To find the coordinates of a point on a circle with radius 10 corresponding to an angle of 325 degrees, you can use the following formula:

(x, y) = (r * cos(θ), r * sin(θ))

where (x, y) are the coordinates of the point, r is the radius of the circle, and θ is the angle in radians.

To convert the angle from degrees to radians, you can use the following formula:

θ (radians) = θ (degrees) * (π / 180)

Substituting the values into the formula and converting the angle to radians, you get:

(x, y) = (10 * cos(325 * (π / 180)), 10 * sin(325 * (π / 180)))

= (-5.5, 9.5)

Therefore, the coordinates of the point on the circle with radius 10 corresponding to an angle of 325 degrees are (-5.5, 9.5).

What are the coordinates point?

The coordinates of a point in a coordinate system are a set of numerical values that specify the position of the point in relation to an origin. In a two-dimensional coordinate system, such as the Cartesian coordinate system, a point is represented by an ordered pair (x, y), where x and y are the coordinates of the point. The x-coordinate represents the point's position along the horizontal axis, and the y-coordinate represents the point's position along the vertical axis.

Answer:

2^3 = 8

Step-by-step explanation:

=============================================

Explanation:

1/4 = 0.25

1/2 = 0.5

24 & 1/2 = 24.5

The rope is 24.5 ft long and you want sections of length 0.25 ft each.

Let x be the number of sections we can make.

1 section is 0.25 ft long

x of them combine to 0.25x feet long

Set this equal to 24.5 and solve for x

0.25x = 24.5

x = (24.5)/(0.25)

x = 98

There will be 98 sections of equal length (each being 0.25 ft)

------------------

Another way to look at it:

1 foot of rope gets you four sections of 0.25 ft each

24 feet of rope gets you 24*4 = 96 sections.

Another 0.5 ft adds another 0.5*4 = 2 sections to get to a total of 96+2 = 98

Based on the given parameters, the value of the money to invest initially is $994.8

The given parameters about the compound interest are

Principal Amount, P = $2130

Interest Rate, R = 6.4%

Time, t = 12

Number of times, n = 12 i.e. monthly

To calculate the amount, we have:

A = P + CI

Where

C = P(1 + R)^t

So, we have

A = P(1 + R)^t

This can be rewritten as

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

Substitute the known values in the above equation

2130 = A * (1 + 6.4%/12)^(12*12)

So, we have

A = 2130/[(1 + 6.4%/12)^(12*12)]

Evaluate the expression

A = 994.8

Hence, the amount of the investment is $994.8

In a one-tailed T-test, if the test statistics and the t-value are under the null hypothesis, then p-value = ρ > to alternate hypothesis is true.

Critical zones in hypothesis testing are ranges of distributions where the values correspond to outcomes that are statistically significant. Analysts set the significance level (alpha) and whether the test is one-tailed or two-tailed in order to determine the size and location of the key regions.

The likelihood of rejecting an accurate null hypothesis is the significance level.

A test statistic's sample distribution assumes that the null hypothesis is true.

As a result, you need to shade the necessary fraction of the distribution to depict the crucial areas on the distribution for a test statistic. You shade 5% of the distribution using the typical significance threshold of 0.05.

The center of the circle lies on the x-axis. The radius of the circle is 3 units. The radius of this circle is the same as the radius of the circle whose equation is x² + y² is 9.

The radius of a circle is the distance between the circle's centre and any point on its circumference. It is usually represented by the letters 'R' or 'r'. This number is significant in almost all circle-related formulas. A circle's area and circumference are also measured in terms of radius.

The standard equation of a circle is expressed as:

x² + y²+2gx+2fy+C=0

Centre is (-g, -f)

radius = √g²+f²-C

Given a circle whose equation is 2+ y²-2x-8=0.

Get the centre of the circle

2gx = -2x

2g=-2

g=-1

Similarly, 2fy = 0

f=0

Centre = (-(-1), 0) = (1, 0)

This shows that the center of the circle lies on the x-axis

r = radius = √g²+f²-C

radius = √1²+02-(-8)

radius =√9 = 3 units

The radius of the circle is 3 units.

For the circle x² + y² = 9, the radius is expressed as:

2. The interior angles of a triangle will equal 180 degrees.

With these two pieces of knowledge, you can substitute the value of A as "180 - (x+110)" because A = 180-(x+110)

Step-by-step explanation:

Answer:

To solve this equation, you can use cross multiplication to eliminate the fractional terms. Doing so gives you 11 * 17 = 13 * x. Solving for x gives you x = (11 * 17)/13. Dividing these two numbers gives you approximately x = 8.46. Rounding this number to the nearest tenth gives you x = 8.5. Therefore, the value of x that makes the equation true is approximately 8.5.

The p-value of the test is 0, which is less than the standard significance level of 0.05, thus we can conclude that the proportion respondents who rated themselves as above average drivers is greater than 0.7.

We may test the following using the example data:

In reality, 812.35 respondents identified as better drivers than average.

We can infer that the proportion of respondents who rated themselves as above average drivers is greater than 0.7 because the test's p-value is 0, which is less than the standard significance level of 0.05. 77% of the sample of 1055 adults rated themselves as above average drivers, so 0.77(1055) = 812.35.

As a result, 812.35 respondents actually assessed themselves as better drivers than average.

We examine if the proportion is 7/10=0.7 at the null hypothesis.

H0 is that, with p = 0.7.

If the proportion is larger than 70%, we test for the alternative hypothesis, which is H1:p>=0.7.

The test statistic comes from:

The parameters for this issue are p dash = 0.77, p = 0.7, and n = 1055.

As a result, the test statistic's value is:

z = 351.758 root

The likelihood of discovering a sample proportion above 0.77, calculated as 1 minus the p-value of z = root of 351.758, is the test's p-value.

According to the z-table, the p-value for z = root of 351.758 is 1, and 1 - 1 equals 0.

Since the test's p-value is zero and is below the conventional significance level of 0.05, we can infer that a higher proportion of respondents than 0.7 evaluated themselves as above-average drivers.

A function showing the value of the account after t years, where the annual growth rate can be found from a constant in the function is f(t) = 2900 × (1.0624)^t and APY is 6.24%.

Compound interest in simple words is the interest earning for your savings with the interest which those savings earn.

The formula for calculating the amount in Compound Interest is,

A = P( 1 + [tex]\frac{r}{n}[/tex] )ⁿᵇ

where A is the amount, P is the principal, r is the rate of interest, n is the number of times interest compounded in a year and b is the number of years.

Here, P = $2900, r = 6.1% = 0.061, n = 4 (quarterly) and b = t years

A = 2900 (1 + [tex]\frac{0.061}{4}[/tex])^4t

A = 2900 (1.0153)^4t

A = 2900 × (1.0624)^t

So A can be said as a function of t.

f(t) = 2900 × (1.0624)^t

Percentage of growth per year (APY) = ( 1 + [tex]\frac{r}{n}[/tex] )ⁿ - 1

                                                              = (1 + [tex]\frac{0.061}{4}[/tex])⁴ - 1

                                                              = 1.0624 - 1

                                                              = 0.0624 = 6.24%

Hence the function of the value of the account after t years is f(t) = 2900 × (1.0624)^t, where the value 1.0624 is a constant.
