Simplify (4with an expponent of 4)−1 exponent too

Triangle LMO is congruent to NMO because they are reflections of eachother.

One identity that we can write here is:

cos²(θ/2) = - sin²(θ/2) + 1

Here we want to find something that is equal to cos²(θ/2) for every value of theta, that will be an identity.

The general identity for trigonometric functions is:

cos²(θ) + sin²(θ) = 1

So we can rewrite this as:

cos²(θ) = - sin²(θ) + 1

If instead of theta, the argument is theta over two, we could rewrite this as:

cos²(θ/2) = - sin²(θ/2) + 1

That is the identity.

True; the point (-1/5, -3/2) does lie on the graph of f(x) = 7.5x.

From the question, we have the following parameters that can be used in our computation:

f(x) = 7.5x

The point is given as

(x, y) = (-1/5, -3/2)

To determine whether the point (-1/5, -3/2) lies on the graph of f(x) = 7.5x, we can substitute x = -1/5 into the equation and see if it gives us y = -3/2.

f(x) = 7.5x

By substitution, we have

f(-1/5) = 7.5(-1/5)

Evaluate

f(-1/5) = -1.5

Express as fraction

f(-1/5) = -3/2

So, the point (-1/5, -3/2) does lie on the graph of f(x) = 7.5x.

Complete question

True or False. The point (-1/5, -3/2) lies on the graph of f(x).

Where f(x) = 7.5x

Answer:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = the final amount

P = the principal (initial amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years)

In this case, we have:

P = $200.00

r = 0.09 (9% expressed as a decimal)

n = 1 (compounded annually)

t = 5 years

Plugging these values into the formula, we get:

A = $200.00(1 + 0.09/1)^(1*5)

A = $200.00(1.09)^5

A = $200.00(1.538624)

A = $307.72

Therefore, after 5 years, Megan will have $307.72 in her account.

The x intercept and the y intercept for 6x - 3y = -12 is x = 0.5y + 2 and y = 2x - 4.

The term “intercept” refers to the location where a line or curve crosses a graph's axis. The x-intercept is the point at which the x-axis is crossed. The y-intercept is the point at which the y-axis is crossed.

The line's steepness is measured by its slope (m). It is the difference between the y-coordinate change and the corresponding x-coordinate change. For 6x - 3y = 12, just enter the above coordinates and solve for m to obtain the slope.

To solve for x, we solve the equation so the variable x is by itself on the left side:

6x - 3y = 12

x = 0.5y + 2

To solve for y, we solve the equation so the variable y is by itself on the left side:

6x - 3y = 12

The comparisons of the fractions given above is enumerated below.

1) To compare 1/8 and 1/9, I can find a common denominator by multiplying the denominators together. The common denominator is 8 x 9 = 72.

Then, I can convert each fraction to have a denominator of 72 by multiplying the numerator and denominator of each fraction by the appropriate factor. The result is 9/72 and 8/72. Since 9/72 is bigger than 8/72, I know that 1/8 is smaller than 1/9.

2) To compare 7/8 and 8/9, I can find a common numerator by multiplying the numerators together. The common numerator is 56. Then, I can convert each fraction to have a numerator of 56 by multiplying the numerator and denominator of each fraction by the appropriate factor. The result is 49/56 and 64/72. Since 64/72 is bigger than 49/56, I know that 8/9 is bigger than 7/8.

3) To compare 15/38 and 5/13, I can find a common numerator by multiplying the numerators together.

The common numerator is 195. Then, I can convert each fraction to have a numerator of 195 by multiplying the numerator and denominator of each fraction by the appropriate factor.

The value of the function (f+g)(x) = x² + 4x - 4.

An output variable and one or more input variables are at least two of the variables that make up a function. A mathematical equation may have any number of variables and says that two expressions are equivalent (none, one, or more). A function is frequently expressed as an equation, however not all equations are functions.

