At which root does the graph of f x x 5 3 * x 2 2 touch the X axis?
The root of the graph of f(x) =(x - 5)3(x + 2)2 touches the x-axis at -2,5
(x - 5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.
(x + 2)^2 has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.
Given: Function f(x) is (x - 5)3(x + 2)2
If a curve touches the x-axis then f(x) = 0
⇒ (x - 5)3(x + 2)2 = 0.
But if ab = 0 ⇒ either a = 0 or b = 0 or both zero.
⇒ (x - 5)3 = 0 and (x + 2)2 = 0
⇒ (x - 5) = 0 and x + 2 = 0
⇒ x = 5 and x = - 2.

1. Find the volume of the solid obtained by rotating the
triangle (2,5)(2,3)(1,2) about the vertical axis:
2. Find the centroid of the region bounded by the parabolas: y =
x2 − 4, y = 0.75x 2 − 3.
To find the volume of the solid obtained by rotating the triangle (2,5), (2,3), (1,2) about the vertical axis, we can use the method of cylindrical shells.
The height of each cylindrical shell will be the difference in y-coordinates between the upper and lower points of the triangle, which is (5-2) = 3 units.The radius of each cylindrical shell will be the x-coordinate of the triangle point, which varies from x = 1 to x = 2.Therefore, the volume of the solid can be calculated as:\(V = ∫[1,2] 2πx(3) dx\)
\(V = 6π ∫[1,2] x dx\)
\(V = 6π [x^2/2] [1,2]\)
\(V = 6π [(2^2/2) - (1^2/2)]\)
\(V = 6π [2 - 0.5]\)
V = 6π (1.5)
V ≈ 9π
The volume of the solid obtained by rotating the triangle about the vertical axis is approximately 9π units.

find the value(s) of c guaranteed by the mean value theorem for integrals for the function over the given interval. (round your answer to four decimal places. enter your answers as a comma-separated list.) f(x)= 3Vx, [4,9]
The value of c guaranteed by the Mean Value Theorem for Integrals for the function f(x) = 3√x over the interval [4, 9] is approximately 6.1084.
By the Mean Value Theorem for Integrals, there exists at least one value c in the interval [4, 9] such that:
f(c) = (1 / (9 - 4)) * ∫[4,9] f(x) dx
where f(x) = 3√x.
To find the value(s) of c, we first need to evaluate the integral:
∫[4,9] 3√x dx = 2[9^(3/2) - 4^(3/2)]
Using a calculator, we get:
∫[4,9] 3√x dx ≈ 24.0416
For the function f(x) = 3√x on the interval [4,9], we have:
f(a) = f(4) = 3√4 = 6
f(b) = f(9) = 3√9 = 9
Substituting this and f(x) into the equation above, we get:
3√c = (1/5) * 24.0416
Therefore, by the mean value theorem for integrals, there exists at least one value c in (4,9) such that:
f(c) = (1/(9-4)) * ∫[4,9] f(x) dx
= (1/5) * 19.3070
= 3.8614
Simplifying, we get:
c = (24.0416 / 15) ≈ 6.1084

Suppose that the joint probability density of two random variables X1 and X2 is given by F(x1,X2) = {6e^-2x1-3x2 for x1 > 0 and x2 > 0, otherwise.
Find the probability P(I2).
Solution: The joint probability density of two random variables X1 and X2 is given by F(x1, x2) = {6e^(−2x1 − 3x2) for x1 > 0 and x2 > 0, otherwise. Find the probability P(I2).It is known that, for any joint probability density function f(x, y) and any real number a,b,c, and d such that a ≤ b and c ≤ d, we have: P(a ≤ X ≤ b, c ≤ Y ≤ d) = ∫(c to d) ∫(a to b) f(x,y)dxdy.
We use this formula to calculate the required probability. We have:I2 = {X2 > 2X1}. Hence, we want to find the probability that X2 > 2X1. This probability can be written as: P(I2) = P(X2 > 2X1) = ∫(0 to ∞) ∫(2x1 to ∞) f(x1,x2)dx2dx1= ∫(0 to ∞) ∫(2x1 to ∞) 6e^(−2x1 − 3x2) dx2dx1= 6 ∫(0 to ∞) e^(−2x1) ∫(2x1 to ∞) e^(−3x2) dx2dx1Now, let's solve the inner integral first. We get:∫(2x1 to ∞) e^(−3x2) dx2= (-1/3) e^(−3x2)|2x1 to ∞= (-1/3) e^(−6x1)Now we substitute this value of the integral back into the outer integral. We get: P(I2) = 6 ∫(0 to ∞) e^(−2x1) (-1/3) e^(−6x1) dx1= (-2) ∫(0 to ∞) e^(−8x1) dx1= (-2) (1/8)= -1/4. Hence, the required probability P(I2) is equal to -1/4.

