al numbers that could be zeros of the polynomial accordir P(v)=14v^(5)+6v^(4)+5v^(3)-4v^(2)+2v

The exact form of the zeros of the polynomial function c(x)=3x^(4)-2x^(3)-39x^(2)-10x+24 are x=-4, x=-3/2, x=2, and x=1.

To find all the zeros of the polynomial function c(x)=3x^(4)-2x^(3)-39x^(2)-10x+24, we need to find the values of x that make c(x)=0. One way to do this is by using the Rational Root Theorem, which states that if a polynomial has rational zeros, then they must be in the form of p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

The factors of the constant term, 24, are ±1, ±2, ±3, ±4, ±6, ±8, ±12, and ±24. The factors of the leading coefficient, 3, are ±1 and ±3. Therefore, the possible rational zeros are ±1, ±2, ±3, ±4, ±6, ±8, ±12, and ±24.

Using synthetic division, we can test these possible zeros to see if they are actually zeros of the polynomial. After testing, we find that the zeros are -4, -3/2, 2, and 1.

So, the exact form of the zeros of the polynomial function c(x)=3x^(4)-2x^(3)-39x^(2)-10x+24 are x=-4, x=-3/2, x=2, and x=1.

Answer:

x= 3 or x = -3

Step-by-step explanation:

We can see here that the two values that x can have if 5x² + 41 = 86 is -3 and +3.

To find the values of x that satisfy the equation 5x² + 41 = 86, we can start by isolating the term with the variable on one side of the equation. Here's the step-by-step solution:

Subtract 41 from both sides of the equation:

5x² + 41 - 41 = 86 - 41

5x² = 45

Divide both sides of the equation by 5:

(5x²) / 5 = 45 / 5

x² = 9

Take the square root of both sides of the equation:

√(x²) = √9

x = ±3

Therefore, the equation 5x² + 41 = 86 has two solutions: x = 3 and x = -3.

Answer:

The formula for the length of an arc of a circle is given by:

length of arc = (central angle/360) x 2πr

where r is the radius of the circle and the central angle is measured in degrees.

In this problem, we know the length of arc RV is 3π/2 units and the radius of circle M is 6 units. Therefore, we can solve for the central angle using the formula above:

3π/2 = (central angle/360) x 2π(6)

3π/2 = (central angle/180) x π x 6

3/2 = (central angle/180) x 6

central angle = (3/2) x (180/6) = 45 degrees

So the approximate measure of angle RMV is 45 degrees, which corresponds to option B.

To estimate the average height of black spruce trees in a 1,000 ha plot with 99% confidence that the estimate is within 0.5 m, you need a sample size of at least 19. This is based on the standard deviation of tree heights in a nearby location of 1.10 m as determined in a study conducted last year.

To estimate the average height of black spruce trees in a 1,000 ha plot with 99% confidence that the estimate is within 0.5 m, we can use the formula for sample size calculation:

n = (z² × σ²) / E²

Where:

n = sample size

z = z-score for the desired confidence level (99% confidence level corresponds to a z-score of 2.576)

σ = standard deviation (1.10 m)

E = margin of error (0.5 m)

Plugging in the values into the formula, we get:

n = (2.576² × 1.10²) / 0.5²n = 18.15.

Therefore, the sample size must be at least 19 black spruce trees to have 99% confidence that the estimate is within 0.5 m.

Answer:

The lateral area of the prism is 190 square inches and the total surface area is 358 square inches.

Step-by-step explanation:

To find the lateral area and total surface area of a rectangular prism, we need to use the following formulas:

Lateral Area = perimeter of the base x height

Total Surface Area = 2 x base area + lateral area

Where the base area is simply the product of the length and width of the rectangular prism.

Let's apply these formulas to the rectangular prism with dimensions 12in x 7in x 5in:

Lateral Area:

To find the perimeter of the base, we add up the lengths of all four sides of the rectangle:

Perimeter of the base = 2(length + width) = 2(12in + 7in) = 2(19in) = 38in

Now, we multiply the perimeter of the base by the height of the prism:

Lateral Area = 38in x 5in = 190in^2

Therefore, the lateral area of the rectangular prism is 190 square inches.

Total Surface Area:

To find the base area, we simply multiply the length and width of the rectangular prism:

Base Area = length x width = 12in x 7in = 84in^2

Now, we can use the formula for total surface area:

Total Surface Area = 2 x base area + lateral area

Total Surface Area = 2(84in^2) + 190in^2

Total Surface Area = 168in^2 + 190in^2

Total Surface Area = 358in^2

Therefore, the total surface area of the rectangular prism is 358 square inches.

So the lateral area of the prism is 190 square inches and the total surface area is 358 square inches.

The average speed of the boat relative to the water is approximately 17.08 mph.

The average speed of the boat relative to the water can be found by using the formula for distance, speed, and time:

distance = speed × time

We can use this formula to set up two equations, one for the downstream trip and one for the upstream trip:

38 = (s + 6) × t₁

38 = (s - 6) × t₂

We can then use the given information about the total time of the trip to find the values of t₁ and t₂:

4.75 = t₁ + t₂

We can rearrange the first two equations to solve for t₁ and t₂ in terms of s:

t1 = 38/(s + 6)

t2 = 38/(s - 6)

Substituting these values into the third equation and simplifying gives us:

4.75 = 38/(s + 6) + 38/(s - 6)

4.75s² - 57s - 114 = 0

Using the quadratic formula, we can solve for s:

s = (57 ± √(57₂ - 4(4.75)(-114)))/(2(4.75))

s ≈ 17.08 or s ≈ -3.01

Answer: The function to express the total amount of money Martin will make as a function of the number of calls he makes is:

Total Money = (Number of hours worked x Base pay per hour) + (Bonus pay per hour x Number of bonus calls)

Where:

Number of hours worked = 4

Base pay per hour = $75 / 4 = $18.75 (since he works for 4 hours every day and receives $75)

Bonus pay per hour = ($5.50 x (Number of bonus calls)) / 4 (since he works for 4 hours every day and receives a bonus of $5.50 per call over 35 in one hour, which is equivalent to $5.50 / 4 per call)

Number of bonus calls = (Total calls - (Number of hours worked x Baseline calls per hour))

Using this formula, we can calculate how much money Martin will make for the day if he makes a total of 45 calls every hour:

Number of bonus calls = (45 - (4 x 35)) = 5

Bonus pay per hour = ($5.50 x 5) / 4 = $6.875

Total Money = (4 x $18.75) + (4 x $6.875) = $75 + $27.50 = $102.50

Therefore, if Martin makes a total of 45 calls every hour, he will make $102.50 for the day.

The height of the cone is approximately 28.867 units and the radius is approximately 21.65 units.

Let's denote the height of the cone as "h" and the radius as "r".

From the problem statement, we know that:

r = (3/4)h ...(1) (given)

The surface area of the cone is given as 3750 square units. The formula for the surface area of a cone is:

Surface Area of Cone = πr(r + l),

where "l" is the slant height of the cone. Since the slant height is not given in the problem, we need to express "l" in terms of "r" and "h" using the Pythagorean theorem:

l² = r² + h²

l² = (3/4)² h² + h²

l² = (9/16)h² + h²

l² = (25/16)h²

l = (5/4)h

Substituting this expression for "l" and the expression for "r" from equation (1) into the surface area formula, we get:

3750 = πr(r + l)

3750 = π[(3/4)h] [(3/4)h + (5/4)h]

3750 = π (9/16 + 15/16) h²

3750 = π (24/16) h²

3750 = (3/2) π h²

The polynomial function P(x) with a quadratic function zero of 3-4i and an additional zero is P(x) = (x2 - 6x + 25)(x - additional zero).

A polynomial function, P(x), is a function that can be written in the form P(x) = anxn + an-1xn-1 + ... + a1x + a0, where n is a non-negative integer and an, an-1, ..., a1, a0 are real numbers. A quadratic function is a polynomial function of degree 2, which means it can be written in the form P(x) = ax2 + bx + c.

If a polynomial function has a zero of 3-4i, then it must also have a zero of 3+4i, since complex zeros always come in conjugate pairs. This means that the polynomial function must have factors of (x - (3-4i)) and (x - (3+4i)). Multiplying these two factors together gives us (x - 3 + 4i)(x - 3 - 4i) = x2 - 6x + 25.

If the polynomial function also has an additional zero, then it must have a factor of (x - additional zero). Multiplying this factor with the previous one gives us P(x) = (x2 - 6x + 25)(x - additional zero).

The total surface area of the hollow hemisphere is 1736.4 cm²

The total surface area of a large round bowl (hollow hemisphere) can be calculated by finding the surface area of the outer hemisphere and the surface area of the inner hemisphere and area of the ring and adding them together.

The formula for the surface area of a hemisphere is 2πr^2, where r is the radius of the hemisphere.

The outer radius of the bowl is 12 cm, so the surface area of the outer hemisphere is:

Surface area of outer hemisphere = 2π(12)^2 = 2π(144) = 288π

The inner radius of the bowl is the outer radius minus the thickness, which is 12 - 1 = 11 cm. So the surface area of the inner hemisphere is:

Surface area of inner hemisphere = 2π(11)^2 = 2π(121) = 242π

area of the concentric circle joining the outer surface and inner surface is π(12²-11²)= 23π

The total surface area of the bowl is the sum of the surface area of the outer hemisphere and the surface area of the inner hemisphere:

Total surface area = 288π + 242π + 23π = 553π

So the total surface area of the bowl is 530π cm^2.

then we can use the approximation π ≈ 3.14 to find the total surface area:

Total surface area ≈ 553*(3.14) ≈ 1736.4 cm^2

So the total surface area of the bowl is approximately 1736.4 cm^2.