Given that,

f(x) = 4x + 2

g(x) = x² - 6

(f+g)(x) = f(x) + g(x) = 4x + 2 + x² - 6

The total amount that Rahul will have is 108,006.20.

Compound interest is a type of interest where the interest earned on a principal amount is added to the principal, and the new total amount becomes the basis for calculating interest in the next period.

In other words, the interest is earned not only on the principal amount but also on the accumulated interest.

The formula for compound interest is:

Here we have, Rahul's plans to invest $25,000 in a retirement account that compounds 6% monthly.

From the data,

The principal amount, P = 25000

Rate of interest, r = 6% = 6/100 = 0.06

Time period, t = 25 years  

Number of compounds, n = 12  [ Since compounded annually ]

By using the formula, A = P (1 + r/n)^(n×t)  

A = 25000 [ 1 + 0.6/12]⁽¹²ˣ²⁵⁾

A = 25000 [ 1 + 0.005]⁽³⁰⁰⁾

The ratio for the area and the ratio for the circumferences of the circles are 9 : 1 and 6 : 1 respectively.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

If the radius of one circle is three times the radius of another circle, then we can use this information to determine the ratio of the areas of the circles and the ratio of the circumferences of the circles without knowing their actual measurements.

Let's call the radius of the smaller circle "r" and the radius of the larger circle "3r".

Ratio of areas -

The area of a circle is proportional to the square of its radius, so the ratio of the areas of the two circles is -

= (area of larger circle) / (area of smaller circle)

= (π(3r)²) / (πr²)

= 9r²/r²

= 9/1

Therefore, the ratio of the areas of the two circles is 9:1.

Ratio of circumferences -

The circumference of a circle is proportional to its radius, so the ratio of the circumferences of the two circles is -

= (circumference of larger circle) / (circumference of smaller circle)

= 2π(3r) / 2πr

= 6r/r

= 6/1

Therefore, the ratio of the circumferences of the two circles is 6:1.

Step-by-step explanation:

N′(−11, −2), M′(−8, −1), O′ (−11, −5)

The image coordinates of N′M′O′ if the preimage is translated 7 units to the left are N′(−11, −2), M′(−8, −1), O′ (−11, −5). This is calculated by subtracting 7 from the x-coordinate of each point in the original triangle NMO. For example, the x-coordinate of point N in the original triangle is -4, so the x-coordinate of point N′ in the translated triangle is -4 - 7 = -11. The y-coordinate of point N does not change, so the y-coordinate of point N′ is also -2.

Answer:

To translate the triangle 7 units to the left, we need to subtract 7 from the x-coordinates of each vertex:

N' = (N_x - 7, N_y) = (-4 - 7, -2) = (-11, -2)

M' = (M_x - 7, M_y) = (-1 - 7, -1) = (-8, -1)

O' = (O_x - 7, O_y) = (-4 - 7, -5) = (-11, -5)

Therefore, the image coordinates of N'M'O' are (-11, -2), (-8, -1), and (-11, -5).

So the answer is N′(−11, −2), M′(−8, −1), O′ (−11, −5).

a. The amplitude of the function y = 4 sin [(2π / 365)(x - 79)] + 12 is 4.

b. The period of the function y = 4 sin [(2π / 365)(x - 79)] + 12 is 365 days.

c. There are approximately 16 hours of daylight on the longest day of the year.

d. There are approximately 8 hours of daylight on the shortest day of the year.

e. The graph for the function is obtained.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The function is given as y = 4 sin [(2π / 365)(x - 79)] + 12.

a. The amplitude of the function is the coefficient of the sine function, which is 4.

Therefore, the amplitude of the function is 4.

b. The period of the function is given by the formula: period = (2π/b), where b is the coefficient of x in the sine function.

In this case, b = (2π/365), so the period is -

period = (2π / (2π/365)) = 365

Therefore, the period value is 365 days.

c. The longest day of the year occurs on the summer solstice, which is around June 21.

