-17.
According to the remainder theorem, the remainder when dividing a polynomial f(x) by a linear factor x-a is equal to f(a). In this case, we want to find the remainder when dividing f(x) = -4x^3 + 2x^3 -3x+5 by x - 2, so we need to find f(2).
f(2) = -4(2)^3 + 2(2)^3 -3(2) + 5
f(2) = -4(8) + 2(8) -6 + 5
f(2) = -32 + 16 -6 + 5
f(2) = -17
Therefore, the remainder when dividing f(x) = -4x^3 + 2x^3 -3x+5 by x - 2 is -17.

Thank in the shape of a cylinder that contains 54,000 gallons of water in the tank is over 60% food how many gallons of water can the tank hold
The tank can hold up to average 90,000 gallons of water, since it is already filled with 54,000 gallons and 60% of that is food.
Volume = πr2h
= 3.14 x (15 feet)2 x 18 feet
= 15,444.4 cubic feet
15,444.4 cubic feet x 7.48 gallons/cubic feet = 115,511.17 gallons
115,511.17 gallons - 54,000 gallons = 61,511.17 gallons
61,511.17 gallons + 54,000 gallons = 115,511.17 gallons
115,511.17 gallons is the total capacity of the tank.
The tank is able to hold up to 90,000 gallons of water, since it already contains 54,000 gallons and 60% of that is food. This means that the tank can still hold up to 36,000 gallons of water, giving it a total capacity of 90,000 gallons. This is possible because the tank is in the shape of a cylinder, which means that the volume of the tank is determined by the formula V = πr2h, where V is the volume, r is the radius, and h is the height. This means that the tank can be adjusted accordingly to increase or decrease the amount of water it can hold. In this case, the tank is able to hold up to 90,000 gallons of water because the capacity of the tank is determined by the size of its radius and height, and can be adjusted accordingly to increase or decrease the amount of water it can hold.

Find the probability that a randomly selected wafer is (a) produced by machine A and not defective (b) defective given that it is produced by machine B (c) defective (d) not defective
2. At Sam's tune-up and brake repair shop, the manager found that a car will require a tune-up with a probability of 0.6, a brake job with a probability of 0.02.

b) what is the probability that a car requires a tune-up but not a brake job?
c) what is the probability that a car requires neither types of repair?
d) are the events "car requires a tune-up" and "car requires a brake job" independent and mutually exclusive?
1. (a) The probability that a randomly selected wafer is produced by machine A and not defective is 0.665 or 66.5%.
(b) The probability that a wafer is defective given that it is produced by machine B is 0.06 or 6%.

(c) The probability that a car requires neither types of repair is 0.392 or 39.2%.
(d) The events "car requires a tune-up" and "car requires a brake job" are independent because the probability of one event occurring does not affect the probability of the other event occurring. They are not mutually exclusive because a car can require both a tune-up and a brake job at the same time.
We can find the probability using this calculation:
The probability that a randomly selected wafer is produced by machine A and not defective is 0.7 x 0.95 = 0.665 or 66.5%.
The probability that a wafer is defective is (0.7 x 0.05) + (0.3 x 0.06) = 0.035 + 0.018 = 0.053 or 5.3%.
The probability that a wafer is not defective is 1 - 0.053 = 0.947 or 94.7%.
The probability that a car requires either a tune-up or a brake job is 0.6 + 0.02 - (0.6 x 0.02) = 0.608 or 60.8%.
(b) The probability that a car requires a tune-up but not a brake job is 0.6 x (1 - 0.02) = 0.588 or 58.8%.

The sum of two consecutive integers is 85. Find the integers.
(Enter your answers as a comma-separated list.)
The sum of two consecutive integers 42 and 43 is 85.
The sum of two consecutive integers is 85. This means that we need to find two integers that are next to each other on the number line and add up to 85. We can write this as an equation:
x + (x + 1) = 85
Simplifying the equation gives us:
2x + 1 = 85
Subtracting 1 from both sides gives us:
2x = 84
Dividing both sides by 2 gives us:
x = 42
This means that the first integer is 42. Since the two integers are consecutive, the second integer is 42 + 1 = 43. Therefore, the two integers are 42 and 43.

2. Consider a set of vectors of the form (a, 3a, a + b). Determine whether the set is a subspace of R3. If the set is a subspace, give a basis and its dimension. (8 marks total)
The set of vectors of the form (a, 3a, a + b) is not a subspace of R3.
To be a subspace of R3, a set must satisfy the following conditions:
1. The set must be closed under addition.
2. The set must be closed under scalar multiplication.
3. The set must contain the zero vector.
Let's check if the set satisfies these conditions:
1. Closed under addition:
Let u = (a, 3a, a + b) and v = (c, 3c, c + d) be two vectors in the set. The sum of these vectors is u + v = (a + c, 3a + 3c, a + b + c + d). This vector is not in the set because the third component is not of the form a + b. Therefore, the set is not closed under addition.
2. Closed under scalar multiplication:
Let u = (a, 3a, a + b) be a vector in the set and k be a scalar. The scalar multiplication of u and k is ku = (ka, 3ka, ka + kb). This vector is not in the set because the third component is not of the form a + b. Therefore, the set is not closed under scalar multiplication.
3. Contains the zero vector:
The zero vector in R3 is (0, 0, 0). This vector is not in the set because the third component is not of the form a + b. Therefore, the set does not contain the zero vector.
Since the set does not satisfy the conditions to be a subspace of R3, it is not a subspace. Therefore, there is no basis or dimension for this set.

