Select the correct answer.
if p(4) = -16, p(-6) = 0, and P(5) P(-6), which statement must be true?
A. (x + 16) is a factor of p.
B. (x + 4) is a factor of p.
C. (x + 6) is a factor of p.
D. (x – 5) is a factor of p.
Explanation:
p(-6) = 0 means that plugging x = -6 into p(x) leads to p(x) = 0.
If (x+6) was a factor of p(x), then we can say
p(x) = (x+6)q(x)
where q(x) is some other polynomial. Now let's replace x with -6
p(x) = (x+6)q(x)
p(-6) = (-6+6)q(-6)
p(-6) = 0*q(-6)
p(-6) = 0
The value of q(-6) doesn't matter as multiplying 0 with any number leads to 0.
This is all based on the special case of the remainder theorem that says "if p(k) = 0, then (x-k) is a factor of p(x)".
(x+6) is a factor of p.
The answer is option C.
How to solve the function?p(-6) = 0 means that plugging x = -6 into p(x) leads to p(x) = 0.
If (x+6) was a factor of p(x), then we can say
p(x) = (x+6)q(x)
where q(x) is some other polynomial. Now let's replace x with -6
p(x) = (x+6)q(x)
p(-6) = (-6+6)q(-6)

Qual sera o valor do juros correspondente a um emprestimo de 15.000 no prazo de 1 ano, 2 meses e 25 dias em uma taxa de juros composto de 2,5% ao mes
Answer:
470.273
Step-by-step explanation:
Given the following :
Amount of loan = $15,000
Interest rate = 2.5%, compounded monthly
Period = 1 year, 2 months, 25 days
Using the compound interest formula:
A = P(1 + r/n)^(n*t)
A = final amount, p = principal
r = interest rate ; n = number of times Interst is compounded per time period
t = number of time period elapsed
Period = 1 year, 2 months, 25 days since the
Hence, t = 1+(2÷12)+(25÷(30×12))
A = 15000(1 + 0.025 / 12)^(12×1.2361111)
A = 15000(1 + 0.0020833)^14.833333
A = 15000(1.0020833)^14.833333
A = 15000(1.0313515)
A = 15470.273
Hence, Interest equals :
15470.273 - 15,000
= 470.273

647,224 likes/8 hours to calculate a unit rate for likes per minute, what new ratio would you create?
Don’t mind the last question I asked I messed up on the wording, it’s the same as this one but with messed up words.
Answer:
the new ratio is 1348 likes per min.
Step-by-step explanation:
given:
647,224 likes/8 hours
find:
calculate a unit rate for likes per minute
= 647,224 likes x 1 hour
8 hours 60 min
= 1348.33
therefore,
the new ratio is 1348 likes per min.
Solve x -8y = 15 for y.
y =?
(Use integers or fractions for any numbers in the expression.)
Answer:
y = -15/8 + x/8
Step-by-step explanation:
x - 8y = 15
Solve for y.
Subtract x from both sides of the equation - -8y = 15-x
Divide -8 from both sides of the equation - y= -15/8 + x/8
(The negative from the x and 8 cancel out and become positive)
Answer:
y=x-15/8
Step-by-step explanation:
Subtract x from both sides
Divide both sides by −8.
Dividing by −8 undoes the multiplication by −8.
Divide 15−x by −8.

Question 1 Solve the absolute value equation |x| − 2 = 5 to find the distance Mary can walk forward, x, in 5 seconds. Group of answer choices x = 7 m and x = −7 m x = −7 m and x = 3 m x = −3 m and x = 7 m x = 3 m and x = −3 m
Given:
The absolute value equation is
[tex]|x|-2=5[/tex]
To find:
The distance Mary can walk forward, i.e., x.
Solution:
We have,
[tex]|x|-2=5[/tex]
Add 2 on both sides.
[tex]|x|-2+2=5+2[/tex]
[tex]|x|=7[/tex]
[tex]x=\pm 7[/tex]
[tex]x=-7[/tex] and [tex]x=7[/tex]
Here, negative sign represents the distance Mary can walk reverse direction.
Therefore, the correct option is A.

1.9 X 0.46
Answer anyone?
1.9 × 0.46 is equals to 0.874
What is a decimal ?
A decimal can be represented by a dot which separates the whole part and the fractional part of a given number.
Multiplying decimals can be simplified if we take out the decimals and just multiply them as whole numbers
∴ 1.9 × 0.46 ⇒ 19 × 46
= 874
Now the two numbers had total 3 digits after the decimal places.
So, in our obtained result we will put the decimal 3 digits before starting from the rightmost digit.
∴ 874 ⇒ 0.874

A Man buys two mobiles for Rs. 2,000 each. He sells one of
them at 10% profit and other at 5% loss, what percent of
profit or loss is there in the total transaction?
Answer:
2.6%
Step-by-step explanation:
CP of each phone =2000
total cp = 4000
in 1st case
profit = 10 %
so,sp = cp + 10 % of xp
= 2000 + 10/100 ×2000
= 2200
in 2and case
loss =5%
so sp=cp - 5% of cp
=2000 - 5/100 × 2000
=1900
so total sp = 4100
so profit % = sp - cp/cp ×100%
= 2.5

The given series 1, -1,... is arithmetic progression series whose pattern is a, a +d, a + 2d, a + 3d + a + 4d , ....
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression is more often used, for instance in the sum of natural numbers.
1, 2, 3, 4, 5, 6, 7, and 8 are natural numbers.
The difference between any two subsequent terms is now the same: d = 2-1 = 3-2.
Given,
1 , -1 , ...
If we subtract the second term from first
-1 - 1 = -2
So, a common difference between the series will be -2
Now,
Third term = a + 2d = 1 + 2 (-2) = -3
Fourth term = a + 3d = 1 + 3 (-2) = -5
Fifth term = a + 4d = 1 + 4 (-2) = -7
Hence the general rule will be a, a +d, a + 2d, a + 3d + a + 4d , ....

how do you sovle this 5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x
Answer: X=-3
Step 1) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5*(x-4)+3*x-9*x-(6-(2*x+5)+8*x)=0
Step 2) ((5 • (x - 4) + 3x) - 9x) - (6x + 1) = 0
Step 3) Pull out like factors : -7x - 21 = -7 • (x + 3)
Step 4) -7 • (x + 3) = 0
Step 5) Solve : -7 = 0 This equation has no solution.
A a non-zero constant never equals zero.
Step 6) Solve : x+3 = 0
Subtract 3 from both sides of the equation :

Function P is defined as P (x) = x ^2 . Explain why P (2) + P (3) isn't equal to P (5) .
Answer:
P(x) = x + 2
Piden: A = P(P(P(P(3))))
P(3); x = 3
P(3) = 3 + 2 = 5
A = P(P(P(P(3))))
A = P(P(P(5)))
P(5); x = 5
P(5) = 5 + 2 = 7
A = P(P(P(5)))
A = P(P(7))
P(7); x = 7
P(7) = 7 + 2 = 9
A = P(P(7))
A = P(9)
P(9); x = 9
P(9) = 9 + 2 = 11
