The diagram shows the line starting at P, ending at R, and with a segment of length PQ created by drawing an arc intersecting the line.

A line segment is a path between two points that can be measured. Since line segments have a defined length, they can form the sides of any polygon.

The task is to draw an arc that intersects the line starting at P and ending at R, and create a segment with length PQ. The diagram shows the line starting at P, ending at R, and with a segment of length PQ created by drawing an arc intersecting the line.

Hence, the diagram shows the line starting at P, ending at R, and with a segment of length PQ created by drawing an arc intersecting the line.

Answer:

\(\frac{1}{9^3}\) or \(\frac{1}{729}\)

Step-by-step explanation:

When we have an exponent that is a negative, it is the same thing as 1 over the positive exponent. So, we move 9^-3 into 1/9^3 and then we evaluate the exponent to get our answer.

to have $110,000 available for the child's education in 12 years at 6% interest, we need to set aside $54,661.55 now. This assumes that the interest rate remains constant over the 12-year period, which may not be the case in reality.

To calculate how much money must be set aside at 6% interest, we can use the future value formula:

\(FV = PV*(1 + r)^n\)

where:
FV = future value (the amount of money we want to have in the future)
PV = present value (the amount of money we need to set aside now)
r = interest rate per period (in this case, per year)
n = number of periods (in this case, the number of years until the child starts college)

In this case, we want to have $110,000 in the future, the child is 6 years old now, and we assume that the child will start college at age 18, which is 12 years from now. The interest rate is given as 6% per year.

So, we can plug in the values into the formula:

\(110,000 = PV*(1 + 0.06)^12\)

Simplifying the right-hand side of the equation:

110,000 = PV x 2.012594

Dividing both sides by 2.012594:

PV = 110,000 / 2.012594

PV = $54,661.55 (rounded to the nearest cent)

Therefore, to have $110,000 available for the child's education in 12 years at 6% interest, we need to set aside $54,661.55 now. This assumes that the interest rate remains constant over the 12-year period, which may not be the case in reality.

La forma estándar de una ecuación de un círculo es% 28x-h% 29% 5E2 +% 2B +% 28y-k% 29% 5E2 + = + r% 5E2

donde Pt (h, k) es el centro y r es el radio

x ^ 2 + y ^ 2-10x + 4y + 4 = 0

completando los cuadrados para ponerlos en la forma estándar

x ^ 2 -10x + y ^ 2 + 4y + 4 = 0

(x-5) ^ 2-25 + (y +2) ^ 2-4 + 4 = 0

 (x-5) ^ 2 + (y + 2) ^ 2 = 25

El centro es (5, -2) radio = 5

The radius, circumferance and Coordinates of center of the circle are 3, 6π and O(1, - 2) respectively.

        (x - h)² + (y - k)² = r²

Given is the equation of a circle as -

x² + y² - 2x + 4y - 4 = 0

We need to change the equation of the circle into standard form as -

(x - h)² + (y - k)² = r²

The given equation is -

x² + y² - 2x + 4y - 4 = 0

We can write it as -

(x - 1) + (y + 2) = 9

So, the radius will be -

r² = 9

r = 3

The circumferance will be -

C = 2πR

C = 2π x 3

C = 6π

Coordinates of center -

O(1, - 2)

Therefore, the radius, circumferance and Coordinates of center of the circle are 3, 6π and O(1, - 2) respectively.

The magnitude and direction form with the magnitude rounded to the nearest tenth and the direction rounded to the nearest degree 5.4<cos335°<, sin335°

What is direction ?

Direction is characterized as the course that anything follows, the route that must be taken to go to a particular location, the direction in which something is beginning to take shape, or the direction you are facing. When you turn right instead of left, that is an illustration of direction.

The basis of the x, y, and z directions of a line or unit vector is identified by the number triplet known as the direction number. They are easily identified as a percentage of a unit vector.

u = 7cos300°i + 7sin300j

v = 4cos70i + 4sin70 j

u = 7*0.5i + 7*(-√3/2)j

  = 3.5i - 6.062j

v = 1.368i + 3.758j

u + v =(3.5+1.368)i +(-6.062+3.758)j

        = 4.868i +(-2.304)j

Magnitude of (u+v) = √(4.868)² +(2.304)²

                               = 5.385 ≈ 5.4

For direction

tanФ = y/x

        = -2.304/4.868

    Ф = -25.327

∴(u+v) is in 4th Quandrant

∴ Ф = 360 - 25.327

     = 334.672

The formula to calculate the arc angle from radius and central angle is simply by finding their product. The formula for arc length is -

S = r×theta, where r is radius and theta is the central angle

Now we are given angle in degree and we need to convert it in radian. So the formula is -

Central angle = 60 × π/180

Central angle = π/3 radians

Answer:

\(w =7\ or\ w =3\)

Step-by-step explanation:

Given

The right question is:

\(\log(w^2+ 21) = \log(10w)\)

Required

Solve for w

\(\log(w^2+ 21) = \log(10w)\)

Cancel log on both sides

\(w^2+ 21 = 10w\)

Equate to 0

\(w^2 - 10w+ 21 = 0\)

Split

\(w^2 - 3w - 7w+ 21 = 0\)

Factorize

\(w(w - 3) - 7(w-3) = 0\)

Factor out w - 3

\((w - 7)(w-3) = 0\)

Step-by-step explanation:

The table gives us the squares of certain values, and can be used to find the square root of certain values as well. For example, if 6² = 36, we can say that √36 = 6. Given this information, we can say that √47.6 is 6.9, and √49 = 7. If we look at the square root graph (√x=y), we can see that as x goes up, y goes up, and when x goes down, y goes down.

Therefore, we can say that the square root of 48 is between 6.9 and 7. We don't know exactly where it is, as there is no formula given to find it, so what Gina can do is go through the values between 6.9 and 7.0 and look for √48

The first step in evaluating the expression 3x{9-(4+2)/2 is to simplify the innermost parentheses. By performing operations within parentheses first, we can simplify the expression and make it easier to evaluate.

To begin, we evaluate the expression within the parentheses (4+2), which equals 6. Thus, the original expression becomes 3x{9-6/2}.

The next step is to simplify the division operation. We divide 6 by 2, resulting in 3. Now the expression becomes 3x{9-3}.

The subsequent step is to simplify the subtraction operation. We subtract 3 from 9, giving us 6. The expression now becomes 3x6.

Finally, we multiply 3 by 6, yielding a final result of 18. Therefore, the evaluation of the expression 3x{9-(4+2)/2 is equal to 18.

By simplifying the parentheses, performing the division, and evaluating the subtraction, we systematically reduce the expression to its simplest form. Following the order of operations (also known as PEMDAS or BODMAS), which prioritizes parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right), ensures an accurate evaluation of the expression.

Answer: 12 seedlings sorry if this is wrong  

Step-by-step explanation:

The only true statement about the domain of the given function is:

B. f(x) is negative for all x < -5

The domain of a function is defined as the set of values that we can possibly plug into our function. This set is the x values in a function such as f(x).

Now, we are given the function as:

f(x) = \(\frac{2}{x^{2} } + 3x - 10\)

When x < -5, we have:

f(-4) = \(\frac{2}{(-4)^{2} } + 3(-4) - 10\)

f(-4) = -21.875

This suggests that for all values below x = -5 will result in negative values

When x > 2

f(3) = \(\frac{2}{3^{2} } + 3(3) - 10\)

f(3) = -0.78

Thus, it will get positive for higher values but it can also be negative as seen here.

A function that represents a reflection of \(f(x) = \frac{3}{8} (4)^x\) across the y-axis include the following: D. \(g(x) = \frac{3}{8} (4)^{-x}\).

In Mathematics and Geometry, a reflection over or across the y-axis or line x = 0 is represented and modeled by this transformation rule (x, y) → (-x, y).

This ultimately implies that, a reflection over or across the y-axis or line x = 0 would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the parent exponential function, we would have the following transformed exponential function:

(x, y)                                              →                 (-x, y).

\(f(x) = \frac{3}{8} (4)^x\)                               →              \(g(x) = \frac{3}{8} (4)^{-x}\)