The requried distance formula to calculate the distance between points (x₁, y₁) and (x₂, y₂) is d = √((x₂ - x₁)² + (y₂ - y₁)²)
What is Distance?Distance is defined as the length of measure between two points on the coordinate plane.
Here,
The formula to calculate the distance between two points in a two-dimensional Cartesian coordinate system is:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
Where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points, and sqrt represents the square root function.
This formula is derived from the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the two points represent the endpoints of the hypotenuse, and the distance between them is the length of the hypotenuse. Therefore, we can use the Pythagorean theorem to calculate the distance between the two points.

1

We predict that Ed should draw about 1 blue marble out of the 4 draws. The closest option is 1.
What is probability?
Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.
There are 4 colors of marbles, each with 8 marbles in the bag, so the probability of drawing a blue marble on any given draw is:
P(blue) = 8/32 = 1/4
Since Ed is drawing 4 marbles with replacement, the probability of drawing a blue marble on each individual draw is the same:
P(blue) = 1/4
The probability of drawing a blue marble exactly k times out of 4 draws can be calculated using the binomial probability formula:
P(k blue out of 4) [tex]= (4 choose k) * (1/4)^k * (3/4)^{(4-k)[/tex]
where (4 choose k) is the binomial coefficient, which gives the number of ways to choose k blue marbles out of 4 draws.
E(number of blue) = Σ(k * P(k blue out of 4)), summed over all possible values of k from 0 to 4.
This calculation can be done directly or by using the formula:
E(number of blue) = n * P(blue)
where n is the total number of draws (4 in this case) and P(blue) is the probability of drawing a blue marble on each draw.
Using this formula, we get:
E(number of blue) = 4 * (1/4) = 1
Therefore, we predict that Ed should draw about 1 blue marble out of the 4 draws. The closest option is 1.

For example, the greatest common factor of the trinomial 3x^3 - 6x^2 - 9x is 3x, so the polynomial is equal to 3x times the trinomial x^2 - 2x -3, or 3x*(x^2 - 2x - 3).
Find the missing lengths. Give your answers in both simplest radical form and as approximations correct to two decimal places.
Create drawings as needed.
Given: ΔABC with m∠A = m∠B = 45° and BC = 6
Find: AC and AB
The missing lengths are AC = 3√2 ≈ 4.23 and AB = 3√2 ≈ 4.23.
To find the missing lengths of ΔABC, we can use the properties of a 45-45-90 triangle. A 45-45-90 triangle is a special type of right triangle in which the two legs are congruent and the angles are 45°, 45°, and 90°. The ratio of the sides in a 45-45-90 triangle is 1:1:√2, where the hypotenuse is √2 times the length of each leg.
Since we are given that BC = 6 and ∠A and ∠B are both 45°, we can conclude that ΔABC is a 45-45-90 triangle. Therefore, the lengths of AC and AB are both equal to the length of BC, which is 6.
AC = 6
AB = 6
To find the lengths in simplest radical form, we can multiply the lengths of AC and AB by √2/√2 to get:
AC = 6 * √2/√2 = 6√2/2 = 3√2
AB = 6 * √2/√2 = 6√2/2 = 3√2
To find the approximations correct to two decimal places, we can use a calculator to find the decimal values of 3√2:
AC ≈ 3 * 1.41 = 4.23
AB ≈ 3 * 1.41 = 4.23
Therefore, the missing lengths are AC = 3√2 ≈ 4.23 and AB = 3√2 ≈ 4.23.