On this day, x = 171 (assuming January 1 is x = 1). Plugging x = 171 into the function gives -

y = 4 sin [(2π/365)(171 - 79)] + 12 = 15.998 hours

Therefore, the number of hours for daylight is 16 hours.

d. The shortest day of the year occurs on the winter solstice, which is around December 21.

On this day, x = 355. Plugging x = 355 into the function gives -

y = 4 sin [(2π/365)(355 - 79)] + 12 = 8.002 hours

Therefore, the number of hours for daylight is 8 hours.

e. To graph the function for one period, we need to find the values of y for x ranging from 1 to 365.

We can use a graphing tool or software to plot the function.

The graph is plotted.

The x-axis represents the number of days after January 1, and the y-axis represents the number of hours of daylight.

The function oscillates between 8 and 16 hours of daylight over the course of one year, with the maximum occurring around day 171 and the minimum occurring around day 355.

The graph shows that the function is periodic, with a period of 365 days, as expected.

Therefore, the function is plotted.

A fundamental idea in physics, density is utilised in many branches of research and engineering, including the construction of effective engines and turbines, calculating the buoyancy of objects in fluids, and forecasting the behaviour of materials under stress.

Given that, average density of the entire pyramid is 4.7g/cm3 and that the bottom part has a mass of 972.8g.

The density is given as:

density = mass/volume

Substituting the value we have:

4.7g/cm3 = 972.8g/volume

volume = 207.23 cubic cm.

For the top part, density of 2.9g/cm3 and a mass of 92.8g. :

density = mass/volume

2.9g/cm3 = 92.8g/volume

volume = 32 cubic cm.

The percent of the top part with respect to total volume is:

percentage = (volume of top part / total volume) x 100

total volume = volume of top part + volume of bottom part

total volume = 32 cm3 + 207.23 cm3

total volume = 239.23 cm3

percentage = (32 cm3 / 239.23 cm3) x 100

Answer:

One solution at (2, -1)

Step-by-step explanation:

You will want to write the equations for both pairs of points:

(-2,-3) and (0,-2)

The slope is the change in y over the change in x.  The first number of the ordered pairs is the x value and the second number in the ordered pair is the y values.  Find the change by subtraction

[tex]\frac{-2 - -3}{0 - -2}[/tex] = [tex]\frac{-2+ 3}{0 + 2}[/tex] = [tex]\frac{1}{2}[/tex]

The slope (m) is 1/2.

The y intercept is when x = 0.  In the point (0,-2) x is 0, so the y-intercept is -2.

The y-intercept (b) is -2.

y = mx + b  Substitute 1/2 for m and -2 for b

y = [tex]\frac{1}{2}[/tex]x - 2

(0,3) and (1,1)

The slope is

[tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = -2

The slope is --2.

The y intercept is 3.

y = mx + b  Substitutes -2 for m and 3 for b.

y = -2x + 3

Set the 2 equation equal to each other and solve for x.

-2x + 3 = 1/2 x -2   Multiply all the way through by 2 to clear the fraction.

-4x + 6 = x - 4   Add 4x to both sides

-4x + 4x + 6 = x + 4x -4

6 = 5x -4  Add 4 to both sides

6 + 4 = 5x - 4 + 4

10 = 5x  Divide both sides by 5

2 = x

Take either of the two original equations and substitute 2 for x and solve for y

y = -2x + 3

y = -2(2) + 3

y = -4 + 3

y = -1

The solution is (2,-1)

Given is the recursive formula, we need to find the first five terms of the  sequence,

1) a₁ = 12, aₙ = 3 and aₙ₋₁-21 :-

a₂ = a₂₋₁ -21

= 12-21

= -9

a₃ = a₃₋₁-21

= -9-21

= -30

a₄ = a₄₋₁-21

= -30-21

= -51

a₅ = a₅₋₁-21

= -51-21

= -72

Hence, the first five terms of the given sequence are, 12, -9, 30, -51, -72....
