Answer:
229 is the remainder.
Explanation:
In order to find the remainder, insert the value of x in the equation.
Given equation:
[tex]\sf p(x) = x^4 - 27[/tex]Given x value:
x - 4 = 0x = 4Find remainder:
[tex]\sf p(4) = 4^4 - 27[/tex]
[tex]\sf p(4) = 256 - 27[/tex]
[tex]\sf p(4) = 229[/tex]
Answer:
229
Step-by-step explanation:
Here we are given a polynomial p(x) and we need to find the remainder when it is divided by (x-4) . As we know that if a polynomial, say [tex]g(x)[/tex] is divided by [tex]x-a[/tex] then the remainder is [tex]g(a)[/tex] .
Firstly equate [tex] x -4[/tex] with 0 , we have;
[tex]\longrightarrow x -4=0\\[/tex]
[tex]\longrightarrow x =0+4\\ [/tex]
[tex]\longrightarrow x = 4 [/tex]
Now substitute [tex] x =4[/tex] in [tex]p(x)[/tex] ,
[tex]\longrightarrow p(x)= x^4-27\\[/tex]
[tex]\longrightarrow p(4)= (4)^4-27\\[/tex]
[tex]\longrightarrow p(4) = 256 - 27 \\[/tex]
[tex]\longrightarrow \underline{\underline{\boldsymbol{ p(4) = 229}}}[/tex]
Hence the remainder is 229 .

What is relative frequency?Relative frequency refers to the percentage or proportion of times that a given value occurs within a set of numbers, such as in the data recorded for a variable in a survey data set.
We get
Total (own fish) = 0.04 + 0.08 = 0.12
So, own fish = 0.12
= 12%
12% of the people surveyed own fish.

3. Use Structure Shari is drawing a tree diagram
to represent the sample space of rolling a
12-sided game piece and spinning the pointer of
a 4-section spinner. Does it matter if Shari starts
the tree diagram with the game piece outcomes
or the spinner outcomes? Explain.
The sample space of Shari's tree diagram is the total possible outcomes of rolling the game piece and spinning the pointer.
It doesn't matter if Shari starts with the spinner or the game piece
How to determine the tree diagramThe experiment involves:
Rolling a 12-sided game pieceSpinning the pointer of a 4-section spinnerIf Shari starts with the game piece, the sample size (n) would be:
n = 12 * 4
n = 48
If Shari starts with the spinner, the sample size (n) would be:
n = 4 * 12
n = 48
Notice that the sample size remains unchanged irrespective of what he starts with
Hence, it doesn't matter if Shari starts with the spinner or the game piece

The possible outcomes of the fair coin and the dice is the sample space
The list of possible outcomes is: {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}The probability of getting a head and a 3 is 1/12How to list the possible outcomesThe items are given as:
Coin = 1
Dice = 1
The sample space of both items are:
Coin = {H,T}
Dice = {1,2,3,4,5,6}
So, the list of possible outcomes is: {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}
The probability of getting a head and a 3From the above list, there is only one outcome that has a head and a 3 out of 12 possible outcomes

Angle MON = y
Prove that angle BMN = 1/2 y
Explanation:
We can make use of the symmetry of the problem and properties of similar triangles.
Here's a "paragraph proof."
Draw line OP perpendicular to chord MN, such that P lies on line MB. Let the point of intersection of OP with chord MN be designated point Q. Line OP bisects angle MON, so has measure y/2.
Triangles OPM and MPQ are similar (by AA similarity; both right triangles contain angle OPM), so angle QMP ≅ angle MOP. As we observed above, angle MOP has measure y/2, so angle QMP has measure y/2.
Angle BMN is another name for angle QMP, so it has measure y/2.
__
Additional comments
By the HL congruence postulate, the perpendicular bisector of chord MN divides triangle MON into two congruent right triangles. (OM≅ON, MQ≅NQ). That means ∠MOQ≅∠NOQ, so OQ bisects angle MON, as we say above.
__
Another way to come to the desired conclusion is to recognize that for any point X on long arc MN, angle MXN will have measure y/2. (inscribed angle theorem) This remains true in the limit as X approaches M. As X approaches M, secant XM approaches tangent line MB. So, in the limit, angle BMN is y/2.

If the initial population of the bacteria is 100, then the population of the bacteria after 180 hours will be 800.
What is an exponent?Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

Explanation and Answer:
The graph of y=[tex]x^2[/tex] is a parabola (it looks like a u) that intersects the graph at the origin. These are all shifted variations of that graph, so from that you can figure out their formula by visualizing it.
You can also try substituting numbers into the equations and drawing a graph from that.
Graph A is the y=x^2, shifted to the left, so it becomes [tex]y=x^2+x[/tex]. It's +x because now negative numbers can be gotten from the equation, as compared to before when x^2 gives only positive numbers.
Graph B is [tex]y=x^2+3x[/tex] . Similar to graph A, but now it moves down by more units, because of the 3x.
Graph C is [tex]y=-x^2+2[/tex]. Imaging y=x^2 flipped, it changes from looking like a u to n. That's y=[tex]-x^2[/tex]
Graph D is [tex]y= x^2-x[/tex]. The opposite of Graph A.