Answer:
The volume of a rectangular solid is given by the formula V = LWH, where L is the length, W is the width, and H is the height.
In this case, we have:
W = x + 3
L = x + 2
H = x
So the volume is:
V = (x + 2)(x + 3)(x)
V = x(x + 2)(x + 3)
V = x(x^2 + 5x + 6)
V = x^3 + 5x^2 + 6x
Therefore, the volume of the rectangular solid is given by the polynomial expression x^3 + 5x^2 + 6x.
A triangle has angle measurements of 3°, 35°, and 142°. What kind of triangle is it?
The triangle is an obtuse triangle.
What is a valid triangle?
A valid triangle is a geometric figure with three sides and three angles. To be considered a valid triangle, it must satisfy the following conditions:
1. The sum of the lengths of any two sides must be greater than the length of the third side. This is known as the Triangle Inequality Theorem, and it ensures that the three sides can form a closed figure.
2. The measure of each angle must be less than 180 degrees. This is known as the Angle Sum Theorem, and it ensures that the three angles can fit inside a two-dimensional plane.
The sum of the angles of any triangle is always 180 degrees.
So, if a triangle has angle measurements of 3°, 35°, and 142°, we can add them up to check whether they add up to 180 degrees:
3° + 35° + 142° = 180°
Since the sum of the angles is 180 degrees, the triangle is a valid triangle.
Now, we can classify the triangle based on the measure of its angles. Since the measure of one angle (142°) is greater than 90 degrees, the triangle is an obtuse triangle.
We cannot determine the length of the sides of the triangle based on the angle measures provided. So, we cannot classify the triangle based on the length of its sides.
Therefore, the triangle is an obtuse triangle.

In mathematics, an equation is a statement that two expressions are equal. It contains an equals sign (=) between two expressions, which are usually composed of variables, constants, and mathematical operations.
For example, the equation:
2x + 3 = 7
states that the sum of two times x and three is equal to seven. This equation can be solved to find the value of x that satisfies it.
Equations can be used to model and solve a wide range of problems in mathematics and science, including algebraic, geometric, and physical problems.
Assuming that Jean earns a fixed hourly rate, we can use the equation:
y = kx
where y is the total earnings, x is the number of hours worked, and k is the hourly rate.
For example, if Jean earns $12 per hour, the equation would be:
y = 12x
This means that for each hour worked, Jean earns $12, and the total earnings y increase linearly with the number of hours x worked.

RADICALS AND QUADR Applying the quadrati Jse the quadratic formula to 9x^(2)-3x-1=0 If there is more than one sol
The quadratic formula is used to solve equations of the form ax^(2) + bx + c = 0. The formula is given by:
x = (-b ± √(b^(2) - 4ac))/2a
In this case, the coefficients are a = 9, b = -3, and c = -1. Plugging these values into the formula gives:
x = (-(-3) ± √((-3)^(2) - 4(9)(-1)))/2(9)
Simplifying the expression gives:
x = (3 ± √(9 + 36))/18
x = (3 ± √45)/18
x = (3 ± 3√5)/18
Simplifying further gives:
x = (1 ± √5)/6
So the two solutions to the equation are:
x = (1 + √5)/6 ≈ 0.62
and
x = (1 - √5)/6 ≈ -0.29
Therefore, the two solutions to the equation 9x^(2)-3x-1=0 are x ≈ 0.62 and x ≈ -0.29.

Bill's SUV is 6 feet 4 inches tall. If he puts a 2 -foot 9 -inch box on top of his SUV, what is the total height of the SUV and the box (in feet and inches)?
Answer: The total height of the SUV and the box is 9 feet 1 inch.
Step-by-step explanation:
To solve this problem, we first convert the height of the SUV and the box from feet and inches to inches. The height of the SUV is 6 feet 4 inches, which is equal to 76 inches. The height of the box is 2 feet 9 inches, which is equal to 33 inches. We then add the heights of the SUV and the box to get the total height:
76 inches + 33 inches = 109 inches
To convert this back to feet and inches, we divide by 12 to get 9, with a remainder of 1. Therefore, the total height of the SUV and the box is 9 feet 1 inch.

What is the variable if
the trinomial a^2+7a+6 and the binomial a+1 have the same value?
The variable that satisfies the condition that the trinomial a^2 + 7a + 6 and the binomial a + 1 have the same value is a = -5 or a = -1.
How is a variable determined?Setting the trinomial and binomial equal to one another and then solving for the variable will help us identify the variable that satisfies the stated criteria. Which is:
a^2 + 7a + 6 = a + 1
By putting all the terms to one side and grouping like terms, we may make this equation simpler:
a^2 + 6a + 5 = 0
The quadratic expression on the left-hand side can now be factored:
(a + 5)(a + 1) = 0
To make each factor equal to zero, we can use the zero product property:
a + 5 = 0 or a + 1 = 0
In each equation, we can solve for a to obtain:
a = -5 or a = -1

When an airplane accelerates down a runway at 3.20 m/s2 to 5.41 m/s2 for 28 s until is finally lifts off the ground calculate its acceleration before it takes off.
Answer:
-87.786
Step-by-step explanation:
Given:
Acceleration 1 = 3.20 m/s²
Acceleration 2 = 5.41 m/s²
Time = 28 s
To find: Acceleration before takeoff
Initial velocity = Average acceleration x time + 0.5 x acceleration 1 x time²
Initial velocity = 3.20 m/s² x 28 s + 0.5 x 3.20 m/s² x (28 s)²
Initial velocity = 2460.8 m
Acceleration before takeoff = (0 m/s - 2460.8 m/s) / 28 s
Acceleration before takeoff = -87.886 m/s²
Therefore, the acceleration before takeoff is -87.886 m/s².