if p(x) is divided by (x 1) three times and has remainder of 1 at the end, then -1 is a double root.
If the polynomial p(x) is divided by (x-1) three times and has a remainder of 1 at the end, then -1 is a double root of p(x). This means that (x+1) is a factor of p(x) raised to the power of 2.
When a polynomial is divided by (x-1), the remainder represents the value of the polynomial at x=1. Since the remainder is 1, it implies that p(1) = 1. Dividing p(x) by (x-1) three times indicates that the polynomial has been factored by (x-1) three times. Consequently, the polynomial can be written as p(x) = (x-1)^3 * q(x) + 1, where q(x) is the quotient obtained after dividing p(x) by (x-1) three times. Since the remainder is 1, it means that when x=1, p(x) leaves a remainder of 1.
Thus, (1-1)^3 * q(1) + 1 = 1, which simplifies to q(1) = 0. This implies that (x-1) is a factor of q(x), meaning that q(x) can be written as q(x) = (x-1) * r(x), where r(x) is another polynomial.
Substituting this into the earlier expression for p(x), we get p(x) = (x-1)^3 * (x-1) * r(x) + 1. Simplifying further, p(x) = (x-1)^4 * r(x) + 1. Now, we can see that p(x) is divisible by (x+1) since (x+1) is a factor of (x-1)^4, and the remainder is 1. Therefore, -1 is a double root of p(x) because (x+1) appears twice in the factored form of p(x).

Use the rational zeros theorem to find all the real zeros of the polynomial function. use the zeros to factor f over the real numbers. f(x)=x^3-5x^2-61x-55???
The polynomial function f(x) = x³ - 5x² - 61x - 55 has the following
Real zeros: x = -5, x = -1, and x = 11.
To find the rational zeros of a polynomial, we use the rational zeros theorem. We look at the factors of the leading coefficient and the factors of the constant coefficient.
The states that if a polynomial function is defined as P(x) = anxn + an-1xn-1 + ... + a1x + a0 with integers, then each rational zero of the polynomial can be expressed in the form p/q where p is a factor of a0 and q is a factor of an.
For example, if P(x) = 2x³ - 5x² + 3x + 6 then p can be any factor of 6 and q can be any factor of 2.
The factors of the leading coefficient, 1, and the factors of the constant coefficient, -55, are: ±1, ±5, ±11, ±55. So the possible rational zeros are: ±1, ±5, ±11, ±55, ±1/1, ±5/1, ±11/1, ±55/1, ±1/1, ±5/1, ±11/1, ±55/1.
Simplifying the results, we have that the potential rational zeros are: ±1, ±5, ±11, ±55, ±1, ±5, ±11, and ±55.
By testing each possible rational zero, we find that x = -5, x = -1, and x = 11 are the real zeros of f(x).
Hence, using synthetic division, we get:
(x + 5)(x + 1)(x - 11) = x³ - 5x² - 61x - 55
Thus, the function can be factored over the real numbers as
f(x) = (x + 5)(x + 1)(x - 11).

A recipe calls for mixing 8/5 cups of blueberries and 7/5
cups of strawberries. The mix is divided equally among 18 items. What fraction of a cup is used for each item?
3 cups of fruit mix is divided equally among 18 items.
Each item will contain 1/6 cup of fruit mix.
How to find out what fraction of a cup is used for each item ?First we need to divide the total amount of fruit mix by the number of items.
The total amount of fruit mix is :
8/5 cups of blueberries + 7/5 cups of strawberries
= (8/5 + 7/5) cups
= 15/5 cups
= 3 cups
So, 3 cups of fruit mix is divided equally among 18 items.
To find the fraction of a cup used for each item, we need to divide 3 cups by 18:
