Answer:
[tex]\sf \bf {remainder}: -\dfrac{3}{8}[/tex]
In order to find remainder:
Follow this short technique:
Set the divisor which is x-½ to zero.
x - 1/2 = 0
x = 1/2
Then insert this following into dividend.
x³ -2x² + 4x - 2insert x = ½
(½)³ - 2(½)² + 4(½) -2simplify
-3/8Answer:
-3/8
Step-by-step explanation:
Let's assume x - 1/2 is a zero of the polynomial :
Substitute x = 1/2 (the zero) in the equationx³ - 2x² + 4x - 2(1/2)³ - 2(1/2)² + 4(1/2) - 21/8 - 2(1/4) + 2 - 21/8 - 1/2-3/8-3/8 is the remainder.

The government conducted a study and collected the given data. use the
data to answer the following questions.
speed (mph) 45 55 65 75
fuel (mpg) 43 45 38 32
find the quadratic regression model that represents the relationship
between speed and fuel. round your answer to two decimal places
The quadratic regression equation is y = -0.02x^2 + 2x - 6
How to determine the quadratic regression?The table of values is given as:
speed (mph) 45 55 65 75
fuel (mpg) 43 45 38 32
Next, we determine the regression equation using a graphing calculator (see attachment)
From the graphing calculator, we have:
a = -0.02, b = 2 and c = -6
A quadratic regression is represented as:
y = ax^2 +bx + c
So, we have:
y = -0.02x^2 + 2x - 6
Hence, the quadratic regression equation is y = -0.02x^2 + 2x - 6

Remark
First take a look at A. It is a pretty good idea always to write the formula you are using before you begin a solution and go step by step from the formula. Also write your givens. I know it sounds like a lot of work. It really isn't. You are creating a habit.
Givens
n = 8
Sn = ?
d = -6
a = 90
Formula
S8 = a + (n - 1)*d
Solution
s8 = 90 + (8-1)*-6
s8 = 90 + 7 * -6
S8 = 80 - 42
S8 = 38
Part B
Here's where the formula is your friend. Let's suppose it is. Then solve for n. If we get an integer for the term number, then all is well. If we don't, and we get some kind of fraction, then 5 is not a member of the sequence.
Givens
Sn = 5
n = ?
d = -6
Formula
Sn = a + (n - 1)*d
Solution
5 = 90 + (n - 1)*-6 Subtract 90 from sides
5-90 =90-90 +(n - 1)*-6 Combine
-85 = (n -1)*-6 Divide by - 6
-85/-6 = (n - 1)-6/-6
14 1/6 = n - 1 Add 1 to both sides
14 1/6 +1 = n - 1 + 1 Combine
15 1/6 = n
But a fraction is not permitted. So 5 is not a member of the sequence

Answer:
Use the pythagorean theorem.
[tex]a^2 + b^2 = c^2[/tex]
The length of one leg, a is 11, and the length of the hypotenuse, the longest side (or c) is 17. Substitute
[tex]11^2 + b^2 = 17^2 \\121 + b^2 = 289\\[/tex]
Subtract 121 from both sides to isolate B
[tex]b^2 + 121 - 121 = 289 - 121\\b^2 = 168[/tex]
Take the square root of both sides to isolate b
[tex]\sqrt{b^2} =\sqrt{168} \\b = 12.961[/tex]

If f(x) = x² — 2x and g(x) = 6x + 4, for which value of x does (f + g)(x) = 0?
4
-2

04
Answer:
-2
Step-by-step explanation:
Given that;
f(x) = x² -2x
and g(x) = 6x + 4
(f + g)(x) = x²-2x+6x+4
:- x² +4x + 4 = 0
x² +2x +2x + 4 = 0
x(x + 2)+2(x + 2) = 0
(x + 2)(x + 2) = 0
:- x = -2

Point S is the midpoint of RT the coordinates of point R and point T are listed below R(-11,-12) T(-7,-4) what are the coordinates of point S
Answer:
S (- 9, - 8 )

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
here the endpoints are R (- 11, - 12 ) and T (- 7, - 4 ) , then
midpoint = ( [tex]\frac{-11-7}{2}[/tex] , [tex]\frac{-12-4}{2}[/tex] ) = ( [tex]\frac{-18}{2}[/tex] , [tex]\frac{-16}{2}[/tex] ) = (- 9, - 8 )
A spinner with a yellow, blue, red, and green section is shown. The arrow is pointing at the yellow section. The fair spinner shown is spun 2 times. The set of possible outcomes are: S = {RR, BB, YY, GG, RB, BR, RY, YR, RG, GR, BY, YB, BG, GB, YG, GY} The number of yellows in the outcome is summarized in the table on the right. A 2-column table has 3 rows. The first column is labeled Yellow with entries 0, 1, 2. The second column is labeled Frequency with entries 9, 6, 1. Using the data from the theoretical probability table, what is the probability of the spinner landing only once on yellow in two spins? 0.0625 0.5625 0.375 1
The probability of the spinner landing only once on yellow in two spins is P = 0.375
How to get the probability?All the possible outcomes have the same probability, so, the probability that in two spins the spinner land only once in yellow is given by the quotient between the number of outcomes that have only one yellow and the total number of outcomes.
All the outcomes are:
{RR, BB, YY, GG, RB, BR, RY, YR, RG, GR, BY, YB, BG, GB, YG, GY}
16 in total.
The ones where the spinner lands only once on yellow are:
{RY, BY, YB, YG, GY, YR}
6 outcomes.
So the probability is:
P = 6/16 = 0.375

P(Head, Diamond AND Head, Heart) = ?
The probability of drawing a head card of diamonds and then a head card of hearts is:
P = 0.003
How to find the probability?
Here we assume that we have a deck of 52 cards, and we want to find:
P(Head, Diamond AND Head, Heart)
This is the probability of drawing a head of diamonds and then a head of hearts.
Remember that for each suit has 3 head cards, J, Q, and K.
Then for the first card, the probability of getting a head of diamonds is equal to the quotient between the number of cards with these properties (3) and the total number of cards (52).
P = 3/52
Then we need to draw a head of hearts, the probability is computed in the same way, but before we drew a card, so now the total number of cards is 51, so we get:
Q = 3/51
Then the joint probability is:
p = (3/52)*(3/51) = 0.003

Decide if this is a permutation or a combination, and then find the number of

The two co-captians can be chosen in 21 different ways.
How many ways are there to choose the co-captains?
If the two co-capitans are equivalent, then we need to find combinations.
