The length of the segment HI is 32.9

The Circle identities refer to a set of fundamental identities in trigonometry that relate to the some trigonometric functions of an angle in a right-angled triangle.

We know that the equation or formula of secant-tangent;

HI² = KI × JI

Given values:

KI = KJ + JI

KI = 21 + 24 = 45

JI = 24

put the all values in the secant-tangent equation above,

HI² = 45 × 24

HI² = 1080

Take the square root of both sides

HI = 32.9

Hence, the length of the segment HI is 32.9

In mathematics, a piece-wise-defined function is a function defined by multiple sub-functions, where each sub-function applies to a different  interval in the domain. Piece-wise definition is actually a way of expressing  the function, rather than a characteristic of the function itself.

Let 'x' be the  number of buses required to transport all the 9th graders. We can write the function in two parts, for 1st part  when the number of  students is less than or equal to 60 ( that is the capacity of one bus)  and for 2nd part  when it is greater than 60.

For x buses, each with a capacity of 60, we have:

Morgan's supply of raisins is approximately 4.62 pounds.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

Let's start by setting up an equation based on the given information:

14/48 + 38/48 = 5/x

Here, x represents the total supply of raisins in pounds.

To solve for x, we can first combine the fractions on the left-hand side of the equation:

52/48 = 5/x

Next, we can simplify by cross-multiplying:

52x = 48 x 5

52x = 240

Finally, we can solve for x by dividing both sides by 52:

x = 240/52

x ≈ 4.62

Answer:

To find the location of point L, we need to use the fact that point K lies on the perpendicular bisector of segment JL.

The perpendicular bisector of a segment is a line that passes through the midpoint of the segment and is perpendicular to the segment.

First, we can find the midpoint of segment JL:

Midpoint of JL = ((-5 + x)/2, (-8 + y)/2)

where (x, y) is the location of point L.

Since point K lies on the perpendicular bisector of JL, the line passing through K and the midpoint of JL will be perpendicular to JL.

The slope of the line passing through K and the midpoint of JL is:

m = (2 - (-8))/(-9 - (-5 + x)/2) = 10/(-9 - (5 - x)/2) = -4/(x - 7)

where we have used the fact that the line passing through K and the midpoint of JL is perpendicular to JL, so its slope is the negative reciprocal of the slope of JL.

Now, we can use the fact that the line passing through K and the midpoint of JL contains point K(-9, 2) to write the equation of the line:

y - 2 = m(x + 9)

Substituting the expression we found for m, we get:

y - 2 = (-4/(x - 7))(x + 9)

Simplifying this equation, we get:

y = -4x/ (x - 7) - 2

Now, we can substitute the x-coordinates of the answer choices to see which one gives us a valid y-coordinate:

A. (1, -2): y = -4(1)/(-6) - 2 = -1 --> Incorrect

B. (-1, -12): y = -4(-1)/(-8) - 2 = 1/2 --> Incorrect

C. (-3, -2): y = -4(-3)/(-10) - 2 = 6/5 --> Incorrect

D. (-3, -12): y = -4(-3)/(-10 - 4) - 2 = -26/7 --> Correct

Therefore, the location of point L is (-3, -12), which is answer choice D.

Answer:

To find the effective annual rate (EAR) of an account that pays interest at the nominal rate of 7% per year, compounded daily, we can use the following formula:

EAR = (1 + r/n)^n - 1

where r is the nominal annual interest rate (expressed as a decimal), and n is the number of times the interest is compounded in a year.

For daily compounding, n = 365 (since there are 365 days in a year), so we have:

EAR = (1 + 0.07/365)^365 - 1 = 0.0725 or 7.25%

To find the effective annual rate for hourly compounding, we need to adjust the value of n to account for the fact that interest is compounded more frequently. There are 365 days * 24 hours = 8,760 hours in a year, so we can use n = 8,760:

EAR = (1 + 0.07/8760)^8760 - 1 ≈ 0.0727 or 7.27%

Therefore, the effective annual rate for hourly compounding is approximately 7.27%.

a. The house has a square base with a side length of 50 feet, and the roof extends 1 foot beyond the walls on all sides. To find the length of each side of the base of the roof, we need to add 1 foot on each side of the square base.

