Given p(x) = x4 + x3 - 13x2 - 25x - 12
1. What is the remainder when p(x) is divided by X - 4?
2. Describe the relationship between the linear expression and the polynomial?
How do we describe the relationship?
Answers
When a number is divided by a number it results in a quotient and a remainder
E.g. 9 / 4 = 2 remainder 1
9 is the dividend
4 is the divisor
2 is the quotient
1 is the remainder
Same way when a polynomial is divided by a linear expression
E.g.
Ax^2 + bx + c / (x-b) = (x+a) + r
Which can be rearranged to
ax^2 + bx + c = (x+a)(x-b) + r
When x = - a or b, only the remainder is left since either (x+a)(x-b) is 0.
If x = - a or b is substituted into the polynomial and the value is 0 then there is no remainder,
This would suggest (x+a) or (x-b) are factors of the polynomial.
Now apply this logic to these questions
1. Let’s assume (x-4) is a factor, this would mean that when x=4 is substituted into the polynomial the answer would be 0.
This is the case, therefore the remainder is 0.
2. Having seen the logic above (applied using the remainder and factor theorem) the linear expression is a factor of the polynomial.
12. A veterinarian will prescribe an antibiotic to a dog based on its weight. The effective dosage of the antibiotic is given by d ≤ 1∕5w2, where d is dosage in milligrams and w is the dog's weight in pounds. Which of the following graphs displays the effective dosage of the antibiotic?
Answers
Answer:
Graph C. See explanations below.
Step-by-step explanation:
Looking for graph corresponding to d <= (w^2)/5
Take the third graph, which has a solid line (to correspond to the inequality <=, or less than or equal to).
For a dog's weight of 10 lb, the corresponding dose is 20 mg = 10^2/5
for 20 lb, dose = 80 mg (=20^2/5)
...
For 40 lb, dose = 320 mg (=40^2/5).
So this is the correct graph.
The fourth (d) is similar. But the dotted line eliminates the equality in
d <= w^2/5
so not correct.
the price of apples at three different stores is shown below. Store R sells apples for $1.20 per pound. Store S sells 4 pounds of apples for $5.00. Store T sells 3 pounds of apples for $3.48.
which of these is a true statemnt
Store R sells apples at the lowest rate
Store T sells apples at the lowest rate
Store s charges a lower rate than Store T
Store t charges the same rate as Store R
Answers
Store T sells apples at the lowest rate
Step-by-step explanation:
1st We need to make every statement in order of 1 pound. Then We will easily find the lowest rate of apple.
i) R sell 1.20 $ per pound.
ii) S sell 4 pounds for 5$
i.e S sell 1 pound for 5/4 = 1.25$
iii) T sell 3 pound for 3.48$
i.e T sell 1 pound for 3.48/3 = 1.16$
Analysing the above data I get,
Store T sells apples at the lowest rate

Use the given information to find the p-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). With Upper H1: p≠0.377, the test statistic is z=3.06.
a. 0.0022; fail to reject the null hypothesis
b. 0.0011; reject the null hypothesis
c. 0.0022; reject the null hypothesis
d. 0.0011; fail to reject the null hypothesis
Answers
Answer:
Option c: 0.0022; reject the null hypothesis
Step-by-step explanation:
Using a p value calculator, with a z score of 3.06 at 0.05 level of significance for a two tailed test, the p-value is 0.002213. This value is lower than 0.05 thus the result is significant we will reject the null hypothesis.
To calculate the p value by hand, we do this
The test statistic is 3.06. Since the test possesses a not equal to alternative, we look up the test statistic on the z table find the corresponding probability. Thus we have 3.06 - on the z table - 0.99889
Then we subtract from 1 and double it
1-0.99889 = 0.00111 x 2 = 0.0022.

Given ABCD is a parralelogram choose and label approproate coordinates for A, B, C, and D, and prove that the opposite sides of ABCD are congruent. point A is (0,0) point B is (10,0) point C is (12,7) and point D is (3,7)
Answers
Answer:
proved: see explanation below
Step-by-step explanation:
The parallelogram ABCD has cordinates point A is (0,0) point B is (10,0) point C is (12,7) and point D is (3,7).
For the opposite sides of ABCD to be congruent, the slope of the opposite sides would be equal
If AB // CD, BC // AD, it’s a parallelogram.
If slope of AB = CD, BC = AD then it’s a parallelogram.
slope = Δy/Δx
slope AB = (0-0)/(10-0) = 0
slope BC = (7-0)/(12-10) = 7/2
slope CD = (7-7)/(12-3) = 0
slope DA = (0-7)/(0-3) = 7/3
slope DA is supposed to be equal to slope BC
It means the coordinate of D is (2,7)
slope DA becomes= (0-7)/(0-2) = 7/2
Therefore it would be proved that the opposite sides of ABCD are congruent as two pair of slopes are equal
An airplane descends during the last hour of it's flight to prepare for landing. It's altitude changes at an average of -0.15 km per minute for those 60 minutes. (What is the product) How does the elevation of the airplane change in that hour? The elevation of the airplane _________ by ______ km. increases 60 decreases 9 0.15
WILL GIVE BRAINLIEST, THANKS AND FIVE STARS
Answers
Answer:
The elevation of the airplane decreases by 9 km.
Step-by-step explanation:
We use the distance-rate-time formula: d = rt.
Here, the rate is r = 0.15 km/min and the time is t = 60 min. Simply plug these into the formula:
d = rt
d = 0.15 * 60 = 9 km
So, the change in elevation in the last 60 minutes is 9 km. However, note that the rate is negative (-0.15 km/min), which means that the elevation actually is decreasing.
Thus, the answer is: the elevation of the airplane decreases by 9 km.

C.) (-2,8) and (7,-10)

Answers
Answer:
[tex]\boxed{Option \ C}[/tex]
Step-by-step explanation:
[tex]y = -x^2+3x+18\\y = -2x+4[/tex]
Equating both equations
=> [tex]-x^2+3x+18 = -2x+4\\x^2-2x-3x+4-18 = 0\\x^2-5x-14=0[/tex]
Using mid term break formula
=> [tex]x^2-7x+2x-14=0\\x(x-7)+2(x-7)=0\\Taking \ (x-7) \ common\\(x+2)(x-7) = 0[/tex]
Either,
x + 2 = 0 OR x - 7 = 0
x = -2 OR x = 7
For, x = -2 , y is
=> y = -2x+4
=> y = -2(-2)+4
=> y = 4+4
=> y = 8
So, the ordered pair is (-2,8)
For x = 7 , y is
=> y = -2(7)+4
=> y = -14+4
=> y = -10
So, the ordered pair for this is (7, -10)
Solution Set = {(-2,8),(7,-10)}
Answer:
The answer is option C
Step-by-step explanation:
y = - x² + 3x + 18
y = - 2x + 4
Since they are both equal to y we equate them
That's,
- x² + 3x + 18 = - 2x + 4
x² - 5x - 14 = 0
Solve the quadratic equation
x² - 5x - 14 = 0
x² + 2x - 7x - 14 = 0
x(x + 2) - 7( x + 2) = 0
( x - 7)(x + 2) = 0
x - 7 = 0 x + 2 = 0
x = 7 x = - 2
Substitute the values of x into y = - 2x + 4
That's
when x = 7 when x = - 2
y = - 2(7) + 4 y = - 2(-2) + 4
y = - 14 + 4 y = 4 + 4
y = - 10 y = 8
So the solutions are

how do I graph this function
Answers
Step-by-step explanation:
The general form of a sine wave is:
y = A sin(2π/T x − B) + C
where A is the amplitude,
T is the period,
B is the phase (horizontal shift),
and C is the midline (vertical shift).
f(x) = 2 sin(πx)
This is a sine wave with an amplitude of 2, a period of 2, a phase of 0, and a midline of y=0.
To graph, the wave is centered at y=0 and has zeros every half period (x = 0, 1, 2, 3, etc.). Between the zeros, the wave is either a min or max (±2).
The domain of the function is (-∞, ∞).
The range of the function is [-2, 2].
Answer:
For
[tex]f(x) = 2\sin(\pi x)[/tex]
the domain is the real numbers, Range = [-2,2]
Step-by-step explanation:
About the domain, you can take any number, remember that the domain are the "x" that you can plug in on your function, for this case, you can plug in any value and you will have no problem.
Think about it like this, if you have f(x)= 1/x , you can't plug in x=0, but you can plug in all the other numbers, so the domain of that function would be all numbers except 0.
Therefore for
[tex]f(x) = 2\sin(\pi x)[/tex]
the domain is the real numbers.
About the range, it is the "y" axis, which numbers can you reach on the "y" axis, if you graph the function you will see that it is between [-2,2]
Range = [-2,2]

dy/dx = 3/√1-(3x+1)²
Step-by-step exxplanation:
Given the inverse function y = sin^-1(3x+1), to find the derivative of the expression, we will use the chain rule as shown;
Let u = 3x+1 ...1
y = sin⁻¹u ...2
From equation 1, du/dx = 3
from equation 2;
Taking the sin of both sides;
siny = sin(sin⁻¹u)
siny = u
u = siny
du/dy = cosy
dy/du = 1/cosy
from trig identity, cos y = √1-sin²y
dy/du = 1/√1-sin²y
Ssince u = siny
dy/du = 1/√1-u²
According to chain rule, dy/dx = dy/dy*du/dx
dy/dx = 1/√1-u² * 3
dy/dx = 3/√1-u²
Substituting u = 3x+1 into the final equation, we will have;
dy/dx = 3/√1-(3x+1)²

Given the graph of the circle find the equation
Answers
Answer:
(x + 4)² + (y + 1)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = )- 4, - 1) and r = 2 , thus
(x - (- 4))² + (y - (- 1))² = 2² , that is
(x + 4)² + (y + 1)² = 4 ← equation of circle
The equation of the circle will be (x + 4)² + (y + 1)² = 4.
What is a circle?The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.
A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at the (h, k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x – h)² + (y – k)² = r²
From the diagram, the center of the circle is at (-4, -1) and the radius of the circle is 2 units.
Then the equation of the circle will be
(x + 4)² + (y + 1)² = 2²
Simplify the equation, according to the problem.
(x + 4)² + (y + 1)² = 4
The equation of the circle will be (x + 4)² + (y + 1)² = 4.

Step-by-step explanation:
The probability, P(A), of an event A occurring is given by;
0 ≤ P(A) ≤ 1
This means that the probability of an event happening is always between 0 and 1 (both inclusive).
Therefore;
=> 3 / 5 is a valid probability value as;
0 ≤ 3/5 ≤ 1
=> 2 is NOT a valid probability value as 2 is not within the range 0 and 1
=> 5 / 3 is NOT a valid probability value as 5 / 3 = 1.6667 is not withing the range 0 and 1
=> 1.39 is NOT a valid probability value
=> -0.57 is NOT valid. Probability values are not and cannot be negative.
=> 1 is a valid probability value. This just means that the probability that an event will occur is 100% likely.
=> 0 is a valid probability value. This just means that the probability that an event will occur is 0% likely.
=> 0.04 is valid as;
0 ≤ 0.04 ≤ 1
