Using synthetic division and the Remainder Theorem, we find that P(a) for P(x) when a=2 is P(2)=4, which is the remainder of the synthetic division.
To find P(a) for the given polynomial P(x)=x⁴+3x³-6x²-10x+8 when a=2, we can use synthetic division. The Remainder Theorem states that the remainder of the division of a polynomial by a linear divisor (x - a) is equal to P(a).
Let's perform the synthetic division:
Write down the coefficients of P(x): 1, 3, -6, -10, 8.Write the value of a below the synthetic division bar: 2.Bring down the leading coefficient: 1.Multiply this coefficient by a and write the result below the next coefficient: 1 * 2 = 2. Add this to the next coefficient: 3 + 2 = 5.Repeat this process for all coefficients.The synthetic division should look like this:
2 | 1 3 -6 -10 8The final number in the bottom row is the remainder, which is also P(2). So, P(2)=4.

After the hairdresser Jenny had 27 centimeters cut off her hair how many decimeters of hair did jenny have cut off
Answer:
2.7 dm
Step-by-step explanation:
You want to know the number of decimeters in 27 centimeters.
SI PrefixesThe SI prefix "deci-" means 1/10.
The SI prefix "centi-" means 1/100.
This tells you that 10 cm = 1 dm.
27 cm = (27 cm) × (1 dm)/(10 cm) = 2.7 dm
Jenny had 2.7 dm of hair cut off.

A bakery has total receipts for the month of $24,150 including sales taxes. if the sales tax rate is 5%, what are the bakery's sales for the month?
a.$24,000
b.$23,000
c.$23,100
d.$22,943
Option B= $23000 is the answer.
Explanation:
Let the bakery's sales for the month be represented by = x
As given, the bakery has total receipts for the month = $24150
Rate of sales tax = 5%
This implies that total monthly sales(x) + sales tax on 'x' = 24150
[tex]x+\frac{5x}{100}=24150[/tex]
[tex]x+0.05x=24150[/tex]
[tex]1.05x=24150[/tex]
x=23000
Hence, the bakery's sale for the month is $23,000
11 black balls and 14 white balls are placed in an urn. two balls are then drawn in succession. what is the probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball?

|A|=11\cdot14+14\cdot13=154+182=336\\\\
P(A)=\dfrac{336}{600}=\dfrac{14}{25}=56\% [/tex]
You randomly select one card from a 52-card deck. find the probability of selecting a black seven or a red three.
The probability of selecting a black seven or a red three will be 1/13.
What is Probability?
The term probability refers to the likelihood of an event occurring.
Given that;
You randomly select one card from a 52-card deck.
Now,
Number of black sevens = 2
Number of red three = 2
So, The probability of selecting a black seven or a red three is;
= (2 + 2) / 52
= 4 / 52
= 1 / 13
Thus, The probability of selecting a black seven or a red three will be 1/13.

The soup can is 6 cm tall and has a radius of 3.5cm. If you were to pull the label off the can in one complete piece,what would the area of the label be ? Use 22/7 for p.
Please help !!!
A)22 sq.cm
B)42 sq.cm
C)132 sq.cm
D)152 sq.cm
Solution:
Radius of cylindrical soup can= 3.5 cm
Height of cylindrical soup can= 6 cm
Area of cylinder =2πrh
So, Area of label of cylindrical soup can=2πrh
Plugging in the value of r and h in the formula
Area of label=2*π*3.5*6
Multiplying the constants, we get
Area=2*π*21
Area=42π
Plugging in the value of π
Area=42*[tex]\frac{22}{7}[/tex]
Multiplying the numerators
Area=[tex]\frac{924}{7}[/tex]
Area=132 sq.cm
Answer: Option (C)
Area of label= 132 sq. cm

The problem is in the picture
Answer:
∠1 and ∠2,
∠3 and ∠4,
∠5 and ∠6
Explanation:
Supplementary angles are angles opposite each other that share the same line that is being dissected by a perpendicular line. The sum of their angles will always equal 180 degrees.
Angles 1 and 2 are an example of such supplementary angles. They share the horizontal line but are being dissected by descending line which creates their angles.
Angles 3 and 4 are more of the same. They share the somewhat-vertical line and are dissected by a different descending line that created them.
Lastly, Angles 5 and 6 are also supplementary angles. They share the somewhat-vertical line and are dissected by the horizontal line, resulting in their angles.
Angles 7 and 8 are not supplementary angles. Rather, they are vertically-opposite angles, or vertical angle pairs, two angles lying opposite each other existing at the point where two lines intersect. These angles have the same exact measurement and their sum will never equal 180 degrees.
The hyperbola (x-5)^2/7 - (y+3)^2/9 = 1 is shifted to the right by 4 units and upward by 3 units. the new center of the hyperbola is
Answer:
( 9 ,0)
Step-by-step explanation:
Given : [tex]\frac{(x -5)^{2}}{7} - \frac{(y+3)^{2}}{9} = 1.[/tex] is shifted to the right by 4 units and upward by 3 units
To find : New center of the hyperbola .
Solution : We have given
[tex]\frac{(x -5)^{2}}{7} - \frac{(y+3)^{2}}{9} = 1.[/tex]
Center of hyperbola is ( 5 , -3)
By the transformation rule f(x) →→ f(x -h) + k it mean f(x) is shifted to right by h unit and k unit up.
Then Center of hyperbola is shifted to the right by 4 units and upward by 3 units.
( 5 , -3) →→ (5 + 4 , -3 + 3
( 5 , -3) →→ ( 9 ,0)
Therefore, new center is ( 9 ,0).

The function F(x) = log0.5 x is increasing. The answer is B. False. Just finished taking the quiz I had guessed.
A. True
B. False
Answer:
The statement is false
B is correct
Step-by-step explanation:
Given: [tex]f(x)=\log_{0.5}x[/tex]
Increasing function.
Log function:
[tex]y=\log_ax[/tex]
If 0<a<1 then y is decreasing function.
If a>1 then y is increasing function.
Now, we compare the given function
[tex]\log_ax\rightarrow \log_{0.5}x[/tex]
a=0.5
0.5<1
If 0<a<1 then y is decreasing function.
Therefore, f(x) is decreasing. But we are given f(x) is increasing.
Hence, The statement is false

Find the absolute maximum and absolute minimum values of f on the given interval. f(x) = 6x3 − 9x2 − 108x + 6, [−3, 4]
Answer:
The absolute maximum of f(x) on [-3, 4] is 138 and the absolute minimum of f(x) on [-3, 4] is -237.
Step-by-step explanation:
To find the absolute extrema values of [tex]f(x) = 6x^3 - 9x^2 - 108x + 6[/tex] on the closed interval [−3, 4] you must:
1. Locate all critical values. We need to find the derivative of the function and set it equal to zero.
[tex]\frac{d}{dx}f(x)= \frac{d}{dx}\left(6x^3-9x^2-108x+6\right)=\\\\f'(x)=\frac{d}{dx}\left(6x^3\right)-\frac{d}{dx}\left(9x^2\right)-\frac{d}{dx}\left(108x\right)+\frac{d}{dx}\left(6\right)\\\\f'(x)=18x^2-18x-108[/tex]
[tex]18x^2-18x-108=0\\18\left(x^2-x-6\right)=0\\18\left(x+2\right)\left(x-3\right)=0\\\\\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}\\x=-2,\:x=3[/tex]
2. Evaluate f(x) at all the critical values and also at the two values -3 and 4
[tex]\left\begin{array}{cc}x&f(x)\\-3&87\\-2&138\\3&-237\\4&-186\end{array}\right[/tex]
3. The absolute maximum of f(x) on [-3, 4] will be the largest number found in Step 2, while the absolute minimum of f(x) on [-3, 4] will be the smallest number found in Step 2.
Therefore,
The absolute maximum of f(x) on [-3, 4] is 138 and the absolute minimum of f(x) on [-3, 4] is -237.
Find the length of AB , given that DB is a median of the triangle and AC = 24.
Answer:
AB = 12 units
Step-by-step explanation:
We are given the following information in the question:
DB is the median of the triangle.
AC = 24 units
Property of median of a triangle:
A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side.Thus, a median divides the side of triangle in two equal parts.Thus, DB divides AC in two equal parts.
Thus, we could say:
AB = BC
We have to find the length of AB.
[tex]\text{AB} = \displaystyle\frac{AC}{2} = \frac{24}{2} = 12\text{ units}[/tex]
Thus, AB is 12 units.
