If the base diameter of the sawdust pile is 35 feet when the height is 30 feet, then when it is 40 feet high, the diameter will be 46.7 feet, while the volume will be 68,545.37 feet³.

The volume refers to the capacity of a three-dimensional object.

The formula for volume with diameter and height is V = πd²h/4.

Base diameter of the sawdust pile = 35 feet

Height = 30 feet

Base diameter of the sawdust pile when the height is 40 feet = 46.7 feet

(35/30 x 40)

Given height = 40 feet

Computed base diameter = 46.7 feet

Volume = πd²h/4

= 22/7 x 46.7² x 40/4

= 3.143 x 2,180.89 x 10

= 68,545.37 feet³

The solution set of f(x) > 0 is x ∈ (-2, 8).

To find the solution set of f(x) > 0, we need to first determine the critical values of x where f(x) changes sign.

Let's start by finding the domain of the function:

x² - 6x - 16 ≠ 0

We can solve for x by using the quadratic formula:

x = [6 ± √(6² + 4(16))]/2 = [6 ± √52]/2 = 3 ± √13

So the domain of f(x) is (-∞, 3 - √13) U (3 + √13, ∞).

Now let's factor the numerator and denominator of f(x):

f(x) = (x + 10)/[(x - 8)(x + 2)]

The critical points occur where the numerator or denominator of f(x) changes sign.

The numerator changes sign at x = -10, and the denominator changes sign at x = -2 and x = 8.

Answer:

Yes.

Step-by-step explanation:

(2, 3) means we'll let x be 2 and y be 3. Let's solve both equations first:

y = -2x + 7

3 = -2(2) + 7

3 = -4 + 7

:. 3 = 3

Okay, so one half is proven. Let's do the other half now.

y = x + 1

3 = 2 + 1

3 = 3

:. (2,3) is a solution to the system of equations.

The null and alternative hypotheses that apply are as follows:

H0: p ≤ 0.54, which claims that the proportion of pupils finishing class with a grade of A, B, or C in this experimental curriculum is no greater than 54%.

H₁: p > 0.54, according to the alternative hypothesis, asserts that the rate of students concluding the course with an A, B, or C grade in its experimental form must be above 54%.

The letter "p" represents the proportion of student grades in the experimental program who reach either A, B, or C levels.

The sketch of the graph of y = 1/f(x) is added as an attachment

To find the function equation, we need to determine the factors of the equation based on the zeros of the function.

Since the zeros of the function are at x = -5, -1, and 4, the factors of the equation will be:

(x + 5), (x + 1), and (x - 4)

Multiplying these factors together gives us:

f(x) = a(x + 5)(x + 1)(x - 4)

To find the value of the constant term a, we can use the fact that the graph passes through the point (0, -4):

-4 = a(0 + 5)(0 + 1)(0 - 4)

-4 = -20a

So, we have

a = 1/5

Therefore, the function equation is:

f(x) = 1/5(x + 5)(x + 1)(x - 4)

For the graph of y = 1/f(x), we have

y = 5/[(x + 5)(x + 1)(x - 4)]

Answer:

D. 263 degrees

Step-by-step explanation:

We know that central angles are congruent to the arcs they encompass or intercept. So, if the minor arc is 97 degrees, and the total measure of a circle's arcs are 360 degrees, then the major arc is 263 degrees.

Therefore, the answer is D.

The monthly payment and total price paid by Antony at interest rate of 6.8% for vehicle is $362.59 and $21204.4 respectively.

Cost price of the car Antony decided to purchase = $19,000

Down payment =  20% of purchase value

Interest rate of amount to be finance = 6.8%

Time period of finance amount = 4 years

Down payment = 0.2 × $19,000

                         = $3,800

Amount that Anthony needs to finance,

Amount to finance = $19,000 - $3,800

                               = $15,200

The monthly payment , use the formula for the monthly payment on a loan,

M = P × r × (1 + r)ⁿ / ((1 + r)ⁿ - 1)

where M is the monthly payment,

P is the principal the amount to finance

r is the monthly interest rate

n is the total number of payments which is the number of years multiplied by 12

The monthly interest rate is 6.8% / 12 = 0.00567,

and the total number of payments is 4 × 12 = 48.

Substituting these values into the formula, we get,

⇒M = $15,200 × 0.00567 × (1 + 0.00567)⁴⁸ / ((1 + 0.00567)⁴⁸ - 1)

⇒M = $15,200 × 0.00567 × 1.3118 / (1.3118 -1)

⇒M = $15,200 × 0.00567 × 1.3118 / 0.3118

⇒M = 113.056 / 0.3118

⇒M ≈ $362.59

Anthony's monthly payment will be about $362.59

Total price that Anthony paid for his vehicle,

add up the down payment and the total amount of payments over the 4-year period.

Total price = $3,800 + ( $362.59 × 48)

                  = $21204.4

Therefore, the monthly payment and the total price at interest rate of 6.8% that Anthony paid for vehicle is $362.59 and $21204.4 respectively.

25% percent of the females in Math town have brown eyes. To find the number of females with brown eyes, we need to subtract the number of males with brown eyes from the total number of people with brown eyes

what is percent  ?

A percent is a way of expressing a number as a fraction of 100. The symbol for percent is %, which means "per hundred".

In the given question,

Let's assume that there are 100 people in Math town.

60% of them are males, so there are 60 males and 40 females.

Out of the 60 males, 30% have brown eyes, so there are 18 males with brown eyes.

28% of the entire population have brown eyes, so there are 28 people with brown eyes.

To find the number of females with brown eyes, we need to subtract the number of males with brown eyes from the total number of people with brown eyes:

28 - 18 = 10

So, there are 10 females with brown eyes.

Out of the 40 females in Math town, what percentage have brown eyes?

10 brown-eyed females out of 40 females is:

10/40 = 0.25 or 25%

If two  lines intersect  at an angle of 90˚ or are perpendicular to each other, they form a right angle. A right angle is indicated by the symbol ∟Angle is always 90° or a right angle. The  opposite angle of 90° is the hypotenuse. The hypotenuse is always the longest side. The sum of the remaining two interior angles is  90°.  In a right-angled triangle, the side opposite  the 90-degree angle is called the hypotenuse, indicated by the letter "c". The sides adjacent to a 37 degree angle and a right angle are called "ab" and "bc" respectively.  

Using trigonometry, we  find the length of "ab" as follows:

sin(37) = opposite/hypotenuse = ab/c

ab = sin(37) * c

The expression for the velocity is v(t) = 30m/s

(a) x(t) = 30t

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = 30t, we have:

v(t) = d/dt (30t)

= 30

So the expression for velocity is v(t) = 30 m/s.

(b) x(t) = 7sin(30)

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = 7sin(30), we have:

v(t) = d/dt (7sin(30))

= 7cos(30) * d/dt (30t)

= 3.5cos(30)

So the expression for velocity is v(t) = 3.5cos(30) m/s.

(c) x(t) = ecos(701)

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = ecos(701), we have:

v(t) = d/dt (ecos(701))

= -e sin(701) * d/dt (701t)

Let's use $a for the sharpener's price. We can state that the price of a book is $a + 1.95 because it costs $1.95 more than a sharpening.

We are aware of the $26.10 total cost of 10 sharpeners and 2 books. This can be expressed as an equation:

10a + 2(a + 1.95) = 26.10

If we simplify this equation, we get:
