what is the quotient when -3^3 +5x+14 is divided by x-2? pleas hurry
The quotient is -3x² + 3x + 8.
To find the quotient when [tex]\(-3x^3 + 5x + 14\)[/tex] is divided by x - 2, we can use polynomial long division.
The dividend is [tex]\(-3x^3 + 0x^2 + 5x + 14\)[/tex] (since there is no [tex]\(x^2\)[/tex] term) and the divisor is x - 2.
1. Divide the first term of the dividend by the first term of the divisor: [tex]\(-3x^3 \div x = -3x^2\)[/tex].
2. Multiply the divisor by the result of step 1: [tex]\((-3x^2)(x - 2) = -3x^3 + 6x^2\).[/tex]
3. Subtract the result of step 2 from the dividend: [tex]\((-3x^3 + 0x^2 + 5x + 14) - (-3x^3 + 6x^2) = -6x^2 + 5x + 14\).[/tex]
4. Repeat the process with the new dividend [tex]\(-6x^2 + 5x + 14\)[/tex].
Continuing the division process, we find the quotient:
[tex]\[ \frac{-3x^3 + 5x + 14}{x - 2} = -3x^2 + 3x + 8 \][/tex]
So, the quotient is -3x² + 3x + 8.
what is 1/4 divided by 5?
1/4 divided by 5 results into '0.05'
Given that we need to find 1/4 divided by 5
Thus let the required answer be denoted as "A"
Thus using basic definitions of divisions and fractions we can find out the resultant value
[tex]A=\frac{\frac{1}{4} }{5} \\A=\frac{1}{4*5} \\A=\frac{1}{20}[/tex]
Thus '1/20' is the required answer
Now the resultant value can also be simplified to get a decimal value
[tex]A=\frac{1}{20} \\A=\frac{1}{2*10} \\A=\frac{1}{2} *\frac{1}{10} \\A=0.5*0.1\\A=0.05[/tex]
Thus '0.05' is the final answer

The graph of an absolute value function contains the points (1, 2), (0, 0), and (–1, 2). Shawn thinks the function this graph represents is f(x) = 2|–x|. Brielle thinks the function this graph represents is f(x) = 2|x|. Determine who is correct and explain why.
Answer:
The absolute value parent function is symmetric with respect to the y-axis.
The graphs of f(x) = 2|–x| and f(x) = 2|x| are identical because the absolute value of negative x is a reflection across the y-axis.
If you substitute the three given points into both functions, they produce true statements.

Given the table of candy distribution below. find P(Not blue). the probability of selecting anything but an blue candy at random from a large bag.
Red=0.13 Orange=0.20 Yellow=? Green=0.16 Blue=0.24 Brown=0.13
Since, probability of selecting a blue candy and anything but a blue candy are mutually exclusive events, the probability of selecting anything but an blue candy at random from a large bag = P(Not blue) = 0.76
What are mutually exclusive events?In logic and probability theory, two events are mutually exclusive or disjoint if they cannot both occur at the same time.
P(Blue) + P(Not blue) = 1 (mutually exclusive events)
0.24 + P(Not blue) = 1
P(Not blue) = 1 - 0.24 = 0.76

Name an angle adjacent to ∠DGE
Choices:
∠FGI
∠EGH
∠HGJ
Answer:
The answer is ∠EGH.
Step-by-step explanation:
In order to determine the correct option, we have to know about adjacent angle.
Two angles are adjacent when they have a common side and vertex (corner point). So in this case, the adjacent angle must have GE or DG common side and the G vertex.
According to the options, the adjacent angle to ∠DGE is:
∠EGH
The other options are not adjacent angles because they do not have a common side.
Finally the correct option is ∠EGH.

What will your answer be if you round 16.2 to the nearest whole number
Final answer:
To round 16.2 to the nearest whole number, check the first digit after the decimal. It's less than 5, so round down to 16.
Explanation:
When rounding 16.2 to the nearest whole number, you need to look at the first digit after the decimal point, which is 2 in this case. If that digit is 5 or greater, you would round up. If it is less than 5, you round down. Since 2 is less than 5, we round down, so the whole number that 16.2 gets rounded to is 16.

(1, 2), (1, 1), (2, 0), (0, 4), (2, 1)
(2, 0), (2, 1), (3, 2), (4, 1), (1, 3)
The rate of change in miles per gallon for a car trip represents the number of miles the car can travel per gallon of gasoline used. The ordered pairs (0, 2), (1, 2), (2, 3), (1, 4), (3, 1) accurately correspond with the values provided in the given table.
Explanation:In the given situation, the rate of change of a graph showing the miles per gallon of gasoline a car uses on a trip would represent the number of miles traveled for every one gallon of gas used. This is because the rate of change in this context quantifies how much distance can be covered (in miles) using one unit of gasoline (in gallon). For instance, if the rate of change is 30, it indicates that the car can travel 30 miles using just one gallon of gasoline.
For the second part of your question, matching the ordered pairs with the table, the correct match would be (0, 2), (1, 2), (2, 3), (1, 4), (3, 1). This set of pairs corresponds accurately to the values given in your table for x and y. To understand this, you can match each x value with its corresponding y value in the table. For example, when x is 0, y is 2 - and this gives you the ordered pair (0, 2).

A ball is thrown at a 30 degree angle above the horizontal with a speed of 10 ft/s. After 0.50s the horizontal component of it's velocity will be ____? ...?
The horizontal component of the velocity of a ball thrown at a 30 degree angle above the horizontal with an initial speed of 10 ft/s will remain approximately 8.66 ft/s after 0.50s, assuming no air resistance.
Explanation:A ball is thrown at a 30 degree angle above the horizontal with a speed of 10 ft/s. After 0.50s the horizontal component of its velocity will remain the same, assuming no air resistance, because horizontal velocity in projectile motion is constant if air resistance is ignored. The vertical component will change due to gravity, but that does not affect the horizontal component.
To find the horizontal component of the velocity, we can use the cosine of the launch angle:
Horizontal velocity (v_x) = initial speed * cos(launch angle)
So, v_x = 10 ft/s * cos(30 degrees)
= 10 ft/s * (√3/2)
≈ 8.66 ft/s
As there is no horizontal acceleration in ideal projectile motion, after 0.50s, the horizontal component of the ball's velocity will still be approximately 8.66 ft/s.
What is the average rate of change of f(x), represented by the graph, over the interval [-1, 1]
The average rate of change of f(x) over the interval [-1, 1] is 5.
To find the average rate of change of f(x) over the interval [-1, 1], we use the formula:
[tex]\[ \text{Average Rate of Change} = \frac{\text{Change in } f(x)}{\text{Change in } x} \][/tex]
First, we find the change in f(x) over the interval [-1, 1]. The function values at x = -1 and x = 1 are f(-1) = -5 and f(1) = 5 respectively. So, the change in f(x) is 5 - (-5) = 10.
Next, we find the change in x over the same interval. The interval [-1, 1] has a width of 1 - (-1) = 2.
Finally, we divide the change in f(x) by the change in x to get the average rate of change:
[tex]\[ \text{Average Rate of Change} = \frac{10}{2} = 5 \][/tex]
So, the average rate of change of f(x) over the interval [-1, 1] is 5.
