mixed numbers as improper fractions.

We can do this by multiplying the denominator by the whole number and then adding the numerator. Then, we put our new numerator over our old denominator.

So here, we can write 1 and 5/8 as the improper fraction 13/8 and we can write 5 and 1/7 as the improper fraction 36/7.

So here, we have 13/8 ÷ 36/7.

Dividing by a fraction is the same as multiplying by the reciprocal of that fraction.

So here, 13/8 ÷ 36/7 is the same as 13/8 × 7/36.

So now we are simply multiplying fractions and we do this by multiplying across the numerators and multiply across the denominators.

[tex]\frac{13}{8} x \frac{7}{36} = \frac{91}{288}[/tex]

So now we have 91/288 which is in lowest terms.

This means that 1 and 5/8 divided by 5 and 1/7 is 91/288.

1st rectangle:

Length = 11 ft

Width = 3 ft

Area [tex]=11\cdot 3=33 \ ft^2[/tex]

2nd rectangle:

Length = 3 ft

Width = 2 ft

Area [tex]=3\cdot 2=6 \ ft^2[/tex]

Total area:

[tex]33+6=39\ ft^2[/tex]

The first five terms of the sequence are:

6 , 8 , [tex]\frac{32}{3}[/tex] , [tex]\frac{128}{9}[/tex] , [tex]\frac{512}{27}[/tex]

Step-by-step explanation:

The recursive formula of the sequence is

[tex]a_{1}=6[/tex] and [tex]a_{n}=\frac{4}{3}*a_{n-1}[/tex]

To find the first five terms do that:

∵ [tex]a_{1}=6[/tex]

∴ [tex]a_{2}=\frac{4}{3}*6[/tex]

∴ [tex]a_{2}=8[/tex]

∵ [tex]a_{2}=8[/tex]

∴ [tex]a_{3}=\frac{4}{3}*8[/tex]

∴ [tex]a_{3}=\frac{32}{3}[/tex]

∵ [tex]a_{3}=\frac{32}{3}[/tex]

∴ [tex]a_{4}=\frac{4}{3}*\frac{32}{3}[/tex]

∴ [tex]a_{4}=\frac{128}{9}[/tex]

∵ [tex]a_{4}=\frac{128}{9}[/tex]

∴ [tex]a_{5}=\frac{4}{3}*\frac{128}{9}[/tex]

∴ [tex]a_{5}=\frac{512}{27}[/tex]

The first five terms of the sequence are:

6 , 8 , [tex]\frac{32}{3}[/tex] , [tex]\frac{128}{9}[/tex] , [tex]\frac{512}{27}[/tex]

Slope is already given in the question so we only need to solve for the y-intercept.

Slope intercept form: y = mx + b

m = slope

b = y-intercept

-3/5 = -0.6

1 = -0.6(1) + b

1 = -0.6 + b

1 + 0.6 = -0.6 + b + 0.6

1.6 = b

Now, write in slope-intercept form.

y = -3/5x - 1.6

Answer:

Domain:  -∞ < x < +∞

Range : 2 ≤ f(x) < +∞

Step-by-step explanation:

See the graph attached to this question.

The two arrow shows the graph of a function y = f(x).

Now, the value of x varies from +∞ to -∞.

So, the domain of the function is -∞ < x < +∞

Again from the graph the range of the function i.e. values of y varies from 2 to +∞ and including 2.

Therefore, the range of the function is 2 ≤ f(x) < +∞ (Answer)

The equation of the circle in standard form is: (x + 2)² + (y - 1)² = 1

What is the equation of the circle?

The general form of the equation of a circle is:

(x - h)² + (y - k)² = r²

Where;

(h, K) is the coordinate of the center of the circle.

r is radius.

To find the equation of the circle in standard form, we need to determine the center and radius of the circle.

Since the center of the circle lies on the line y = 3x + 1 and is tangent to the x-axis at (-2,0), we can determine that the center of the circle is (-2,1) and the radius is 1.

Therefore, the equation of the circle in standard form is:

(x + 2)² + (y - 1)² = 1

Answer:

The measure of angle F is m∠F=130°

Step-by-step explanation:

step 1

Find the measure of angle E

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

DF=EF ----> given problem

so

Triangle DEF is an isosceles triangle

m∠D=m∠E

we have

m∠D=25°

substitute

m∠E=25°

step 2

Find the measure of angle F

we know that

The sum of the measures of the interior angles in a triangle must be equal to 180 degrees

so

m∠D+m∠E+m∠F=180°

substitute the values

25°+25°+m∠F=180°

50°+m∠F=180°

m∠F=180°-50°

m∠F=130°

Answer:

The linear equation is 1.25x + 0.5x = y

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Price of ride ticket at country fair = US$ 1.25

Total spent by Tom for rides and admission= US$ 43.75

Number of ride tickets bought by Tom = 25

Price of admission is the same for everyone

Total cost = y

Number of tickets = x

2. Let's find out the cost of the admission:

Total cost of ride tickets + Total cost of admission = Total cost of rides tickets and admission

Replacing with real values:

1.25 * 25 + Cost of admission * 25 = 43.75

31.25 + 25 * Cost of admission = 43.75

25 * Cost of admission = 43.75 - 31.25 (Subtracting 31.25 at both sides)

25 * Cost of admission = 12.50

Cost of admission = 12.50/25 (Dividing by 25 at both sides)

Cost of admission = 0.50

3. Let's write a linear equation to determine the cost for rides tickets and admission:

Total cost of ride tickets + Total cost of admission = Total cost of rides tickets and admission

Total cost = y

Number of tickets = x

1.25x + 0.5x = y

Final answer:

The costs for members and nonmembers of a local fitness center will be the same after attending 6 aerobics classes. Members have an initial $12 membership fee plus $2 per class, while nonmembers pay $4 per class.

Explanation:

To find the number of aerobics classes for which the cost for members and nonmembers will be the same, we need to set up an equation that compares the two cost structures. For members, the cost is a $12 membership fee plus $2 per class, which we can express as Cm = 12 + 2n, where Cm is the cost for members and n is the number of classes. For nonmembers, the cost is $4 per class, so we can express that as Cnm = 4n, where Cnm is the cost for nonmembers.To find the number of classes where costs are the same, we set Cm equal to Cnm:

Subtract 2n from both sides: 12 = 2n

Divide both sides by 2: n = 6

Therefore, the costs for members and nonmembers will be the same when they attend 6 aerobics classes.

Step-by-step explanation:

The image attached shows the context that the problems refered.

Notice that two acute angles from those triangles are congruent, just because their complement are also congruent.

[tex]\angle AOB \cong \angle COD[/tex]

[tex]\angle AOB= \angle COD=90\° - a[/tex]

Remember that the tangent function is defined as

[tex]tan(\theta)=\frac{Opposite \ Leg}{Adjacent \ Leg}[/tex]

Replacing each equiavlence, we have

[tex]tan(90-a)=\frac{6}{4}=\frac{10}{x}[/tex]

Then, we solve for [tex]x[/tex]

[tex]\frac{6}{4} =\frac{10}{x}\\ x=\frac{40}{6}\\ x \approx 6.67 ft[/tex]

Thereofre, the answer is 6.67 feet, approximately.

Step-by-step explanation:

Final answer:

The mathematics optimization problem involves finding the maximum sum of the square of one non-negative number and the cube of the other, with their total being 4. Calculus is applied by taking the derivative of the function representing the sum, setting it to zero to find critical points, and checking the second derivative to ensure a maximum is found. The optimized numbers are x and 4-x, based on the critical point found.

Explanation:

To solve the optimization problem, we need to use calculus to find the maximum value of the sum of the square of one number and the cube of the other, given that the sum of the two numbers is 4. Let's call these numbers x and y, with x + y = 4. We want to maximize S = x^2 + y^3.

Since x + y = 4, we can express y as y = 4 - x. Substituting this into S, we have S = x^2 + (4-x)^3. This becomes a function of one variable.

To find the maximum value, we differentiate S with respect to x, set the derivative equal to zero, and solve for x. We can check the second derivative to ensure it is a maximum. The function S' will have a maximum when the first derivative is zero (S'(x) = 0) and the second derivative is negative (S''(x) < 0).

Therefore, the two non-negative numbers that maximize S are x and 4-x, with x being the value at which S' equals zero with S'' negative.

Final answer:

To solve the system of equations -3x - 4y = 2 and 6x + 6y = -6, multiply the first equation by 2 to eliminate the coefficients of y, and then add the equations together. The solution is x = -2 and y = 1.

Explanation:

To solve the system of equations:

-3x - 4y = 2

6x + 6y = -6

First, multiply the first equation by 2 so that the coefficients of y will cancel when adding the equations together.

-6x - 8y = 4

Next, add the modified first equation to the second equation.

(-6x - 8y) + (6x + 6y) = 4 + (-6)

-8y + 6y = -2

-2y = -2

Divide both sides of the equation by -2 to solve for y.

y = 1

Substitute the value of y back into either equation to solve for x.

-3x - 4(1) = 2

-3x - 4 = 2

-3x = 6

x = -2

The solution to the system of equations is x = -2 and y = 1.