Length of each side of the base of the roof = 50 ft + 1 ft + 1 ft = 52 ft

b. The slant height of the roof is 35 feet. To find the sum of the areas of the lateral faces of the pyramid, we can use the formula for the lateral area of a pyramid:

Lateral Area = (Perimeter of the base * Slant Height) / 2;

Since the base of the roof is a square, the perimeter is:

Perimeter = 4 * Side Length = 4 * 52 ft = 208 ft;

Now we can find the lateral area:

Lateral Area = (208 ft * 35 ft) / 2 = 3640 ft²;

c. The cost of installing a metal roof covering is $350 for every 100 square feet of roof. To find the cost of installing a metal roof covering on the house, we can use the following formula:

Cost = (Lateral Area / 100) * Cost per 100 square feet;

Cost = (3640 ft² / 100) * $350 = 36.4 * $350 ≈ $12,740;

The cost of installing a metal roof covering on the house is approximately $12,740.

The test statistic (37.96) is greater than the critical value (11.345), we can reject the null hypothesis and conclude that there is a significant relationship between admission date and birthday.

The test statistic for this test is calculated by summing the squared differences between the observed and expected frequencies in each category, divided by the expected frequency in that category. This formula is:

X² = ∑(observed - expected)² / expected

The degrees of freedom for this test are equal to the number of categories minus one (4-1=3). Using a significance level of 0.01, the critical value for this test is 11.345.

To calculate the test statistic for this sample, we first need to calculate the expected frequencies. Each category should have an expected frequency of 196/4 = 49.

Category 1: expected frequency = 49, observed frequency = 12

Category 2: expected frequency = 49, observed frequency = 22

Category 3: expected frequency = 49, observed frequency = 65

Category 4: expected frequency = 49, observed frequency = 97

Using the formula above, we can calculate the test statistic:

X² = [(12-49)²/49] + [(22-49)²/49] + [(65-49)²/49] + [(97-49)²/49]

X² = 37.96

Step-by-step explanation:

The logarithmic function can be written exponentially as follows.[tex]t = 8^y.[/tex]

Exponents and logarithms are inverse operations of one another. We can rewrite an equation in logarithmic form as log_a(b) = x if it has the form axe = b. A number's logarithm is the exponent that must be raised in order to obtain that number. For instance, since 102 = 100, log_10(100) = 2. Similar to this, we can express an equation in exponential form, such as axe = b, if it is in logarithmic form, such as log_a(b) = x. The inverse function of the logarithmic function is the exponential function. As a result, when we apply a logarithm to an exponential expression, the original exponent is returned, and the opposite is true.

The given logarithmic expression is [tex]log_{8}(t) = y.[/tex]

We know that if we have an equation in the form [tex]a^x = b[/tex], we can rewrite it in logarithmic form as [tex]log_a(b) = x[/tex] and vice versa.

Thus, [tex]log_{8}(t) = y[/tex]

(x - 3)(x + 6) can be written in vertex form as y = (x - (-3/2))² - 20.25

What is the vertex form?

The vertex form of a quadratic function is a way of writing a quadratic function in form f(x) = a(x - h)² + k where (h, k) is the vertex of the parabola, a is a coefficient that determines the shape and direction of the parabola, and x is the input variable.

Expanding (x - 3)(x + 6), we get:

x² + 6x - 3x - 18 = x² + 3x - 18

To write this expression in vertex form, we need to complete the square. To do this, we add and subtract (3/2)² = 2.25 inside the parentheses:

x² + 3x - 18 + 2.25 - 2.25 = (x² + 3x + 2.25) - 20.25

Now, we can write the expression in vertex form:

y = (x - (-3/2))² - 20.25

The null hypothesis is that there is no difference in the means.

The test statistic for the two-sample t-test is given as:

where;

Substituting the given values:

t = (1245 - 1208) / (√(1346 * (1/12 + 1/11)))

t = 2.29

The calculated t-value (2.29) is greater than the tabulated t-value at a 5% level of significance for 21 degrees of freedom, hence, we reject the null hypothesis and conclude that the means are different.