If ΔRST congruent to ΔNPQ, which of the following is true? A. ∠R congruent to ∠P B. ∠R congruent to ∠Q C. ∠T congruent to ∠P D. ∠T congruent to ∠Q
Answer:
Step-by-step explanation:
The order of the expression for congruent shapes indicate the
corresponding vertices between the two shapes that are congruent.
The option which is true is D. T = Q.
Reasons:
The given statement is; ΔRST ≅ ΔNPQ
By Corresponding Parts of Congruent Triangle are Congruent, CPCTC, we
have; The sides on ΔRST are congruent to the corresponding sides of ΔNPQ
Therefore;
RS ≅ NP
RT ≅ NQ
ST ≅ PQ
By CPCTC, we have that the angles on ΔRST are congruent to the corresponding angles of ΔNPQ
Therefore;
∠R ≅ ∠N
∠S ≅ ∠P
∠T ≅ ∠Q
Which gives, by definition of congruency;
∠R = ∠N
∠S = ∠P
∠T = ∠Q
Therefore, the true statement is D. T = Q.

What is the measure of ∠A in the image below?
Answer:
A
Step-by-step explanation:
3x and x + 30 are vertically opposite angles and are congruent , then
3x = x + 30 ( subtract x from both sides )
2x = 30 ( divide both sides by 2 )
x = 15
Then
∠ A = 3x = 3(15) = 45°
See <A and x+30 are opposite angles .
We know that opposite angles are equal
so
3x=x+302x=30x=15Now
<A=3x=45°Option A is correct

A square and a rectangle have the same area. The square has side length 8 in. The length of the
rectangle is four times its width. What is the length of the rectangle?
The first step we take is to find the area of the square since the area of the square is equal to the area of the rectangle
[tex]area-of-rectangle = area- of-square\\area-of-rectangle = 8*8 = 64in^2[/tex]
Another fact we know is that the length of the rectangle is four times the width.
L = 4W
L: Length's lengthW: Width's lengthNow let's put the variables, found above, into the format to find the area of the rectangle
[tex]area-of-rectangle = L * W, (L = 4W)\\area-of-rectangle = 4W * W\\\\64 = 4W^2\\16 = W^2\\\\W^2 = 16\\\\W = 4[/tex]
Since the Width is 4, L = 4 * W = 4 * 4 = 16 in.
So the length is 16 inches

What was the price yesterday?
Answer:
$820.00
Step-by-step explanation:
x = price yesterday (initital price)
If it is 67% off, then the price is 33% of the initial.

divide .37 on both sides
x = 820.00
The price of the suit yesterday is $820.00.

As with other forms of direct and inverse variation, the "constant of variation" (k) is the constant multiplier in the equation. "Varies directly" means the independent variable is in the numerator. "Varies inversely" means the independent variable is in the denominator. The variation equation can be solved for missing values of constants or variables.
The equation for "varies directly with v and w, and inversely with z" means the equation is of the form ...
y = k·v·w/z
Then the values of v or w are ...
v = y·z/(k·w)
w = y·z/(k·v)
__
a)k = y·z/(v·w) = 5·24/(12·14) = 5/7; the equation is y = 5·v·w/(7·z)
b)w = y·z/(k·v) = 18·8/(10·4) = 18/5; the equation is y = 10·v·w/z
c)k = 3/2 (read from the equation); y = (3/2)v·w/z = 3·16·24/(2·6) = 96
d)k = 8 (read from the equation); v = y·z/(k·w) = 20·2/(8·6) = 5/6
e)y = k·v·w/z = 6·12·7/15 = 168/5; the equation is y = 6·v·w/z

to solve m + 9 = 45, should you add or subtract 9 from both sides of the equation
Answer:
subtract 9 from both sides
Step-by-step explanation:
m + 9 = 45 ( subtract 9 from both sides )
m = 36
Answer:
Subtract
Step-by-step explanation:
You should subtract since the equation says to add.
You basically do the opposite of what it says.
For example, if it was m - 9 = 45 you would add 9 on both sides, but in this case, you would subtract since its m + 9 = 45
m + 9 = 45
subtract nine by 9 and 45:
m = 36
36 + 9 = 45

Only the "90"s match up, but everything else does not. We need to have three pairs of congruent angles to be able to use the angle angle (AA) similarity theorem.
