A particular sawdust pile has a base diameter of 35 feet when the height is 30 feet. Find the volume of this sawdust pile when it is 40 feet high.

By using the properties of logarithms, The logarithm "log₅(98)" can be written as log₅(2) + log₅(7) + log₅(7).

We use the "product' and "quotient" logarithmic identities to write log₅(98) in terms of log₅(2) and log₅(7):

⇒ logₐ(b × c) = logₐ(b) + logₐ(c)      ....(product rule)

⇒ logₐ(b/c) = logₐ(b) - logₐ(c)           ...(quotient rule)

First, we write the number "98" as the product of 2 and 7, which is :

⇒ log₅(98) = log₅(2 × 7 × 7),

Using the product rule, we can split this into three logarithms;

⇒ log₅(2 × 7 × 7) = log₅(2) + log₅(7) + log₅(7),

So, we have,

⇒ log₅(98) = log₅(2) + log₅(7) + log₅(7),

Therefore, log₅(98) is equal to log₅(2) + log₅(7) + log₅(7).

If the radius of smaller-saw is 1.25 in, and radius of larger-saw is 2 inches, then larger-saw is 4.71 inches greater the smaller-saw.

The "Circumference" of a circle is defined as the distance around the boundary of a circle, it is also called perimeter of circle;

The diameter of the smaller saw can be calculated as:

⇒ diameter = 2 × radius = 2 × 1.25 inches = 2.5 inches;

The diameter of the larger saw is 1.5 inches greater than the diameter of the smaller saw, which means,

⇒ diameter of larger saw = diameter of smaller saw + 1.5 inches,

⇒ diameter of larger saw = 2.5 inches + 1.5 inches = 4 inches;

So, Circumference of circle is = 2 × π × radius;

The Circumference of "smaller-saw" = 2 × 3.14 × 1.25 inches,

⇒ circumference of smaller saw = 7.85 inches;

circumference of "larger-saw" = 2 × 3.14 × 2 inches

⇒ circumference of larger saw = 12.56 inches;

The difference in circumference between the two saws is:

⇒ circumference of larger saw - circumference of smaller saw

⇒ 12.56 inches - 7.85 inches = 4.71 inches;

Therefore, the circumference of the larger saw is 4.71 inches greater than the circumference of the smaller saw.

The function with y-intercept as 1 is h(x) = 0.5(2)ˣ + 0.5.

The y-intercept is the point where the graph intersects the y-axis. In other words, the y-intercept of a function is the value of y when x = 0.

Therefore, let's find the function with y-intercept as 1.

Hence,

h(x) = 0.5(2)ˣ + 0.5

Let's make x = 0 to check if the value of y = 1

Therefore,

h(x) = 0.5(2)ˣ + 0.5

h(0) = 0.5(2)⁰ + 0.5

h(0) = 0.5(1) + 0.5

h(x) = 0.5 + 0.5

The proportion of homes in Oregon heated by natural gas is different than the reported national average of 45%.

Null hypothesis: The proportion of homes in Oregon heated by natural gas is the same as the reported national average of 45%.

Alternative hypothesis: The proportion of homes in Oregon heated by natural gas is different than the reported national average of 45%.

We can use a two-tailed z-test to test this hypothesis.

The test statistic is calculated as:

z = (p - P) / √[P(1-P)/n]

where p is the sample proportion, P is the hypothesized population proportion (0.45), and n is the sample size.

Using the values given in the problem, we have:

p = 175/314 = 0.557

P = 0.45

n = 314

Plugging these values into the formula, we get:

z = (0.557 - 0.45) / √[0.45(1-0.45)/314] = 3.039

Using a standard normal distribution table, we find that the probability of getting a z-value of 3.039 or higher (in absolute value) is less than 0.005.

Since the significance level is 0.05, which is greater than the p-value, we can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis.

Therefore, the proportion of homes in Oregon heated by natural gas is different than the reported national average of 45%.

The correct answer is C. The circumference of a circle varies directly as the radius.

It is calculated by multiplying the diameter of a circle by pi, or by measuring the length of a curved line that encloses the shape.

The relationship between the circumference of a circle and its radius is a linear equation, where the circumference is equal to two times pi times the radius, or C = 2πr.

The circumference of a circle varies directly as the radius, meaning that if the radius of a circle is doubled, the circumference will also double.

This linear relationship can be used to approximate the value of pi, which is a constant ratio between the circumference and the diameter of any circle.

Therefore, the statement that justifies why the measurements of the circumference and radii of circles with different areas can be used to approximate the value of pi is that the circumference of a circle varies directly as the radius.

A- Tanya's gross income for the first year was $7,940, and b- her net income was $5,840 after subtracting her total expenses.

a. To calculate Tanya's gross income for the first year, we need to multiply the rent per month by the number of months the house was rented:

Gross income from rent = $620/month x 7 months = $4,340

Tanya also paid $175/month in average expenses for the whole year, so her total expenses were:

Total expenses = $175/month x 12 months = $2,100

Adding the mortgage interest paid, Tanya's gross income for the first year was:

Gross income = $4,340 + $3,600 = $7,940

b. To calculate Tanya's net income or net loss, we need to subtract her total expenses from her gross income:

Net income = Gross income - Total expenses

Net income = $7,940 - $2,100

Net income = $5,840

Therefore, Tanya's net income for the first year was $5,840.

The proof of cot²(x) - tan²(x) = csc²(x) - sec²(x) is the help of trigonometry

identity and Pythagorean identity .

A trigonometric identity is an equation that is true for all values of the variables in the equation, where the variables are trigonometric functions such as sine, cosine, tangent, cotangent, secant, or cosecant.

The Pythagorean identity is a fundamental trigonometric identity that relates the three basic trigonometric functions: sine, cosine, and tangent, in terms of the unit circle or right triangle.

The identity you provided, cot²(x) - tan²(x) = csc²(x) - sec²(x), is a trigonometric identity that can be derived from the Pythagorean identity and the reciprocal identities. Here's one way to prove it:

Start with the Pythagorean identity:

sin²(x) + cos²(x) = 1

Divide both sides by sin²(x):

1 + cos²(x)/sin²(x) = 1/sin²(x)

Recall that cot(x) = cos(x)/sin(x) and tan(x) = sin(x)/cos(x):

1 + cot²(x) = csc²(x)

Subtracting sec²(x) from both sides:

cot²(x) - tan²(x) = csc²(x) - sec²(x)

Therefore, cot²(x) - tan²(x) = csc²(x) - sec²(x) is a valid trigonometric identity.

The length of LG in the plane is

To find the distance between two points in a 2D plane, we can use the distance formula:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

Using this formula, we can find the distance between L(4,4) and G(9,9):

distance = √((9 - 4)^2 + (9 - 4)^2)

= √(5^2 + 5^2)

= √50

= 5√2

The probability that the science teacher trips over the cords for the first time during the 4th period of the day is 0.0279.

A discrete probability distribution has countable alternative values for the random variable and a stated probability for each one. Since the potential values are 0, 1, or 2, and the probability of each conceivable value can be determined, the probability distribution of the number of heads acquired after two coin flips is an example of a discrete probability distribution.

In contrast, a continuous probability distribution has a continuous range of possible values for the random variable and a probability of zero for any given value.

Given that, the probability of tripping is given as: 0.35.

Now, the probability of tripping on the 4th period is given by:

[tex]P(X=k) = (1-p)^{(k-1)} * p[/tex]

Now, for k = 4 and p = 0.35 we have:

[tex]P(X=4) = (1-0.35)^{(4-1)} * 0.35[/tex]

To show that the angle bisector of an equilateral triangle is perpendicular to the base​, we can assume an equilateral triangle with sides ABC. Next, we can get an angle bisector in the middle represented by BD which becomes perpendicular to the base BC.  

After getting the angle bisector, we would see that the line segment BD, divides angle BAC into two equal angles, each measuring 30 degrees. Now, we can draw a perpendicular line from point D to the base BC.

We could also draw a line E, which is the perpendicular line that intersects the base BC. We want to show that BD is perpendicular to BC, which means we need to show that angle BDE is a right angle.

Since the sum of angles BDA and ADE is 90 degrees (they form a right angle), and the sum of angles BAD, ABD, and BDA is 180 degrees, it follows that angle BDE must be a right angle.

Therefore, we have shown that the angle bisector of an equilateral triangle is perpendicular to the base.

Since there are only yellow and green balls in the tub, there is no possibility of picking a red ball. Therefore, the probability of picking a red ball is zero.

(i) The probability of picking a yellow ball can be calculated by dividing the number of yellow balls by the total number of balls. In this case, there are two yellow balls and three green balls, so the total number of balls is 2 + 3 = 5. The probability of picking a yellow ball is 2/5 or 0.4, which is 40%.

(ii) Similarly, the probability of picking a green ball can be calculated by dividing the number of green balls by the total number of balls. In this case, there are three green balls and five total balls. Therefore, the probability of picking a green ball is 3/5 or 0.6, which is 60%.

(iii) As mentioned earlier, there are no red balls in the tub. Hence, the probability of picking a red ball is 0.

The distance from home to second base is approximately 84.85 feet in a slow pitch softball diamond that is 60 feet on each side.

Step-by-step explanation:

In a softball diamond that is 60 feet on each side, the distance from home to second base is approximately 84.85 feet. This is based on the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the distance from home to second base forms the hypotenuse of a right triangle with legs that are each 60 / sqrt(2) feet long. Using the Pythagorean theorem, we can calculate that the distance from home to second base is approximately 84.85 feet.

Thus, the length of chord BD of the given circle is found to be 8.5 units.

A chord is indeed a straight line that connects two points on a circle's circumference. Because it connects to points on the circle's perimeter, the diameter is thought to be the chord with the longest length.
