The value of d that makes (x - d) a factor of p(x) is d = -5.
Given that we need to find the value of d if (x-d) is a factor of the polynomial [tex]\mathrm{p(x)= 2x^3 -dx^2+(1-d^2)x+5}[/tex].
If (x - d) is a factor of the polynomial [tex]\mathrm{p(x)= 2x^3 -dx^2+(1-d^2)x+5}[/tex], it means that if we substitute (x = d) into the polynomial, the result should be equal to zero.
In other words, p(d) = 0.
Let's find the value of d by setting p(d) to zero and solving for d:
[tex]\mathrm{p(d)= 2d^3 -d\cdot d^2+(1-d^2)d+5}[/tex]
To find d, we set p(d) equal to zero:
[tex]\mathrm{ 2d^3 -d\cdot d^2+(1-d^2)d+5 = 0}[/tex]
Now, let's simplify this equation and solve for d:
0 = 2d³ - d³ - d³ + d + 5
0 = 2d³ - 2d³ + d + 5
0 = d + 5
Now, isolate d:
d = -5
So, the value of d that makes (x - d) a factor of p(x) is d = -5.

From the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
10p - 8 >12
10p > 12 + 8
10p > 20
p > 2
p ∈ (2, ∞)
Thus, from the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.

Solve for 'p'. Show all work: 2(-4x + 8) ≤ 20
Answer: Answer: x≥ −1 /2
Step-by-step explanation:
Answer:
x ≥ -1/2 or x ∈ [-1/2, +∞)
Step-by-step explanation:
2(-4x + 8) ≤ 20
divide both sides by 2
-4x + 8 ≤ 10
move 8 to the right
-4x ≤ 10-8
-4x ≤ 2
divide both sides by -4. Flip the sign since a negative value is being divided

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each 10K participant. Her goal is to raise $9,500.If x represents the number of participants in the 5K race and y represents the number of participants in the 10K race, the linear equation for the given scenario is
Answer:
20x + 45y = 9500 is the linear equation for given scenario
Step-by-step explanation:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
Therefore, the linear equation for given scenario is found
Answer:
20x + 45y = 9500
yes/no: no
Solution:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
If eve raises exactly $9,500, it is NOT possible for there to be 220 participants in the 5K race.

I hope this helps at least. :)
Simply put, expressing a radical in its lowest extreme form implies simplifying it and that there are no more squared roots, cube roots, 4th roots, and so on to find. This also entails eliminating any radical from a fraction's base, and further calculation can be defined as follows:

- 3x - 10 = 32
X = 14
X = -14
X = -10
x =10
Answer: -14
Step-by-step explanation:
-3x-10=32
Since the 10 is negative you have to add 10 on the right side of the equal sign. you add 10 to the negative 10 and it cancels out and becomes zero. Then you have to add 10 to the 32 and it becomes 42. Divide the 42 by negative 3 and you get -14.
I have a cockroach problem in my living room. Don't ask how but I counted 64 cockroaches today. And they are
growing at a rate of 25% every day.
How many cockroaches do you think I'll have after three days?
If they are growing at a rate of 25% every day you can expect to have approximately 100 cockroaches in your living room.
What is growth rate?Growth rate refers to the rate at which something (such as a population, a quantity, or a value) increases or decreases over a certain period of time.
Assuming that the growth rate is compounded daily, we can calculate the number of cockroaches you will have after three days using the formula for exponential growth:
[tex]N = N_0(1 + r)^t[/tex]
Where:
N₀ is the initial number of cockroaches (64 in this case)
r is the growth rate (25% or 0.25 in decimal form)
t is the time in days (3 in this case)
N is the number of cockroaches after t days
Plugging in the values, we get:
[tex]N = 64(1 + 0.25)^3[/tex]
[tex]N = 64(1.25)^3[/tex]
N = 64(1.5625)
N = 100
Thus, after three days, you can expect to have approximately 100 cockroaches in your living room.

given cot A= 40/9 and that angle A is in quadrant 1 find the exact value of sec A in the simplest radical form using a rational denominator
Answer:
41/40Step-by-step explanation:
Given cotA = 40/9
1/tanA = 40/9
tanA = 9/40
According to SOH, CAH, TOA
tan A = 9/40 = opposite/adjacent
Get the hypotenuse
hyp² = opp²+adj²
hyp² = 9²+40²
hyp² = 81+1600
hyp² = 1681
hyp = √1681
hyp = 41
Het sec A
sec A = 1/cosA
Since cos A = adjacent/hypotenuse
cos A = 40/41
secA = 1/(40/41)
SecA = 41/40
Hence the exact value of secA is 41/40
